Abstract
The utility model provides a single-layer battery pack used on an electric automobile. The single-layer battery pack comprises a top cover, a bottom cover and a square electric core of the battery pack, wherein a square groove is formed in the upper end face of the bottom cover; the non-electrode end of the square electric core is clamped at the square groove to form an electric core bar; a left side cover board and a right side cover board are symmetrically arranged at two ends of the electric core bar; the left side cover board and the right side cover board are fixedly connected with each other through a screw; and the bottom cover is fixedly connected with the top cover through a side accessory. An elongated inner space of an electric automobile driving system is fully used, and the space utilization rate of the electric automobile is improved.
Description
Technical field
The utility model relates to battery pack, relates in particular to a kind of for the individual layer 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 parallel connection of battery core elder generation again, has improved performance and the connection reliability of battery pack.Because the limited space of automobile driving system mostly is a long and narrow rectangular space, but because the quantity of battery core is many, most of battery pack producer considers for global design, adopts the mode of double layer design to be assembled into battery pack more.But the battery pack of this double-deck stereo obviously can not satisfy the drive system of electric automobile of long and narrow space, if automobile must adopt double-deck vertical full battery pack, then can cause the drive system of electric automobile of this battery pack and this model not mate, just can adapt to after then needing the integral body of electric automobile transformed, caused 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.
The utility model content
The utility model will solve above-mentioned deficiency exactly, and a kind of individual layer battery pack that can adapt to the drive system of electric automobile of long and narrow space is provided.
In order to reach above-mentioned effect, it is a kind of for the individual layer battery pack on the electric automobile that the utility model provides, the top cover, bottom and the square battery core that comprise battery pack, described bottom upper surface is provided with square groove, the nonelectrode end of described side's battery core is fastened on described square groove place and forms battery core row, described battery core row's two ends are arranged with left side cover plate and right side cover plate, and are affixed by screw rod between described left side cover plate and the right side cover plate; Affixed by the auxiliary rib of side between described bottom and the top cover.
Described top cover and bottom are affixed with screw rod by the location hole on left side cover plate, the right side cover plate respectively.Avoided screw rod to contact with square battery core and insulated.
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 bottom as benchmark, in the card side of establishing, the square groove place in centre position, bottom upper surface battery core, the electrode of square battery core up, concrete battery core is put sequence and is then looked the application of battery pack and determine; Space between side's battery core is filled up with heat insulating lamella; Again top cover is placed battery core row's upper surface, make reference column on the top cover corresponding with location hole on the battery core row on, and with the reference column thawing and fix.Battery core row's two ends are arranged with left side cover plate and right side cover plate, the recess of left and right side cover plate just in time with the battery core row folding firmly, again by screw rod during with left side cover plate and right side cover plate row fix, battery core arranged just in time jam-packed and fix.Affixed by the auxiliary rib of side between bottom and the top cover, in order further to strengthen the steadiness of battery pack, the outside of its top cover and bottom is affixed by screw rod.
Individual layer battery pack of the present utility model has been utilized the inner space of sleeve configuration 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.
