Passive equalization is achieved by reducing the voltage of the battery cell, which obviously does not meet the requirements when the voltage of the battery pack is low. Therefore, the battery pack should not be balanced while the voltage of the battery pack is low.
The lithium battery pack balancing control process needs to detect the charging and discharging state of each individual battery. Figure 11 is the lithium battery balancing charging and discharging system test platform, where Figure 11 (a) is the bidirectional active balancing control integrated circuit designed in this paper.
The rated voltage of lithium battery is 3.6 V and the rated capacity is 3 Ah. During the charging and discharging process, direct current (DC) regulated power supply, and electronic load are used for constant current gap balanced charging and discharging. The variation characteristics of SOC and OCV are shown in Figure 3.
Batteries 1–4 in the series lithium battery pack correspond to the four lithium batteries shown in Figure 8. The charged charge SOC, voltage and current collection in the battery information acquisition board correspond to SOC, voltage and current modules shown in Figure 8.
As shown in Figure 9, at ~5400 s, the voltages of B1 and B3 are almost fully charged, while the voltages of B2 and B4 are slightly lower, ~5 mV, and the voltage of the battery pack is ~16.788 V. It should be noted that the voltage of B1 is the lowest at 0 s and, after equalization, its voltage is almost the highest.
The equalization voltage threshold set was 10 mV. After active equalization, the maximum voltage difference between the battery pack cells was reduced to 9 mV, a relative decrease of 96.2%, which met the requirements of the equalization study.
