What is battery balancing?
Battery balancing maximizes the useful capacity of the pack by guaranteeing that all cells in the pack have the same SOC. This implies that you can maximize the use of your battery pack whether you're driving an electric car or using a renewable energy storage system to power your home.
What is active battery balancing?
Active battery balancing uses the energy shuttle of capacitance or inductance to transfer the energy in the high SOC battery to the low SOC battery and redistributes the energy by designing a specific energy converter.
How does a battery balancing agent work?
This agent takes the current state information from the battery pack (cell voltages, SoC, temperatures, and SoH, etc.) and then selects a set of balancing actions to execute that will minimize the voltage or SoC imbalances between battery cells.
Does balancing a battery increase the rechargeable capacity?
During the balancing process, the balancing current is very small and the charging speed is fast; equalization does almost nothing to increase the maximum rechargeable capacity of the battery pack. We divided different balance intervals according to different voltage of the battery cell, as shown in Figure 6. Equilibrium interval division.
