The invention discloses a quick charging method for energy-storage capacitors of electronic detonators. The method comprises the following steps: controlling the output
voltage of a
bus in a control host in two stages by the control hosts: in the first stage, increasing the
bus output
voltage from 0V to a safe
voltage V1 gradually, and under the safe voltage V1, controlling the electronic detonators to charge energy-storage capacitors therein to increase the voltage from 0V to the V1 so as to detect whether the electronic detonators are normal or not; in the second stage, increasing the
bus output voltage from V1 to an
initiation voltage V2 gradually, under the voltage V2, adopting a closed-loop charging control method for charging all the electronic detonators in a network at the same time so as to achieve charging to the electronic detonators, and when the control host and the electronic detonators are networked, the control host quickly accomplishes an
initiation operation procedure after confirming the functions of all the electronic detonators in thenetwork; and during an
initiation process, all the electronic detonators in a network enter into a relatively dangerous ready initiating preparation state, the time for the ready initiating preparation state is relatively short, and the occurrences of safety accidents are effectively reduced.
