Abstract: A platform to replace under-the-hood engine assembly of a conventional internal combustion engine vehicle. The platform includes a backbone frame and a tower frame secured to the backbone frame towards a vehicle front. The backbone frame and the tower frame are secured to chassis frame of the vehicle through a three point isolator mounting system. A plurality of electric drive components, such as battery radiators, electric-axle and high-voltage accessories cooling system radiator, air conditioning condenser, cooling fans, brake retarder, DC-DC voltage converter(s), HVAC compressor, inverter(s), low voltage batteries package, air compressor, pumps, etc. are secured to the backbone frame and the tower frame to support the electric motor of the electric vehicle.

Abstract: An electric vehicle includes a chassis, a rigid axle housing, and a suspension system control arm coupling the rigid axle housing to the chassis. The electric vehicle also includes first and second electric motors, each having a rotator and a stator. The stator of the first and second electric motors are rigidly fixed to the rigid axle housing. The electric vehicle also includes a coolant supply system coupled to a radiator and the rigid axle housing to supply coolant from the radiator to a coolant inlet of the rigid axle housing and to supply used coolant from a coolant outlet of the rigid axle housing to the radiator. A first mounting bracket is fixed to the chassis and the coolant supply system. A second mounting bracket is fixed to the rigid axle housing and the coolant supply system, and a third mounting bracket is fixed to the control arm and the coolant supply system.
