Embodiment Construction

[0034] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, but not to limit the present invention.

[0035] The idea of ​​the present invention is: the present invention adopts the mode of combining double gun charging and single gun charging to charge the electric vehicle. Through the communication between the two chargers and the electric vehicle, it can be judged whether the charging state of the electric vehicle is single-gun charging or double-gun charging, so that the appropriate charging voltage and charging current can be flexibly selected to charge the electric vehicle .

[0036] First please refer to figure 1 , shows a block diagram of a specific embodiment of the double g...

Abstract

The invention discloses a double-gun charging system. The double-gun charging system comprises a first charger, a first charging gun, a second charger, a second charging gun and an electrical car, wherein the first charger is connected with the first charging gun, the second charger is connected with the second charging gun, the system can be in a single-gun charging state or a double-gun charging state, during single-gun charging, the single charger communicates with the electrical car and outputs a charging current and a charging voltage to charge the electrical car; during double-gun charging, sequence of the charging guns inserted into car charging seats is detected, the charger corresponding to the firstly-inserted charging gun is taken as the main charger, the secondly-inserted charger is taken as a secondary charger, the main charger communicates with the electrical car, the main charger distributes charging sub currents and charging voltages, and the main and secondary chargers output the charging voltages and the charging sub currents according to current distribution instructions. The invention further discloses a double-gun charging method. The double-gun charging system is advantaged in that a technical problem of low charging efficiency of a single charger is solved, and the charging time is shortened.

Description

technical field [0001] The invention relates to the technical field of electric vehicle charging, in particular to a double gun charging system and a double gun charging method. Background technique [0002] At present, new energy vehicles are still in their infancy, especially pure electric vehicles driven by electricity. New energy vehicles can effectively reduce the dependence on oil resources. Electric vehicles usually use conventional charging methods to replenish power. One of the reasons that has been hindering the vigorous promotion of electric vehicles at this stage is that electric vehicles have short battery life and relatively long charging time. [0003] It takes about two hours for the existing chargers on the market to fully charge an electric vehicle; however, it only takes about 5 minutes for a traditional fuel vehicle to fill up a tank of gas. [0004] At present, there are only single-gun chargers and electric vehicles with single charging sockets on the ...
