Abstract
An electric vehicle includes an energy storage system, an integrated drive system assembly having a gearbox, a power inverter, and an electric motor, wherein the gearbox, the electric motor and the power inverter are assembled into a single unit with a multi-piece housing. The electric vehicle may also include two half shafts for respective wheels of the electric vehicle. The gearbox, the electric motor and the power inverter may be oriented such that the gearbox extends along a center line of the electric vehicle and the electric motor and the power inverter extend from the gearbox in opposite directions. The electric vehicle may also include a mutual thermal management system coupled to the integrated drive system assembly and having at least one liquid coolant loop that is thermally coupled to the electric motor, the power inverter, the gearbox, a cooling system, a refrigeration system, and an HVAC system.
