AI Customer ServiceWhen working with a capacitor, you will typically see two values printed on the side. The first is the capacitance, obviously, and the second is a voltage. This is the “breakdown voltage,” and it is the maximum voltage that the manufacturer guarantees will not damage the capacitor. You might ask yourself, “How can a voltage damage this capacitor?”
By controlling the closed state of the switch to make the capacitor work in parallel with the battery, the cell with a higher voltage will store the charge in the capacitor and transfer it to the cell with a lower voltage, thereby achieving the battery pack voltage. This circuit has a simple structure and high equalization efficiency.
By using Kirchhoff's voltage law (KVL), the relationship among the cell voltage and the capacitor voltages can be expressed as follows: where iCj, j = 1, 2, , n is the branch current across the capacitor for balancing.
The main difference from the traditional flyover capacitor equalization circuit is that the second layer capacitors C4 and C5 are connected in parallel with the existing first layer capacitors C1–C3. With the second layer capacitor, charge exchange between non-adjacent cells can be performed in one switching cycle.
For optimizing the SC structure in [ 8 ], Shang et al. [ 9] proposed a switched-coupling-capacitor equalizer (SCCE), where four small plates and one big plate are used to form a coupling capacitor with the common nodes. It can directly transfer the energy from the higher voltage cells at any position to the lower voltage cells at any position.
The capacitors are in charge of absorbing the surplus energy from the higher-voltage battery cells, then equalizing the energy among all capacitors, finally injecting the energy into the lower-voltage battery cells.
