An electrified vehicle and method for heating a passenger cabin of an electrified vehicle that may include an internal combustion engine in addition to an electric machine and a traction battery for supplying the electric machine control an electric heating element to store thermal energy while the vehicle is connected to an external power source that is also used to charge the traction battery, and to extract stored thermal energy during operation of the vehicle with the electric heating element turned off to extend the electric driving range of the vehicle while also providing heat to the passenger cabin. The electric heating element may positioned and controlled to heat one or more elements directly by mechanical contact, or indirectly by heating a circulating liquid coolant to a temperature above a current or anticipated external ambient temperature.

Plug-in electric vehicle and method for heating a passenger cabin

A vehicle includes an oil-cooling system arranged to circulate oil through an electric machine and an oil-to-coolant heat exchanger. A coolant system has conduit arranged to circulate coolant through an inverter, a heater core, and the heat exchanger. A climate control system is arranged to circulate an airstream through the heater core to heat a passenger cabin with waste heat from the electric machine and the inverter.

System and method for heating passenger cabin with combination of power electronics and electric machine waste heat

An example cooling system for an electric includes an electric motor having a supply opening for receiving coolant and a discharge opening for expelling coolant. The discharge opening is connected to the supply opening via a coolant circuit including a first return line in which a heat exchanger is arranged, a bypass line, and a second return line. The discharge opening is connected to the supply opening by both the first return line and the bypass line, and the bypass line bypasses the heat exchanger arranged in the first return line. A battery is arranged in the second return line, and the second return line is selectively connected to a short-circuit line which causes coolant to flow from a point downstream of the battery and return to the second return line upstream of the battery. Further, a heat accumulator is arranged in the short-circuit line.

Electric motor with cooling system and corresponding method

An operating method for an electrified motor vehicle having an electric drive while being coupled to a towing vehicle by a connecting device in such a manner that the pulling forces and pushing forces between the vehicles are transmitted. The towing vehicle may communicate data to the motor vehicle used to control the motor vehicle to provide a controlled force exerted on the towing vehicle by the motor vehicle during towing. The controlled force exerted on the towing vehicle may vary based on the prevailing force direction between the vehicles, acceleration, and battery state of charge (SOC) of the motor vehicle. The controlled force may include a driving force or a braking force. The braking force may be provided by regenerative braking of the motor vehicle and/or by friction braking of the motor vehicle.
