CHARGING SYSTEM FOR ELECTRIC CARS Russian patent published in 2018 - IPC B60S5/00 B60L11/18 H02J7/02 

FIELD: electrical engineering.

SUBSTANCE: invention relates to a charging system for electric cars. System contains at least one charging station, a power electronic circuit, at least one electric power storage device, a secondary cooling device, and at least one heat storage device. Traction battery of the electric car is connected to the charging station through a charging cable. Supply network provides a certain electrical network power. Charging station can be connected to the mains through the power electronic circuit. At least one electric power storage device is connected between the mains and the corresponding charging station. Electricity storage can be charged based on the electrical power transmitting facility of supply mains. Drive may be discharged based on the charging speed of the electric vehicle charging station. Charging station, the power electronics and at least one drive can be connected to a secondary cooling device that provides a certain heat capacity of the secondary cooling. At least one heat accumulator is connected to the secondary cooling device, to the charging station, to the power electronic circuit and to at least one electric power storage device. Heat accumulator or the cooling medium of the heat accumulator can be heated on the basis of the power losses of the power electronic circuit, the charging station and the energy storage, and can also be cooled on the basis of the heat capacity of the secondary cooling of the secondary cooling device.

EFFECT: invention allows to increase the speed of charging electric cars.
