Zusammenfassung:A method of detecting and mitigating icing of an outside heat exchanger in an electric vehicle including a heat pump. Various sources of heat may be utilized to de-ice an outside heat exchanger of the heat pump. The sources of heat may include one or more of vehicle electronics, a high voltage ("HV") battery, and an HV coolant heater. Pre-defined criteria may be utilized to determine the actions to be taken to de-ice the outside heat exchanger and/or to prevent icing of the outside heat exchanger.
