Charge power distribution system and method for dual-path charging

Abstract

A charge power distribution system for dual-path charging comprises a card-swiping unit, a system control unit, a charging module 1, a charging module 2, a power output switch unit and a charging output unit; the card swiping unit is used for obtaining user grade information; the charging module 1 and the charging module 2 are used for providing system charging output power; the power output switch unit is used for adjusting the output power of a charging interface; the charging output unit is used for outputting charging power and obtaining charging power demand information of a charged vehicle and feeding back the charging power demand information to the system control unit; the system control unit is used for controlling the power output switch unit according to the user grade information and the charging power demand information, which are fed back by the charging output unit, of the charged vehicle and a vehicle to be charged.

Description

technical field [0001] The invention relates to charger technology, in particular to a dual-channel charging charging power distribution system and method thereof. Background technique [0002] Among the current DC charger products on the market, most of the charger products are only chargers with a single charging gun, or even if there are chargers with double charging guns on the market, they are only composed of two independent single-gun chargers. An independent double-gun charger; or another switchable double-gun charger, in terms of function, it only adds a charging gun to the single-gun charger. [0003] The above three chargers have the following disadvantages: [0004] 1. A single charger cannot meet the charging requirements of multiple users at the same time, and the space occupied by a single charger is not much different from that of a charger with two or more charging guns. Therefore, compared with a double charger, a single The space utilization rate of the ...

AI Technical Summary

Problems solved by technology

[0004] 1. A single charger cannot meet the charging requirements of multiple users at the same time, and the space occupied by a single charger is not much different from that of a charger with two or more charging guns. Therefore, compared with a double charger, a single The space utilization rate of the gun charger is not high

[0005] 2. Only one set of chargers is charging for the stand-alone double-gun charger, and when the other set is idle, even if the charging power of the car charging is actually higher than that of a single set of chargers, it cannot be realized because it is independent Parallel machine, the interest rate of such an independent double gun charger equipment is relatively low, it cannot meet the user's fast charging requirements, and the cost is high

[0006] 3. The switchable double-gun charger can only charge two vehicles in different time periods, and cannot meet the requirements of both users charging at the same time
