Various disclosed embodiments include illustrative controller units, drive units, and methods. In an illustrative embodiment, a controller unit includes a controller electrically couplable to an inverter and a memory configured to store computer-executable instructions. The computer-executable instructions are configured to cause the controller to receive a battery heat request value, receive a torque command, generate a motor command responsive to the battery heat request value and the torque command, and send the motor command to the inverter to facilitate delivery of heat to a battery to achieve a target temperature while also causing a motor associated with a drive unit to operate at a level of torque that corresponds to the torque command.
