Abstract
An electric propulsion system for a paver machine is disclosed. The system includes a battery and a plurality of electric motors connected to an inverter and powered by an electrical current injection from the battery. A plurality of wheels are propelled by the plurality of electric motors. A control unit employs a traction control operation which commands a second current injection into the plurality of electric motors, compares an actual speed to a maximum speed threshold of the plurality of electric motors, determine instances of slippage based on the actual speed and the maximum speed threshold, and modulates, upon instances of slippage, the first current to the plurality of electric motors from the inverter to change the actual speed and implement a traction control.
