car should be in park not neutral
we can either be in a undervoltage state, or neutral
we’re also charging from solar
need to have a threshold for opening the solar relays
that threshold is not necessarily the overvoltage fault
cells are 95% charged
whenever solar closed, battery has to be closed
we should always make sure
motor controllers must not be connected
when car’s in parking, mci should disconnect
unless we’re not in an “undervoltage charge state” and we’re in “park” we should be able to charge
there needs to be continuous communication between BMS and the charger to taper the charging.
for MVP we keep it simple “two states”
once charging done:
tell evse by setting the switch
tell charger to stop
open the relay
shouldn’t go to neutral or drive again, unless we pull out the charger
After charging:
bms needs to send a taper message
bms needs to send a fully charged message
talk to liam
