[Ovmsdev] 3.2.011 BUG for MIEV based cars

[Tamás Kovács]

Please create a log file while you charging with 230V (1-2 minutes enough),
start logging before connect charger and send it to me.

   - can log crtd /sd/file.crtd 286
   - …record…
   - can log stop

The Ideal range is based on 16.1kWh/100km consumption and the battery
health (this updated during charge, quick and normal charge). My car is
2012 Peugoet iOn, with SOH 78%, and my RR at 100% is 113km, the old code
calc the RR during quickcharge with last rr 20 and range 8km if soc < 20
this is too optimistic i think.
Ideal range calculation is = cell_number * 3.7 * bat_cac * bat_soc /
16100.  So my full charge ideal range is ~75km.

In your car the bms cell monitor working?
