Random EV thoughts.....

Old diesel

The main motors forum has the motors chat thread for the little things one would like to say but might not justify a thread.

Thought it might be an idea for here re hybrids and EV stuff.....

To kick off - i wonder if a new measurement for EVs might be assuming a start trip at 100 percent......

A how much range do you get with a 15 minute stop.

With a 350 kw charging a Porsche Tayman might do very well with getting on for 400 miles...

A Leaf 62 not so good.

Obviously where a car can do more then 50 kw charging we would need both a 50 kw and a whatever the cars top rate is figure*.

*IF chargers are available

What plugin hybrids are available. Only one I’m aware of really is the Mitsubishi Outlander.

Anyone know how long it takes an SEAI grant to come through when buying a new car? (The 5k grant) Is it any quicker than the 3 weeks quoted? Also how long after it’s approved would it take the garage to have a car ready to go?

There was some talk of all EV car grants on hold until budget was announced. Think I saw it mentioned by some purchasers on facebook. Also there is shortages of some cars like the Niro.

Thats for cars registered in 2020 AFAIK.
If they have an EV ready to be registered in 2019 they can go ahead and register it and claim the grant.

oh, so the paying for charging for now is only for the 'fast' chargers.
I presume the Type-2 AC Socket 22kW charging stations are NOT considered as fast?

Correct

Lumen

Taycan charge curve at Ionity, from 5:51

Charge to 80%: 20 minutes
80%-100%: 30 minutes.

11%: 250kW
22%: 260kW
34%: 200kW
39%: 150kW
60%: 155kW
70%: 160kW
71%: 150kW
75%: 120kW
80%: 90kW
85%: 38kW

Then seems all over the place until 99%.

Forgive my ignorance but at 800v why does it not charge much faster that that?
We've seen the model 3 charge at 250kW on 400v and 200kW on 400v at Ionity. For me, incredible as it seems, those charge rates are too slow for what 800v could be.

You'd certainly think that it could keep over 200 kw for longer .

Personally I suspect Porsche want to ensure durability and consistant charge speeds during both individual long trips and over the long term into higher mileages.

They would want to avoid scenarios where.

1) you get 350 kw charging at 1st rapid but the car only does 70 kw at 2nd stop.

And

2) avoid Tesla type having to cut back charge speed when car is older .

We could see more power being allowed charging wise if Porsche are happy with data from real world .

Lumen

I don't think anyone outside the industry really understands why the fast charging profiles differ so much between different manufacturers and models. There's a lot of speculation (voltage, cooling etc) but few verifiable facts.

Ultimately I doubt the decision on whether someone buys a Taycan or a top-end Model S is going to come down to how many kW it takes in the top half of the SoC. They'll be chosen mainly for emotional and aesthetic reasons, just like most cars always have, cheap or expensive.

Their headline figure a few years back was 350kW but then they said in the last year or so that the max it would do for the first version of it would be 250kW and then they would look at 350kW after that.

My guess is the pack they have isnt up to a 350kW rate and maybe they are waiting for a different pack in 2022 or something. Could also be a case of being conservative and waiting for some telemetry data back from production cars and maybe they'll unleash the power OTA later once they see the packs are holding up.

250kW is serious power all the same, although it did drop back to 150kW rather quickly

Lumen

Charging speed can be spun many ways.

For example, while the "0-80% in 20 mins" of the Taycan seems impressive, that's only about 330km WLTP, which is 56% of a Model S Raven (I think), or 52kWh. So to match the Taycan in terms of "km per 20 min of charging" only requires 156kW average, which isn't that much of a challenge.

Efficiency matters.

Are you sure?

I've seen a lot of terminology referring to these as fast chargers, as opposed to the rapid chargers - CCS / CHAdeMo / Fast AC?

Some call the DC chargers "Rapid", and the 22kW AC chargers as "Fast". Some (or most in my experience) call the DC chargers "Fast", and the AC chargers "slow". IMO, they're slow. Taking 3-4 hours to charge my car is not fast.

Car is nagging me for a service

Do I bother with a main dealer eye gouging me or not?

I can do the usuals myself but I'm wondering what a dealer can do that would be worth the stretch?

Is it still under warranty? If so, go dealer.
Your call otherwise.

Yea, still under warranty

Do you get any decent feedback on the battery health / hi voltage components with these inspections?

Looks more like €120 I should keep in my pocket

Hydrogen cars will never happen. Surely that was clear for all to see at least 5 years ago? The only future for hydrogen that I can see is that we can produce it with excess renewable energy to be used to generate electricity at peak demand time, or for powering ships or other incredibly power hungry machines

Never seen a more crooked shower of companies involved

BOC Gases, Bord Gáis Energy, Toyota Ireland, CIÉ Group, Hyundai Ireland

Who would even want to go near that group

ELM327

All of whom have inherent bias

I dont see alot wrong with the article in the context of what they are targeting...

...confirmed that it will initially be aimed at “captive” fleets, whereby vehicles can be refuelled at a central depot. “It’s a central hub model, for now, rather than a distributed network. Our focus is on captive fleets, and Dublin Bus and CIÉ as a whole are both part of the group, and contributing to the discussions.

Hydrogen starts to make sense for captive commercial fleets.

The grid is supposed to be going towards a much higher percentage of renewables which means there could, in time, be excess energy available which you can then use to generate hydrogen.

Certainly a hydrogen fueled Dublin bus is going to be better than what we have right now. Its really down to how the hydrogen is generated as to whether its worth doing or not.

For cars, cant see hydrogen working. The cost of putting hydrogen stations all over the country is prohibitive. They quoted €2m per station.... that aint going to happen by 2030!

China has about 500,000 BEV buses (and growing very quickly) and about 1,000 hydrogen buses, the latter mostly trials promoted by some heavily invested stakeholders like Toyota

Buses need to go BEV, all R&D into hydrogen for road transport is a complete waste of money

Hydrogen fuelled back up electricity power plants (for when a jurisdiction is low on renewables and low on interconnector import), that is the main future of hydrogen
