Electric car battery in winter: Heating, please!
The optimal starting temperature is between 20 and 30 degrees Celsius, said P3. As soon as a charging process starts, a battery cell heats up. If it is icy, for example, at zero degrees Celsius, it has a very high internal resistance, and much of the charging power escapes as heat, required to bring the cell to charging temperature.
