description The invention relates to a current control charge device for high voltage direct current transmission secondary equipment, and a charge method thereof. The charge device includes a current limiting subcircuit, an energy storage subcircuit and a CPU controller control loop. The control thinking includes the steps: based on a Maas curve, calculating the acceptable charge current; limiting the initial stage of surge current peak value and avoiding the acceptable charge current by controlling a charge impedance unit and output of a direct current source; monitoring and controlling the voltage and current of the key point of the energy storage loop of a tested product, and cooperatively adjusting the charge impedance unit; and controlling the energy storage subcircuit current so as to control the charge efficiency, wherein a silicon controlled rectifier module in the energy storage loop can realize restriction of the instantaneous reverse back voltage of single energy storage subcircuit; and an overcurrent relay i
