摘要（英）：

A charging circuit used for a super capacitor group with a voltage balancing capability. Each super capacitor monomer of the super capacitor group is connected in parallel with an energy release control module and a voltage detection and signal transmission module; all the energy release control modules are connected in parallel with a first diode (D1); a first inductor (L1) and a second diode (D1) after being connected in series are connected in parallel with an energy transfer capacitor (Ct); the voltage detection and signal transmission module provides a signal for indicating whether each super capacitor monomer is overcharged for a controller (401); the voltage detection circuit (301) is connected to the super capacitor group, transmits a signal to the controller (401) and provides a voltage state of the super capacitor group for the controller (401); the controller (401) controls the energy release control module and a charging control module (501) to balance voltage of each monomer in the super capacitor group and realize a DC/DC (Direct Current) reduced voltage charging function.
