An electric motor assembly includes a multi-phase electric motor, a battery of accumulators, an inverter configured to convert the direct current of the battery into multi-phase alternating current adapted to supply the motor, and a connection housing. The connection housing includes plugs allowing connection of motor phases, the battery terminals, and at least five connections to the inverter. The housing further includes a group of contacts allowing it to be connected to a single phase mains system, and a group of contacts allowing it to be connected a multi-phase mains system. The housing includes switches according to the position of which the system including the housing, the battery, the inverter, and the motor connected solely by its phases, alternatively allows the motor to be supplied from the battery, the battery to be recharged directly from a single-phase mains system, and the battery to be recharged from multi-phase mains system.

Electric motor assembly rechargeable from an electrical mains system, and dedicated connection housing

A device for generating electric power of a traction system of a motor vehicle powered by a battery, including a first rectifier stage configured to be connected to a power supply network or to a load to be powered, a second inverter stage configured to be connected to the battery, a mechanism regulating average current flowing between the first stage and the second stage, and a controller controlling a transfer of electric power between the power supply network and the battery or the powering of a load.

Rapid reversible charging device for an electric vehicle

A device for charging a battery including a rectifier input stage configured to be connected to a power supply network and an inverter output stage configured to be connected to the battery, and a mechanism regulating average current obtained from the input stage about a current value generated from the maximum current supplied by the power supply network and according to a coefficient that is at least equal to a ratio between the maximum voltage rectified by the input stage and the battery voltage.

Fast charging device for an electric vehicle

An interconnection housing for a motor vehicle, including connection terminals for a battery and connection terminals for an inverter. The housing includes connection terminals for an external electric power supply and outlets for connection to an AC electric motor, such that the battery can be recharged when the external power supply, the inverter, the electric motor, and the battery are all connected simultaneously to the interconnection housing.
