The system allows the generation and distribution of energy on board a motor vehicle provided with a propulsion unit (E; PM), a tank (R) for fuel (F) at least one distribution network or line for electric energy (1-2; 2-3), electrical energy generation dev...

The system has operating units (7, 9) connected to a battery (1) across a power supply line (4). The power supply line is connected, to a controllable switch (10) whose opening and closing is controlled by a control unit (11), in parallel with power supply...

For vehicles with two electrical networks and corresponding charges at two different voltage levels, with two batteries at a first and at a second voltage level respectively, to which two networks a bi-directional converter is associated, with its input an...

A device, mounted on a hydraulic excavator, for allowing each of first and second electric motors (13), (14) to generate power by using electric power supplied from a power supply having a predetermined capacity, and actuating a boom cylinder (6), an arm c...

An electric device (1) in which a driver (4) drives an electric motor (5) by use of electric power supplied from a power supply (2) having a rechargeable secondary battery, and a controller (3) monitors, manages, and controls the driver and the whole devic...

The invention provides a circuit for supplying electric power to a load using a high voltage battery, the circuit supplying a dark current when the load is not being operated. A high voltage load and a low voltage load are attached to a battery and electri...
