Abstract:
An electrical power supply for a hybrid or electric motor vehicle includes a first power source to supply a voltage network of the vehicle, a second power source to supply the voltage network of the vehicle and/or to recharge the first power source, and a control module to control a safety structure of the first power source and of the second power source. The electrical power supply includes a metal casing containing the first power source, the second power source, the control module and the safety structure. The safety structure is common to the two power sources.
Abstract:
A method discharges the electrical circuit of a vehicle including at least one traction electric machine and equipped with an electrical supply network including a high-voltage battery and a hydrogen-fuel-cell stack that is associated with a voltage converter, with a high-voltage consumption network including the machine associated with an inverter and appended pieces of equipment, and with a drive module. The discharging method includes the following successive steps: stopping the vehicle, electrically disconnecting the battery from the network, interrupting the supply of hydrogen to the stack, and discharging energy from the electrical circuit into the stator winding of the machine by driving the voltage converter via the drive module.
Abstract:
A device for electrically powering an electric motor of a motor vehicle includes first energy source, a second energy source, and a memory module in which is stored a value of a maximum operating power that can be provided by the second energy source. This maximum operating power value is a function of the cooling capacity of the second energy source.
Abstract:
A method for heating fuel upon start-up of a hybrid vehicle combustion engine, in which method temperature of fuel and temperature outside the vehicle are compared against a first threshold below which starting of the vehicle is forbidden, and against a second threshold higher than the first threshold and above which the engine will start without the fuel being heated. The fuel is heated by exchange of heat with a cooling circuit for the vehicle battery when the external temperature is between the two thresholds.
