With internal-combustion vehicles, cabin heat is provided by the production of calories from the engine. So how to heat an electric vehicle? The answer lies in the heat pump, which produces hot air using a condenser built into the air conditioning unit.

Or how to optimize ZOE’s range


The heat pump

The heat pump fitted on ZOE is a reversible air conditioning system. In heating mode, it works like an air conditioner, but in an inverse fashion. When changing from gaseous to liquid state, the refrigerant gives off heat that is used to warm the cabin. The fluid evaporates at the front end of the vehicle, while the condensation process takes place in the air conditioning/heating unit in the interior.

The heat pump uses half of the electricity used by a conventional heating system. Depending on vehicle use, it increase vehicle range by a full 25%.
