Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete
Site preparation is described, it is clear that described embodiment is only a part of embodiment of the invention, rather than whole embodiments.It is based on
Embodiment in the present invention, it is every other that those of ordinary skill in the art are obtained under the premise of creative work is not made
Embodiment, belongs to the scope of protection of the invention.
Refer to Fig. 1-2, a kind of BMS distributing centralized management systems for lithium ionic cell module.It is characterized in that：
Multiple lithium battery voltages in each lithium ion battery module, temperature, current measurement value are passed through into the CAN mouthful of module and its
Its k（K ＞ 1）The CAN mouthful parallel connection of individual Modularized lithium battery is uploaded to host computer BMS（Central control unit or electronic vapour
Car vehicle management system）It is uniformly processed, manages and show, see Fig. 1.
Lithium battery module is in n（N ＞ 1）In the lithium battery module of string, slave computer BMS acquisition modules（Cell tube in module
Manage system circuit board）, it is that voltage, electric current, temperature acquisition are carried out to the n series lithium batteries in module and is measured that it, which is acted on, and is passed through
CAN mouthful on circuit board is uploaded, and is kept and external communication, is seen Fig. 2.
Host computer BMS（Central control unit or electric automobile management system）, each module data of upload will be gathered（Electricity
Pressure, electric current, temperature etc.）Managed concentratedly, through background process computing, and by touch screen number show battery running status and
Alarm indication.
Host computer BMS（Central control unit or electric automobile management system）, can be by touch screen to lithium electricity in each module
The number n and number of modules k in pond are arbitrarily set.
System can be carried out according to used battery pack k1 ~ Kn quantity by major loop B+ and B- and CAN data port
Connected between any module, distributing BMS does not influence major loop connection in series-parallel with leading back to be dielectrically separated from, must be one by one without upper and lower computer
