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

The invention provides a method and system for simultaneously charging one electric vehicle by multiple charging guns of charging equipment. The method comprises the steps of inserting the multiple charging guns into multiple direct-current charging ports of a to-be-charged electric vehicle respectively; judging whether each charging gun has a message response or not, if only one charging gun detects an interaction message, determining that the to-be-charged electric vehicle is a single BMS vehicle type, and if each charging gun detects the interaction message, determining that the to-be-charged electric vehicle is a multi-BMS vehicle type; for a single BMS vehicle type, if each charging port can detect the battery voltage, distributing the required current of the BMS averagely to each charging gun, adjusting the output current of each charging gun, and carrying out charging; for a multi-BMS vehicle type, if each charging port can detect the battery voltage, adjusting the power outputof each charging gun automatically according to the charging demand of each BMS. The problem that a plurality of charging guns charge one electric vehicle at the same time is solved.

Description

technical field [0001] The present disclosure relates to the technical field of electric vehicle charging equipment, in particular to a method and a system for simultaneously charging an electric vehicle with multiple charging guns of the charging equipment. Background technique [0002] With the popularity of new energy electric vehicles, electric vehicle charging equipment has also entered a stage of rapid development. However, due to the current limitation of the output power of a single gun, high-power charging equipment cannot output its full power to a vehicle, which wastes the cost of charging equipment. The power in turn extends 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 single gun output power distribution according to the current demand of the car to meet the needs of the car. However, th...
