FIELD: electricity.
SUBSTANCE: electric pulling chain (1) for motor vehicle has an on-board rechargeable power source (2). The pulling chain includes a static converter (5), configured to form a three-phase voltage system connected at the input to said rechargeable power supply (2). A three-phase electric motor (10), powered by the three-phase voltage system supplied by the static converter (5), has a stator coil configured to be connected to an external electric power source (35) to charge the on-board power source through the static converter (5). The motor (10) is a synchronous motor with separate excitation, wherein power supply to the rotor (23) is cut during the charging phase.
EFFECT: shorter time for charging an accumulator battery and higher safety when operating a vehicle.
