Abstract

The utility model relates to a large-capacity battery combination module. The battery combination module is composed of a plurality of individual batteries which are arranged longitudinally and transversely to form a battery pack; all the individual batteries are connected through welding by means of conductive pieces; busbars are arranged at the end portions of the battery combination module and a plurality of main positive and main negative leading-out ends are arranged on the busbars; the front side and the rear side of the battery pack are clamped through clamping plates made of an insulating fire retardant material; a plurality of lug bosses for clamping and fixing the respective individual batteries in the battery pack are arranged on the clamping plates; a plurality of counter bores for fastening are formed at the side edges of the clamping plates, and through holes for heat dissipation are formed on the rear surfaces of the clamping plates in positions corresponding to the lug bosses; and end plates ensuring insulation of the busbars from other parts are arranged outside the busbars. The utility model is a large-capacity battery combination module which is provided with a plurality of main positive and main negative leading-out ends, and is excellent in electrical properties, simple in structure, easy to implement, convenient to use, excellent in structural stability, firm and durable, good in heat dissipation effect, flame retardant, and insulated.

Description

A kind of high capacity cell composite module

Technical field

The utility model relates to a kind of high capacity cell composite module.

Background technology

The general combined method of high capacity cell composite module is: at first the cell with some carries out parallel connection according to certain permutation and combination rule, reaches required capacity requirement; And then with several such and joint group is together in series, reach required voltage request.

And if the positive and negative exit of joint group confluxes too concentratedly, then the pressure drop in the shunt circuit just can not be ignored, this can cause on the one hand and joint group in each battery discharge unbalanced, also can very high requirement be proposed on the other hand to the ampacity of shunt circuit lead.Therefore high capacity cell parallel connection composite module positive and negative drawn the whether scientific and reasonable performance that will directly have influence on the electric property of whole battery group of setting.

The utility model content

The utility model provides a kind of high capacity cell composite module, and purpose provides a kind of high capacity cell composite module, and this battery compound module has a plurality of exits of always just, always bearing; Electric property is good, and is simple in structure, easy to implement; Easy to use, have good structural stability, sturdy and durable; Good heat dissipation effect, fire-retardant, insulation.

For addressing the above problem; The utility model adopts following technical scheme: battery compound module is permutated and combined as battery pack in length and breadth by several cells (5); Adopt conducting strip (2) to be welded to connect between each cell (5); The battery compound module end is provided with bus-bar (3), and a plurality of exits of always just, always bearing are arranged on the bus-bar (3); Side is through clamp (1) clamping of insulation fire proofing before and after the battery pack; On clamp (1), be provided with the boss of some each cells of battery pack (5) that are used for being fixedly clamped; Be provided with some fastening counter sinks that can be used at clamp (1) side, clamp (1) back side is provided with the through hole that can be used for dispelling the heat in the position of corresponding boss; Bus-bar (3) outside is provided with the end plate (4) that insulate between assurance bus-bar and other parts.

Base plate between clamp (1) convex platform and the boss is provided with the perforate of convenient welding.

Clamp (1) go up in order to draw total just or total negative side be provided with fixed side, fixed side is provided with fixing hole, fixing hole fixed-conductive film (2) and bus-bar (3).

Conducting strip (2) is gone up and is provided with exterior open cell with the corresponding position of clamp (1) boss.

The advantage of the utility model has: 1, make the battery pack process of assembling simple to operate, safe and reliable;

2, have good structural stability, sturdy and durable, good heat dissipation effect, fire-retardant, insulation.

3, the present invention has good electric property.

Embodiment

Shown in Fig. 1-5; Battery compound module is permutated and combined as battery pack in length and breadth by several cells (5); Adopt conducting strip (2) to be welded to connect between each cell (5), the battery compound module end is provided with bus-bar (3), and a plurality of exits of always just, always bearing are arranged on the bus-bar (3); Side is through clamp (1) clamping of insulation fire proofing before and after the battery pack; On clamp (1), be provided with the boss of some each cells of battery pack (5) that are used for being fixedly clamped; Be provided with some fastening counter sinks that can be used at clamp (1) side, clamp (1) back side is provided with the through hole that can be used for dispelling the heat in the position of corresponding boss; Bus-bar (3) outside is provided with the end plate (4) that insulate between assurance bus-bar and other parts.

At first the boss on the perforate alignment clamp of conducting strip is tiled on the clamp; Cell with some is emitted between the boss of clamp then; Again other one group of clamp conducting strip assembly parts are buckled in the other end of battery; Use bolt that battery module is fastening then, the perforate that sees through between the clamp convex platform is welded.Re-use bus-bar and compress on the fixing hole that conducting strip is fixed on the clamp side plate, end plate is installed at last.

This battery compound module electric property is good, simple in structure, easy to implement, easy to use, has good structural stability, and is sturdy and durable, fire-retardant, insulation, good heat dissipation effect.

Obviously, the foregoing description of the utility model only be for explain clearly that the utility model does for example, and be not to be qualification to the execution mode of the utility model.For the those of ordinary skill in affiliated field, on the basis of above-mentioned explanation, can also make other multi-form variation or change.Here can't give exhaustive to all execution modes.(such as parameters such as partial structurtes, description of materials, sizes) conspicuous variation that every technical scheme that belongs to the utility model is extended out or change still are in the row of the protection range of the utility model.
