Abstract

The invention discloses a light composite explosion-proof cover plate for power batteries. The light composite explosion-proof cover plate comprises a cover plate body, an anode connecting column, a cathode connecting column, an anode connecting sheet and a cathode connecting sheet. The anode connecting column and the cathode connecting column are positioned on the front surface of the cover plate body, and the anode connecting sheet and the cathode connecting sheet are positioned on the back surface of the cover plate body and are riveted with the anode connecting column and the cathode connecting column; the cover plate body comprises an aluminum plate and a magnesium alloy plate, and the aluminum plate is coated on the outer surface of the magnesium alloy plate; the thickness of the magnesium alloy plate accounts for 1/2-2/3 of the thickness of the cover plate body; an explosion-proof device is welded in the middle of the cover plate body. The light composite explosion-proof cover plate for the power batteries has the advantages that the magnesium alloy plate and the aluminum plate are subjected to composite rolling to obtain the cover plate body, the weight of the cover plate body can be reduced, the anti-vibration performance of the cover plate body can be improved, accordingly, excellent anti-vibration protection can be provided for the batteries, and the light composite explosion-proof cover plate is excellent in comprehensive performance and has a broad market prospect.

Description

technical field [0001] The invention relates to the technical field of power battery cover plates, in particular to an explosion-proof light-weight composite power battery cover plate. Background technique [0002] The power battery is the power source that provides the power source, and mostly refers to the battery that provides power for electric vehicles, electric trains, electric bicycles, and buses. Power batteries are generally packaged in aluminum shells, which have the characteristics of small size, light weight, strong power, no memory, and environmental protection, and have been widely used at present. [0003] This year, with the development of science and technology, the materials of battery case and cover plate are becoming thinner and lighter. It is also necessary to provide all-round protection for power batteries such as anti-corrosion, explosion-proof, shock-proof, and sealing. [0004] Magnesium and magnesium alloys are one of the lightest metal materials ...
