Problems solved by technology

However, in the method of identifying the communication address through the daisy chain mode, the working communication of the battery management system is also in the daisy chain mode, and the working communication efficiency is low.
Therefore, in general, the traditional method of setting the address of the battery management unit is inefficient

Abstract

The present invention relates to a cell management unit, a cell management system, a communication management method and system of the cell management system. The cell management unit comprises a processing apparatus, a working communication interface, an address setting interface and a selection switch. The processing apparatus is connected with a cell cluster management unit or the address setting interface of a previous cell management unit by using the working communication interface. The address setting interface is connected with the working communication interface of a next cell management unit or the cell cluster management unit. One end of the selection switch is connected with the address setting interface. The processing apparatus controls the other end of the selection switch to connect with the processing apparatus, so as to enable the address setting interface to connect with the processing apparatus, so that a plurality of cell management units form a Daisy chain structure. The processing apparatus controls the other end of the selection switch to connect with the working communication interface, so as to enable an address communication interface to connect with the working communication interface to allow the plurality of cell management units to from a bus structure. Due to switch between the Daisy chain structure and the bus structure, switch between automatic address setting and bus communication is realized, so that the efficiency is high.

Description

technical field [0001] The present invention relates to the technical field of battery management, in particular to a battery management unit, a battery management system and a communication management method and system thereof. Background technique [0002] The battery management system is used to monitor the state of the battery, prevent the battery from overcharging and overdischarging, prolong the service life of the battery, and improve the utilization rate of the battery. The same battery management system can manage multiple battery clusters connected in parallel, and each battery cluster is composed of multiple battery management units connected in series. The battery management unit is the smallest management unit and is stored on the battery cabinet / battery rack. [0003] Since the battery management system mostly adopts a multi-level architecture, and the level-level buses are connected, in order to realize communication, a unique address must be set for each bat...
