Description
Technical field
The utility model relates to a kind of Lead Acid Battery Used for Electric Vehicle.
Background technology
Lead Acid Battery Used for Electric Vehicle inside has comprised a plurality of cells that are cascaded, respectively be provided with parallel relative positive negative bus on the both positive and negative polarity group who forms by the polylith pole plate of each cell, as shown in Figure 1, respectively there is one to be used for and the outside output 1 that is connected on the positive negative bus, two outputs 1 are on the same horizontal linear, and therefore two outputs are relatively positive.Because the both positive and negative polarity group is immersed in the electrolyte, and separated by electrolysis, so the positive resistance minimum of negative bus between two outputs 1, increase gradually in local resistance away from two outputs 1, CURRENT DISTRIBUTION when work in the storage battery pond on the positive negative bus is inhomogeneous, as shown in Figure 2, the electric current between the output 1 is comparatively concentrated, and it is comparatively sparse to be distributed in the electric current at all the other positions of bus-bar.The strong and weak utilance that directly influences active material on the pole plate of electric current, because the electro-chemical reaction difference at each position is very big in the utmost point group galvanization, cause the active material excess load utilization of the big pole plate of CURRENT DISTRIBUTION, plate active material is overcharged, shortened the useful life of pole plate; The less utilization of the plate active material that CURRENT DISTRIBUTION is little makes plate active material owe to fill, and the long-term back plate active material electro-chemical reaction that uses is degenerated the generation that causes not depositing electrical phenomena.This drawbacks limit of storage battery has also reduced the service behaviour of pole plate, shortens the useful life of storage battery.
The utility model content
The technical problems to be solved in the utility model provides a kind of Lead Acid Battery Used for Electric Vehicle, and utmost point group structure is reasonable in design, and the resistance between positive each position of negative bus is identical.
For solving the problems of the technologies described above, the utility model adopts following technical scheme: this Lead Acid Battery Used for Electric Vehicle comprises housing and loam cake, described loam cake is installed in housing top, this enclosure interior is provided with the cell of several series connection, described cell inside is provided with anodal group and negative pole group, described anodal group is provided with positive bus, described negative pole group is provided with negative bus-bar, described positive bus is parallel with negative bus-bar relatively, described positive bus is provided with and is used for being connected with the adjacent monomer battery or the cathode output end of output voltage, described negative bus-bar is provided with and is used for being connected with the adjacent monomer battery or the cathode output end of output voltage, and described cathode output end staggers relative with cathode output end.
As a kind of improvement of the present utility model, described loam cake bottom is provided with corresponding cell and is used to hold the groove of cathode output end and cathode output end.
The utility model adopts technique scheme, utmost point group structure is reasonable in design, the output end position of positive negative bus is optimized, resistance between positive each position of negative bus is identical, CURRENT DISTRIBUTION is even during work, and utmost point group goes up all pole plate electro-chemical reaction unanimities, and each plate active material utilance is identical, and then given play to the service behaviour of pole plate maximum, promote the storage battery overall performance; Evenly utilize each pole plate in the utmost point group, make pole plate ILS, the prolongation of the life-span of storage battery like this.
