This is a brilliant story of a ZOE repair by Dutch forum user “Jos Willems”. Here is the link to his post with pictures. You might need an account to access the pics and of course need to read Dutch or use something like Google translate, so I’ll give a short glossary here.

His Q210 stopped 3 phase charging which was a serious PIA as the home charger is 3 phase. Dealership stated the charger was toast and it “had probably taken with it several other components”, leaving the estimate in the 4.000 – 6.000 range, effectively rendering it a total loss. To add insult to injury the dealership offered 0 (zero) value if he were to buy a new car.

Not to be phased, he removed and disassembled the BCB (fairly easy on a Q model, but still “daring”) and found out it was not the dreaded welded relay contact. However the big triple filter cap assembly had seriously degraded; one cap was 5uF, which should be 100uF. After unsuccessfully trying to obtain the original OEM component, he decided to build a new capacitor bank from stock capacitors, if only to make sure this was the actual problem. Guess what? Car charges again as it should. He didn’t state labor time but my guess, excluding many frustrating phone calls was something like 8-12 hours. Component cost was 120 euro. Hats off!

I am usually staying away from criticizing the OEM. There are millions of cars on the road and s**t happens. Here though “the emperor has no clothes”: only because Jos was persistent, fairly knowledgeable and a bit daring he saved himself a ton of money and the environment a scrapped car. The cause was a the most simple component failing, misdiagnosed by the dealer and with basically zero support from said dealer and Renault itself.

By suggestion on the GitHub issue tracker by user dbwarrior1975, we added a simple but IMHO neat feature on the Voltage Heatmap screen. If a cell is being balanced the voltage is shown underlined. This is much more intuitive than the hex values on the Tech Charging screen.

However there is no clear known mapping between the bits in the balancing information and the cell numbers. Some help here would be appreciated. The indications may be horizontally or vertically mirrored, or possibly worse. Any feedback is appreciated. I expect the highest voltage (more red) cells to be balanced more.

As Google changed how permissions work in their apps, CanZE had to be updated in order to continue to work on more recent devices. This is why where has been a bunch of releases yesterday and one more this morning.

Symptoms are that the app crashes as soon as the settings page is being opened.

This is because actually CanZE needs the permission to view nearby devices, which a BT dongle is quite obviously 😉

If you want to help, please share any detail about this problem on the following issue:

SpeakEV user sr06 kindly send me this video. The mechanic is complaining about water/coolant ingress, but that is not why I am posting it. It gives a nice overview of the mechanical build-up of the Q motor. Especially the position sensor was new to me. Also the gearing is shown.
