Abstract: A cell management module for a power supply module including a plurality of power cells includes at least one cell-sensing circuit and a current measurement circuit connected to the at least one cell-sensing circuit. The at least one cell-sensing circuit includes a transformer having a first winding and a second winding inductively coupled to the first winding. A first sub-circuit of the cell-sensing circuit includes the first winding of the transformer and is operable to selectively pulse a first signal through the first winding. A second sub-circuit of the cell-sensing circuit includes the second winding of the transformer and one of the power cells of the power supply module. The current measurement circuit is connected to the first sub-circuit of the at least one cell-sensing circuit and infers a voltage of the power cell based on a measured current of the first signal.

Abstract: An axle assembly for a vehicle includes a frame, a motor, and a pair of gear reduction subassemblies. The frame extends between a first distal end and a second distal end. The second distal end opposes the first distal end. The motor is secured to the frame between the first distal end and the second distal end. The pair of gear reduction subassemblies are rotatably coupled to the first distal end and the second distal end and configured to drive rotation from the motor to a pair of wheels. Each gear reduction subassembly includes a plurality of gears defining a plurality of gear ratios.
