Both HV and 12V batteries can't become completely discharged when the ignition is on. The HV battery will keep the 12V circuitry energized, and the ICE will charge the HV battery.
The weather turned warm, and my EV mileage increased.
Yesterday 38.1m, 99.9 indicated MPGe, 14% remaining battery. The full charge was 11kwh. Calclated 117MPGe
Today I drove 41 m, 93 indicated MPGe, 6% remaining battery. the full charge was 11.9kwh. Calculated 116MPGe.
I need to see how much the full 0-100% charge will be in the warmer weather. In theory, the battery capacity should go up.
