What are the important factors that cause battery degradation?

The four important factors that lead to battery degradation are: 1. Battery operating temperature 2. Battery current 3. Battery average state of charge (SOC) 4. Battery average state of charge (SOC) swing, that is, the average battery where the battery is most of the time State of Charge (SOC) interval. The third factor and the fourth factor are related. There are two strategies for managing battery life in a project. The first strategy is that if the project is supported by revenue, the battery size can be reduced and future replacement costs can be reduced in the plan. In many markets, project revenue can support future replacement costs. Under normal circumstances, the future cost reduction of components should be considered in the estimation of future replacement costs, which is consistent with the relevant market experience in the past 10 years. The second strategy is to increase the size of the battery so that the overall current (or C-rate, which simply means charging or discharging per hour) is minimized by paralleling the batteries. Since the battery will generate heat during charging and discharging, lower charging and discharging currents often result in lower temperatures. If there is excess available energy in the battery energy storage system and less energy is used, it will reduce the charge and discharge of the battery and extend its service life. Battery charge and discharge capacity is a key term. The automotive industry generally uses cycle as a measure of battery life. In stationary energy storage applications, the battery is more partially cycled, that is, it may be partially charged or partially discharged, and each charge and discharge is insufficient. Available battery energy. The application of energy storage system may be less than one cycle per day, and depending on the market application, it may also exceed this indicator. Therefore, the staff should determine the battery life by evaluating the throughput of the battery. Disclaimer: Some pictures and content of articles published on this site are from the Internet.
