Abstract
The utility model provides a lithium ion battery pack. The battery pack is formed through series connection and parallel connection of a plurality of battery cells, wherein the distribution area of the battery cells in the battery pack is concave; a sunk part is formed on one side of the battery pack; a protective circuit board is arranged in the sunk part; a cushion is arranged between the bottom surface of the protective circuit board and the battery pack; the surface of the protective circuit board is flush with the side of the battery pack; insulation boards are arranged between the two sides of the protective circuit board and the battery pack. The battery pack has the beneficial effects that the battery cells and the protective circuit board are distributed reasonably, so that the space utilization rate is higher and the volume of the battery pack can be smaller; besides, the size of the sunk part can be set according to the size of the protective circuit board, and as the protective circuit board is protected by the cushion and the insulation boards in the sunk part, the circuit structure of the protective circuit board is safer.
Description
Technical field
The utility model relates to lithium ion battery group.
Background technology
Lithium ion battery group is to be generally formed by connecting by series and parallel connections by multiple cells.Between cell, form the external shape of whole lithium ion battery group by mutually boning; the external shape of the battery pack on existing market is of all kinds; but be all generally the master that is shaped as who takes rule; although the battery shapes profile of this regular shape is good-looking; but be not optimum distribution form to the utilance in space; because need to add protective circuit plate toward contact in battery pack; the battery shapes that membership causes former this rule that adds of this protective circuit plate becomes irregular; when after battery pack cover upper shell, can make battery pack take larger space.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of lithium ion battery group, and the distribution of battery and protective circuit plate is reasonable, and space availability ratio is higher, and the volume of battery pack can do littlely.
For solving the problems of the technologies described above; the technical solution of the utility model is: a kind of lithium ion battery group; described battery pack is formed by series and parallel connections by some cells; in described battery pack, the distributed areas of cell are spill; and form depression in a side of battery pack; in described depression, be provided with protective circuit plate; between described protective circuit plate bottom surface and battery pack, be provided with cushion pad; protective circuit plate surface is concordant with battery pack side, between the both sides of protective circuit plate and battery pack, is provided with insulation board.The distribution of the utility model cell and protective circuit plate is reasonable, and space availability ratio is higher, and the volume of battery pack can do littlely.In addition, the size of depression can be set according to the size of protective circuit plate, and protective circuit plate is subject to the protection of cushion pad and insulation board in depression, and its circuit structure can be safer.
As improvement, the cross section quadrate of described battery pack.
As improvement, the height of described battery pack equates with the height of a cell.
As improvement, described battery pack is distributed with four row batteries in concave regions, and first, fourth row battery has four, and second and third row battery has three.
As improvement, the material of described cushion pad is EVA.
The beneficial effect that the utility model compared with prior art brought is:
The distribution of the utility model cell and protective circuit plate is reasonable, and space availability ratio is higher, and the volume of battery pack can do littlely.In addition, the size of depression can be set according to the size of protective circuit plate, and protective circuit plate is subject to the protection of cushion pad and insulation board in depression, and its circuit structure can be safer.
Accompanying drawing explanation
Fig. 1 is the utility model vertical view.
Fig. 2 is the utility model front view.
Embodiment
Below in conjunction with Figure of description, the utility model is described in further detail.
As shown in Figure 1, 2, a kind of lithium ion battery group, described battery pack 1 is formed by series and parallel connections by some cells 2, and the cell 2 of the present embodiment is seven strings two syndetons also; In described battery pack 1, the distributed areas of cell 2 are spill, described battery pack 1 is distributed with four row batteries in concave regions, first, fourth row battery has four, second and third row battery has three, the height of described battery pack 1 equates with the height of a cell 2, thereby the side in battery pack 1 forms depression, and the degree of depth of this depression is equivalent to the diameter of a cell 2, and length is equivalent to the length of a cell 2.In described depression, be provided with protective circuit plate 4, protective circuit plate 4 has been filled depression, makes the cross section quadrate of whole battery pack 1.Between described protective circuit plate 4 bottom surfaces and battery pack 1, being provided with material is the cushion pad 6 of EVA, and protective circuit plate 4 surfaces are concordant with battery pack 1 side, are provided with insulation board 3,5 between the both sides of protective circuit plate 4 and battery pack 1.After installing, protective circuit plate 4 by strap, itself and battery pack 1 are bundled.The utility model cell 2 is reasonable with the distribution of protective circuit plate 4, and space availability ratio is higher, and the volume of battery pack 1 can do littlely.In addition, the size of depression can be set according to the size of protective circuit plate 4, and protective circuit plate 4 is subject to the protection of cushion pad and insulation board in depression, and its circuit structure can be safer.
Claims (5)
