The paint process is rust-proof, and after enclosure, the cabinet 1 has a accommodating cavity for placing discharge devices and electronic components such as controllers (not shown). The panel 101 includes an upper panel 1011 and a lower panel 1012. The upper panel 1011 is tilted toward the accommodating cavity of the cabinet 1 to facilitate operator operation and visual effects. The upper panel 1011 is equipped with a display screen 2, a discharge switch 3 and a power switch 4. The display screen 2 is connected to the controller and can be used to set discharge data. For power battery packs of different models and specifications, the discharge curve is displayed, including discharge time, discharge voltage, discharge current and other information, and the discharge status of the used power battery pack can be displayed in real time; the discharge switch 3 is used to control the on and off of the discharge status; the power switch 4 is used to control the on and off of the external power supply. The backplate 102 is provided with a total current interface 9 on the top, which is connected to the controller and is used to collect discharge current parameters. A rectangular concave panel 1021 is provided in the middle of the backplate 102. This concave panel 1021 is formed by stamping and bending toward the accommodating cavity. It is provided with a discharge positive terminal interface 10, a discharge negative terminal interface 11, a total voltage positive terminal interface 12, and a total voltage negative terminal interface 13. The discharge positive terminal interface 10 and the discharge negative terminal interface 11 are connected to the positive and negative discharge clamps via two cables. The discharge clamps are respectively connected to the positive and negative tabs of the used power battery pack to be discharged, allowing the used power battery pack to quickly complete the discharge process. The total voltage positive terminal interface 12 and the total voltage negative terminal interface 13 are connected to the discharge positive terminal interface 10 and the discharge negative terminal interface 11 to collect real-time voltage during the discharge process. The discharge terminal positive terminal interface 10, discharge terminal negative terminal interface 11, total voltage positive terminal interface 12, and total voltage negative terminal interface 13 are mounted on the concave panel 1021, not protruding from the surface of the back panel 102. This protects the terminals from damage during movement. A power supply interface 14 is located below the back panel 102 for connecting to an external power source to power the discharge cabinet.

[0022] At the upper part of the cabinet 1, there is a drawer 107 for storing discharge cables, discharge clamps and general tools. The discharge cables and discharge clamps are arranged in pairs.
