Battery heater

Wed Nov 08, 2017 12:17 pm

Does anyone know how to turn on the battery heater via CAN messages ? I would like to use it to heat up the battery since the winter is coming and the range will be limited as well as fast charging on the older 24kWh model.

The heater work with temp sensors.
When the temps are going to -20 celcius the BMS tell the VCM to activate the pack relay then the relay for heating have power on his contact to supply the heating pads.

VCM and the BMS work together on this.

I replaced my 2011 battery pack with a 2014 one who have the heater and I studied how it work.

Best is to buy heat pads for oil pan for gaz car.
You stick four pads of 100Watts or 6 of 50 watts and there is a 120vac automatic switch for this.
Just plug all together and plug in a 120 vac.

I remember one man done this and it work very well

Yes, but the diagnostic system supports active test for the battery heater, that means there is a way to turn it on via CAN.
