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 thermal management system is provided that minimizes the effects of thermal runaway within a battery pack. The system is comprised of a sealed battery pack enclosure configured to hold a plurality of batteries, where the battery pack enclosure is divided into a plurality of sealed battery pack compartments. The system also includes a plurality of battery venting assemblies, where at least one battery venting assembly is integrated into each of the sealed battery pack compartments, and where each of the battery venting assemblies includes an exhaust port integrated into an outer wall of the battery pack compartment and a valve, the valve being configured to seal the exhaust port under normal operating conditions and to unseal the exhaust port when at least one of the batteries within the battery pack compartment enters into thermal runaway.
