Abstract: A reconfigurable power distribution network having a number of power lines; and a number of switches for carrying electric power between the power lines and electric user devices. An electronic control unit is provided to safety control the switches, on the basis of incoming signals indicating a short-circuit/overload in the network, and on the basis of electric power flow through the switches, to reconfigure the network upon detection of a short-circuit or overload.

Abstract: A supply unit including a direct voltage energy source formed of a number of rechargeable batteries; an electric motor for driving the vehicle; and an electric circuit interposed between the direct voltage energy source and the electric motor. The electric circuit is reconfigurable, and provides for a first operating mode to control the alternating supply voltage of the motor, and a second operating mode, alternative to the first operating mode, and wherein the reconfigurable circuit provides for rectifying an alternating voltage to recharge the batteries.
