The invention provides a battery equalization circuit based on an LCC resonant converter, which is characterized by comprising a battery pack, a switch gating network, an LCC resonant circuit, a half-bridge rectification circuit, a full-wave rectification circuit, a transformer, a control unit, and an acquisition unit. Another technical scheme of the invention is to provide a battery equalizationmethod based on the LCC resonant converter. By monitoring the voltage of each single battery in real time, the batteries needing to be equalized are judged, and energy transfer from the battery pack to the single batteries is realized through the gating switch and the equalization circuit, so that battery equalization is realized. The battery equalization system provided by the invention is simplein topological structure, high in equalization speed and low in control complexity.
