  • Power transfer circuit for achieving power transfer between stacked rechargeable battery cells
    Patent number: 9595836
    Abstract: A power transfer circuit for achieving power transfer between stacked rechargeable battery cells is disclosed. The power transfer circuit includes an inductor, a first switch, a second switch and a controller. A loop of the rechargeable battery cell having higher power and the inductor is conducted so that the inductor stores power until the current flowing through the inductor meets the cutoff amount. Then, a loop of the rechargeable battery cell having lower power and the inductor is conducted so that the inductor releases the power saved in the inductor to the rechargeable battery cell having lower power until current flowing through the inductor changes direction. Therefore, balance between the rechargeable battery cells can be achieved.
