Double-charging-gun control system and method

Abstract

Provided are a double-charging-gun control system and method. The system comprises a charging device and an electromobile charging device. The charging device comprises a first charger, a first charging gun, a second charger and a second charging gun, wherein one end of the first charging gun is electrically connected to the first charger, and one end of the second charging gun is electrically connected to the second charger. The electromobile charging device comprises an electromobile-mounted BMS module, a master charging station and a slave charging station. The electromobile-mounted BMS module is used for controlling the first charger or the second charger to charge one electromobile when the first charging gun or the second charging gun is inserted into the master charging station, the electromobile-mounted BMS module is further used for controlling the first charger or the second charger to charge one electromobile according to the distributed output current when the first charging gun and the second charging gun are inserted into the main charging station and the slave charging station respectively. By means of the double-charging-gun control system and method, the double charging guns can charge one electromobile simultaneously, and charging time is shortened; one charging gun can be utilized to charge one electromobile, and the charging devices are fully utilized.

Description

technical field [0001] The invention relates to the field of rechargeable batteries, more specifically, to a rechargeable battery pack system. Background technique [0002] At present, the energy of traditional fuel vehicles mainly depends on oil, and the shortage of oil and the serious environmental pollution caused by the tail gas emitted by fuel vehicles have made it more and more urgent for human beings to research new green vehicles. As a green transportation tool, electric vehicles not only have remarkable energy-saving effects, but also greatly improve the comprehensive utilization rate of energy, and have obvious environmental benefits. Compared with traditional vehicles, they emit zero greenhouse gases. With the continuous improvement of the rechargeable battery manufacturing process, electric vehicles will have the strength to compete with traditional fuel vehicles in the not-too-distant future. Household or public electric vehicles have brought great convenience ...

Problems solved by technology

However, the current charging equipment can only charge one-to-one electric vehicles, and the charging time is long, so that the electric vehicles need to carry a large capacity battery to ensure that they can run enough miles, and there is enough time at night to charge When the electric vehicle is fully charged, the time it takes to charge the electric vehicle is much longer than the refueling time of the traditional vehicle, which causes a waste of time and makes the use of the electric vehicle inconvenient
