In an electric vehicle charging and traction system with an inverter configured to be coupled to at most one DC power source and provide AC power, a first motor coupled to the inverter, a second motor coupled to the first motor, a converter coupled to the second motor and to a rechargeable DC power unit, and a switching mechanism configured to control coupling or decoupling of the inverter: in charging mode, decouple the inverter from the rechargeable DC power unit, couple the inverter to a second DC power source, and run the first motor at speed in a first direction and the second motor with negative torque to generate current; and in traction mode, decouple the inverter from the second DC power source, couple the inverter to the rechargeable DC power unit, and run the first and second motors with nonzero torque in a same torque direction.
