Abstract
A vehicle provided with an electric propulsion system and a method for controlling the electric propulsion system are provided. The system includes a first Electrical Motor (EM) connected via first Electrical Connections (EC) to an on-board Energy Storage System (ESS) and drivingly connected to wheels. The system further includes a second Electrical Motor (EM) connected via second Electrical Connections (EC) to one or several electrical energy sources and drivingly connected to wheels. The system is controlled by an Electronic Control Unit (ECU) and the Electrical Motors (EM, EM) are used in dependence of the State Of Charge (SOC) level in the first Energy Storage System (ESS) and the availability of electrical energy for the second Electrical Motor (EM). The ECU is programmed to include an energy transfer mode in which the use of the second Electric Motor (EM) for propulsive force is increased and the use of the first Electric Motor (EM) for regenerative breaking is increased when the State Of Charge (SOC) level in the first electrical Energy Storage System (ESS) is below a defined level and it is estimated that there is more electrical energy available for the second Electrical Motor (EM) than for the first Electrical Motor (EM).
