This way you can save fuel with a parking heater in your car | in the path

It is also possible to modify the parking heater with electric cars. This is an electrical system that draws its energy from car batteries. However, many electric vehicles come standard with a heat pump. To increase energy efficiency, the battery pack with this heat pump can already be preheated. This also applies to the interior. By turning on the heat pump when the vehicle is at the charging station, you are extracting as little energy as possible from the battery pack during a “cold” start.
