Why? The range will just keep going down. Even if it is down to 35km, it would be perfectly fine for someone with a 10km each way commute, school drop car, OAP local car, etc.

And the car would be worth less than a replacement pack

EV battery replacements are simply not going to happen (unless under warranty). Refurbishments by indy specialists, that will happen at a fraction of the price of a pack supplied and installed by the main $tealer

Even DIY. I saw a clip of the replacement of the battery pack with a refurbished one in a Toyota Prius hybrid. I would take that job on myself, and I am far from handy. Take old pack out, send it to the refurb crowd and get a refurbed pack all for about €500-€700 + shipping costs.

I think I saw the same one. I'm about as good on the spanners as Jeremy Clarkson but I reckon I could take that on quite easily. If the leaf is the same then I reckon it should be a pretty simple DIY job if you got a replacement pack and had a transmission jack and a lift, to deal with the pack weight

Just half way though the video (he has a really funny Ukrainian accent). Anyway, he installed new LG Chem cells into the old battery module achieving the same weight. 44kWh net capacity with gross capacity of ab 50kWh - bigger than in 40kWh leaf. Estimated range was ab 400km at speeds 55-60kph. At 10min he started telling the history of the car - it was bought at 4years old with 90000+km and SOH of 42%. Apparently there was a defective charging module and the car was exclusively charged on CHAdeMO (x1800). There was only ab 80 L1/L2 charges which he thinks were done at the factory. When he opened the module he found that bus bars were not fixed properly as 2 screws were missing. The module was factory sealed so it def was a manufacturing defect. Adding the screws has fixed the problem.
By the time GOM showed 21% (28% leaf spy) he covered 300km at cruising speed of 60kmh. He also mentioned that he deflated tyres a bit to improve the efficiency (2.2 at the back an 2.5 at the front) and was free wheeling downhill (in neutral) - 10.6km/kWh. GOM 8% (15% leaf spy) - 360km, 396km at 10% leaf spy. At SOC 1.8% he was at 446km at which point he decided to start charging.a
At first he started charging at a 125A (42kW) and charged ab 12-15kWh in ab 20min. The battery temp raised quickly from 28C to 36C so in order to reduce the temperature (he wanted to drive back at 90kph) he moved to a 40A charging station. He charged 20+kWh after 1h20min (batt temp 39C, outdoor temp 26C). So in total after 2h of charging (not to10p% though, was too long and boring to wait) the bat temp was 40C, he was saying that it’s not critical (2 bars away from red temp zone) but he would prefer the temp to be lower. After driving 80-90kph for 8 min the temp dropped to 39C and was keep on dropping. Charging is primary source of generation heat in the battery and excessive rapid charging will damage the battery. The consumption under 100kph was 7.3km/kWh.
So to finalise - build time is ab 1month, 50kWh charging capacity, 44kWh usable, average range is ab 350km in eco mode, town - up to 450km, at 100kph 280-300km.

It's always been my understanding that higher tyre pressures increase efficiency. Lower tyre pressures would surely increase rolling resistance.

He said that he had better consumption with deflated tyres. Go figure!

Bit of an eye opener on John cadogans channel on you tube about some leaf issues regarding battery.

Could be a bit more helpful here in some sort of a summary of the issues.
First we have to go look for You tube
the the bloke
then the actual article.

Some guy got quoted $33k AUD for battery replacement for his 2012 gen1 LEAF with gen1 crap battery chemistry to upgrade to the latest 24 kWh battery.

A battery replacement is not something that is an issue on any other BEV than 11'-131' LEAF and 12' Renault Fluence. And the new official price for the battery turns out to be $9.9k AUD + labour so it's all a misinformed BS story to start with. John Cadogan just comes across as an angry old man tbh.

Bottomline, a gen 1 Leaf in a hot climate is a very bad idea. That has been well known since at least 2013 where they were failing in numbers in Arizona.

samih · 08-10-2019 2:44pm

I guess it's another example of the generic perception of the EV=milk float, let's all laugh at them changing to EV=potential threat to your old views. And then finding data that shows all the idiot EV drivers how wrong they were buying a Nissan LEAF sh1tb0x (as John so eloquently calls them).

Anyone know anything about the Chargers in the Luas Park & Ride at the Red Cow? I was there a few months ago and they weren't working, and they aren't on the eCars app either? Would be handy to use them tomorrow...

That's a shame. Thanks for the reply...

A quick etiquette question... I was at a fast Charger today, arrived just behind someone else who plugged into the Chademo, which I needed. They had a 191 Leaf.

An hour later they were still charging. I asked them if they were going to be much longer and they said another 5 minutes as they needed to fill their charge to get to Sligo (from Johnstown Bridge).

I've always thought that with the fast chargers you use them for 20-30 mins top ups, and if I have a long journey I'd plan a couple of stops rather than one long stop. So I was a little annoyed to have to wait an hour so I could top mine up for 20 mins! Is using a fast charger for an hour ok, from an etiquette point of view?

Thanks...

Most of fast chargers in Ireland can supply only 50kW which would translate to 25kWh per half hour which is less than half battery for many vehicles. Additionally some cars would have lower battery voltage and they would not even be able to use those chargers at their maximum speed.

They can do what they want right now in reality, Sligo is a bit of a black spot so they may have needed the juice.

It will not be long until paid for charging comes in and hopefully its per minute which will speed up the current process quite a bit as charge speed tails off and value for money drops.

jasonb · 13-10-2019 1:18pm

Yeah, I suppose as range gets longer then so does the ‘top-up’ times. But while Sligo might be a black spot, there are 3 other fast chargers on the road between Johnstown Bridge and Sligo.

I don’t know, maybe I’m being naive or unrealistic, but I think if I knew I was going to be using a Fast Charger for an hour, and someone was waiting to use it, I’d at least let them know and ask the how much of a charge they needed. I only needed 15 mins myself, but had to wait an hour to get it.

I’m glad it’s fairly rare that I’m relying on public chargers.

slave1 · 13-10-2019 1:47pm

Given the dependability of the network it's hard to criticise someone for charging right up once they get juicing off a working charger.
I went to public charge for maybe the second/third time this year at a 22 point and it said working and hook up but the flap would not drop to expose the connection, on the way home we passed by the rapid and said to herself sure lets give it a rapid (as I've heard it's good for battery every now and then) but alas it's broke also.
Total joke, and they want to start charging for this mess:rolleyes:

NIMAN · 13-10-2019 8:36pm

The public system is a joke.
My one locally charger has been faulty for approx 6 months now, and it's been reported a few times, so they obviously have no interest in fixing it.

Hi

Has anyone any experience/recommendations regarding the use of portable (cigarette lighter charged) heaters/de-misters.

Something like https://www.amazon.co.uk/Tenlso-Defroster-Windshield-Cigarette-180-dgree/dp/B07XP65ZJW/ref=sr_1_1_sspa?crid=1KPEPOZ5P8SPD&keywords=portable%2Bcar%2Bheater%2Bdemister&qid=1571648012&sprefix=portable%2Bdemister%2Caps%2C123&sr=8-1-spons&spLa=ZW5jcnlwdGVkUXVhbGlmaWVyPUEzMENaVzNNM0szUks0JmVuY3J5cHRlZElkPUEwODE4ODQ0MVFXOVZMVkVXWEszMSZlbmNyeXB0ZWRBZElkPUEwMDU3NzQzWDNTS0tWSDhSMzlRJndpZGdldE5hbWU9c3BfYXRmJmFjdGlvbj1jbGlja1JlZGlyZWN0JmRvTm90TG9nQ2xpY2s9dHJ1ZQ&th=1

I have a gen 1 Leaf and in the morning I can pre-heat. However, for the trip home I can't pre-heat and the car takes a lot of time/power to heat up.

As such I was wondering if the portable heater option might work.

Any feedback would be welcomed. Thanks.

zilog_jones · 21-10-2019 10:25am

And you think a 150W device won't take a lot of power? The cigarette lighter socket is only rated for 120W IIRC.

If the front demist mode on your climate control is not clearing the windscreen quickly then something's probably wrong, either blocked cabin filter, aircon or something else.

Regarding the power, I read in some of these forums that the Gen1 leaf heats a large amount of water as part of the heating. i.e. I thought that direct heat would be more efficient.

Thanks for the heads up on the 120W rating. Cheers.

rodneytrotter15 · 21-10-2019 11:08am

Can anyone tell what's the correct app to install so that I can check on charging status or override the timer and tell the car to start charging or pre condition etc ? Assuming this is possible on a 2016 Leaf. I see a Nissan EV app, a Nissan Connect app and an EVA app that seems to use Nissan logon details

NissanConnect EV

EVA is a 3rd party app that no longer works but was better than Nissans app, imo.

Do you have an early model with no heat pump? The (air source) heat pump is very efficient if you have one. Otherwise it's resistive heating (just like a toaster) - either way there's no water involved AFAIK.

Yes, it's the early model without the heat pump.

Seems to be very inefficient.

Here's an image of the heater in action. Yes, that's approx 4.5kW in use! That's with heating set to max whilst driving this lunchtime.

The 2011-131 uses a conventional coolant to heater matrix system. The 132-> version especially when equipped with heatpump is much more frugal on short trips but even the resistive heater is more energy efficient on them.

How long does it draw that 4.5 kW when starting with a cold car without preheating? Would be interesting to see what the impact is.

If I remember it right on the Gen 1.5 with heatpump the 3 kW+ phase normally lasts a couple of minutes on a cold morning before the heatpump kicks in and that only draws about 200-300 Watts and cycles on and off when the heating is set at 19 degrees. Hot air is felt within about 20-30 seconds.

I'll do an experiment this evening on the way home and I'll report back. Cheers.
