Abstract

The utility model discloses a connecting device helping a power battery pack achieve high-rate discharge. The device comprises single batteries, a fixing frame, a series connection device and a parallel connection device. Inserting grooves for positive terminals of the single batteries to be inserted are arranged at the back of the fixing frame, through holes are arranged at the bottoms of the inserting grooves, limiting blocks are arranged at gaps between the through holes, air holes passing through the fixing frame are arranged in the center of the limiting blocks, and dovetails and dovetail grooves are arranged on the periphery of the fixing frame. One end of the series connection device is welded with positive caps of the batteries, and clamping jaws for clamping negative terminals of the batteries are arranged at the other end of the series connection device. Holes are arranged on the parallel connection device to correspond to the welding ends of the positive poles of the batteries on the series connection device, and limiting holes are arranged at positions corresponding to the limiting blocks of the fixing frame. The dovetails and the dovetail grooves facilitate assembly with another fixing frame.

Description

A kind of jockey that helps power battery pack to realize high-multiplying power discharge

Technical field:

The utility model relates to electrokinetic cell combination jockey, is specially adapted to the high-multiplying power discharge power battery pack and uses.

Background technology:

Large-capacity battery pack generally is that capacity requirement is satisfied in a plurality of cell parallel connections at present; Connect again after also need electric current being compiled after the parallel connection and satisfy voltage requirements; Owing to so the requirement that need conflux to the collector-shoe gear current capacity will increase along with battery capacity; This has just limited the increase of battery pack scale, in the process of confluxing, also can slattern more energy with the form of resistance heat simultaneously.

Summary of the invention:

The task of the utility model is to propose a kind of power battery pack that helps to be easy to realize high-multiplying power discharge, reduces the production cost of battery pack, is easy to the high-multiplying power discharge electrokinetic cell combination jockey of the modularization batch process of the standard that realizes.The task of the utility model is to accomplish like this; Comprise cell, it is characterized in that: the battery combination jockey is made up of fixed mount, tandem arrangement and shunting means, and the said fixed mount back side can supply to insert the slot of cell positive terminal; The bottom surface of said slot is provided with through hole; The gap location of said through hole is a guide vane end stop, and there is the air-vent that runs through said fixed mount in said guide vane end stop central authorities, is provided with dovetail and dovetail groove around the said fixed mount;

Said tandem arrangement one end and the welding of anode block have the claw that clamps the GND end on its other end;

It is corresponding that said shunting means is provided with on perforate and the said tandem arrangement anode welding ends, and the corresponding position of said fixed mount guide vane end stop has spacing hole.

The above dovetail and dovetail groove of said fixed mount is convenient and another fixed mount assembly unit, the above claw of said tandem arrangement be can bending forming flexure strip.

The bore dia that said shunting means is provided with is greater than the guide vane end stop on the fixed mount, and the spacing hole diameter that open said guide vane end stop position is greater than said tandem arrangement and anode welding ends.

Said fixed mount is made by the insulation fire proofing, and said tandem arrangement is to be made by the high resiliency conductive metal thin plate, and said shunting means is to be made by conductive metal thin plate.The utlity model has following effect: use the interior main current loop of power battery pack of said jockey to be the series loop between battery; Reduced collector-shoe gear; This moment, the effect of each cell in balanced and the joint group was only played in the shunt circuit, thereby can be so that power battery pack is easy to realize high-multiplying power discharge; Owing to reduced collector-shoe gear, and collector-shoe gear generally adopts expensive high conductivity metal, so jockey can reduce the production cost of battery pack greatly; Because what GND adopted is the assembled syndeton, avoided because spot welding and to the damage of cell; The battery pack process of assembling also becomes simply simultaneously, and the modularization that is easy to the standard that realizes produces in batches.
