Abstract
The utility model relates to a square sealed battery unit for an electric vehicle. The square sealed battery unit is characterized by comprising a battery unit, wherein the battery unit is formed by a plurality of battery cells which are arranged in parallel, wherein an insulation partition plate is arranged between the adjacent battery cells; insulation end plates are arranged on the two ends of the battery unit; pressure plates are fixed on the two sides of the battery unit; a bottom plate is fixed on the bottom end of the battery unit; and the battery cells are connected in series by a connecting sheet. The square sealed battery unit adopts a framework structure, has a compact structure, small occupied space and high shock resistance performance. The compact structure reduces the distance between positive and negative electrodes; moreover, radiation holes are formed on the insulation partition plates, so that a radiation effect is improved, and performance is improved and the service life of the battery cells is prolonged.
Description
Technical field
The utility model relates to a kind of square sealed cell group for electric motor car.
Background technology
At present, the battery pack that electric motor car uses, the shortcoming such as it is not compact to exist structure, and it is large to take up room, and heat dispersion is bad, and the heat that battery pack produces in charge and discharge process can't evenly distribute, and has affected the performance and used life of battery.
The utility model content
According to above deficiency of the prior art, the technical problems to be solved in the utility model is: a kind of defects that solved is provided, and simple in structure, battery composite structure is compact, the square sealed cell group of good heat dissipation effect.
The technical scheme that its technical problem that solves the utility model adopts is: described square sealed cell group, it is characterized in that: comprise battery pack, battery pack is comprised of a plurality of cells that are arranged side by side, be provided with insulating barrier between the adjacent cell, the two ends of battery pack are provided with insulating end plate, the both sides of battery pack are fixed with pressing plate, and the bottom of battery pack is fixed with base plate, is connected in series by brace between the cell.
Have louvre on the described insulating barrier.
Described battery pack is comprised of 8 ~ 10 cells that are arranged side by side.
The beneficial effect that the utility model has is: square sealed cell group has adopted tower structure, compact conformation, and it is little to take up room, and anti-seismic performance is high; Cramped construction has reduced distance between the both positive and negative polarity, and has louvre on the insulating barrier, has improved radiating effect, has improved the performance and used life of battery.
Description of drawings
