Abstract
The utility model relates to a unit cell with positive, negative pole post, comprising a plurality of monomer cells. The utility model is characterized in that a nut cap of the monomer battery is fixedly connected with a positive pole column, and the bottom of the housing of the monomer battery is fixedly connected with a negative pole column; six nickel-hydrogen monomer cells are in series connected as a unit cell by a connecting assembly. A plurality of monomer cells composes a combined drive automobile-used battery group. The utility model has the advantages that the varying element of rubber ball discharging pressure inside the nut cap caused by overheated welding can be removed at the root, and the evenness of the battery discharging pressure can be further improved, thereby, the charging, discharging electricity capability of the nickel hydrogen battery group under high power is further improved.
Description
Technical field
The utility model relates to a kind of assembled battery, is specifically related to be used for a kind of element cell that has positive and negative pole of hybrid vehicle.
Background technology
The conventional automobile-used high-capacity nickel-hydrogen battery group of hybrid electrically is also often used the element cell that has positive and negative pole to be connected in series and is formed.But the method for welding pole is: utilize electric resistance welding or other similar welding methods after the battery moulding again, nut of welding or double-screw bolt on the positive pole block of a cell, double-screw bolt of shell bottom welding or nut at the another cell, utilize nut and double-screw bolt that cell is together in series then, realize that the high power of battery discharges and recharges.Part is but this connected mode comes with some shortcomings, and the battery cap after the welding can not carry out the check of exhaust pressure again.If overheated when so in a single day welding, will cause the variation of the ball exhaust pressure that block is inner, this variation can not in time detect again, thereby causes the performance difference between the cell.
Summary of the invention
The purpose of this utility model provides a kind of element cell that has positive and negative pole, it can reduce the variation of the inner ball exhaust pressure of cell block, and can carry out the check of exhaust pressure to cell, make every cell exhaust pressure basic identical.
A kind of element cell that has positive and negative pole described in the utility model comprises many cells, it is characterized in that: be fixedly connected with a positive terminal on the block of cell, be fixedly connected with a negative terminal in the bottom of cell; With nut and brace many cells are connected to element cell.Positive and negative pole can utilize copper, iron or silver-plated copper, the iron of nickel plating.Because positive and negative terminals is to be welded on the block of cell in advance respectively and the bottom, so, can get rid of because of welding the overheated changing factor that causes the ball exhaust pressure of the inside of blocking a shot, make every cell exhaust pressure basic identical.
Described a kind of element cell that has positive and negative pole is composed in series by connector by 6 ni-mh cells.The battery pack that can form Hybrid Vehicle with a plurality of element cells.
The utility model is compared with prior art and is had the following advantages: fundamentally got rid of because of welding the overheated changing factor that causes the ball exhaust pressure that block is inner, further improve the uniformity of cell row atmospheric pressure, thereby further improved the charge and discharge performance of Ni-MH battery group under high power conditions.
Description of drawings
Fig. 1 is the structural representation of cell.
Fig. 2 is the local enlarged diagram at the A place of Fig. 1.
Fig. 3 is the local enlarged diagram at the B place of Fig. 1.
Embodiment
Below in conjunction with accompanying drawing structure of the present utility model is further described.
Referring to Fig. 1, Fig. 2 and Fig. 3, positive terminal 3 is welded on the block 2 earlier, negative terminal 4 is welded on the bottom of cell housing, makes element cell 1 again, so just can fundamentally get rid of because of welding the overheated changing factor that causes the ball exhaust pressure that block is inner.Fundamentally got rid of because of welding the overheated changing factor that causes the ball exhaust pressure that block is inner, then, with connector 56 ni-mh cells have been composed in series element cell and get final product.The battery pack of again a plurality of element cells being formed Hybrid Vehicle.
