[0021] The concept, concrete structure and technical effects of the present disclosure will be described clearly and completely with the help of embodiments and drawings, so as to fully illustrate the objective, characteristics and effects of the present disclosure. Obviously, the described embodiment is only a part of the embodiment of the invention. Based on the embodiment of the invention, other embodiments obtained by those skilled in the art without paying creative labor belong to the protection scope of the invention. Furthermore, all the connection / connection relationships involved in the disclosure do not mean that the components with a single finger are directly connected, but that a better connection structure can be formed by adding or reducing the connection accessories according to the specific implementation situation.All technical features of creating disclosure can be combined interactively without conflicting with each other.

[0022] Before shipment, lithium batteries typically require several rounds of charge and discharge tests to activate the chemistries in the battery, a process known as forming. Due to individual differences, even batteries in the same batch have different capacities. For operational use, it is often necessary to combine batteries of the same capacity in series and parallel, requiring the detection and matching of batteries of identical capacities, a process known as grading. Therefore, during the battery forming and grading step, the battery forming and grading system must charge and discharge the batteries repeatedly and calculate the capacity of each battery during this process.Therefore, the basic components of the system for battery forming and grading consist of a charging part and a discharging part.

[0023] In existing systems for forming and grading batteries, the charging and discharging circuits are generally arranged in a single module. Each workstation can be charged and discharged, and the charging and discharging of a lithium battery share a workstation. As a result of this arrangement, the charging circuit or the discharging circuit is inactive, forming an inactive circuit within a forming device, which leads to additional energy consumption and a low utilization rate of electrical energy.

[0024] In order to solve the above problems, the present application provides an efficient and energy-saving system for forming and classifying batteries.

[0025] Referring to [Fig.l] and [Fig.2], an efficient and energy-saving system for forming and grading batteries according to the present application comprises a busbar 1, a charging station and a discharging station. The charging station is provided with a charging module 2 for charging the lithium battery on the charging station, and the discharging station is provided with a discharging module 3 for discharging the lithium battery on the discharging station. Both the charging module 2 and the discharging module 3 are electrically connected to the busbar 1, which itself is connected to an external constant current source for supplying power to the charging module 2 and the discharging module 3.

[0026] More specifically, the bus bar 1 is connected to the external constant current source, and is electrically connected to the charging module 2 and the discharging module 3, so as to supply power to the charging module 2 and the discharging module 3. The charging module 2 is arranged on the charging station to charge the lithium battery 4 on the charging station. The discharging module 3 is arranged on the discharging station to discharge the lithium battery on the discharging station. The charging module 2 and the discharging module 3 are arranged independently, so that the charging module 2 and the discharging module 3 can work simultaneously, which avoids the additional power consumption caused by an idle circuit, and improves the utilization rate of electric energy and the efficiency of forming and grading the battery.

[0027] In this embodiment, the charging station and the discharging station are arranged alternately, so that after charging or discharging the lithium battery, it only needs to be moved to the next work station to complete a complete charging and discharging cycle, thereby improving the efficiency of a forming and grading cycle.

[0028] According to one or more embodiments, the efficient and energy-saving system for forming and classifying batteries comprises a charging transfer unit 5, which is arranged below the charging module 2 and the discharging module 3. The charging transfer unit 5 moves a lithium battery from the station from the load to the discharge station after charging is complete, or from the discharge station to the load station after discharging is complete, thereby facilitating the completion of the charge-discharge cycle. In some examples, the load transfer unit 5 is a conveyor belt. Without limitation, it can be understood that the load transfer unit 5 may also be a manipulator or an automatic guidance device.

[0029] According to one or more embodiments, the efficient and energy-saving system for forming and grading batteries comprises a forming device 7 for charging the lithium batteries. In order to improve the efficiency of the forming and grading process, the forming device 7 is configured to hold and secure a plurality of lithium batteries to be formed and graded. And the forming device 7 charged with a plurality of lithium batteries is placed in a charging station or a discharging station, so that the charging module 2 or the discharging module 3 at a single station can charge or discharge a plurality of lithium batteries, which greatly improves the efficiency of the forming and grading process. In some examples, three lithium batteries are loaded in a forming device 7.Without limitation, it can be understood that the number of lithium batteries loaded in the forming device 7 can be adjusted according to the actual situation.

[0030] According to one or more embodiments, the efficient and energy-saving system for forming and classifying the battery comprises a limiting unit 6, which is disposed on one side of the charging transfer unit 5 and is used for intercepting, positioning or releasing the lithium battery. When the charging transfer unit 5 moves the lithium battery to a designated station, the limiting unit 6 intercepts and positions the lithium battery, so that the lithium battery can be stabilized at the designated station. When the lithium battery completes the charging or discharging task at this station, the limiting unit 6 releases it and the charging transfer unit 5 moves the lithium battery to the next station.

[0031] In one embodiment, the limiting unit 6 is disposed on one side of the charging transfer unit 5, and the limiting unit 6 is a barrier clamp. When the lithium battery is moved to the station designated by the charging transfer unit 5, the limiting unit 6 extends horizontally above the charging transfer unit 5 under the drive of the motor or the cylinder, so as to intercept, position and firmly fix the lithium battery, and stabilize the lithium battery at the designated station. After the lithium battery has completed its charging or discharging task at this station, the limiting unit 6 releases the battery and retracts to leave the charging transfer unit 5 from above. under the power of the engine or cylinder, so that the battery can be moved to the next station by the load transfer unit 5. Without limitation, it can be understood that the limiting unit 6 may also be arranged under the load transfer unit 5, and the limiting unit 6 may also be a baffle or other structure. In another embodiment, the limiting unit 6 is arranged under the load transfer unit 5, and the limiting unit 6 is provided in the form of a baffle structure.When the lithium battery is moved to the designated station by the charging transfer unit 5, the limiting unit 6 is driven by the motor or the cylinder to rise vertically, and its highest point is higher than the horizontal plane of the charging transfer unit 5, so as to intercept and position the lithium battery and stabilize the lithium battery at the designated station. When the lithium battery is charged or discharged at this station, the limiting unit 6 descends vertically under the action of the driving of the motor or the cylinder, and its highest point is lower than the horizontal plane of the charging transfer unit 5, so that the limiting unit 6 does not block the movement of the lithium battery, and the charging transfer unit 5 moves the lithium battery to the next station.

[0032] According to one or more embodiments, the efficient and energy-saving system for forming and classifying the battery comprises a charging connection means 8 and a discharging connection means, wherein the charging connection means 8 is arranged above the charging station and is electrically connected to the charging module 2, and wherein the charging connection means 8 is used to connect the lithium battery on the charging station with the charging module 2 to form a charging circuit. The discharging connection means is arranged above the discharging station and is electrically connected to the discharging module 3. The discharging connection means is used to connect the lithium battery on the discharging station with the discharging module 3 to form a discharging circuit.In addition, the efficient and energy-saving system for forming and grading the battery further comprises a drive unit, and the drive unit is used for driving the charging connection means and the discharging connection means into contact with the lithium battery to form an electric circuit.

[0033] More specifically, the charging connection means 8 is arranged below the charging module 2 and above the charging station. The charging connection means 8 is electrically connected to the charging module 2, and can be electrically connected to the lithium battery on the charging station, so that the lithium battery and the charging module 2 form a charging circuit. The discharging connection means is arranged below the discharging module 3 and above of the discharge station. The discharge connection means is electrically connected to the discharge module 3, and can be electrically connected to the lithium battery on the discharge station, so that the lithium battery and the discharge module 3 form a discharge circuit.

[0034] The charging connection means 8 is provided with at least one first positive probe and at least one first negative probe. When the charging module 2 charges the lithium battery on the charging station, the first positive probe is electrically connected to a positive electrode of the lithium battery on the charging station, and the first negative probe is electrically connected to a negative electrode of the lithium battery on the charging station. In one embodiment, the charging connection means 8 is provided with three first positive probes and three first negative probes, so that three lithium batteries can be simultaneously connected to the charging module 2. Without limitation, it can be understood that the number of the first positive probe and the first negative probe can be adjusted according to the number of lithium batteries charged on the forming device 7 and the actual situation.

[0035] Similarly, the discharge connection means is provided with at least one second positive probe and at least one second negative probe. When the discharge module 3 charges the lithium battery on the discharge station, the second positive probe is electrically connected to the positive electrode of the lithium battery on the discharge station, and the second negative probe is electrically connected to the negative electrode of the lithium battery on the discharge station. In one embodiment, the discharge connection means is provided with three second positive probes and three second negative probes, so that three lithium batteries can be simultaneously connected to the discharge module 3. Without limitation, it can be understood that the number of the second positive probe and the second negative probe can be adjusted according to the number of lithium batteries charged on the forming device 7 and the actual situation.

[0036] The drive unit is used to drive the charging connection means and the discharging connection means to contact the lithium battery to form an electric circuit. Specifically, when the lithium battery is moved to the charging station by the charging transfer unit 5, the drive unit drives the charging connection means downward until the first positive probe of the charging connection means contacts the positive electrode of the lithium battery, and the first negative probe of the charging connection means contacts the negative electrode of the lithium battery. And then the drive unit stops the descent of the charging connection means and stabilizes the position of the charging connection means. Once the lithium battery has completed a charging task, the drive unit drives the charging connection means upward, so that the first positive probe of the charging connection means leaves the positive electrode of the lithium battery and the first negative probe of the charging connection means leaves the negative electrode of the lithium battery.

[0037] More specifically, the operating process of the efficient and energy-saving system for forming and classifying batteries according to the present application is as follows.

[0038] A plurality of forming devices 7 loaded with one or more batteries to be formed and classified are placed on the loading transfer unit 5; the loading transfer unit 5 carries the forming device 7 loaded with the lithium batteries to be formed and classified and moves it to a designated station, and the limiting unit 6 intercepts and positions the forming device 7 loaded with the lithium batteries to be formed and classified.The drive unit then drives the charging connection means connected to the charging module 2 and the discharging connection means connected to the discharging module 3 downward, so that the positive probe on the connection means is connected to the positive electrode of the lithium battery, and the negative probe on the connection means is connected to the negative electrode of the lithium battery, thereby forming a circuit between the charging module 2 or the discharging module 3 and the lithium battery for charging or discharging tasks. When the lithium battery is charged or discharged, the drive unit drives the charging connection means connected to the charging module 2 and the discharging connection means connected to the discharging module 3 upward, so that the positive and negative probes of the connection means leave the positive and negative electrodes of the lithium battery.The limiting unit 6 retracts and thus releases the forming device 7, and the charge transfer unit 5 then carries the forming device 7 loaded with the lithium batteries and moves it to the next station. Due to the independent arrangement of the charging module 2 and the discharging module 3, all the charging modules 2 and the discharging module 3 can operate simultaneously, which greatly improves the efficiency of the lithium battery forming and grading process.
