A comparative study of the LiFePO4 battery voltage models under grid energy storage
The energy storage battery undergoes repeated charge and discharge cycles from 5:00 to 10:00 and 15:00 to 18:00 to mitigate the fluctuations in photovoltaic (PV) power. The high power output from 10:00 to 15:00 requires a high voltage tolerance level of the transmission line, thereby increasing the construction cost of the regional grid.
Self-discharge
Self-discharge is a chemical reaction, just as closed-circuit discharge is, and tends to occur more quickly at higher temperatures. Storing batteries at lower temperatures thus reduces the rate of self-discharge and preserves the initial energy stored in the battery. Self-discharge is also thought to be reduced as a passivation layer develops
