Description of drawings
The purpose of the utility model, advantage and characteristics will illustrate through the non-limitative illustration of following preferred embodiment and explain.These embodiment only are the prominent examples of using the utility model technical scheme, and all technical schemes of taking to be equal to replacement or equivalent transformation and forming all drop within the scope of the utility model requirement protection.
Fig. 1 is the organigram of lithium ion battery module.
Embodiment
Lithium ion battery module as shown in Figure 1 includes module housing 1, and its unusual part is: be provided with the lithium ion battery group in the module housing 1 that the utility model adopted.Specifically, the lithium ion battery group includes at least two lithium-ion battery monomers 2 to be formed, and carries out connection in series-parallel through circuit connecting plate 3 between the lithium-ion battery monomer 2.Consider with the effective of follow-up electricity consumption device to combine, on module housing 1, be distributed with anodal ejector 4 and negative pole ejector 5, this positive pole ejector 4 links to each other with the lithium ion battery group is anodal, and negative pole ejector 5 links to each other with lithium ion battery group negative pole.Simultaneously, from consideration safe in utilization, in module housing 1, be provided with bursting diaphragm.
With regard to the utility model one preferred implementation,, directly link to each other between circuit connecting plate 3 and the lithium-ion battery monomer 2 in order the running of lithium-ion battery monomer 2 to be coordinated control.Certainly, consider the needs of some special use occasion, also can be circuit connecting plate 3 with lithium-ion battery monomer 2 between link to each other through conductor.
Further, the bursting diaphragm that the utility model adopted includes assisting base plate 6, is distributed with sharp object 7 on the described assisting base plate 6.Like this, when lithium-ion battery monomer 2 is in normal condition, directly do not contact between sharp object 7 and battery cell, avoid occurring puncturing the false triggering of lithium-ion battery monomer 2.Corresponding is that when lithium-ion battery monomer 2 is in abnormality, sharp object 7 matter will directly contact with cell with it.Specifically, when lithium-ion battery monomer 2 was in abnormality, it the bulging situation can occur, and the increase meeting that is accompanied by lithium-ion battery monomer 2 volumes contacts with sharp object 7, causes sharp object 7 to puncture lithium-ion battery monomer 2, and release pressure improves its fail safe.
