Output uses Five-channel shunting mode, draws in the form of dynamic wire harness as positive and negative anodes, and low voltage connector 5 is exported as data
End.
The mode of lateral connection is used in series between mould group, battery modules 3 of the present invention are set as 13, and piece 13 is connected in series and makees
For the total positive output of rear end mould group, it is fixedly connected by nut with the self-clinching standoff on confluence aluminium row 11；Piece 14 is connected in series to make
For the total negative output of rear end mould group, it is fixedly connected by nut with the self-clinching standoff on confluence aluminium row 11；Piece 15 is connected in series to make
It connects and transfers for upper and lower level, be fixedly connected by nut with the self-clinching standoff on confluence aluminium row 11；16 conduct of piece is connected in series
Realize the series connection piece between equidistant arrangement module, it is same to connect by the way that the self-clinching standoff on nut and confluence aluminium row 11 is fixed
It connects.And the series connection between more remote mould group is then carried out by fuse 18 across remote series connection and circuit using series connection piece 17
Protection.Piece 19 is connected in series and is used as the total positive output of front end module, is fixed by nut and the self-clinching standoff on confluence aluminium row 11
Connection；Piece 20 is connected in series and is used as the total negative output of front end module, is fixed by nut and the self-clinching standoff on confluence aluminium row 11
Connection；It connects between three mould groups that front end module is included and is equally carried out using piece 16 is connected in series.Front end module is always born defeated
It carries out being forwarded to current divider 22 by connection sheet 21 out, then total negative confluence copper sheet 23 is forwarded to by current divider 22, install total negative
