A thermal management system and method of use are provided, the system including a heat exchanger, a refrigeration system, a coolant loop thermally coupled to the heat exchanger, and a by-pass valve that regulates the amount of coolant within the coolant loop that either passes through the heat exchanger or is diverted away from the heat exchanger. The coolant loop is thermally coupled to the battery pack of an electric vehicle.

Thermal management system with heat exchanger blending valve

An integrated drive system assembly is provided that combines an electric motor, a power inverter assembly and a gearbox into a single, multi-piece enclosure. Combining these components into a single enclosure reduces weight, reduces drive system complexity, reduces system volume, simplifies assembly integration into an electric vehicle, reduces manufacturing cost, allows the flexible and lengthy electrical cables between the power inverter and the electric motor to be replaced with short, low loss, rigid bus bars, and simplifies component cooling by allowing the use of a common thermal management system, i.e., a mutual thermal management system. The common thermal management system includes a liquid coolant loop that is thermally coupled to the electric motor, the power inverter assembly and the gearbox.

Thermal management system for use with an integrated motor assembly

A dual mode, thermal management system for use in a vehicle is provided. At a minimum, the system includes a first coolant loop in thermal communication with a battery system, a second coolant loop in thermal communication with at least one drive train component (e.g., electric motor, power electronics, inverter), a dual mode valve system that provides means for selecting between a first mode where the two coolant loops operate in parallel and a second mode where the two coolant loops operate in series, and a coolant reservoir that is coupled to both coolant loops when the two coolant loops are operating in series and only coupled to the drive train coolant loop when the two coolant loops are operating in parallel.
