[0002] Battery aging is an indispensable link in the lithium battery production process. The aging of lithium batteries generally refers to the placement of batteries after the first charging and formation after the battery assembly and filling are completed. It can be aging at room temperature or at high temperature. The purpose is to stabilize the properties and composition of the repair film formed after the initial charging.

[0003] The lithium batteries in the prior art still have the following defects when they are aged:

[0004] 1. Batteries must be placed one by one manually into the corresponding battery charging position of the aging rack / cart / cabinet, which is a huge workload and inefficient;

[0005] 2. The aging environment is relatively open, so it is not possible to verify the battery's extreme charging at a constant temperature.

[0006] 3. The power cabinet uses a main power supply to charge multiple batteries. The distribution accuracy of the charging current of each battery is not high, or each battery is equipped with a charger, which makes the charging power supply inefficient.

[0007] 4. For new guide pin lead type batteries, existing aging equipment or methods are not suitable for the needs of new battery interface technology;

[0008] 5. In the existing technology, when the battery is defective, there is no anti-explosion and anti-fire function, which poses certain safety hazards. Summary of the Invention

[0023] In this application, before using the equipment, the aging furnace temperature is raised to the set temperature after the device is turned on. The battery is automatically arranged through electromagnetic and vibration technology, and then sent to the loading platform through direct vibration. The loading platform detects the presence of material and starts the contour gripper to move the battery to the pin separation station to separate the battery pins. The contour gripper then moves the battery to the shaping station to arrange the battery pins into a uniform shape and send it downward. The battery arrives at the polarity detection station, and the polarity detection electronic circuit identifies the battery polarity and sends it to the reversing station. Those that need to be reversed are reversed, and those that do not need to be reversed pass directly. The battery is then sent to the test machine conveyor belt for pre-aging pre-testing. By applying a certain voltage to the positive and negative poles of the battery and detecting the current passing through the battery, it is determined whether the battery has an open circuit or a short circuit, and defective batteries are removed. The test machine conveyor belt carries the battery to the polarity marking detection station. The color sensor uses color recognition to confirm whether the polarity marking on the battery outer packaging is reversed and removes defective batteries. The test machine conveyor belt delivers 45 batteries to the aging fixture position of the aging machine each time it is fully loaded. The PLC counts the number and activates the aging machine carrier fixture to pick up the 45 batteries. The batteries are then driven downward in the direction indicated in the above equipment layout diagram and delivered to the first charging station of the aging machine. When the second 45 batteries enter the first aging machine charging station, the aging machine uses a motor, chain and other transmission structures to transport the first 45 batteries to the second aging machine charging station for charging. This process continues step by step until the 226th charging station, at which point the first 45 batteries on the aging machine fixture are unloaded to the testing station. After the batteries are unloaded to the testing station, they are driven by the test machine belt to the testing station. The battery internal resistance and voltage are tested by instruments to screen out good and defective products. Good products are transported out to the good product loading fixture, and defective products are removed and transported out to the defective product loading fixture, completing the entire aging and testing process.

[0024] Beneficial effects:

[0025] The present invention designs a structure for high-current conductive contact of lithium battery aging. This structure can ensure that the conductive copper block and the conductive copper spring are in full contact with each other, and achieves no sparks during operation through technical means. By changing the power supply structure, the conductive structure can withstand high current shocks of 30A to 50A, ensuring stable power supply, ensuring that the power consumption of multiple batteries is met at the same time, and eliminating safety hazards caused by overload or contact sparks.

[0026] In the present invention, a single-cell constant-voltage and constant-current charging circuit for batch aging of lithium batteries is designed to achieve independent power supply for each battery, and a separate chip controls the charging process. If a battery has an abnormality, other products will not be damaged. This circuit has multiple protection functions such as input overvoltage, undervoltage, output overcurrent, overshoot, and overheating protection. Once an abnormality occurs during charging, the output will be shut down in time, thereby avoiding battery overheating and explosion, and fundamentally solving safety hazards. This circuit also has multiple modules that can be cascaded through the communication port, and the number is not limited. This design also supports the on-board embedded single-chip computer communication function, which can be remotely controlled and exchange data with the computer in real time, and has a more flexible usage method;

[0027] The present invention designs a dual-protection power supply structure for a fixture for batch aging of lithium batteries. When each lithium battery is aged, the positive copper foil wire and the positive clamping spring of the fixture on the aging machine simultaneously power the positive electrode of the battery, and the negative copper foil wire and the negative clamping spring of the fixture on the aging machine simultaneously power the negative electrode of the battery. The above design solves the problems of manual loading one by one, one battery requiring one charger, or multiple batteries sharing one power supply and being unable to charge and protect individual batteries, solves the needs that existing battery aging equipment cannot adapt to under the new battery interface, and solves the problem of keeping the charging environment temperature constant.

[0028] In the present invention, the equipment system includes a power supply cabinet, which provides a current of 5V5000A to the carrier in the aging furnace, and provides power charging to the battery through the aging high-current conductive contact structure, the single-cell aging constant voltage and constant current charging circuit and the dual protection power supply;

[0029] In the present invention, the equipment system includes a feeding vibration table and a feeding module, which realizes automatic arrangement, shaping, polarity detection, reversal, open and short circuit pre-detection, and shell mark polarity detection of batteries through electromagnetic and vibration, ensuring that the batteries entering the aging furnace have the correct posture, polarity and direction;

[0030] In the present invention, the equipment system includes an aging machine cabinet, an aging machine internal carrier fixture, a heating and air supply system in the furnace, and a constant temperature function of the furnace can be achieved by temperature setting. Through the special design of the carrier fixture, namely the aging high current conductive contact structure, the single-cell aging constant voltage and constant current charging circuit and the dual protection power supply structure, the battery products can be effectively charged and aged under the environment required by the design.

[0031] In the present invention, the equipment system includes a testing machine system and a feeding system. After the aged products are tested, the batteries are transported to the testing position through the feeding structure. Good and defective products are identified through calibrated instruments and the products are discharged separately.

[0032] The present invention provides an online system for automatic batch aging and testing of flow-type guide needle and lead lithium batteries. The system has a reasonable structural design and high stability. The functions of loading, aging charging, testing, unloading and classification are concentrated in the same system. In addition, the system realizes automatic polarity detection, battery pin shaping, feed pre-detection and shell packaging polarity detection during the loading process, so as to detect, correct and eliminate defects early, and fully improve the effective utilization rate of the aging process.

[0054] refer to Figure 11 The schematic diagram of the single-cell aging constant voltage, constant current charging, and data acquisition circuit of the present invention utilizes a battery charging management chip U2 to implement constant voltage and constant current charging, as well as various protection functions such as battery undervoltage, battery overcurrent, battery short circuit, and input overvoltage. A voltage and current acquisition chip U6 is added to enable real-time acquisition of battery voltage, current, and battery capacity, enabling battery capacity testing and outputting battery capacity results in milliampere-hours or watt-hours, thereby achieving battery aging and capacity grading. During operation, the entire circuit is controlled by a microcontroller unit U3. Chip U6 is actually an analog-to-digital converter (ADC), which acquires the battery voltage and current in real time and converts the acquired voltage and current data into milliampere-hours or watt-hours using a special formula. Finally, the circuit communicates with a computer through the circuit's communication interface, ensuring that the relevant battery capacity data can be read during the testing phase, thereby achieving the capacity grading function. The battery charging capacity is calculated as follows: Capacity C = Battery Charging Current I × Charging Time (Hours) T. For example, if a battery is charged with a current of 500MA (milliamperes) for 2 hours, then the charging capacity of the battery is equal to 500mA*2h=1000mAh=1Ah. Of course, the voltage and current change in real time during charging, so the charging capacity of the battery is accurately measured by collecting voltage and current at fixed intervals (such as 1mS).
