Abstract: An electrical power supply system for an electrically powered motor vehicle, said vehicle including an electric motor, and a transmission device for transmitting energy between the drive wheels and the motor, said vehicle further including electrical accessories, in particular an air-conditioning device. Said system comprises a first rechargeable battery serving to power the electric motor and a second rechargeable battery serving to power the electrical accessories of the vehicle, the batteries being connected in parallel to the motor. The invention also relates to a method for controlling such a system.

Abstract: The invention concerns an off-road vehicle, in particular of the amphibious type, having a left wheel-train (6, 7, 8) and a right wheel-train, arranged to propel the vehicle on both land and water, propulsion resources (10) to drive the said wheel trains, and mobile control resources (15) capable of supplying at least one control signal as a function of their position. The said propulsion resources include a first electric motor capable of driving the left wheel-train, a second electric motor capable of driving the right wheel-train, and synchronisation resources (16) to synchronise the two electric motors as a function of the control signal.
