on my zoe, pressing the plug release button on the car shuts down charging gracefully

given latching the plug is part of the type 2 standard, this should be common to all cars that take a type 2 plug

The earliest Zoes are around %80 at 7 years old (the 22kwh ones)
given they were the same chemisty as the leaf, it shows how much a difference thermal management makes

there might be a motor insulation element to it too - higher dc bus voltage means a higher dv/dt, which is harder on insulation

no issues, would just put out less heat

their resistance changes with temp, so it probably won't be as much less as you might expect (ie 1/4 voltage would be 1/16 power if fixed resistance, but more likely would be only 1/4 power due to resistance also dropping)

Nope, just a zoe thing.

But to know for certain you'd have to measure different charge rates on each car

I was warned of battery problems if only charging at 10A regularly (and the manual https://ie.e-guide.renault.com/sites/default/files/pdfs/eng/X10/ZOE-979-14_ENG.pdf explicitly says it's for occasional use only). Yeah, there's no battery problems resulting from charging at 10A. It's more marketing ...

even 10A requires a good quality extension lead - minimum 1.5mm2 conductor size

being able to plug in just about anywhere is great though

sadly, the type 2 lead isn't an extension, the pins are purposely recessed so it can only be plugged into a charge station

Not all CCS2 stations will actually supply AC to the plug - CCS2 is generally only used on DC charge stations, which the Zoe can't use

ZE Ready is more of a marketing term - the zoe is compatible with all type 2 evse for one in australia: https://evse.com.au/product/15-amp-portable-type-2-ev-charger-bmw-hyundai-renault-tesla/ this is what I use: https://www.aliexpress.com/item/32810465697.html?spm=a2g0o.productlist.0.0.48976c1cT70F...

I have an Orion BMS in my shed if you're interested

Whot you mean about battery Molicel INR-21700-P42A? Maximum charge is 8.4A. With use 15pcs. We have max charge 126A. This is enought for DC-DC charging (max. 125A) https://www.imrbatteries.com/content/molicel_p42a.pdf In europe cost 1pcs 4.3€. One LEV50 = 65€. All pack 5720€. that's a lot of weldin...

Jsvader - are your kwh/100km figures quoted by the car? or are you measuring on recharge (AC pulled from the wall)?

The later is generally used for comparing EV efficiency, as it includes all the round trip losses

I'm connecting the original prius BMS to every 5th LiFePO4 cell, which should have the same voltage range. I think partly what did my first attempt in, was I was continuously updating the SOC in the BCU to 100%, so it didn't stop discharging in time. Doing this new setup with the shunt divider was t...

Good idea

oh, so you're doing similar to me, replacing the original battery with a lithium one sadly my one uses an obscure communication language called OBD-M or multiplexed OBD, so man in the middle adjustments for me my main issue is how to the car from over charging, or overdischarging individual cells. T...

oh, that's the other thing - the zoe can stay at 32A all the way up to max voltage (not sure how high it cuts out, but I've been above 260v) actual chargers tend to be power limited no pf correction is more of a compromise rather than absent completely, but is more of an issue at low charge rates (1...

The gen 2 would probably do better, does yours have the ev button?

I still haven't got it going, too many other projects sadly.

Tbh, I don't think it will do any better than the last one I built in terms of energy efficiency. And the rego is nearly due.

High line voltage? At 255v 32A I could see 8kw happening (pf isn't corrected on the zoe)

Rear sensors are great. I had never heard of front parking sensors until today. Brings whole new meaning to drive by sonar

Great outcome. Good call Smithy

Put some moisture absorbing material in there for good measure?

Not a minicab but I do have a 2012 imiev ( or rather I bought it new then sold it to my dad who currently owns it) Of course there's no guarantee as to commonality between the two vehicles 🙁 Can you post a picture of the charge cable that came with the car? My imiev works with a duosida charge cable...

it would be worth (getting a qualified person) to open up the original type 1 cable and see if it can take 220vac (it will be a matter of whether it's internal power supply can take the voltage)

it may be a timing issue, do you have other charge cables you could try?

is it a new leaf? or the older gen 1 leaf?
