This is Baran Celikten from Ford OTOSAN BMS team.
We are using SK32K144EVB and FRDM33771BSPIEVB cards to develop BMS algorithms. We have some modes which includes sleep or even off mode ( when supply voltage is lower than a threshold). At this point, when BMS is off or sleep, we need to time clocking. Is it possible for this cards even if supply voltage is not enough. Or in other words, Is voltage sensing enough for RTC feature and store clock to use when BMS is on.
