However, this process currently suffers from drawbacks such as slow discharge speed, low processing efficiency, and an inability to adjust the number of batteries to be processed, making it difficult to discharge batteries of different specifications. Therefore, there is an urgent need to improve existing used lithium battery discharge devices and provide an adjustable used lithium battery discharge device. Utility Model Content
