OVMS heating

This site may earn commission on affiliate links.
I just checked my OVMS and on the battery page it says "heating" instead of "charging" which I've never seen before. It is cold outside (21 F) but the garage is showing 31 F . Any need for concern?

No need to be concerned. "Heating" means preheating the battery before actual charging starts. Runs at about 8 amps. It is a normal function of the Roadster and you will see it reported on the VDS too. It is not anything special that the OVMS does, it is just reporting it.
