[0002] With the increasing attention to climate change problem in the world, reducing the use of traditional fossil energy, increasing the development and utilization of new energy has become a consensus. This provides a broad market space for the new energy industry. The improvement of energy storage technology makes the storage and deployment of new energy more efficient. New energy storage technologies, such as lithium ion battery energy storage, flow battery energy storage, compressed air energy storage, etc., have continuously improved performance and gradually reduced costs, providing strong support for the large-scale application of new energy, which makes the energy storage industry have a explosive growth.
[0003] Square lithium iron phosphate battery is one of the core components of energy storage system, so the test amount of square battery is huge, and the discharged battery has a major hidden danger, which needs to be discharged. At present, there are two main ways to discharge the battery: one is to discharge through the charge and discharge equipment with negative power module, and to connect to the positive and negative poles of the square battery; the other is to weld the square battery with a piece of sheet, which needs to increase the welding equipment. The above two methods need to increase additional equipment, and the relative cost is high.

When the resistance is small, the battery temperature rises quickly, which has a certain safety hazard. And the existing discharge device needs to be equipped with different devices according to the specifications and models of square battery to adapt, which cannot match the batch battery with one device.

Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.
[0020] EMBODIMENT
[0021] The square battery discharging device comprises a battery clamp body, a sliding rheostat, and a connecting device. The battery clamp body comprises an insulating base 4, a fixed seat 7, and a cell lower baffle 5. The sliding rheostat and the fixed seat 7 are fixed on the insulating base 4. The sliding rheostat is provided with a left connecting post 2 and a right connecting post 8. The fixed seat 7 is provided with a sliding rail and two conductive copper posts 10. The two conductive copper posts 10 move left and right on the sliding rail. The left connecting post 2, the right connecting post 8, and the two conductive copper posts 10 are connected by the connecting device, which is a wire. The cell lower baffle 5 is fixed in a sliding groove of the insulating base 4 and can move towards or away from the fixed seat 7 along the sliding groove of the insulating base 4.
[0022] The two conductive copper posts 10 are respectively provided with left and right contact pole adjusting devices 3 and 9, which are sheep horn bolts.
[0023] A movable sliding sheet 1 is arranged on the sliding rheostat, and the sliding rheostat is a 1Ω sliding rheostat. The cell lower baffle 5 is provided with an adjusting and fastening device 6, which is a long handle bolt, so as to fix the cell on the insulating base 4.
[0024] The working principle of the square battery discharging device is as follows: a square cell is placed on the insulating base 4. The position of the conductive copper post 10 is adjusted by adjusting the sheep horn bolt, so as to align the positive and negative pole positions of the square cell, and the sheep horn bolt is tightened. The voltage value of the cell is tested. When the voltage value of the cell is greater than 1V, the left connecting post 2 of the sliding rheostat is connected with the left adjusting device 3 of the cell contact pole by a wire, and the right connecting post 8 is connected with the right adjusting device 9 of the cell contact pole. The cell lower baffle 5 can be moved to a length suitable for the battery by adjusting the long handle bolt, so that the conductive copper post 10 and the cell pole are tightly connected, and the long handle bolt is tightened. If the voltage value of the cell is less than 1V, the resistance value of the sliding rheostat is adjusted so that the current is less than 4A.
[0025] Specifically, as an embodiment, the square cell is placed on the discharging device. After the square cell is discharged to 1.5V, the positive and negative poles of the cell are connected to the 1Ω sliding rheostat. At this time, the discharging current of the cell is about 3A, and the whole device can be controlled below 45℃. After discharging for 4 hours, when the voltage is discharged to below 0.7V, the resistance of the sliding rheostat is adjusted to 0.1Ω, so that the whole device can also be controlled below 45℃. After discharging for 3 hours again, it can be discharged to below 0.3V, which ensures the safety of the whole discharging process. The whole discharging process is ensured within the safe temperature, and the complete discharging process is realized at a low price.
[0026] The above-described embodiments only express the specific implementation manners of the present application, and the description is relatively specific and detailed, but it should not be understood as a limitation on the patent scope of the present application. It should be noted that for ordinary skilled persons in the art, without departing from the concept of the present application, a number of modifications and improvements can be made, which are all within the protection scope of the present application.
