Series power storage battery energy non-dissipative type equalization charging circuit

The invention discloses a power storage battery energy non-dissipative type equalization charging circuit, and in a battery pack comprising multiple sections of power storage batteries, an equalization circuit module is connected beside each single battery, each equalization module comprises an energy storage inductor, a switching device and a diode, and the equalization modules are symmetrically distributed at both sides of the battery pack. When the switching device Sn in each equalization module is turned on, the charging and the energy storage for an inductor Ln is carried out by a corresponding battery Bn, and the current linearity of the inductor is increased; when the Sn is turned off, the energy in the inductor Ln continuously flows into other storage batteries through the diode, the energy storage induction of the upstream battery continuously flows into the downstream battery through the diode, and the energy storage induction of the downstream battery continuously flows into the upstream battery th
