Charging pile control method and device based on direct-current power line carrier and direct-current charging pile

Abstract

The invention discloses a DC power line carrier-based charging pile control method and device, a DC 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 a direct-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 DC 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.

Description

technical field [0001] The invention relates to the technical field of power distribution, and in particular, to a charging pile control method, equipment and a DC charging pile based on a DC power carrier. Background technique [0002] In the related art, in the traditional charging process of charging piles, a power distribution system with the maximum power capacity must be equipped based on the maximum power capacity of a single charging pile, which will cause a great impact on the power distribution system when multiple piles are charged at the same time.
