The invention discloses a method, equipment, a system and a distribution for quickly changing a power battery. The system comprises a hardware part and a software part, wherein the hardware part comprises a general parking platform, two multifunctional manipulators, two battery storage platforms, two stacking equipment, video acquiring equipment and other auxiliary equipment; and the software part comprises a vehicle type parameter database, a vehicle type identification system, an image data processing system, a programmable logic controller (PLC) control system and other auxiliary systems. An operation process is that after a vehicle of which batteries are to be changed is parked on the general parking platform, the video acquiring equipment acquires the real-time vehicle image data, the image data processing system acquires the accurate position of a battery compartment, the PLC control system controls the multifunctional manipulator 1 to take away the power leakage batteries when the multifunctional manipulator 1 operates below the battery compartment, meanwhile, the battery charging manipulator 2 takes and conveys the fully charged batteries from the battery storage platforms to a part below the battery compartment of the vehicle, and the batteries are lifted to be installed in the battery compartment. The vehicle is driven down from the parking platform, so that the battery charging is completed.
