Description
Technical field
The utility model relates to battery pack, relates in particular to a kind of for the double-deck trapezoidal battery pack 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 first parallel connection of square battery core again, has improved performance and the connection reliability of battery pack.Because the quantity of square 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 double-deck trapezoidal battery pack of versatility that can adapt to various electric automobiles is provided.
In order to reach above-mentioned effect, it is a kind of for the double-deck trapezoidal battery pack 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 upper strata battery core row and the battery core row of lower floor, described interlayer is trapezoidal, and upper strata battery core row's square battery core quantity is less than the battery core row's of lower floor square battery core quantity; Described upper strata battery core row is arranged with respectively left side cover plate and right side cover plate with the battery core row's of lower floor two ends, fixes by screw rod between described left side cover plate and the right side cover plate; The two ends of described interlayer are affixed by screw rod with described top cover, bottom respectively.In order to insulate, in the location hole on the left of the screw rod of connection top cover and bottom is provided in a side of on cover plate and the right side cover plate, avoided it to contact with square battery core.
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 interlayer outside.
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 side of placement, the lower surface battery core of interlayer, the electrode of its side's battery core down, upper strata battery core row's square battery core quantity is less than the battery core row's of lower floor square battery core quantity, and concrete square battery core is put sequence and 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 upper strata battery core row's upper surface, the battery core row's of lower floor lower surface, make on top cover and the bottom reference column respectively with upper strata battery core row, the battery core row of lower floor on location hole corresponding on, and with the reference column thawing and fix.Upper strata battery core row is arranged with respectively left side cover plate and right side cover plate with the battery core row's of lower floor two ends, fixes by screw rod between left side cover plate and the right side cover plate, and two-layer battery core is arranged just in time jam-packed and fixing; The two ends of described interlayer is affixed by screw rod with described top cover, bottom respectively.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.
Double-deck battery core row also can only install amber layer battery core row in the utility model, and its upper strata battery core row do not install, and then becomes the compact battery group of individual layer, can carry out according to actual needs conversion like this, and its application is more extensive, flexible.
The trapezoidal battery pack of bilayer of the present utility model has been utilized the inner space of drive system of electric automobile well, improved the space availability ratio of automobile, can not cause the waste of motor space and then reduce the transformation of electric automobile inside, reduce the cost of electric automobile.
