Background
With the development of electric automobiles in China, the retired scrapped quantity of power batteries of the electric automobiles is continuously increased. In order to protect the environment, the retired power battery needs to be recycled, and specifically, after a basic unit body (hereinafter referred to as a monomer) forming the battery is disassembled and crushed and a series of chemical procedures are performed, the waste power battery becomes a raw material capable of manufacturing a new battery, so that the aim of recycling is achieved. However, the single bodies of the retired waste power batteries have certain electric quantity, and discharge treatment is performed before disassembly, so that accidents caused by short circuit and fire before disassembly of the single bodies are avoided.
The discharge modes can be currently divided into chemical discharge and physical discharge. The physical discharge method has less harm to the environment because no new substance is generated, and specifically, the method is characterized in that two poles of a monomer are externally connected with a closed loop, so that electric energy is released in the form of heat energy.
For physical discharge, increasing the discharge rate of the monomer is a key point. For example, how to discharge a single body with a given capacity in an alternating manner with discharge currents of different magnitudes to achieve the fastest discharge is a main attack direction of various physical discharge methods. However, this discharge mode uses logic control means, which usually complicates the discharge device itself. During discharging, each single body is connected with a discharging machine through two conducting wires, 2 ten thousand single body connecting wires form a very complex circuit connection system, and meanwhile, a large number of discharging machines with logic control functions are needed, so that high equipment cost and daily operation cost are caused, and the failure rate of the equipment is greatly increased. Therefore, for the huge amount of waste monomers (for example, 2 ten thousand monomers discharged per day), how to meet the environmental protection requirement and the large-batch discharge requirement becomes a technical problem which needs to be solved.

Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. Rather, the invention can be practiced without these specific details, i.e., those skilled in the art can more effectively describe the nature of their work to others skilled in the art using the description and illustrations herein.
Referring to fig. 1, an integrated unit block resistance discharge tray includes a discharge tray 100 and discharge cells 200, a number of the discharge cells 200 being arranged on the discharge tray 100, wherein the discharge cells 200 perform a discharge operation of a battery 400. That is, the entire apparatus is integrated into a tray-type whole by the discharging tray 100, so that the battery 400 as a discharging unit can be loaded, transported, stored, unloaded, and the like by using a forklift. In addition, the discharge tray 100 can be conveniently placed on a multi-layer shelf, so that the space is effectively utilized, and the occupied area is reduced.
Referring to fig. 2, the discharge cell 200 includes an insulating plate 210, an insulating spacer 220, a plate 230, and a resistor 240. The insulation plate 210 is connected to the discharge disc 100 through an insulation block 220. The polar plate 230 is located on the upper side of the insulating plate 210 and corresponds to the positive and negative poles of the battery, the resistor 240 is connected with the insulating plate 210, and the polar plate 230 and the insulating plate 210 are electrically connected by a wire passing through the insulating plate 210. The resistor 240 serves as a discharge load to discharge the battery, for example, to convert the electric energy of the battery cell into heat energy, or to discharge the battery by other means.
Alternatively, the insulation plate 210 and the insulation pad 220 form a gate structure, and the resistor 240 is bolted to the insulation plate 210 inside the gate structure through the ear edge thereof.
Each discharge unit 200 independently forms a discharge loop, and is separated by the insulation flat plate 210 and the insulation cushion block 220 to ensure that no electrical connection exists with other discharge units 200, so that a monomer (discharge monomer) arranged on the discharge unit and other monomers do not influence each other during discharge, discharge is safe and reliable, and the discharge units 200 on the discharge disc 100 are numerous, so that a plurality of monomers can be discharged simultaneously, and the discharge productivity is greatly improved.
In actual operation, the battery 400 is placed upside down on the plate 230 of the discharging unit, and the current passes through the single positive electrode, the plate 230 connected with the single positive electrode, the conducting wire, the resistor 240, the conducting wire and the other plate 230, and then reaches the negative electrode of the battery 400, so that a loop is formed, and the discharging purpose can be achieved.
An LED lamp 250 is arranged between the polar plate 230 and the resistor 240, and the LED lamp 250 is used for indicating the discharge state of the single body, so that the discharge state can be observed conveniently. As an alternative, the led lamp 250 is disposed at one end of the discharge unit 200 below the upper plane of the insulating plate 210, to facilitate rapid observation of the discharge state and to prevent the battery 400 from being bumped.
As an embodiment, the plate 2230 is preferably an aluminum plate rather than an iron plate or other metal plate because aluminum plates are electrically conductive because they do not affect the conductive properties even when the surface is oxidized.
As an embodiment, the resistance of the resistor is selected from a range of 0.1-1 ohm. The maximum discharge current is ampere because the normal single voltage is between 2.5 and 4 volts (for a common power battery, the lithium iron phosphate is about 2.5 volts, and the ternary battery is about 3.2 volts). This discharge current is a small-rate discharge for a general monomer (the capacity of the general monomer is 30 ampere hours or more), and therefore, the discharge current does not cause a hazard due to a large-rate discharge of the monomer.
Regarding the discharge rate, taking a typical ternary cell of 40 ampere-hour as an example, if a resistor 240 with a resistance value of 0.5 ohm is selected, the discharge current is about 8 ampere, and the discharge completion time is small, that is, each discharge unit 200 can complete the discharge of nearly 5 cells per day. Although the discharge speed is not fast, since more than 150 cells are discharged simultaneously on one tray, the number of cells discharged per discharge tray is 750. When 200 discharge trays are used, the number of discharge cells 200 per day is 150000, which weigh about 1 kg, and the weight of discharge cells discharged per day is 150 tons for 200 discharge trays. It is clear that the productivity of this discharge is rather high.
As for the discharge operation, the discharge mode of monomer inversion and contact is adopted, so that the monomer discharge operation is simple and rapid, and the monomer and the tray are always in a static state in the discharge process, and the conditions of poor contact and the like caused by factors such as vibration and the like are avoided, so that the discharge mode is safe and reliable.
Referring to fig. 3, the LED lamp 250 includes a first indicator lamp 251 and a second indicator lamp 252, wherein a positive electrode and a negative electrode of the first indicator lamp 251 are respectively connected to a negative electrode and a positive electrode of the second indicator lamp 252, and the positive electrode and the negative electrode of the first indicator lamp 251 are respectively connected to two ends of the resistor 240, so that the resistor 240, the first indicator lamp 251, and the second indicator lamp 252 form a parallel circuit. As long as the voltage of the single body is not lower than 1.7 v (the forward conducting voltage of the led lamp 250 can reach 1.7 v at the minimum), one led lamp 250 will emit light, indicating that the discharge is normal. When the led lamp 250 is extinguished, it indicates that the cell has discharged below 1.7 volts, and the cell has nearly exhausted its charge (this is determined by the characteristics of the power cell itself). After that, the subsequent regeneration treatment operations such as cutting, crushing and the like are carried out, which is safe and reliable. The bidirectional led lamp type design can reliably display the starting, proceeding and ending processes of resistor discharge, reduce the times of placing monomers and reduce the labor intensity.
A bracket 300 is provided at a lower side of the discharge tray 100 for supporting the discharge tray 100 and even the entire discharge tray device.
The resistor 240 is located under the insulating plate 210, so that the impact of the battery cells on the resistor 240 during the processes of carrying the battery 400 and loading and unloading can be prevented.
Vertical plates 231 are distributed on the polar plate 230 to form a structure with a section similar to a comb, so that the contact stress of the single electrode is increased, the electric conduction is facilitated, and the polar lugs of the battery 400 in different shapes can be matched.
The insulating plate 210 has insulating plate heat dissipation holes 211. The discharge bottom plate 110 is provided with discharge bottom plate heat dissipation holes 111. The design of the heat dissipation holes is beneficial to ventilation and heat dissipation.
Referring to fig. 4, the discharge tray 100 includes a discharge bottom plate 110, a transverse partition plate 120, and a longitudinal end plate 130, the partition plate 120 and the end plate 130 combine to divide the space above the discharge bottom plate 110 into a plurality of areas for accommodating discharge cells 200, i.e., the partition plate 120 and the end plate 130 combine to form a grid-type structure, which can prevent the monomer from collapsing during transportation and effectively discharge the monomer with uneven electrodes, and the discharge cells 200 are connected to the discharge bottom plate 110. In the case of the cells having the rugged positive and negative electrodes, since the cells cannot be vertically placed on the electrode plates 230 of the discharge unit 200, the cells can be still placed on the grid without affecting the discharge process.
A discharge device comprises the integrated unit block resistor discharge tray, the discharge tray and a plurality of improved discharge units are integrated into the integrated discharge tray, the discharge speed of monomers is considered, the quantity of discharge of the monomers can be realized as much as possible, the mass efficient discharge is realized, the environment-friendly requirement is met, and the large-scale production of physical discharge is facilitated.
The present invention can be modified and adapted appropriately from the above-described embodiments, according to the principles described above. Therefore, the present invention is not limited to the specific embodiments disclosed and described above, and some modifications and variations of the present invention should fall within the scope of the claims of the present invention.
