Problems solved by technology

However, this system still does not solve the problem when the demand current of electric vehicles exceeds the maximum output capacity of a single gun, so it cannot meet the charging needs of some models
[0004] Specifically, some models have two DC charging ports, and ordinary electric vehicles have one. When the power demand of these special electric vehicles exceeds the single-gun output capacity of the charging device, it cannot meet the charging requirements of the model, such as single-gun The maximum output current is 250A. When the car's demand is greater than 250A, it cannot meet the charging demand.

Abstract

This disclosure proposes a method and system for simultaneously charging an electric vehicle with multiple charging guns of a charging device, inserting multiple charging guns into multiple DC charging ports of the electric vehicle to be charged; judging whether each charging gun has a message Answer, if only one charging gun detects the interactive message, the electric vehicle to be charged is a single BMS model, if each charging gun can detect the interactive message, then the electric vehicle to be charged is a multi-BMS model; for a single BMS model , if each charging port can detect the battery voltage, the BMS demand current is evenly distributed to each charging gun, and the output current of each charging gun is adjusted to charge; for multi-BMS models, if each charging port The battery voltage can be detected, and the power output of each charging gun is automatically adjusted according to the charging demand of each BMS. The disclosure solves the problem that multiple charging guns charge an electric vehicle at the same time.

Description

Technical field[0001]The present disclosure relates to the technical field of electric vehicle charging equipment, and in particular to a method and system for simultaneously charging an electric vehicle with multiple charging guns of the charging equipment.Background technique[0002]With the popularization of new energy electric vehicles, electric vehicle charging equipment has also entered a stage of rapid development. However, due to the current single-gun output power limitation, high-power charging equipment cannot output all its power to a car, which wastes the cost of charging equipment. The power lengthens the charging time of electric vehicles.[0003]The patent number is "CN201820152865.3", and the patent name is "A dual-gun charging pile control system with free power distribution". The system automatically adjusts the output power distribution of a single gun according to the current demand of the car to meet the needs of the car. However, this system still does not solve t...
