Problems solved by technology

At this time, the voltage difference between the output voltage of the module and the battery voltage determines the size of the inrush current. If the charging module changes from constant voltage to constant current or the rate of constant power is slow, the output voltage of the charging module will continue to rise. Too high and too fast, in the conversion process, there will be an inrush current, which will further impact the battery

Abstract

The invention discloses a control method and system for reducing an impact current of a charging pile. The system comprises a monitoring system and a charging module. The charging module is connected with an electric vehicle battery through a switch; and the monitoring system communicates with the electric vehicle battery and the charging module, after the monitoring system receives a switch closing instruction, an instruction issued by an electric vehicle is transmitted to the charging pile, the charging pile is switched to a constant-current charging mode after receiving the instruction, and constant-current charging is directly carried out after starting in the constant-current mode. After the charging pile is additionally provided with a constant-current charging mode charging starting and output buffer circuit, a problem that the charging pile does not respond to a constant-current charging request of the charging vehicle is solved, the impact current is not generated in the charging pre-charging stage and the charging pause stage, and the requirement of the vehicle BMS for the current is better responded.

Description

technical field [0001] The disclosure belongs to the technical field of charging, and in particular relates to a control method and system for reducing inrush current of a charging pile. Background technique [0002] The statements in this section merely provide background information related to the present disclosure and do not necessarily constitute prior art. [0003] With the promotion of electric vehicles, the batteries on the matching electric vehicles also have their own models, and the voltage and current resistance of the batteries are also different. Prolonging the life of the batteries is also an important task. At the same time, each manufacturer of the charging module for charging the battery of an electric vehicle also has a different output voltage and output power. When the output control of the charging module does not cooperate well with the battery, it is easy to cause damage to the battery by the charging module. [0004] At present, the output of the c...
