The charging power supply consists of an input filtering unit, a rectifying unit, a phase-shifting full-bridge conversion unit, a high-frequency transformation unit, a full-wave rectifying and filtering unit and a control unit. In the charging process, the balanced charging module detects the voltage value of each battery cell in real time, when the voltage value of a certain battery cell reaches a threshold value, the parallel consumption resistor of the battery cell is started, the voltage value of the battery cell is ensured not to exceed the specified voltage, and other battery cells continue to charge until all the battery cell voltages reach the specified value. The wire connection spring type electrode clamping device at the charging power supply end is fixed on the clamping mechanism of the unmanned aerial vehicle nest, and after the unmanned aerial vehicle falls down, the clamping mechanism completes the clamping and restoring action, the spring type electrode clamping device can clamp the unmanned landing gear, and the unmanned aerial vehicle starts to charge.
