The invention discloses a charging pile management method based on new-energy automobile positioning. The method includes the following steps that the positions of new-energy automobiles in an area range are obtained; multiple round areas are divided; the number of the round areas with the numbers of the new-energy automobiles exceeding a first cardinal number and lower than a second cardinal number is judged; whether the specific values of the numbers of the new-energy automobiles of the round areas are in a range or not is judged; the numbers and the positions of charging piles in the areaswith the numbers of the new-energy automobiles exceeding the first cardinal number and lower than the second cardinal number are counted; the specific values of the numbers of the new-energy automobiles and the numbers of the charging piles are obtained, whether the specific values are in the range or not is judged, and position coordinates of the charging piles in the areas are sent to mobile terminals of automobile owners; and whether the specific value of the input voltage of each new-energy automobile and the divided output voltage of the corresponding charging pile is 1 or not is judged,and the input voltage is adjusted until the specific value is 1. The charging piles are reasonably used, the use rate of the charging piles is increased, meanwhile, vehicle charging efficiency is greatly improved, and queuing waiting time is shortened.
