Description
Technical field
The utility model relates to battery pack, relates in particular to a kind of for the bilayer cells group on the electric automobile.
Background technology
Automobile is a kind of important vehicles, but along with the continuous deterioration of the day by day in short supply and natural environment of global energy, in order to reduce the pollution discharge capacity of city automobile, realizes the development strategy of new-energy automobile, and Development of EV is the current most important thing.Wherein storage battery is one of basic power source that provides power to electric automobile: in pure electric automobile, the effect of storage battery is the only power source of automobile driving system; And in the hybrid vehicle of equipment conventional engines (or fuel cell) and storage battery, storage battery both can have been played the part of the role of automobile driving system main power source, also can serve as the role of auxiliary power source.Namely when automobile low speed and startup, that storage battery is played the part of is the role of automobile driving system main power source; When full load was accelerated, that serve as was the role of auxiliary power source; Normally travelling or that slow down, serve as when braking is the role of storage power.
Because the drive system of automobile is regarded battery pack as single high-tension battery, all whole battery pack is carried out charging and discharging, so the performance of battery pack has determined the development of electric automobile at every turn.The batteries of electric automobile group is comprised of a plurality of square electric cell tandem stacks, connects after the parallel connection of battery core elder generation again, has improved performance and the connection reliability of battery pack.Because the quantity of battery core is many, for conserve space, adopts the mode of double layer design to be assembled into battery pack more.But cause the body after battery pack is assembled different owing to existing battery pack is subjected to the restriction in drive system of electric automobile space, do not have versatility.When using the battery pack of the electric automobile of some specific model on the automobile of other models, then can cause the space availability ratio of automobile driving system not enough, and then cause battery pack to tie up other spaces of electric automobile inside, bring obstruction for the global design of vehicle.Even the automobile that has just can adapt to after then must transforming the integral body of electric automobile, has caused waste to a great extent in order to use the battery pack of given shape.
The utility model content
The utility model will solve above-mentioned deficiency exactly, and a kind of versatility bilayer cells group that can adapt to various electric automobiles is provided.
In order to reach above-mentioned effect, it is a kind of for the bilayer cells group on the electric automobile that the utility model provides, the top cover, bottom and the square battery core that comprise battery pack, the upper and lower end face that the nonelectrode end of described side's battery core is fastened on interlayer forms double-deck battery core row, described interlayer is rectangle, and described double-deck battery core row's square battery core quantity is identical; Described double-deck battery core row's two ends is arranged with left side cover plate and right side cover plate, fixes by screw rod between described left side cover plate and the right side cover plate; The upper and lower end of left side cover plate and right side cover plate is affixed with described top cover, bottom respectively.
The preferred version of such scheme is that described bottom is provided with the auxiliary rib of the side that is connected them with the outside of interlayer.
The outside of described interlayer and bottom is affixed by screw rod.
The upper surface of described top cover is provided with n shape girth member, and the termination of girth member and described interlayer are fixed.Girth member is in order to make battery pack more stable, to have made things convenient for its resettlement, so its shape and quantity do not have special requirement, mainly deciding on the application of battery pack.
Because square battery core shell is metal, cause short circuit for fear of conducting electricity foreign material connection battery core shell and electrode, gap between described side's battery core is provided with heat insulating lamella, and the variable thickness of heat insulating lamella is installed the heat insulating lamella of different-thickness according to the size that the space is arranged more than between the square battery core.
The utility model is first take interlayer as benchmark, and in the card side of establishing, the square groove place in centre position, interlayer upper surface battery core, the electrode of square battery core up; The square battery core of as much is also placed in the lower surface of interlayer, the electrode of its side's battery core down, concrete square battery core is put sequence and is then looked the application of battery pack and determine that the space between the square battery core is filled up with heat insulating lamella.Again top cover and bottom are placed respectively double-deck battery core row's upper and lower end face, make reference column on top cover and the bottom corresponding with double-deck battery core row's location hole respectively on, and with the reference column thawing and fix.Two-layer battery core row's two ends is arranged with left side cover plate and right side cover plate, and the recess of left and right side cover plate is just in time clamped interlayer, will fix between left side cover plate and the right side cover plate by screw rod again, and two-layer battery core is arranged just in time jam-packed and fixing; The upper and lower end of left side cover plate and right side cover plate respectively with described top cover, bottom is affixed links into an integrated entity.The outside of described bottom and interlayer is provided with the auxiliary rib of side, and the auxiliary rib of side is fixed bottom and is connected with interlayer; Affixed by screw rod again between interlayer and the bottom.In order to make battery pack more stable, made things convenient for its resettlement, the upper surface of top cover is provided with n shape girth member, and the termination of girth member and described interlayer are fixed, and decide shape and the quantity of girth member according to the application of battery pack.
Bilayer cells group of the present utility model has been utilized the inner space of drive system of electric automobile well, has improved the space availability ratio of automobile, can not cause the waste of motor space and then reduces the transformation of electric automobile inside, has reduced the cost of electric automobile.
