AI Technical Summary
The steel casing and the aluminum alloy flow channel plate cannot be integrated and welded, which affects the production efficiency and integration of the battery pack.
Welding is performed using the same material for the housing body and the flow channel plate, eliminating the need for subsequent flow channel plate installation. Flow channel plates made of aluminum alloy or aluminum are welded to the housing body, and a steel-aluminum-steel composite plate structure is designed to improve strength and thermal conductivity.
The integrated welding of the flow channel plate and the housing has been achieved, which has improved the production efficiency and integration of the battery pack, reduced costs, and improved the economic efficiency and thermal management efficiency of the battery pack.
