[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] Embodiment 1:

[0026] Figure 1 It shows a schematic structural diagram of a batch battery discharge contact plate 1 in an embodiment of the utility model. Figure 2 FIG. 1 is a top view schematic diagram of the contact surface 12 of the discharge contact plate 1 in the embodiment of the utility model. Figure 3 A schematic diagram of the state in which the electrode terminal of a retired battery is connected to a plurality of contacts 11 in an embodiment of the utility model is shown. The discharge contact plate 1 is used for contact discharge of the retired battery. The discharge contact plate 1 is provided with a contact surface 12. The contact surface 12 is protruding to form a plurality of contacts 11. The contact surface 12 is used for contact discharge with the electrode terminal of the retired battery. Based on the plurality of contacts 11, it is ensured that the contact surface 12 of the discharge contact plate 1 can be connected to the retired battery.

[0027] The plurality of contacts 11 are evenly arranged on the contact surface 12, the center point spacing between any two adjacent contacts 11 is h1, the diameter of the exposed electrode of the electrode end of the retired battery is d1, and the constraint relationship between h1 and d1 is: 0

[0028] Furthermore, when h1=d1, h1 is the midline point spacing between two adjacent contacts 11, that is, the straight line spacing between two adjacent contacts 11 is smaller than the diameter d1 of the exposed electrode of the retired battery electrode end, thereby ensuring that the contact 11 can be connected to the exposed electrode of the retired battery electrode end.

[0029] ​Specifically, in this embodiment, the value range of h1 is: 8mm≤h≤40mm, the center point distance between any two adjacent contacts 11 is determined based on the model size of the retired battery, when the model of the retired battery is a 14500 lithium battery, the diameter of the exposed electrode at the positive terminal of the retired battery is 8mm, and the center point distance between any two adjacent contacts 11 is set to 8mm to ensure that when the retired battery is connected to any position of the contact surface 12 of the discharge contact plate 1, the exposed electrode at the electrode terminal of the retired battery can be connected to part of the contacts 11, thereby improving the reliability of the electrical connection between the discharge contact plate 1 and the retired battery.

[0030] Furthermore, when the model of the retired battery is a 18650 lithium battery, the diameter of the exposed electrode of the positive terminal of the retired battery is 10 mm, and the distance between the center points of any two adjacent contacts 11 is set to 10 mm; when the model of the retired battery is a 21700 lithium battery, the diameter of the exposed electrode of the positive terminal of the retired battery is 13 mm, and the distance between the center points of any two adjacent contacts 11 is set to 13 mm; when the model of the retired battery is a 46800 lithium battery, the diameter of the exposed electrode of the positive terminal of the retired battery is 40 mm, and the distance between the center points of any two adjacent contacts 11 is set to 40 mm. Based on the diameter of the exposed electrode of the positive terminal of the retired battery, it is ensured that the electrode terminal of the retired battery can be connected to the contact 11 of the discharge contact plate 1.

[0031] Furthermore, according to the structural design of lithium batteries, the diameter of the exposed electrode at the positive terminal of current lithium batteries is less than or equal to the size of the exposed electrode at the negative terminal. In this embodiment, the distribution spacing of the contacts 11 is determined according to the size of the exposed electrode at the positive terminal of the retired battery, so that the retired batteries correspond to different positions of the discharge contact plate 1, and it can be ensured that the contacts 11 have good electrical contact with the electrode terminals of the retired batteries.

[0032] Specifically, the diameter of the contact 11 is d2, and the value range of d2 is: 1mm≤d2≤5mm. The contact 11 is set to a small size, so that when the discharge contact plate 1 is connected to the retired battery, the contact area 12 between the contact 11 and the electrode end of the retired battery can be reduced, thereby avoiding the situation where the contact 11 squeezes the retired battery and causes the retired battery to deviate.

[0033] Furthermore, the diameter of the contact 11 is adjusted according to the size of the retired battery, so that the contact 11 can meet the electrical connection requirements of the retired battery of the corresponding size. When the retired battery is a 14500 lithium battery, the diameter d2 of the contact 11 is 1mm, which can ensure that when the contact 11 is connected to the retired battery, the retired battery can maintain a relatively stable state;

[0034] When the retired battery is a 18650 lithium battery, the diameter d2 of the contact 11 is 2 mm; when the retired battery is a 46800 lithium battery, the diameter d2 of the contact 11 is 5 mm, so that the contact 11 can be connected to the electrode end of the retired electrode while avoiding interference with the discharge state of the retired battery, ensuring stable connection between the retired battery and the discharge contact plate 1.

[0035] Specifically, the electrode end of the retired battery is covered with an insulating layer, and the exposed electrode is formed in the middle of the electrode end of the retired battery. The thickness of the insulating layer is h3, and the protrusion height of the contact 11 is h2. The constraint relationship between h2 and h3 is: h2>h3. The protrusion height of the contact 11 is greater than the thickness of the insulating layer, ensuring that the contact 11 can connect with the exposed electrode.

[0036] Furthermore, the insulating skin layer can be a plastic layer, which has good insulation properties and deformation ability. When the contact 11 is against the connection position between the insulating skin layer and the exposed electrode, the insulating skin layer can be deformed based on the extrusion of the contact 11, thereby reducing the thickness of the connection position between the contact 11 and the insulating skin layer, so that the contact 11 is connected to the exposed electrode.

[0037] Furthermore, the material of the discharge contact plate 1 is a metal conductive material, and the metal conductive material is one of metal materials such as copper metal, aluminum metal, iron metal, etc., which has good conductivity to meet the requirements of electrical contact discharge of the retired battery.

[0038] For details, please refer to Figure 3 In this embodiment, the model of the retired battery is set to be a 18650 lithium battery, the diameter of the electrode terminal of the retired battery is D, and D is 18 mm. The diameter d1 of the exposed electrode of the positive terminal of the retired battery is 10 mm. The diameter d2 of the contact 11 is set to 2 mm, and the center point distance h1 of any two adjacent contacts 11 is 10 mm. When the retired battery is connected to any position of the discharge contact plate 1, the exposed electrode of the retired battery is electrically connected to the contact 11 of the discharge contact plate 1, thereby ensuring the discharge stability and reliability of the retired battery.

[0039] The embodiment of the utility model provides a batch battery discharge contact plate 1, by arranging a plurality of contacts 11 on the contact surface 12 of the discharge contact plate 1, and adjusting the distribution spacing of the plurality of contacts 11 according to the model and size of the retired batteries, it is ensured that the exposed electrodes at the electrode ends of the retired batteries can be electrically connected to the contacts 11, thereby improving the convenience of the discharge connection of the retired batteries, being able to simultaneously meet the electrical connection of multiple retired batteries with the discharge contact plate 1, and improving the discharge efficiency and discharge reliability of multiple retired batteries.
