Problems solved by technology

This method is too cumbersome and requires a charger with a corresponding voltage, which cannot cope with temporary emergencies
For the energy storage cabinet of the high-voltage system, there is no corresponding charger on the market, so it is not applicable
And it is unsafe to directly charge the battery by bypassing the protection system

Abstract

The invention relates to a BMS battery management system suitable for an energy storage cabinet, and a management method thereof. The system comprises a high-voltage control box, wherein one side of the high-voltage control box is provided with a positive electrode interface and a negative electrode interface which are connected with a battery assembly, the other side of the high-voltage control box is provided with a charging and discharging positive interface and a charging and discharging negative interface which are connected with an energy storage converter, a main relay assembly is arranged in the high-voltage control box and connected with the positive electrode interface, the high-voltage control box is provided with an aviation plug assembly, the aviation plug assembly is connected with a battery management assembly, the aviation plug assembly is further connected with a current sensor, and a direct-current power supply module is further arranged in the high-voltage control box. According to the invention, when the highest-level alarm of undervoltage of a discharge single body is reached, a main positive relay is switched off, and then a self-locking relay is switched offafter 30 seconds of delay; and when the system is powered on, comparison and judgment are carried out and corresponding operation is executed, so that the problem that the energy storage system is halted and cannot be started due to the power consumption of the system in a standby state is solved.

Description

technical field [0001] The invention relates to a battery management system and a management method thereof, in particular to a BMS battery management system and a management method suitable for an energy storage cabinet. Background technique [0002] The main purpose of the BMS battery management system is to guarantee the design performance of the battery system and provide functions from safety to durability and power performance. In terms of safety, that is, the BMS management system can protect battery cells or battery packs from damage and prevent safety accidents. In terms of durability, that is, the battery works in a reliable and safe manner within the area to prolong the battery life. In terms of power supply, that is, the working state of the battery should be maintained under certain conditions to meet the requirements of the energy storage system. [0003] As far as the existing management system is concerned, when the system is in the standby state for a long...
