Problems solved by technology

However, the conductive wires are directly exposed to the outside. When the battery module packaging shell is not rigid enough and deforms, it will directly squeeze the conductive wires and cause the conductive wires to break or desolder, affecting the safety and stability of the battery module.

Abstract

The invention relates to a protective pressing plate and a battery module. The protective pressure plate includes: a main body of the pressure plate, which is in a strip structure. The main body of the pressure plate includes an upper surface and a lower surface opposite along the direction of its own thickness, and two sides opposite along the direction of its own width, at least a part of each side is sunken toward the centerline of the main body of the pressure plate , to form a protective recess, the maximum width of the upper surface of the main body of the pressing plate is greater than the maximum width of the lower surface. The protective pressing plate of the embodiment of the present invention can be used to fix the circuit board and protect the bonding wires, which improves the safety and stability of the battery module.

Description

technical field [0001] The invention relates to the technical field of batteries, in particular to a protective pressure plate and a battery module. Background technique [0002] With the development of technology, the application range of power batteries is becoming wider and wider, involving production or life. The power battery is also called a secondary battery, which is a rechargeable battery. Power batteries are widely used. Low-capacity traction batteries can be used for small electric vehicles, and high-capacity traction batteries can be used for large electric vehicles, such as hybrid electric vehicles or electric vehicles. When power batteries are used in groups, multiple power batteries are packaged to form a battery module. Two adjacent power batteries need to use bus bars to connect each power battery in series or in parallel. In addition, in order to keep the battery module lightweight, each power battery is electrically connected to external components thr...
