METHOD FOR HEATING A TRACTION BATTERY BY MANAGING THE MOTOR TORQUE BETWEEN TWO WHEEL SETTINGS

Abstract

The present invention relates to a method for heating a traction battery (6) of an electrified vehicle, comprising the steps of determining a first distribution value (CTR1) of a setpoint torque at the wheels between a first set of wheels (3) driven by a first drive unit (2) and a second set of wheels (5) driven by a second electric drive machine (4) powered electrically by the traction battery (6), determining a second distribution value (CTR2) of the setpoint torque at the wheels, determining a temperature of the traction battery (6), and determining a setpoint distribution (CSCTR) of said setpoint torque at the wheels by calculating a centroid of the first distribution value (CTR1) and the second distribution value (CTR2) weighted by the determined temperature of the traction battery (6). The invention relates to hybrid and all-wheel-drive electric vehicles. Figure 1.
