CHARGER FOR ACCUMULATOR, NETWORK OF SEVERAL CHARGERS AND METHOD OF THEIR OPERATION

摘要

FIELD: electricity.;SUBSTANCE: this invention is referred to a network of several chargers for accumulators of electric vehicles. Each charger comprises the first power connection to exchange energy with a power supply source, an energy converter, which converts the energy from the power source to a charging current of a suitable value for charging of the electric vehicles, the second power connection to exchange energy with an electric vehicle, at least the third power connection to exchange energy with another charger. The device comprises a controlled power switch connected to the energy converter, to the second power connection and to at least the third power connection. The device comprises a controller to control the switch configured so that the energy converter is connected to the second power connection when it is required to charge the accumulator of the electric vehicle, to connect the energy converter to at least one third power connection when it is required to transmit power to another charger, and to connect at least one third power connection to the second one when it is required to transmit energy from another charger to the accumulator of the electric vehicle.;EFFECT: development of a more powerful charging system with several charging connections.;16 cl, 4 dwg
