The invention discloses a rapid nondestructive charging method of a power-driven light automobile and a charger, and belongs to the technical field of power-driven automobile charging. The rapid nondestructive charging method is characterized by comprising the following steps: step 1001, starting; step 1002, initializing hardware; step 1003, detecting whether a battery pack and the charger are matched; step 1004, alarming failure; step 1005, detecting whether a quick charging mode is carried out; step 1006, charging not quickly; step 1007, charging quickly; and step 1008, charging completely. The charger comprises a soft start protective module, an input rectification filtration module, an auxiliary power supply module, an insulation driving module, a charge control module, a power output module, an output rectification filtration module, an output opposite connection protection module and an output parameter sampling module. According to the invention, based on a slow impulse nondestructive quick charging technique, quick charging is realized, meanwhile the battery pack is nondestructive, and the service life of the storage battery pack is prolonged.
