The terminal voltage of a battery cell, in accordance with the battery's Thevenin equivalent circuit (battery model explained in section II), is composed of the cell's OCV, and the voltage drop across internal resistance (Karkuzhali et al., 2020).
The rated power of the energy storage battery used in the experiment is 192 W. Set the power response of the battery to 192 W multiplied by the normalized signal, and then divide the power by the nominal voltage of 3.2 V to obtain the current fluctuation signal. Fig. 5 shows the FR operating condition.
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.
As soon as the first cell approaches the minimum voltage threshold, the BMS shuts down the entire battery, even if the remaining cells are still usable (Bouchhima et al., 2016). Consequently, a portion of the energy in the battery pack goes unused, referred to as residual energy.
When the ambient temperature dropped by about 10 °C, the charge–discharge time also decreased by about 10%. At 25 °C, 10 °C, and 0 °C, the battery presented a flat and long voltage plateau. However, when the temperature was −10 °C and −20 °C, the voltage rebounded at the initial stage of charging and discharging.
Based on the test results of a commercial 120 Ah LFP energy storage battery, four typical battery models are established, including the SRCM, the hysteresis voltage reconstruction model (HVRM), the OSHM, and the NNM.
