TECHNICAL FIELD
[0001] The present application relates to the technical field of retired battery screening, and particularly relates to a retired battery gradient screening device. BACKGROUND
[0002] With the rapid development of electric vehicles and large-scale energy storage systems, a large number of power lithium batteries are facing the problem of retirement. If these retired batteries are directly scrapped, it will cause resource waste and environmental pollution. Therefore, how to efficiently utilize the retired batteries in a gradient manner has become a research hotspot.
[0003] The existing retired battery screening methods mainly include manual visual inspection and electrical parameter testing. The manual visual inspection depends on the experience judgment of the operator, and is low in efficiency and easy to be affected by subjective factors. The electrical parameter testing evaluates the battery health condition by measuring the voltage, current, internal resistance and other parameters of the battery. Although this method is high in accuracy, it is time-consuming and not suitable for large-scale application. In addition, there is an internal structure damage identification method based on X-ray imaging technology. This method can non-destructively observe the damage inside the battery. However, due to the high cost of the equipment, it is difficult to popularize in actual production.
[0004] The existing manual visual inspection method is low in efficiency and strong in subjectivity. The electrical parameter testing method is high in accuracy but large in time consumption. The X-ray imaging technology can effectively identify the internal damage of the battery, but the investment cost is too high, which is not conducive to popularization and application. These three methods cannot meet the demand of rapid classification of large-scale retired batteries. CONTENT OF THE NEW TYPE
