If these waste batteries are not properly handled, they will cause serious pollution to the environment and waste the valuable metal resources contained in them. Therefore, the recycling and reuse of waste batteries has become an important issue; before recyclable retired batteries, they usually need to be pretreated to ensure safety and improve recycling efficiency. Battery discharge pretreatment is a key step, which aims to safely release the remaining electrical energy inside the battery to prevent short circuits, overheating and even explosions during subsequent physical processing.

[0003] Traditional discharge methods include natural discharge and forced discharge using an external circuit. Although natural discharge is simple, it takes a long time and it is difficult to control the energy release efficiency. Forced discharge using an external circuit can complete the discharge process faster. However, although forced discharge using an external circuit can speed up the discharge speed, it usually requires distinguishing the positive and negative poles of the battery, which is complicated to operate and poses safety risks. Therefore, we have made improvements to this and proposed a battery discharge device. Summary of the invention

Obviously, the described embodiment is only a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the utility model.

[0030] As mentioned in the background technology, traditional discharge methods include natural discharge and forced discharge using an external circuit. Although natural discharge is simple, it takes a long time and it is difficult to control the energy release efficiency. Forced discharge using an external circuit can complete the discharge process faster. However, although forced discharge using an external circuit can speed up the discharge speed, it usually requires distinguishing between the positive and negative poles of the battery, which is complicated to operate and poses safety risks.

[0034] The battery discharge device provided by the utility model has two ends of the battery connected to the graphite block 2 through the battery discharge device to form a closed loop for discharge. During the discharge process, the graphite block 2 is used as a resistance load. When the battery is connected to the graphite block 2, current will flow through the graphite block 2, resulting in consumption of electrical energy inside the battery. In this process, the graphite block 2 plays the role of a resistor, and the role of the resistor does not depend on the positive and negative polarities of the battery. No matter how the positive and negative poles of the battery are connected, as long as a closed loop is formed, the current will flow and the battery will discharge, so that the discharge process does not need to distinguish between the positive and negative poles, and the battery only needs to be connected to the graphite block 2, which greatly simplifies the operation process and avoids safety risks caused by connection errors. Since the graphite block 2 is used as a resistor, the battery is exposed to the external air during the discharge process, which is conducive to heat dissipation and reduces safety risks caused by increased temperature.
