Apply mode, the every other embodiment that those of ordinary skill in the art are obtained under the premise of creative work is not made,
Belong to the scope of protection of the invention.
Referring to Fig. 1, a kind of BMS that the present invention is provided wakes up system 100, including battery bag 10 and BMS20, it is described
BMS20 includes main computer unit 21 and appendent computer system 22, and the appendent computer system 22 includes control module 221 and acquisition module 222.Institute
Stating battery bag 10 is used to provide power for electric automobile.In the present embodiment, the battery bag 10 includes some cells.
It is to be appreciated that above-mentioned each functional module can be stored in memory in form of software programs, or with specific function
Hardware, for example, burning has the chip of particular software application.
Above-mentioned each functional module is described in detail with reference to Fig. 2.
As shown in Fig. 2 it is the flow chart of BMS awakening methods in the embodiment of the present invention.It should be noted that, it is of the invention
Method is not limited to the order of following step, and in other embodiment, method of the invention can only include step as described below
Rapid a portion, or part steps therein can be deleted.
Step S01, the acquisition module 222 gathers the status information of the battery bag 10.
In the present embodiment, the status information of the battery bag 10 includes total voltage, total current, the residue of battery bag 10
Electricity and temperature.
Step S02, the acquisition module 222 judges whether the status information is normal.If the status information is normal, this
Shi Suoshu main computer units 21 and the control module 221 in a dormant state, the normal work of acquisition module 222, the master
