The future of CHademo

BoatMad

while this is from 2013, its an interesting comment

I think new purchasers should be warned of this situation, as currently they are buying into old standard.

Should we care? Seems more like an issue for the manufacturers than the owners?

As you pointed out, the article is from 2013 and CCS is still patchy across this country. Does that mean that the forecasted doomsday for Chademo was premature?

Worst case scenario CCS starts to take hold and Chademo goes into decline over the next 5-10 years.... so what?
I dont think that means that Chademo users are all of a sudden going to find themselves with cars that they cannot charge at the rapids.

@BoatMad: You seem to know a thing or two about chargers and EVSE's etc. Is it technically possible to have an adaptor that would allow you to connect a CCS charger to a Chademo connection which would be an "easy" transition over to CCS if Chademo does in fact die in time.

personally CCS is a very poor " compromise " system , to add a very simple DC option to a AC plug. The signalling protocol is far inferior ( in that its very complex) to Chademo ( and others) that use CAN bus in the connector to communicate between charger and battery management systems

but yes , Chademo to CCS is entirely possible, the other way round is far more complex. edit , well in reality both systems are complex to convert. Its actually easier to build three way DC fast chargers then convert from on etc the other .

the big mistake in my view is until recently CHademo was a private protocol. The Japanese dont do " open" solutions well.

ChaDeMo II is already in the works and can support I think up to 150 Kw.

CCS was/is unnecessary .

yes but CCS is the accepted DC standard in Europe by the Brussels mob, Chademo is not , and no other car other then nissan is using it ,. even Tesla is going CCS

thats not good and suggest Chademo is going to fail in Europw

It was a very poor decision. ChaDeMo works. But the E.U and U.S wanted to make their own standard.

During my Tesla test drive I was told that it uses Chademo, and I was shown the Chademo adapter. Same in Switzerland, according to a driver who I met, but I am not sure about the rest of Europe.

In any case, I expect all future new rapid chargers in Ireland, UK, and in Europe to still include Chademo, perhaps for another 8-10 years, because it would be counterproductive to exclude the largest share of the market from being able to use them. At the same time, I expect those chargers to include CCS in addition to, but not instead of Chademo.

I strongly disagree.

Homeplug GreenPhy (which CCS uses for signalling) is fairly simple from my perspective at least. It's basically a subset of HomePlug AV. PLC makes sense in the long term as well because it can be used for home automation, vehicle to grid communication for demand response etc. GreenPhy is even forward compatible with homeplug AV.
CAN bus is being phased out in the vehicle favor of IP based solutions anyway over the next few years.
CCS can handle a much wider array of charging scenarios in one plug, from multi-phase AC to 170kW DC (soon to be 350kW).
Chademo's connector is both bulky and fragile. causing reliability issues and taking up a ton of space in the vehicle.

Most of the rapids I've seen installed in germany these days are either Type 2 / CCS or CCS only. CCS only rapids are between €3-5k cheaper than the multi-standard. Tesla has also installed CCS at a lot of their supercharger locations due to requirements from german law.

Chademo (rapid) to CCS (vehicle) is largely a pain because you'd need to independently power your adapter.

BoatMad wrote: »

Take it from someone who has owned vehicles with both connectors. I'd pick CCS over Chademo every single time. It's physically easier to use, the plugs/sockets are more durable, all charging is done it the one place (when I loan my leaf to someone they need a walkthrough on rapid charging, with the i3 they figure it out very easily) and then there's cheap 22kW CCS rapids for around €4k that I can put in the house.

I'm impressed, it seems that CCS is a big improvement and it makes sense to shift to this standard. I hope future LEAFs and Outlanders will support it.

Tesla sell a Chademo adapter. However they have also just joined the CCS forum as a "platinum" member or whatever. I'd expect the Model 3 to come CCS equipped in europe and retrofitting of existing superchargers and vehicles.

2018 is the next review on a european level. I'd expect all vehicles to be required to use CCS from then on.

The lack of CCS in large parts of the country will need to be resolved first though. There arent enough Chademo not to mind CCS so I dont think 2018 is going to change much.

The numbers in Ireland are so small nothing will change in the next few years.... EU Law or not.

BoatMad

This isn't the place for a discussion on the merits of can bus signalling over poweline

As for home automation. The standards are in an absolute mess. So any connection with HA is as much a disadvantage as it might be an advantage

Can bus is simpler to implement

The key point is that chademo is basically finished in Europe and that leaves existing leaf owners in s quandary as their cars age ( and especially if they want to go abroad )

Note that I agree the connector for ccs is better. The chademo is too big awkward and heavy

Note there is no need to power any ccs to chademo adapter separately. The power can be derived from the supply ( easy ccs to chademo more complex the other way round )

This (isn't) ChaDeMo II but a new plug. So the argument that CCS plug is better doesn't hold up for much longer. I think the updated ChaDeMo plug is actually better than CCS.

Whatever standard is being pushed in Germany is not because it's better but because it supports their home Auto industry.

"Why install chargers suitable for Japanese cars ? we'll just install CCS and people have no choice but to buy German or American."

The south korean brands are going CCS too. Both Kia and Hyundai's next EVs will be CCS.

Nissan is the sole holdout. My information is that the European Mk2 Leaf will go CCS. So the 30kWh Leaf could be the last Chademo vehicle sold in europe.

I would concur. Chademo is dead in Europe as a way forward. IT may also impact currnt leaf resale value too

Would Nissan willingly make their market-leading next Leaf incompatible with ca 70% of the installed chargers in Europe? That would also mean giving up a serious commercial advantage they have built over the years by being the first and the original investors. Unless they have plans to upgrade all their Chademo chargers into CCS, and so to roll out the carpet for the German brands at no cost to them.

I suppose anything is possible. What is your source of the information about Leaf Mk 2 abandoning Chademo, if you don't mind sharing?

CCS is now more than 80% of the install base of Chademo in europe. And growing quicker. Large infrastructures like Germany's new rapid charging network are effectively CCS only. I went to Berlin last summer on CCS rapids... a journey that at least at the time wasn't possible for a chademo vehicle. Now of the 500 new rapid chargers in germany being built before the end of June, 300 are CCS/AC only and 200 are multistandard including chademo.

The Leaf is the best selling EV in Ireland in large part because of the infrastructure. The Leaf is not remotely as dominant outside Ireland and the UK.

Rafal wrote: »

An engineer who works for Nissan R&D. But it also a fairly obvious move. Nissan is the only serious member of the Chademo association. Mitsubishi won't have another BEV out until 2018, with the koreans going CCS in europe the writing is on the wall. New EU regulations are due to harmonise around one standard in 2018... maybe only one year into the mk2 Leaf's life. Also CCS wasn't really launched proper until less than three years ago. Chademo was the only option for the gen 1 Leaf because CCS didn't exist yet.

BoatMad

I would agree with cros13, its likely CCS will be made mandatory by the EU by 2018 , ANyway its the right thing to force a single standard. like betamax and VHS, its not about who was technically better ( which was clearly betamax), its was the one that got multi vendor support that won the day

The thing is will Nissian offer a pay for conversion to CCS for existing leafs in the future, its has been speculated on elsewhere

No idea. But the replacement cost of the unit that contains the chademo connector and J1772 on a Leaf costs about €2k as a part. Plus you'd need a new computer to talk to the CCS rapid.

Lets say Chademo is dead from 2018 onwards and new LEAF's come with CCS.... how is that going to play out for the ESB network.

The majority of their users, who they hope to get revenue from, are Chademo.
They have completed their charger rollout and wont be investing anything more until EV uptake increases significantly, which we know isnt going to happen over the next 3-5 years unless a government drastically change direction... unlikely with the hodge podge government we have now.

There might be a few exceptions where ESB replace old chargers but by and large the network we have today is the network you will have for the foreseeable future(5 years maybe?) which wont be any good for CCS users.

I think the commercial reality in this country will be an overriding factor here long after any EU decisions are made in 2018. i.e. Chademo and CCS will have to live side by side for many years to come.

I believe most of the older Chademo only chargers will be swopped out. The first to go are ones that have no RFID capability.

The big issue is definitely the issue of " what next "

It would be an appalling vista to have no further expansion , even if EVs grow at a 300 plus organic growth per year , that would double the population and put the infrastructure under tremendous strain and then lead to a drop off in EV adoption.

Nor is commercialisation in the near future any solution , the current user base is way too small and you will have a drop in usage as users take up home charging , which will further depress usage charges.


The key know is to get active government involvement, to both subsidise the charger costs , resulting in free usage for a stated period and to provide investment to fund the expansion the network as the number of EVs grow.

Commercialisation can then be introduced gradually as the network is shown to mission critical and fit for purpose

All sound thinking except for the swap outs of Chademo. Do you really think they will swap out an old charger and replace it with a CCS/AC only charger?.... I doubt that somehow.

Upgrade the charger to the latest for sure, but why alienate the majority of the users by not putting in Chademo. This 2018 decision is a long way off in reality as it will probably be a phased initiative and they cant just cutoff existing users if they want to have any hope of keeping EV sales alive and of commercialising the network.

I've spoken to ESB business development and they have said the network is what it is and isnt going to build out anymore until usage increases. You are right it needs government and ESB to sit and discuss a sensible approach.... i.e. government stump up money which wont be easy with this government.... it could be a long wait.

No they are upgrading to dual CCS and Chademo

I agree current expansion is finished no new installations planned.

I don't agreed it will be any harder then any other gov to get listened to. Simon Coveney might be a way in. The imposition of serious fines from the EU will focus minds veer the next few years

If they are dual CCS/Chademo then we are fine... long live Chademo!
To be honest, I dont care if Chademo dies or not over the long term just as long as no rash decisions are made about removing them in the medium term.


The issue with the government isnt getting them to listen... politicians are very good at listening... its getting them to implement and having them in government long enough to implement.... this government could last 5 months or 5 years and thats an issue.

Correct me if I'm wrong, but there is no E.U legal requirement to ban ChaDeMo ? there was only a proposal ?

The ESB have not abandoned new DC installations, There won't be any more AC installations for the foreseeable future.

The ESB may perhaps install multiple chargers on the busiest sites in 2016.

I suppose the 2018 review is where the "ban" might come from. They might dictate that all new cars have CCS. It doesnt ban Chademo, just makes it weaker over time. Then again, they might allow both standards proceed. We'll just have to wait and see.

On ESB... they said they were not adding any new chargers until usage increases. They did say some sites have queuing issues around Dublin and they might increase capacity in a few sites but the network would still be the same as such.... no new sites.

The EU parliament tried to ban non CCS installations recently , it wasn't successful , it's expected that CCS will however be one the mandated standard by 2018. That doesn't prevent dual installations , but it's unlikely Nissan , as the only European provider with a stake in Chademo will continue with that standard n Europe , the expectation is the next generation Leaf will be CCS

As of now , the esb is not engaging in any expansion of the DC or AC charging infrastructure. The rollout is finished for the time being , they have announced the last few installations recently.

They are engaging in swoping out some models of FCP

this strategy has been confirmed during the very recent meeting with the IEVOA and ecars and has been also confirmed privately to me.

The next step will be a decision n the extent and nature ( if any ) of commercialisation and will be driven primarily by government policy on the incentivisation of the EV market ( or not as the case may be )

There is no commitment at present to extend the number of fcps on busier sites outside of any decisions as I have outlined above

A part of this , is the data the esb that the esb has points to people using fcps instead of charging at home , so" busier sites" is a current poor metric. The esb believes the free access is skewing statistics and in my view have a mistaken belief in commercialisation as a way to counter this.

Hence the busy sites metric is not currently a sound basis to expand FCPs

As I've said there is no capital allocated to expansion and nothing will be decided one way or the other until the esb see the outcome of the current delberations combined with the incoming Govs overall policy

Which is sensible if you are the esb, after all they mightn't even own it in the future

Free usage of the chargers promotes abuse as I saw countless times at Naas. And I'm sure this behaviour extends throughout the Island.

I gather you are not a big user of the FCP network, at this stage I have actually visted one third of all FCPs.

I see no evidence of " abuse" at FCPS, if people want too charge to 100% at an FCP thats entirely correct.

Charging is a very crude way of solving the issue and as you have said in other threads you dont care because you dont use them much.

Buts lets leave for once The " Im all right jacks' arguments out of the discussion

What specific issue do you see at FCPS ( and only FCPs for the moment ) aside from non EV issues , like ICE-ing

You've used a lot of the chargers for free and think you should be entitled to it because you decided to buy an EV and want to drive xxxx kms for free ?

So enough with the "alright Jack" lol

Yes I encountered leachers at Naas quiet regularly with the attitude it's free and I'll use it because I don't have to pay for it and people made me know it too and then told to get stuffed (putting it rather mildly) when I suggest they use their home charge points.

Free electricity hasn't caused an explosion in EV sales in the last 4 years so I doubt it's the sole factor in everyones decision to buy an EV.

You want a greater EV uptake then convince the Government to tax all newer diesels out of the market. Because most Irish drivers are not interested in the environment or what powers a car, if the Diesel costs a lot more to buy and costs a lot more to tax then this is a great way to get people to buy electrics and having a lot more models to choose from.

You think the sole issue is not enough DC charger ? you don't think people use them because they're free ?

Increased taxes on "new" ICE's both petrol and Diesel, motor tax etc can go towards funding the Infrastructure and maybe keeping usage free for people who won't charge at home.

As the charger probably knows the state of the car battery, they could be charged based on that:
* 0-80% - free
* 80-90% - 10ct/minute
* 90%+ - 25ct/minute.

That wouldn't make much difference for honest users, while making sure the chargers aren't occupied unused.

0-80% is still free again, promoting abuse.

Remember as car batteries grow 80% will take much longer to reach.

The 30 Kwh also charges a lot faster at 80% than the 24 Kwh.

Hold your horses

(a) There will not be ANY tax regime that penalises diesels or petrols anymore then the current regime, so lets take that off the table. its simply not possible in the current Gov regime . No point continuously flogging that horse

(B) The evidence is there was a significant halt in EV sales in Nov- december due to the announcement of charging

(C ) everyone accepts that ultimately EVs can not have free electricity . The point is at 2000 vehicles and a less then mission critical infrastructure, poor range and expensive vehicles, they market needs to be expanded before you commercialise it

The ESB was attempting to monetise the network rather then commercialise it and they were doing so for mainly strategic reasons rather then economic


The fact that people use FCPs instead of charging at home, is at this stage not a reason to charge all legitimate users of EVS simply to crack a small nut.


We have to look at EVs strategically , if you and I and the Gov are seriously interested in growing the EV market we are going to need

1. incentives to buy them
2. incentives to run them

But yes just as in Norway, once you reach a target , you scale back those incentives , just as Norway is doing today .


for specific incentives I would see

1. commit to free provision electricity from SCPs and FCPS for 5 years , reviewed annually or until 20% of all cars are EVs. excessive use of FCPS can be controlled by time limits and limits too same site repeat charging

2. allow access to bus lanes for a introductory period of 3 years reviewed annually

3. I would not abolish motor tax, all cards use road resources and should pay

4. no tolls for a period of 3 years , reviewed annually


The fact is the FCP network is NOT busy as a whole. one or two sites are, but in the last 4 weeks, having used a large number of FCPS, I waited only once at Lucan. ( people waited on me at Carlow)

FCPs for example in Athlone , Kilbeggan, Carlow, wicklow, Cullenmore wexford , talbot, templeville , enfield , were all unoccupied everything I arrived there to charge


Hence this isn't a serious problem at this point in the market share of EVS on the road. There may be a problem here and there , but it's not a general problem

I dont see why a person wanting 90% capacity should pay anything different to a person wanting 80%, time based charging is inherently unfair, imagine if you paid based on the time at a petrol pump , its nonsense

the fact remains , hogging at FCPs is not a general issue irish people are great at making problems out of basically non existent situations.

if and when hogging is an issue , then we need solutions, that would be handled by a gradual introduction of KWh unit based charging , preferably back through a retail electric provider so that retail competition can be introduced, with provisions for guest style access.

But ONLY when we have a critical uptake of EVs, otherwise we kill the market before it gets started.

not a like for like comparison that..... the speed at which you fill your petrol/diesel is decided by the pump and is linear and its the same for everyone.... you dont need EV charging explained to you so i think you get the point.

It needs to be some compromise of kWh's and time.

I do agree with you though that I havent seen any queuing/hogging in the 10+ separate FCP's I've used in the last 2 weeks or so. As you said, I'm sure there is queuing in select places at select times but its not a general issue.

people should not be penalised simply by the technology in their car.

electricity is billed by KWh , and it should be no different for EVs. A person with a first generation EV should pay exactly the same as the person with the latest whizz bangery

The issue over delays at FCPs is a issue of sufficient infrastructure FCPs. its not a reason to " limit " access. Think of FCPS like petrol pumps, there should be loads.

Time at an FCP should not become the issue , the number of FCPs should

Fair enough, but thats looking at the world through rose tinted glasses. Your strategy is fine long term if you can get the funding to add new chargers. Thats not happening right now or the foreseeable future.

In the meantime, as the chargers will get busier we should encourage people not to use them to charge to 100% as routine or use them instead of home charging... its not a widespread issue now but it will become one and its better to have peoples mindset working the right way now rather than pinning it all on "loads of" FCP's being available in some future time.

OK ., but lets deal with a perceived problem in the future when it actually happens in the future ( if and when )

Time limits not related to the cost of electricity are easy to add with the current technology

FCP access could be limited by

total minutes per 24 hours
return time limits
onsite time limits

all of which have no bearing on charging

my own preference is a return time limit .

0-80% is still free again, promoting abuse.

Remember as car batteries grow 80% will take much longer to reach.

The 30 Kwh also charges a lot faster at 80% than the 24 Kwh.

Charging for the kWh is not ideal as well, as it will cost nothing when car is fully charged and wait there idle.

Have in mind that while at this moment it's not a problem, but if the network does not grow (and it will not) at some stage it is not the short supply of kWh, but shortage of charging points becomes an issue.

Maybe a combination of charge for kWh and time at charger would be better.

Very good point.

Regarding the Naas charger: I live in Naas and it's a terrible location for a FCP. It's off the motorway, on a road that gets extremely congested and it's at a shopping centre, which I suspect is the main reason people are often left waiting there. I don't think that people using it to charge rather than using their home chargers is an issue. I'd rather my car charge while I relax at home or sleep rather than drive to a Tesco simply to save a euro or so. I'd probably end up spending money on a coffee or something while I waited so I'd be worse off! What would be ideal there is a bank of 7kw chargers where you could plug in and go about your business.

I don't perceive that there's an issue with people "abusing" fast charge points currently. What is at issue is the reach and reliability of the network, and the fact that a few chargers were placed in less than ideal locations. None of this would be solved by charging the tiny amount of EV drivers that are on the road currently.

Very good point.

Remember we are talking about FCPs. Very few people want to stay in the Kentucky fried chicken to long


again you have to deal with the issue ,

today we have no issue,

in the future the issue is we made need more FCPs. thats whats we seek , not time based charging

if you want to deal with a specific issue, of someone leaving a car at an FCP, thats easily dealt with by special penalising " no charge " rates . i.e. you fill the car to 100%, you then get 5 minutes or a penal billing cycle kicks off. ( or you deny them access to that FCP for a period etc , whatever )

Equally the person just unplugs you and charges his or her car


none of these have anything to do with time based charging for the actual fuel itself, which is inherently unfair ( as is charging you to actually access the facility )


The FCP network is there to charge cars, its not the ecars job to control user behaviour . If we are finding in the future FCP spaces are scare, then we need more FCPS.

100% correct the decision to site FCPs at shopping centres is mind boggling wrong. they actually should be in some windswept hole on the side of major motorways and roads ( like those god forsaken motorway parking areas ) , people would move on fast them

100% agree about reach ( less of an issue from the midlands -east ), and absolutely about reliability , theres no way its justified charging for an network that has no real time information and where reliability is questionable

the fact remains , hogging at FCPs is not a general issue [/B] irish people are great at making problems out of basically non existent situations.

if and when hogging is an issue , then we need solutions, that would be handled by a gradual introduction of KWh unit based charging , preferably back through a retail electric provider so that retail competition can be introduced, with provisions for guest style access.

But ONLY when we have a critical uptake of EVs, otherwise we kill the market before it gets started.

BoatMad, you have the leaf a fraction of the time I have, I used the FCP at Naas daily for 9 months and ran into people using it for free electricity too many times to mention. And this is in several of my posts. And Newlands cross I also encountered this problem.

Also before you keep going on about me not caring about fast chargers or them being free or not just remember that I was requesting that the ESB charge for usage long before I even thought I was getting the work charge point. Or maybe it predated your appearance in the Boards.ie EV section.

So you might have used the cahrgers a lot (in the last few weeks) but you haven't yet used them a fraction of what I Have.

Also before you keep going on about the proposed EV charger usage charges are responsible for the drop in EV sales last November just remember that all car sales drop at the end of the year. And There are more Leafs sold so far this year than the same period last year.

You misunderstand, I would argue that I have visited far more chargers then you based on you comments that you dont do a lot of long distance f=driving in your leaf as your missus doesnt like waiting

On the other hand our Leaf is the primary long distance car. we dont use the pickup that much now.

I see no general issue, and we charge at FCPs virtually every day as well as charging every night

You may have an specific issue at Naas, but that issue is not prevalent elsewhere

Suggesting a solution merely as a method of solving you specific issue, is not a good way to create policy

Others have agree with me , that there is not a general FCP problem and my experience , in arguably a far greater number of FCPs then you , is that they are not busy at all

The Naas one is particularly stupidly sighted in a collection of supermarkets , this only encourages hogging .

charging merely to solve hogging is not a good policy

The anecdotal evidence and the nissan sales figures show that a significant number of decisions to buy Leafs in December ( when the 30 kw battery promotion was at its highest ) were then delayed as a result of the ESB decisions , and these decisions were only re-activated when the CER announcement was made

This was confirmed by Nissan at the recent IEVOA AGM too. the charge regime caused a significant loss of confidence in the economics of EVs


This was based on preorders for MY2016 30kw units by the way , not end of year sales shipped and billed by Dec 31

in fact to deal with the issue , Nissan held over the battery promotion cost until February to account for many people that delayed a decision based on the charges

it had a significant effect it seems

I would quite happily charge per kw at the same rate or slightly more than I pay at home.

I also haven't encountered the hoards of FCP abusers, but I have met 1. A local lady with an Outlander PHEV who until recently used to leave the car plugged in at the FCP and leave it for hours which meant anyone else had to sit there until she reached 100% or the charger automatically finished.

Very annoying, but another user I know from Facebook left a note on her window asking her to be more considerate and I haven't seen her there since.

I did however find myself 3rd in a queue there yesterday, which was a first. Ironically the 3 of us stood there talking about the selfish Outlander driver staying so long and hogging the charger, and then the guy ahead of me in the queue charged past 80% and I had to abandon ship, lol.

In his defence I think he just forgot, since the screen goes off after a while. He only popped out of the car when he realised I was leaving.
