“…The initial voltage gap is 94 mV and the equalization threshold is 5 mV. The switch duty ratio is 40% [27]. As shown in Figure 12, the ECANI 4-1 reaches equalization at 0.2718 s and the ECANI 4-2 reaches equalization at 0.1679 s. Because the ECANI 4-2 has two inductors, it can have four equalization modes.…”

Even with the same voltage level, different types of battery packs have different requirements for the volume of the battery equalization circuit. However, most equalization circuits have the same problem: the volume of the equalization circuit is fixed once the voltage level of the battery pack is determined. In order to solve this problem, this paper proposes a novel lithium battery equalization circuit with any number of inductors (ECANI). It can select any number of inductors less than half the number of batteries, even when the voltage level of the battery pack is determined. Simulation and experiments are used to verify the performance of the equalization circuit. The current error and the average final voltage error in the experiment are 1.69% and 0.33% lower than those in the simulation, respectively. So the circuit can achieve equalization with good accuracy.
