ENHANCED STATIC HEATING OF EV BATTERY PACK USING DRIVE UNITS

An electric vehicle (EV) includes a battery pack, an electric motor, a drive circuit configured to drive the electric motor, a heat transfer material, arranged to transfer thermal energy from the electric motor to the battery pack, and a controller. The controller is configured to determine that the EV is connected to an external charger. In response, the controller generates the control signals comprising a waveform pattern that is free of zero volt vectors. The controller transmits the control signals to the drive circuit to drive the electric motor in accordance with the waveform pattern while the external charger charges the battery pack.
