On a separate issue raised by your usage, it is frequently stated that a 100% charge should be occasionally be performed to balance the battery cells. So what does Spy show about the balance (or otherwise) of yours? What is the difference between the highest and lowest cell voltage? It would be valuable to know whether the way you operate your battery is bad for cell balance, or otherwise.
I'm happy to update periodically. So far with one year and over 20k km of use, the numbers I'm getting via SoulEV Spy suggest it doesn't need a balancing charge yet. Despite a year of use, it's never once been charged to 100%. Only on two occasions has it been charged to 90%. A few occasions for 80% (once to 85%), and several occasions to 70%. But the overwhelming number of times, it's charged to only 60%. It has only once ever been DC charged, and that was just about a half hour, and not up to a particularly high charge level. The car is also consistently driven very conservatively, so the battery pack is rarely being drained especially quickly.
TLDR; it's AC charged, usually only to 60% (and never to 100%), and driven conservatively.
After charging to 90%, and then letting it sit for 90 minutes, the display then read 92%. I noticed one other instance of it being charged to 50%, and then after 90+ minutes of settling the display read 55% (it had been unusually low, like 32% or so, before commencing that charge I think). I've seen this on my e-bike as well, and I think it's a natural process of the cells providing a more accurate reading after some settling/cooling down. An effort is made to let the car sit for 90+ minutes before every recharge, to allow for the cells to cool/settle and give more accurate BMS readings before charging starts.
Anyway, after that charge to 90% and letting everything cool/settle, every single cell in the pack had the exact same voltage. 4.06v I think? I didn't write it down, but it was black across the board (the grid is colour-coded with cells that are higher one colour, and cells that are lower another colour, but every single one was black indicating no variation across the board, meaning any variation was so minor that it was effectively hidden by them all rounding off to the same number). So I take that to mean that even a year of conservative charging and driving wasn't enough to require a rebalancing charge.
