Description
Technical field
The present invention relates to a kind of battery PACK cabinets, and in particular to a kind of novel combination type battery PACK cabinet.
Background technique
The voltage and comparision of quantity of electricity of battery PARK monomer are small, are not able to satisfy the battery applications of energy-storage system and electric car
It is required that needing the monomer series-connected battery group string for constituting voltage levels of multiple battery PARK.And for the ease of carrying, saving
Space and battery PARK can be protected effectively, more and more battery PACK are installed in PACK cabinet.
Current existing PACK cabinet, is that single battery core is put into battery core framework, then simultaneously by battery core framework one by one
It is listed in together, baffle is arranged in both ends, and then baffle and each battery core framework concatenation are fixed together by four angle stay bolts.So
And defect existing for the PACK body structure of this fixed structure has:
(1) it is not sufficiently stable, stay bolt supportive is bad, flexible deformation in handling process, causes in battery core framework mutually
Electrode connecting piece (electrode connecting piece is screwed) the generation Light deformation for connecting battery core leads to not the feelings of compacting
Condition, and then cause battery core resistivity inconsistent, the inconsistent consistency that will affect entire battery pack (PACK) of resistivity, consistency
Bad there is deviation (allow generally for deviation no more than 5%) and will affect the normal use of battery pack.
(2) usually in packaging technology, single battery core can be arranged in battery core framework, then each battery core framework is arranged side by side
Assembling, after framework is completed, is attached between the positive and negative tab of adjacent battery core by conductive connecting piece, each to realize
A battery core is connected.However because the positive and negative tab of single battery core is to stretch out upwards from battery core top, and battery core is positive and negative
Tab stretches out upwards not along two sides of battery core, i.e. the side of positive and negative anodes ear distance from bottom battery core there are certain vacant,
So there are the skies centainly without any object support between positive and negative anodes eardrum portion and battery core framework after the connection of positive and negative lug bending
It is remaining, once our battery core frameworks such as generate vibration, deformation etc. in the handling process or shake in use at the feelings in this way
Condition, it is easy to so that our positive and negative tab is deformed or connect loosening, and these situations can directly result in battery core resistivity
It changes, and then influences the consistency of entire assembled battery.
(3) resistivity of conductive connecting piece and the resistivity (battery core internal resistance is small) of cell polar ear are different, are difficult to protect
The resistivity for demonstrate,proving the two is consistent, this just affects the consistency of entire assembled battery.
Summary of the invention
To overcome the above-mentioned problems of the prior art, the present invention provides a kind of novel combination type battery PACK cabinets.
