AI Customer ServiceIf you have plenty of excess power available you could employ a simpler balancing circuit by just placing a resistor in parallel with each capacitor. To properly balance them with this method, the resistor must be sized to allow at least 10x the current through them as there is leakage current through the capacitors.
The effect is that all of the capacitors can reach their optimal voltage value with no overcharging of any one capacitor and with the least amount of balancing current. If you have plenty of excess power available you could employ a simpler balancing circuit by just placing a resistor in parallel with each capacitor.
A chip like Texas Instruments’ BQ33100 can balance 2, 3, 4 or 5 capacitors. It will supervise up to a 9-capacitor string. It’s useful for applications like blade computers, medical equipment, uninterruptible power supplies, and RAID storage systems. 6.
Recent advances in energy storage systems have speeded up the development of new technologies such as electric vehicles and renewable energy systems. In this respect, supercapacitors have gained interest due to their unique features such as high power density, long lifespan, and wide operating range.
The passive or energy dissipative balancing circuit is simple in design, control, execution, small, and cheap. However, they produce a lot of heat and less efficiency. Inactive or non-energy dissipative balancing, any C2C circuits short in size and flexible but required a sophisticated control system and take balancing time.
