Example Embodiment
[0050] The present invention will be described in detail below with reference to the drawings and embodiments.
[0051] During the use and storage of the battery, the battery discharge voltage, maximum capacity, efficiency, etc. will gradually decline. After the performance is degraded to a certain degree, it will be scrapped because it cannot meet the use requirements. Therefore, the main failure mode of the battery is a performance-degraded failure. For the life prediction of degraded failure products, the method of degradation modeling can be used.
[0052] Degradation modeling must first select the key performance parameters of the product. Internal resistance and available capacity are commonly used characteristic parameters to characterize battery performance status. The internal resistance will gradually increase with the aging of the battery. Many scholars at home and abroad have studied the battery life prediction through the internal resistance, but the research results ...
