BATTERY HEATING DURING VEHICLE MOTION

A battery heating system including an inverter for transforming a DC current into a first AC current having a first phase, a second AC current having a second phase, and a third AC current having a third phase, a battery for supplying the DC current to the inverter and wherein an AC component is superimposed on the DC current and wherein the battery is heated in response to the AC component via ohmic losses, and a three phase electric motor configured to generate an electromagnetic torque having a quadrature component and a direct component in response to the first AC current, the second AC current and the third AC current wherein the inverter is configured to adjust the first phase, the second phase and the third phase resulting in the direct component having a non-zero magnitude and the quadrature component such that the electromagnetic torque has a zero magnitude.
