Look into the fix. SOH seems a bit low. What temperatures are you driving in at the moment. Is that 240-260 km range made up of little journeys (when you would have to heat up the car each time or not?). In the UK at this time of year at those speeds that range is a bit on the low side. When I had it applied to my 50 earlier in the year, the SOH was down t o 89% and range reduced by 30 kms or so.

With CanZE, what's the kWhs when it is fully charged?

 

Checked CanZE today, 48,6kWh fully charged. What is "normal"? Is people seeing about 52kWh?

From what I understand, Tronity isn't given loads of information (especially from the Zoe), some of it is likely worked out by some maths. It's possible that Tronity knows distance travelled and start and end percentage, it thinks "oh, they've used 50%, so 26kWh, and gone 100 miles, therefore the consumption is 3.84mpkWh". (If I'm wrong on this information, please let me know and I'll amend).

I'd definitely trust the Car's own data, rather than Tronity's. I'd expect the Zoe's mpkWh to include lighting, heating use etc.

Ah okay, i was sure i heard somewhere that the Zoe doesnt count the energy that was used to heat the cabine, which will cause the "consumption" to be a bit off now during cold weather.

My dealer absolutely refused to even consider doing the BMS update or even the energy consumption screen update as it "isn't a fault"
They even claim to have fiixed the non-workng spare key after blaming me for putting a cheap battery in, but it still doesn't work and they have ignored my attempt to contact them.

I buried my wife yesterday and haven't had the time or energy to argue with sh*t dealers!!

I don't think I'll ever buy a Renault again.

Condolences on your loss, very sorry to hear about it..

 

Around 5c when i got a range of about 240-260km, also this was on one longer contiuos drive. Average speed of 78km/h, maximum of about 105km/h but only in eco mode. Will have the dealer make an appointment and check if its applicable.

Will check CanZe.

 

Probably nothing to do with the BMS, more the fact the heater is on.

What was your start and finish SOC?

 

I've had it done. If you do a search for 'BMS update' in the ZOE forum you'll find a lot of info.

My own notes below, including the ACTIS numbers (Renault references for dealers) and links to other forums reporting problems. Also info on the fix to get the Energy Info facility if not present on your car (although hardly worth the bother).

[For other readers: Of course, you can check the current firmware in your car using CanZE (you need a suitable OBDII dongle - see https://canze.fisch.lu/.]

ZE50: correct the SOH via an update of the BMS BMS

bug leading to an incorrect SOH: ACTIS: 64453. Applies if LBC1 is older than 540 (generally 521 for the vehicles concerned).

After update:

LBC: 521 -> 543

LBC2: 521 -> 540

EVC: 6A00 -> 69B0

BCB: 0A30 -> 0A40

https://www.goingelectric.de/forum/viewtopic.php?p=1478173#p1478173 .

ZE50: activate the Energy info menu and / or correct the displayed values

ACTIS 64756 application (or 64759 https://renault-zoe.forumpro.fr/t14975p75-menu-infos-vehicule#372353) to display the pages Energy Info.

In the process, ACTIS 64273 must also be applied to update the HEVC which is used to calculate the values.

Started at about 95-ish and reached my destination around 20-24. Calculated range was then around the figures i wrote, dont remember the exact numbers.

 

I have a feeling that 95% SOC is a bit less than that on the old BMS. So may throw off your calculation.

Was it wet outside?

 

Yes i have done quite alot fo reading about the subject. Will check the SW version in the afternoon!

 

A question regarding the reported consumption, is it what only the electric engines was using or the whole car?
For an example when the car reports 15,6kwh/100km tronity can report 19kwh/100km. Is it because the car only reports the engines consumption and tronity whole car?

Sorry for your loss.
As to the car, I found that the trick was to express "concern" over the battery SoH as it may cause me to invoke the battery warranty within the first year of owning the car.
My dealer quickly offered the BMS update then.

 

Condolences on your loss.
You hit the nail on the head about dealers... If you get a good Renault dealership you are laughing.. had loads of updates done to mine with no issues.
I must admit that I'm a pain in the @ss and always complain to customer services to make it official before I go to a dealership.
Renault London West and Renault Watford are good dealers down here and
DSG up in Morecambe.. is another brilliant one.

DSG are RZOC's official dealership.

 

48.6 kWh. It depends I'm afraid on the temperature of the battery on whether that is fine. It's not bad, that's for sure. When my battery was warm (around 25 Celsius) it would read 52 and a bit kWh fully charged. When it's cold (around 12ish Celsius) it might be around 50 kWh. Before the BMS update, 100% charged was in the 47s kWhs. If your battery temperature was warm when it was 48.6 kWhs fully charged then I think your SOH is a bit low.

 

Hmm okay.. Battery temp was around 9-10c. The dealer will said my VIN was one of the effected ones so they will hook it up and check what SW/BMS was in it and possibly update it.

Tbh i dont really know what to expect.. I was hoping to be able to make my 240km trip without major headache in mild weather. But as it looks now it might be a very close stretch even in full eco mode and limited speed to 103km/h. While some peope (this post--> ZE50 Battery SOH fix ) is making a 190mile trip with higher speeds..
Will report back tomorrow after i tried the trip, will precondition the car and i have it connected to charge atm to ensure 100% tomorrow morning.

 

Small update, did my trip today. Had the car hooked up and preconditioned when i left at 100%. No stereo, 19c inside car.
Temperature outside was around 2c, roads were dry.

Did exactly 230km, all in eco mode and arrived with 9% left, calculated range of 253km.
Consumption according to the dash 16,7kwh/100km.
If the consumption is right i should have a total battery capacity of 16,7x253=42,2kwh.

What am i missing? Where did the rest go 😅

Who cares? They are just numbers. You got there with a margin to spare.

 

I don't know for certain about the Zoe, but the Leaf has battery heating elements for colder climates. This might explain additional consumption when cold.

Certainly when driving the Tesla, cold weather below 14 degrees has a big impact on range. It would power limit if the battery was too cold as well.

 

After charging the car again i can say that the cars own reported consumption is highly incorrect, the Tronity app reports a way more likely consumption.
The trip this morning was reported as 19,7kWh/100km on Tronity and the car reported it as 16,7kWh/100km, slight diffrence there..
When recharging the car i quickly noticed that there was no chance that the car had consumed 16,7kWh/100km in average since i was charging alot more than what i would have had consumed..

On the return trip i averaged a consumption of about 22kWh/100km on 110km/h most of the way and a more normal 21c in the cabin, but also just 5-8c outside temperature..
Converted to miles i guess it would be about 2.84miles/kWh, winter tires fully inflated and most of the trip on cruise control.

I still wouldn’t take Tronity’s data as gospel, especially from a Zoe, as they supply so little data to Tronity.

For example, this is what Tronity reports a recent journey I made as:

I can tell you now that most of this data is incorrect (only things right are mileage, temperature and odometer) - it’s reporting I was getting about 10mpkWh at motorway speeds - which would be fantastic if true!

 

Can I ask a couple of things just quickly - I'm getting ready to book our ZE50 in to have these BMS and Energy screen updates done (under the guise of the fact that I have no list of maps appearing) and I want to know how to see what my current state of ECU firmwares is, as well as the SOH, so :-

1) How do I get CanZE to work with the ZE50 (I have a dongle which worked in the ZE40/22) if its any different to them ?
2) Where do the current firmware levels show up, is it just on canze, or does it appear in the car somewhere as well ?

sorry if these have been answered before, but this forum is getting so convoluted! We could do with some stickies to keep the latest bits of these info in and easy to find.

 

SOH you should find under just "battery". The software i have no idea unfortunately, hope that someone else can help with this.
The dongle i think should work.

 

Checked the software Today and my car had the old software. Have the car booked in for update on the 25th. Will report back if there is any change in range.

 

Rescheduled to 3/12 because of delay of some parts. Will report back after that!

 

So i had the BMS updated yesterday and they also updated the engine control unit, whatever it's called in an EV?

Suddenly the car now seems to be heating the battery when preconditioning is being used,it didn't do this before. Also the calculated consumption is also allt higher, but more likely it's now closer to the actual consumption rather imaginary numbers as before.

Went from 93,9%SOH to 95,9%. Car has done 5000miles.
