[0002] Automotive batteries are a very important part of new energy vehicle technology. When installed in pure electric vehicles, the battery serves as the sole power source for the vehicle's drive system. When installed in traditional hybrid vehicles with engines and batteries, the battery can serve as both the main power source and the auxiliary power source for the vehicle's drive system, storing energy during normal driving or deceleration or braking.

[0003] When a new energy vehicle battery fails, it is usually necessary to disassemble the vehicle battery for partial replacement. Since the individual batteries are fixed with adhesive, the adhesive needs to be cut with a knife before the battery is pried out with a screwdriver. This method can easily damage the battery shell. The existing battery disassembly device can only remove one row of individual batteries at a time. Subsequent operations require manual debugging, which increases maintenance time.
