[0002] The combination of batteries is generally connected in series and parallel by means of welding or screw fastening through the connecting piece to achieve the voltage and capacity of the application scenario. If the traditional connecting piece is welded, the single battery cannot be repaired and replaced. ;Using the screw fastening method, the battery pack is prone to series movement during long-term use, especially in vehicle applications, resulting in increased contact resistance or broken connections

Abstract
The invention relates to a battery combination connecting piece. The battery combination connecting piece is a connecting piece in series-parallel connection with positive and negative electrodes of abattery, the connecting piece is made of pure nickel, nickel plated iron or nickel plated copper, two holes are formed in the connecting piece according to the dimensions of terminals on the positiveand negative electrodes of a monomer battery, and the two holes are used for installing and fixing the terminals on the positive and negative electrodes respectively.
Description
technical field [0001] The invention relates to the field of chemical power sources, in particular to a battery combination connecting sheet. Background technique [0002] The combination of batteries is generally connected in series and parallel by means of welding or screw fastening through the connecting piece to achieve the voltage and capacity of the application scenario. If the traditional connecting piece is welded, the single battery cannot be repaired and replaced. ; Using the screw fastening method, the battery pack is prone to series movement during long-term use, especially in vehicle use, and the contact resistance increases or the connecting piece breaks. Using the above-mentioned traditional connecting piece to connect single cells in series and parallel, the single cells are all hard-connected. [0003] The invention provides a connecting sheet of a battery pack, which can realize soft connection between single cells. Contents of the invention [0004] Th...
