Battery connecting guide sheet

Abstract

A battery connecting guide sheet used for electrically connecting with a plurality of batteries, comprises a first sheetbody and a second sheetbody. The second sheetbody is attached on the first sheetbody and is physically and electrically connected with the first sheetbody. The second sheetbody is provided with a plurality of punched holes. The second sheetbody has larger conductivity and larger thickness than the first sheetbody, and the first sheetbody is physically and electrically connected with electrodes of the batteries. The battery connecting guide sheet formed by using mutual connection of two metal materials with different thickness and characteristics can effectively reduce the difficulty of welding the batteries and the guide sheet, and can allow a larger current in the processes of charge / discharge of batteries and facilitate rapid cooling in the processes of charge / discharge of batteries.

Description

technical field [0001] The invention relates to a battery connecting guide, in particular to a battery connecting guide made of two different materials. Background technique [0002] Batteries are generally used on mobile devices that are easy to carry. In order to make batteries with general capacity supply the power required by large mobile devices, such as electric vehicles, it is necessary to connect multiple batteries in series or in parallel to form a large battery. A battery module for charging and discharging current. Generally, one method of connecting batteries in series or in parallel is to use a connecting lead to bridge between the electrodes of two adjacent batteries, and use welding to connect the connecting lead and the plurality of batteries to form a current loop. [0003] Cooperate with reference Figure 8 , is a perspective view and a schematic diagram of the use of the existing battery connection guide. The material of the general battery 200 case (inc...

AI Technical Summary

Problems solved by technology

The main reason is that when the thickness of the connecting guide piece 100 increases, the current required for welding needs to be relatively larger, and the stress at the welding place also needs to be larger, which causes the difficulty of controlling the process parameters to increase, and the welding required The welding temperature is also difficult to concentrate due to the large heat dissipation area, which makes the welding quality difficult to control
