Battery management is divided into centralized battery management system and distributed battery management system usually.Wherein, the advantage of centralized battery management system is simple in structure, be easy to realize, but battery management system is voltage and the temperature value that obtains battery cell by many signal wire harness, but along with the rising of supplying cell group voltage requirements, battery cell quantity must increase, and needs the battery management controller that more interface resource is provided, increase a large amount of wire harness simultaneously, also increased the difficulty of battery cell failure diagnosis.Meanwhile, this system can not monitor in real time to the data acquisition target, can not in time reflect the sudden change situation of data acquisition object.
Secondly, the advantage of distributed battery management system is to can be good at battery cell is managed, and is easy to realize the equalization charging, and along with the increase of battery cell quantity, the interface resource of battery management controller is easy to expand, and the wire harness problem is easy to solve.But be accompanied by the increase of battery cell quantity, the quantity of data acquisition module is also wanted relative increase, and distributed battery management system adopts a plurality of data acquisition modules.For reducing cost, distributed battery management system adopts identical battery acquisition module, and this has just brought the CAN collision problem between the collection plate.
Facing to the communication between a plurality of data acquisition board and the battery management controller, solve the data communication conflict and become primary task, and the main method of current solution distributed management system communication conflict has two kinds: first kind is that each data acquisition system is used different programs, disposes different CAN bus ID; Second kind is to use products such as being similar to DS18B20, adds CAN bus ID automatically by hardware, solves the communication conflict.But these methods will increase the difficulty and the cost of production greatly undoubtedly.
Summary of the invention
Primary and foremost purpose of the present invention is to provide a kind of can solve communication conflict, difficulty is little, cost is low distributed battery management system.
For achieving the above object, a kind of distributed battery management system provided by the invention comprises at least two battery modules, and each battery modules links to each other with battery management module by corresponding acquisition module respectively, the external wire jumper circuit of acquisition module.
Another object of the present invention is to provide a kind of management method of distributed battery management system, this method comprises the step of following order:
(1) reads wire jumper information, and judge the state of each acquisition module I/O port;
(2), give each acquisition module corresponding C AN bus address according to the corresponding state of each acquisition module I/O port;
(3) each acquisition module carries out data acquisition to battery modules, and the data that collect are passed through the CAN bus transfer to battery management module;
(4) battery management module is differentiated the signal that acquisition module sends according to the CAN bus address, and carries out respective handling.
The present invention passes through at the external wire jumper circuit of acquisition module, utilize the wire jumper circuit state different to the I/O ports-settings of each acquisition module, give each acquisition module corresponding C AN bus address at each state, to distinguish the signal that each acquisition module sends, solved the communication conflict of distributed battery management system.
