Abstract

The invention discloses a charging pile control method and device based on an alternating current power line carrier, an alternating current charging pile and a storage medium, and belongs to the technical field of power distribution, and the method comprises the steps: obtaining the charging power information of a to-be-charged device; generating a power distribution result according to the charging power information, and obtaining power distribution scheduling information based on the power distribution result; modulating the power distribution scheduling information through an alternating current power line carrier to obtain a power distribution voltage signal; and the transmission voltage signal is sent to the charging pile, so that the charging pile adjusts the output power according to the transmission voltage signal to charge to-be-charged equipment. According to the invention, the power distribution scheduling information is obtained according to the charging power of the to-be-charged equipment, the power distribution scheduling information is modulated through the alternating current power carrier and then transmitted, and the charging pile obtains the contained power distribution scheduling information through demodulation, so that accurate power information can be obtained and self-discipline control is carried out, and power distribution and output are reasonably carried out; and thus, overall group control of the whole power distribution system is realized.
