Problems solved by technology

However, in the existing MOS tube parallel connection scheme of the battery management system, board burning phenomenon often occurs, because the connected inverter will have a relatively large surge current when it is turned on, and the battery is prone to voltage in the process of charging and discharging. Inconsistent conditions, resulting in a large circulating current, damaging the BMS
Therefore, there is a need for a new technical solution that can solve the problem of damaging the BMS due to the impact of surges and circulating currents, and has higher reliability and safety.

Abstract

The invention relates to a low-voltage parallel battery management system and method. The system comprises multiple battery modules, a high-voltage box, an uninterruptible power supply (UPS) and a display screen, the battery modules are connected in parallel in a busbar manner and then are connected with the high-voltage box; the high-voltage box is connected with the display screen; the UPS is connected with the high-voltage box; the battery module is loaded through the high-voltage box; the UPS charges and discharges the battery module through the high-voltage box; and the battery module communicates with the display through the high-voltage box. According to the scheme, the problem that the BMS is damaged due to impact caused by surge and circulation is solved, and higher reliability and safety are achieved.

Description

technical field [0001] The invention relates to the technical field of battery energy storage, in particular to a low-voltage parallel battery management system and method. Background technique [0002] In the technical field of battery energy storage, a battery management system (Battery Management System, BMS for English abbreviation) is usually used to manage the battery, so as to ensure the safe and efficient operation of the battery system. However, in the existing MOS tube parallel connection scheme of the battery management system, board burning phenomenon often occurs, because the connected inverter will have a relatively large surge current when it is turned on, and the battery is prone to voltage during charging and discharging. Inconsistencies will generate a large circulating current and damage the BMS. Therefore, there is a need for a new technical solution that can solve the problem of damage to the BMS due to the impact caused by surges and circulating curren...
