Abstract
A heater system for an electric vehicle that is void of engine coolant. The heater system can include an air duct having an opening into a passenger compartment of the vehicle and a heater unit attached to the air duct. The heater unit can have a self-contained quantity of oil within an oil reservoir and an oil channel in fluid communication with the oil reservoir. The oil channel can be located between a front wall and a back wall of the heater unit and the unit can also have an electric heating element at least partially within the oil reservoir. The electric heater unit can be operable to heat oil in the oil reservoir and thereby result in the oil flowing through the oil channel and heating the front wall and the back wall of the unit.
