Problems solved by technology

However, considering that the battery connection device is only connected in series in the axial direction and in parallel in the circumferential direction, it limits the series-parallel connection of battery packs and needs further improvement. It can be easily assembled and disassembled for each battery cell, and it is compact and convenient to connect.

Abstract

The invention provides a battery connecting device, which is used for connection of many battery monomers, and the apparatus comprises a connecting block prepared by insulating material and installed on the terminal of the battery monomer and a conducting strip for electric connection. The invention has the advantages of compact structure and convenient connection, thereby each monomer battery is connected in series or in parallel connection on the same plane with series-parallel flexibility and free degrees of space arrangement, and the welding connection between electrodes and the assembly fixation between batteries of the assembled battery composed by connection are not needed. The invention not only can be operated conveniently, safely and reliably, but also can be combined at will for realizing circumferential serial connection and series-parallel and parallel electrical connection structures, and satisfying voltage and capacity demands of various storage batteries and batteries.

Description

technical field [0001] The invention belongs to the technical field of conductive connection of battery cells, and in particular relates to a battery connection device of a power supply device used in hybrid electric vehicles, electric vehicles and the like. Background technique [0002] The battery is a power source with a wide range of uses. Generally, according to the voltage and capacity requirements of the load, multiple single cells are combined in series and parallel. The voltage is increased through series connection, and the capacity is increased through parallel connection. The current method is to first connect a certain number of single cells with a bus bar to connect all the positive electrodes together, and then use another bus bar to connect all the negative electrodes together, thus forming a parallel branch. Connect the single cells corresponding to the same position in multiple parallel branches according to the order of positive and negative electrodes to...
