Battery on-line monitoring and control function, eliminates difference between battery cell, it is ensured that battery with two side terminals in group；Solve wherein certain economize on electricity
When pond monomer breaks down, the drawbacks of whole battery modules are collapsed immediately improves battery utilization rate and reliability, while mitigating dimension
Repair work.
The present invention to achieve the above object, is realized using following technical scheme：
A kind of battery modules series connection management circuit, including some battery cells being sequentially connected in series, often save the battery cell and go here and there
First electronic switch is associated with, the two ends for the series circuit that each first electronic switch is constituted with corresponding battery cell
It is parallel with second electronic switch.
Further, as optimal technical scheme, first electronic switch and second electronic switch are controllable
Type electronic switch.
Further, as optimal technical scheme, first electronic switch and second electronic switch are MOS
Pipe.
The present invention compared with prior art, with advantages below and beneficial effect：
（1）The present invention is by the way that on the basis of classical tandem cell, increase is connected and in parallel at each batteries monomer
Controllable type electronic switch be metal-oxide-semiconductor, realize the quick of switch and turn on and off, can effectively overcome in battery modules because a certain
After individual or multiple battery cells break down, cause the drawbacks of whole battery pack is collapsed immediately, improve the stabilization of battery system
Property, reliability and security.
（2）The present invention can adjust the two of each battery cell in time according to normal/malfunction of cell in module
Switch/closure state of individual controllable type electronic switch, realizes the accurate monitoring and control to battery cell, improves whole electricity
Pond module it is intelligent.
（3）The present invention without taking the measure changed or repaired immediately to the fail battery monomer in battery modules, effectively
Frequency of maintenance is reduced, manpower maintenance cost is greatly reduced；On the other hand, the input of maintained equipment is also reduced, is improved
The management of whole battery modules, maintenance levels.
