5 FAQs about [New energy battery shell stretching die]
What is energy long cell battery shell?
The new energy long cell battery shell developed and produced by our company adopts a cold bending forming+high-frequency welding process, which breaks through the constraints of traditional deep drawing/extrusion processes and overcomes the welding technology of ultra-thin aluminum shells.
What is the new energy vehicle long cell battery shell sector?
The new energy vehicle long cell battery shell sector, as the company’s main strategic development direction in the future, will become the main sector for the company’s transformation from the traditional automotive industry to the new energy vehicle industry.
What are the disadvantages of a stretched shell?
The stretched shell is affected by the ductility of aluminum, with a minimum thickness of only 0.6mm, heavy weight, and low heat dissipation efficiency. The tensile limit length is below 370mm, and the optional size range is relatively narrow. Low dimensional accuracy and poor surface quality of the stretched shell.
What are the disadvantages of aluminum battery shell?
Low tensile strength and hardness of the aluminum shell of the power battery can lead to low compressive strength and hardness, and the profile is prone to curved and tortuous shapes. Impact on battery stability High-frequency Welded Long Cell Shell Battery Pack
How does a battery pack work?
Good structures: PACK is designed on the upper and lower sides of the battery cell, using structural adhesive to stick two high-strength plates, forming a structure similar to honeycomb aluminum plates, allowing each battery cell to serve as a structural beam.
