- Recently, batteries used in electric vehicles have been at risk of thermal runaway, which is a major safety concern. This is because the constant charging and discharging of the battery causes the cells to deteriorate, resulting in a voltage difference between the cells, which leads to overcharging. In an electric car, there are more than 7,000 battery cells that make up the battery pack. Most fires are reported to be caused by poor management of the battery cells. The battery cells must all operate at the same voltage during charge and discharge operations. For this behavior, we need to monitor the unit battery cells on a per-cell basis and perform a balancing action if we encounter a battery cell with a different voltage to bring it to the same voltage. In traditional balancing behavior paper [1], the direct connection between the battery cell and the electrical and electronic balancing behavior circuits causes the high voltage of the battery to cause problems for the low voltage circuits. Another paper [2] proposed to implement self-balancing based on the resistance and current behavior characteristics of battery cells so that the battery voltage behaves evenly, but aged battery cells have incorrect behavior if the battery cell does not follow the resistance and current behavior characteristics of the cell. The paper in [3] proposed an active balancing behavior structure using a photo detector, but it still has a structure where the high battery voltage can affect the low voltage circuit. In this paper, a balancing circuit is proposed as an isolated structure balancing circuit to secure stable balancing behavior in order to overcome the problems of balancing circuit caused by voltage difference and heating caused by high voltage even in the battery combination environment operating up to thousands of volts in the electric vehicle environment. To realize this, we proposed and designed a separate controller interface circuit block and a balancing circuit block.
