Abstract

The invention discloses a combined connection device for batteries, which comprises a plurality of batteries and connecting parts which are respectively connected with the ends of each battery. The connection device also comprises a plurality of conductive connection units and conductive parts; wherein, the number of the conductive connection units is equal to that of the batteries; the conductive parts are electrically connected with the conductive connection units; and the conductive connection units correspond to the batteries one by one and are electrically connected to the connecting parts. The invention replaces the welding process in the battery combination, simplifies the battery combination process, facilitates the disassembly of one battery, and also ensures the reliability of the battery combination.

Description

technical field [0001] The invention relates to a combined connection device for batteries. Background technique [0002] When multiple batteries are connected in series and parallel, the multiple batteries are usually fixed and electrically connected by welding to form a battery pack. Once such a battery pack is welded, it is difficult to disassemble. When individual batteries in the battery pack are damaged, it cannot Separate disassembly and replacement requires the entire battery pack to be scrapped, resulting in high maintenance costs. In order to solve this problem, the applicant of the present application has applied for a patent for a freely detachable battery assembly device. The two ends are respectively provided with accommodating grooves embedded and electrically connected with the positive and negative terminals of the battery. The elastic piece, when the two connecting units are plugged and fixed, the metal elastic pieces on the adjacent surfaces contact and ...
