An intelligent power distribution system for charging piles

Abstract

The invention discloses an intelligent charging pile power distribution system. The intelligent power distribution system comprises a plurality of charging power sources and a plurality of charging piles and further comprises an intelligent power distribution device and an upper computer. The intelligent power distribution device is in both-way communication connection with the upper computer, andthe upper computer can issue data to the charging power sources and the charging piles. The intelligent power distribution device comprises a switching circuit and a control circuit. The current input end of each charging pile is connected into the current output end of the corresponding charging power source through the switching circuit. A power distribution program for generating on-off control signals according to a power state signal and a charging pile state signal is configured in a controller. A switching driving circuit is connected between the switching circuit and the signal outputend of the controller, and the switching driving circuit can control the switching circuit to be switched on and off according to the on-off control signals. According to the intelligent power distribution system, technical problem that in the prior art, charging piles cannot share a charging power source is solved, the charging needs of the charging piles can be met through the charging power sources small in capacity, and the construction cost of the charging piles is reduced.

Description

Technical field [0001] The invention belongs to the technical field of charging piles, in particular to a charging pile intelligent power distribution system used for power distribution to charging piles. Background technique [0002] Because electric vehicles use electric energy as energy sources, they can not only solve the problem of increasingly depleted energy that traditional cars have to face, but also achieve zero pollution emissions and meet the needs of environmental protection. Nowadays, the development of electric vehicles has become the consensus of all countries in the world and is also a national policy of our country. However, due to the safety of lithium batteries, the short driving range, the high price of lithium batteries and the imperfect charging facilities of electric vehicles Restricted by other factors, the promotion of electric vehicles is slow. [0003] The construction of charging piles is the bottleneck restricting the development of electric vehicles,...
