Abstract

The invention relates to a distributed battery management system, which comprises at least two battery mould groups, each battery mould group is connected respectively with a battery management mould through a corresponding collecting mould that is externally connected with a jumper circuit. The invention also discloses a management method of the distributed battery management system. In respect of the method of the invention, the collecting mould is externally connected with the jumper circuit which is used for setting different states of I/O port of every collecting mould, a corresponding CAN bus address is given to each collecting mould by pointing to every state so as to distinguish signals sent by each collecting mould, thus resolving the communication dispute of the distributed battery management system.

Description

technical field [0001] The invention relates to the field of automotive electronics, in particular to a distributed battery management system and a management method thereof. Background technique [0002] With the increase of electric equipment, there are more and more applications of battery packs that can supply power. During the use of battery packs, the battery management system must monitor the voltage, current, and temperature of the battery cells in real time, so that the battery management system Accurately predict battery performance. [0003] Battery management is usually divided into centralized battery management system and distributed battery management system. Among them, the centralized battery management system has the advantages of simple structure and easy implementation, but the battery management system obtains the voltage and temperature of the battery cells through multiple signal harnesses. The number of battery cells will inevitably increase, requir...
