ELECTRIC VEHICLE HEATING DISTRIBUTION SYSTEM AND METHOD

摘要

A heating system for an electric vehicle includes a heat pump subsystem, an electric heater subsystem, and a controller. The heating system further includes one or more sensors for determining an ambient temperature value and a heat pump operational efficiency metric value and for providing those values to the controller. The controller is configured to determine an optimal heating contribution percentage of the heat pump subsystem and the electric heater subsystem from the determined ambient temperature value and the determined heat pump operational efficiency metric value. The heat pump operational efficiency metric may be a compressor discharge pressure value. A related method is described for determining an optimal heating contribution percentage of the heat pump subsystem and the electric heater subsystem.
