Recently, as electric vehicles operate using battery voltages, issues such as thermal run-away or fire in batteries have been reported. The primary cause of this thermal runaway is the volt-age difference between cells that occurs during charging and discharging processes. Therefore, it is essential to accurately balance the battery using a battery management system (BMS). This paper proposes an isolated balancing circuit designed to stably maintain the balance of each unit cell in a high-voltage battery pack structure. The control circuit signal is transmitted to a photo diode, and the balancing operation is controlled using signals from an optical detector. The low-voltage oper-ation control circuit is isolated from the high-voltage circuit, enabling reliable balancing even under high voltages of thousands of volts. The cell-by-cell register operation method allows simultaneous balancing of multiple cells. A balancing current of 80 mA was achieved, and within a temperature range from -20°C to 80°C, the balancing operation showed a variation within 81 mA ± 1 mA, owing to the temperature-compensated balancing mechanism of the isolation circuit. The proposed bal-ancing circuit is designed to operate at an ultra-low power of 180 μW, minimizing the battery energy consumption required for the balancing operation.
