I tested 15 min drive in the city with max 50kmh roads and logged the lowest battery cell temperature starting at 3°C and finished at 3.5°C. I used OBD car scanner on Android. No preheat engaged in this test, next time I should activate the pre heat, good to know how fast it will increase the...

I have now confirmed that the BMS lets the battery charge in below zero temperature. There is no wait for the battery to heat up before charging. I can charge at 10kW when the battery temp is -4°C and the heater will start at the same time the charging starts. If the heater draws 4kW then the...

i have connected a odb dongle and tested the heater from in car, with the battery temp at -0.5c the heater draw around 10amp (info display at 0 before start) and 10 amp at 394v is around 3,9kw and in the service manual from a pre facelift it is spec at 3.5kw but will increase some when the water...

yes the BMS should... But i have not seen any indication in the power logs when charging in way below sub zero temperatures, when i have charge at 10kw the charger directly starts at 10kw and i doubt the heater draw that much, so some amps will go to the battery. Tonight the settings in the...
