Modified Multi-inductor-Based Cell Balancing in Electric Vehicles
Single inductor-based cell balancing topology. Figure 4 shows a multi-inductor balancing circuit, where n cells are balanced using n-1 inductors and 2n − 2 switches. The controller senses imbalance, and hence higher cells are switched on first. In this method, the adjacent cells can be balanced directly.
