Well, everyone who's reviewed it so far, plus Renault's own website. They've always quoted usable figures on their public information, never the gross capacity. So they're claiming 52kWh.

Yes, however in the detailed reviews they’ve explained the difference between total and usable capacity.

No great mystery.

Apparently fuel tanks have the same feature.

The Renault literature refers to 22kWh, 41kWh and 52kWh. It states in the Renault documentation that it's 52kWh usable:

The label on the door, to me, seems to be an after-thought, and I usually trust a bit more the label on the battery. This is what is confusing, that the battery label states 50kWh, but a door sticker and the Renault papers state 52kWh usable.

The great mystery is that the total (what's written on the battery itself) is lower than what's quoted as usable. Unless the definition of the words or physics have changed in the mean time, usable should be lower than total, not the other way around.

Sorry, I can’t see the part where it states 52 kWh usable?

Thought of an actual question!

Does the rear demister activate on a pre-heat? That's one mild bugbear in the ZE20, you stand there with a cuppa in the warm watching it mostly defrost, then go get in the car, start up, turn the rear heater on and sit waiting for a further 2 minutes while that thaws out. Not the end of the world but a good opportunity for improvement.

Mind, it managed without this morning when the car went into the "yikes it's -3" level of heating so maybe it's not that much of an issue. Sometimes it does sometimes it doesn't.

Interesting. Well there’s only one way to find out for sure.

 

[yoh-there]

1. OBD connector is just forward of the handle to open the bonnet (on a LHD).
2. CanZE does nothing indeed. Actually the "free frame" chatter as it exists on the older models in non-existent.
3. MM bus is no longer on the OBD connector.
4. CANbus speed is still 500 kbps, but it seems a command is needed to "start" communication.
5. An expensive "universal" car diagnostic tool managed to get nothing more than the VIN and that was it.

If anyone spots really recent ddt2000 definitions, please let met know. I still have a few ideas but this won't be a quick one.

 

[Mo1]

@yoh-there Thanks for looking into that, much appreciated by myself and many others I'm sure, canze has been invaluable hope you can eventually crack it for the ZE50

It’s 52 kWh capacity with 50 kWh usable capacity. Fairly normal.

Except all the info provided so far has suggested 52kWh usable..

The Renault literature refers to 22kWh, 41kWh and 52kWh. It states in the Renault documentation that it's 52kWh usable:

I find all this "banter" quite interesting. While I agree the 22kWh model had 22kWh usable, reports on here tend to show 39kWh is the max anyone seems to use (great CANZE shows 41 but its what you can actually use that's important). TeslaBjorn didn't seem to manage to account for more than 48kWh on either of his tests. So what does the ZE50 actually have as usable?

 

[Spike]

I'd be willing to have a play in one to find out

Ah you say that now, but no one seems brave enough to test their car too grinding to a halt (intentionally) and maintaining the wherewithal to take pictures of the resulting screens in car and in CanZE.

I cannot see myself upgrading to the new zoe.
poor AC, only 50KW charging DC, Poor radio, Renault aftersale service is very poor in Ireland. For 30k euros, plus, One can have a much better car.

Which equivalent car were you thinking of?

Presumably sticking with their older Zoe?

True this is the actual vs usable debate.. but for actual this is definitely 52 kWh:

The bottom line: with an operating range of up to 395 kilometres according to the WLTP* protocol and a capacity of 52 kWh, the New ZOE provides one of the best ratios of stored energy available to distance travelledon the market market.

Z.E. 50: the secrets of the new ZOE’s battery - Easy Electric Life

The Z.E. 50 battery that powers the new ZOE gives it a range of up to 395 kilometres according to the WLTP* protocol. That’s a 25% increase in range compared to the previous generation.

and

For example, the New ZOE’s Z.E. 50 battery is made up of 192 cells and offers a 52 kWh capacity, for a range of 395 km (by WLTP* standards).

52 kWh useable according to this Renault doc (page 89) http://fr.zone-secure.net/-/Renault/Presskit_Renault_ZOE/-/publication/contents/templates/New_ZOE.pdf

hey, sorry for delay, I am thinking: prius plug in, or a Nissan Leaf 40kwh. or else a Niro.

 

[paulBzoe]

My ZE40 does not use the rear demister when pre heating. I find the pre heat this week brilliant. but at minus 3, my battery did not like it at all. As soon as I get in , I drive off, and then stick heater on AUTO 21 deg, and rear demister on. I find in eco mode, the rear window and mirrors, demister last only a minute or two.

I'm not disputing what Renault is claiming is usable. I'm just saying TeslaBjorn tried twice and both times couldn't use it all. Calculated 48kWh was the max he could extract. Now this is much like the 41 where most seem unable to use more than 39kWh when push comes to shove.

@paulBzoe

I think the rear window demister turns off after 10 minutes even in normal mode. I use it to defrost the mirrors as that seems to be the only time you can activate the heated mirrors.
