Abstract
An external heat exchanger of a heat pump air-conditioner on an electric vehicle is determined as being frosted based on signals from temperature sensors. If the external heat exchanger is frosted, then a frosting flag is set and the air-conditioner is operated in a cooling mode to radiate heat from the external heat exchanger for thereby defrosting the external heat exchanger while the air-conditioner is in a pre-air-conditioning mode before the driver enters the electric vehicle or while the battery on the electric vehicle is being charged. While the battery is being charged, the external heat exchanger is defrosted by the electric energy supplied from an external power supply to charge the battery.
