Description

Technical Field

[0001] This utility model relates to the field of battery resource recycling technology, and in particular to a battery discharge system. Background Technology

[0002] Used batteries retain residual charge. Disassembling and crushing them while they are energized can easily lead to fires, explosions, and other safety accidents. Therefore, it is necessary to release the residual charge from used batteries before disassembly. Currently, there are physical discharge (load-heated discharge) and chemical discharge (salt water immersion discharge). Existing physical discharge equipment mainly dissipates the charge through an external load, i.e., by connecting the battery to a resistor. The charge in the battery is dissipated through heat release. However, this method is only suitable for laboratory experiments and is not feasible for large-scale discharge.

[0003] Existing physical discharge devices do not discharge completely and have low safety performance. Summary of the Invention

Detailed Implementation Example

[0033] This battery discharge system is a highly efficient and safe battery testing device, mainly composed of a discharge unit and a cooling unit, connected by an inlet and outlet water pipe to form a closed-loop system. The discharge unit is responsible for discharging the battery, while the cooling unit ensures that the heat generated during the discharge process is effectively dissipated to maintain the operating temperature of the battery and the discharge unit within a safe range.

[0034] The core supporting component of the discharge unit is the frame, which not only provides the supporting structure for the entire discharge assembly but also houses the water tank and discharge components. The water tank provides a constant temperature environment to ensure proper battery discharge. The discharge assembly includes the discharge mechanism, clamping base, adjusting slider, guide pillars, switch knob, voltmeter, and mounting plate.

[0035] The discharge mechanism is a key component of the discharge assembly. It consists of multiple sets of elastic adjustment seats, spring guide posts, an upper electrode insulating plate, an upper electrode plate, a battery clamping plate, a lower electrode insulating plate, a lower electrode plate, and a heating plate. These components work together to ensure not only the stability and safety of the battery during the discharge process, but also the accuracy and reliability of the discharge process.

[0036] The cooling unit mainly consists of a chiller and a circulating water tank. Its function is to remove the heat generated by the discharge unit through circulating water, thus maintaining a stable temperature for the discharge unit. A filter screen is installed in the circulating water tank to ensure the cleanliness of the circulating water and extend the service life of the equipment.

[0037] The entire discharge process is controlled by a switch knob, and the residual voltage of the battery can be monitored in real time using a voltmeter. The design of the discharge mechanism allows the clamping base to move up and down on the guide post by adjusting the slider, making it easy to accommodate batteries of different lengths. In addition, the multiple sets of discharge components allow the equipment to discharge and test multiple batteries simultaneously, improving work efficiency.

[0038] To further enhance safety, the electrode plates are connected to the frame via an insulating plate to prevent electrical leakage. The heating plate is placed in a water tank, transferring heat to the water. Once the water temperature rises, it is cooled by a cooling system to maintain a stable temperature. Example

[0039] In use, within the battery discharge system, the battery clamp is responsible for securing the battery, ensuring its stability during discharge. The battery clamp is installed between the upper and lower electrode plates and fixed to the clamping base via a fixing device. After installation, the operator can turn on the switch knob to initiate the discharge process.

[0040] The discharge mechanism clamps a battery with a battery clamp, fixing it in the discharge position. The two electrode posts of the battery are connected to the upper and lower electrode plates respectively, forming a complete discharge circuit. The upper electrode plate is connected to the heating plate through the upper electrode wire, and the lower electrode plate is connected to the heating plate through the lower electrode wire, thus forming a closed discharge circuit between the battery and the heating plate.

[0041] During discharge, the heat generated by the battery is conducted to the water through the heating plate, raising the water temperature. The hot water is then cooled by a cooling system to maintain a stable temperature. This design ensures both safety during the discharge process and improves discharge efficiency.

[0042] The entire discharge process is controlled by the operator via a switch knob, and parameters such as voltage and current during discharge can be monitored in real time using monitoring devices such as voltmeters. The battery clamp design ensures the stability and safety of the battery during discharge, while also facilitating operator operation.
