A method of managing charging of a traction battery and corresponding devices, the traction battery including a thermal regulating system, the thermal regulating system including a compressor, the method including transmitting information between a control device for the compressor and a device for managing the charging of the traction battery, before activating the compressor or before activating a device for charging the traction battery.

Method of managing the charging of a traction battery and corresponding devices

An electric power supply system for an electric vehicle, including a low-voltage network powering auxiliary devices of the vehicle and a high-voltage network powering a propulsion mechanism of the vehicle. The low-voltage network includes a low-voltage battery storing electric energy and a first converter connected to the high-voltage network powering the low-voltage network, while the high-voltage network includes a high-voltage battery and a switching mechanism isolating the high-voltage battery. The system further includes a first supervisor controlling the switching mechanism and a first monitoring mechanism determining if the charge of the low-voltage battery is below or above a first threshold, the supervisor configured to control the switching mechanism to connect the high-voltage battery if the first monitoring mechanism indicates the battery charge is below the first threshold.

Power supply system and method for an electric vehicle

A power-steering device and method for controlling a device for a motor vehicle including a stop and start system, the device including an electric pump unit including at least one electric motor and one processor. The method includes a stage in which the electric pump unit is switched to a standby mode by reducing rotation speed of the electric motor, this stage implemented by the processor following receipt of a control signal sent by the stop and start system to the processor, the signal representing an automatic switching of a heat engine into a stop mode. The method enables the power-steering device to be kept in operation during an automatic stopping phase of the heat engine, without resulting in unwanted noise or excessive electricity draw.
