Abstract: A powertrain system including a first housing, a first electric motor that drives a first wheel, a first inverter coupled to the first electric motor, a first gear reducer coupled to the first electric motor. The first gear reducer couples to a first wheel. The powertrain system also includes a second electric motor that drives a second wheel, a second inverter coupled to the second electric motor, a second gear reducer coupled to the second electric motor. The second gear reducer couples to a second wheel. The housing houses the first electric motor, the first inverter, the first gear reducer, the second electric motor, second inverter, and the second gear reducer.

Abstract: A method of manufacturing a battery pack for an electric vehicle is disclosed. The method includes placing a cooling duct between first and second pluralities of battery cells, and applying a first force to the first plurality of battery cells and a second force to the second plurality of batteries. The first and second forces cause the first and second pluralities of battery cells to press against the cooling duct, the first plurality of battery cells is pressed against a first side of the cooling duct, the second plurality of battery cells is pressed against a second side of the cooling duct, and the first side of the cooling duct is opposite the second side of the cooling duct. The method also includes placing the first and second plurality of battery cells in a first tray configured to hold the first and second plurality of battery cells.

Abstract: A battery pack for an electric vehicle is disclosed. The battery pack includes an upper tray, a first busbar attached to the upper tray, a lower tray, and a second busbar attached to the lower tray. The battery pack also includes a plurality of battery cells arranged in the upper and lower trays, and a cooling duct mechanically connecting the lower tray to the upper tray.

Abstract: A rechargeable battery system, a battery pack, and methods of manufacturing the same are disclosed herein. The rechargeable battery system and/or battery pack can be for an electric vehicle. The rechargeable battery system and/or battery pack can include a plurality of battery cells arranged into one or more rows, a busbar, and a housing. The housing can include a plurality of receptacles that can engage with the plurality of battery cells to secure a relative position of the plurality of battery cells with respect to each other. The housing can define a cooling duct in thermal connection with the plurality of receptacles.
