Heat pump system for vehicle and method of controlling the same

This invention describes a vehicle heat pump system that uses waste heat from the motor and electrical components to warm a liquid coolant. This warm coolant then transfers its heat to a refrigerant, which can be used for heating the vehicle's interior. The remaining claims specifically detail a method for controlling this heat exchange process during the heating mode.

Why it matters: Filed before the widespread adoption of electric vehicles. The focus on recovering waste heat from electric components and the method of controlling its use for heating is now critical for maximizing EV range and efficiency.
