Description
Technical field
The utility model relates to a kind of battery, especially relates to a kind of power battery pack.
Background technology
Along with serious day by day with environmental pollution of petering out of fossil energy, new forms of energy more and more receive people's attention, and particularly the lithium-ion-power cell development in recent years is rapid for electrokinetic cell.Along with the development of the big force urges electric automobile of national governments, a large amount of electrokinetic cell manufacturing enterprises emerge in large numbers, and industry development is in the ascendant.
Electrokinetic cell, particularly light-duty electrokinetic cell, generally square or cylindrical single the battery cell by certain size carries out parallel connection or series connection, and then the board-like material of externally wrapping one deck and have certain intensity is combined into the power battery pack of a fixed structure.In the available dynamic battery product; Generally adopt the critical piece of the rigid board-like material of multi-disc plastic plate or multi-disc as power battery pack; The cost of this multi-disc plastic plate or multi-disc hard plate-shaped material has occupied certain proportion in the total cost of production of battery; And the structural design of such electrokinetic cell is reasonable inadequately.
Electrokinetic cell of the prior art mainly adopts is that the scheme of epoxy plate assembly unit is made, and the cost of such electrokinetic cell is higher, has seriously restricted the electrokinetic cell competitiveness of product.Meanwhile; Owing to adopted the multi-disc board-like material to carry out assembly unit; Need carry out the additional processing of positions such as interface holes, side cut to single piece plate, make long processing time, producing cost is bigger; Add the expensive of epoxy sheet material self, this has just caused the production cost of present electrokinetic cell higher.In addition, electrokinetic cell needs the battery case of piecemeal assembly unit battery in carrying out last battery pack assembling process, and work efficiency is slow, and production efficiency is low, is unfavorable for the production in enormous quantities of electrokinetic cell.
The utility model content
The purpose of the utility model is to overcome the above-mentioned deficiency that exists in the prior art, and a kind of reasonable in design is provided, dependable performance, and production cost is low, and is easy to manufacture, the power battery pack that production efficiency is high.
The utility model addresses the above problem the technical scheme that is adopted: this power battery pack comprises cell body and lead, and said cell body comprises several battery cells, series connection and/or parallel connection each other between these several battery cells; Said lead is connected on the cell body; Its characteristics are: said power battery pack also comprises housing, and said housing is an integral structure, and this housing is provided with wire guide; Said cell body is installed in the housing, and said lead cross-under is in the wire guide of housing.
The said housing of the utility model is cuboid or square body structure.
The quantity of battery cell is between 2-10 in the said cell body of the utility model.
The material of the said housing of the utility model is plastic plate material or paper-board material or paper composite plate material or composite glass fiber sheet material matter or composite stone cotton board material matter.
The utility model compared with prior art has the following advantages and effect: simple in structure, reasonable in design, and dependable performance, easy to manufacture, production cost is low.Adopt the housing of integrated molding in the utility model, help simplifying production technology, increase work efficiency.
