Also, overcharging can cause unstable conditions. To increase battery cycle life, battery manufacturers recommend operating in the reliable SOC range and charging frequently as battery capacity decreases, rather than charging from a fully discharged SOC or maintaining a high SOC.
Depth of Discharge (DOD) A battery’s lifetime is highly dependent on the DOD. The DOD indicates the percentage of the battery that has been discharged relative to the battery’s overall capacity. Deep discharge reduces the battery’s cycle life, as shown in Fig. 1. Also, overcharging can cause unstable conditions.
However, excessive discharge depth and frequent changes in operating conditions can accelerate battery aging. Deep discharge depth increases BESS energy consumption, which can ensure immediate revenue, but accelerates battery aging and increases battery aging costs.
In additions, deep discharging can cause internal stress on the battery, which can lead to other issues such as reduced charging capacity and decreased overall performance. The capacity degradation of a battery is accelerated by repeated deep discharges and recharges at high SOC .
Rechargeable batteries lose stored energy when they’re not being used because an idle battery undergoes internal chemical reactions that slowly drain its energy. This “self-discharge” process can eventually consume active ingredients in the cathode, where the electron-spent lithium ions collect while the device is in use.
Results reveal the deterioration of the internal structure of traction batteries due to the overdischarge behavior and play a guiding role in the testing and evaluation of the safety of traction batteries.
