ZS EV Mk2 51 kWh LFP battery - What is Your Voltage When Full?

[Peter WA]

402V

Amazing how close your cell voltages are 3.35 to 3.36V.

Interesting to see 99.9% SOC, not 100%, I wonder if your battery did properly balance after charging to full.

I can only wish mine was like that too...

It was reading 100% on the dash. I cut it short as the ambient temp was quite high and the fan had cut in. It usually puts up a message once balance charged. I have only DC charged once in just over a year from new and balance charged three times. Max separation any time I have checked has been 0.01v

When do you usually check this?

Reason I ask: When my car first ticks over to 100%, before (not actually) balancing, the highest cell voltage is 3.65V. Since yours is only 3.35V, something is different. Well, yours is better.

Although 3.35V, with no load, would be closer to 98% charged than 100%, just from experience with LFP cells in my home battery.

Did you use Car Scanner to get that screenshot, or a different app? Does it allow to read out the software versions of all ECUs?

I'd love to compare. My list looks like this right now:

Using car scanner. Don’t do a regular check due to not ever having much cell differential. 95+% charged off rooftop pv so < 4kW. Generally only charge to 80-90% to avoid overheating in Perth weather and to avoid diminishment of kers at 95%. Will try to interrogate software tomorrow.
