Abstract

A foldable electronic device includes a first power management module, a first load, and a first battery pack disposed in a first foldable portion of the foldable electronic device. A second power management module, a second load, and a second battery pack are disposed in a second foldable portion in the foldable electronic device. The first power management module controls the first battery pack to supply power to the first load, and the second power management module controls the second battery pack to supply power to the second load. The foldable electronic device further includes an isolation circuit, and the isolation circuit may perform voltage balancing on voltages of two connected batteries.
