Preferably, said electrode keyset is provided with at least two column electrode sheets along its length, wherein, has at least delegation's electrode slice to be divided into some electrode connecting piece.

Preferably, said electrode connecting piece offers two electrode ports.

Preferably, two electrode ports offering on described each electrode slice are lined up two row of rule on the keyset length direction.

Preferably, a said side that is divided into the electrode slice of some electrode connecting piece also is provided with parallel with it electric connection bar, links together with fuse between said electric connection bar and each electrode connecting piece.

Preferably, said the two poles of the earth with all batteries that are connected in parallel in the battery pack after the assembling of electrode keyset all lead to holding wire, and said holding wire has been made into the standard winding displacement on the printed circuit board (PCB).

Preferably, be coated with the tin layer on the said electrode slice that is not divided into some electrode connecting piece.

Preferably, rely on double-screw bolt and nut to link together between said cell and the electrode keyset.

Compared to prior art, the utlity model has following advantage:

1) avoids the lead between each cell to connect, prevented accidents such as misconnection, broken string even accidental short circuit;

2) rely on double-screw bolt and nut to link together between cell and the electrode keyset, thus the whole steadiness that has improved battery pack;

3) the tin layer that applies on the electrode slice of electrode connecting piece helps to improve the electric conductivity of battery set electrode;

4) fuse can be brought into play protective effect to batteries in parallel connection.

[embodiment]

Below in conjunction with the accompanying drawing illustrated embodiment the utility model is described further.

Please refer to shown in the accompanying drawing 1 to 3; Be connected with electrode keyset (10,20) on the two poles of the earth of thebattery pack 30 that the utility model is related respectively;Battery pack 30 comprises five crosstalk ponds; Be connected in parallel between sevencells 40 in wherein every string, be cascaded between every two adjacent crosstalk ponds.

Electrode keyset 10 is provided with triplex row electrode slice (11,12,13) along its length; Wherein, There are two column electrode sheets (11,12) to be divided into sevenelectrode connecting piece 14; Eachelectrode connecting piece 14 offers twoelectrode ports 141, and like this, describedelectrode ports 141 is lined up two row of rule onkeyset 10 length directions.

A said side that is divided into the electrode slice (11,12) of someelectrode connecting piece 14 also is provided with parallel with itelectric connection bar 15; Saidelectric connection bar 15 and each electrode connecting piece link together withfuse 16 between (11,12); In the utility model; Saidfuse 16 can adopt enclosed fuse, and fuse is used for the cell of protecting batteries in parallel connection to be short-circuited.
