Description
Technical field
The present utility model application belongs to assembled battery accessory technical field, in particular to a kind of assembled battery welding piece.
Background technique
At present both at home and abroad in entire cylindrical power battery combination field, the overwhelming majority is all folded using copper sheet+nickel sheet
The assembled battery welding piece or (such as: 18650,26650,21700 is round as assembled battery welding piece using pure nickel piece that weldering is constituted
Cylindrical battery combination)；Although pure nickel piece is not a problem (such as electric bicycle for the battery pack cooperation connection of thin electric current charge and discharge
Spcific power battery pack), but copper sheet+nickel sheet stitch welding composition assembled battery welding piece is used for the power electric of high current charge-discharge
Pond group can have several aspects as connection sheet (such as: electric car class, energy storage cabinet class reserve battery group):
1. the big manufacturing cost of the valuable dosage of copper sheet is higher, compared with conventional fuel oil class automobile, there is no clear superiority in price；
It, can be higher if adding coating cost on copper sheet surface 2. copper sheet surface is easy to oxidize；
3. copper sheet density ratio is great, the own wt of battery pack can be greatly increased, equal to increasing electric vehicle own wt,
Higher energy consumption will be will lead to, be equivalent to the capacity for reducing battery pack.
