6 FAQs about [How to choose the inductor of smart car battery pack]

How many inductors are in a battery pack?

This model comprises three inductors (L 1, L 2, and L 3, each rated at 10 mH) and six switches (S 1 -S 6). Four batteries with a nominal voltage of 12.8 V, a cutoff voltage of 10.0 V, a fully charged voltage of 14.4 V, and a maximum capacity of 40 AH (36.2 AH at nominal voltage) form the battery pack.

Is a single inductor based battery topology better?

The results show that the balance of the battery system using the proposed topology is faster than the single inductor-based topology. Moreover, the overall losses occurring across the switches, diodes, inductors, and load are found to be less for the proposed topology. The charge transferred to weak cells from higher cells is also more.
