if the Leaf is sitting still at a stop light - assuming that the climate control is OFF - in READY MODE, the only power consumption is being drawn from the lead acid battery (low voltage). the traction motor requires no high voltage current in the idle state. in other words, leaf sitting still...

2 big are HV + and - 2 little are low voltage main relay control all HV components are controlled by low voltage VCM the SDSW has a redundancy built into it - the little guys control the relays that control the big guys. no low voltage, main relays cannot close circuit and allow current to...
