Charging pile intelligent power distribution device

Abstract

The invention discloses an intelligent power distribution device for charging piles. The intelligent power distribution device comprises a switch circuit and a control circuit, wherein the switch circuit comprises a power switch circuit and a power supply switch circuit; the control circuit comprises a controller; a signal input end of the controller is connected with a power state detection circuit and a charging pile state detection circuit separately; a signal output end of the controller is connected with power switch drive circuits and power supply switch drive circuits separately; each power switch is connected with the corresponding power switch drive circuit; each power supply switch is connected with the corresponding power supply switch drive circuit; and a power distribution program for controlling on / off of the power switches and the power supply switches according to a power state signal and a charging pile state signal is configured in the controller. According to the intelligent power distribution device, the technical problem that a charging power supply cannot be shared by the charging piles in the prior art is solved, the charging requirements of a plurality of charging piles can be met through the charging power supply with relatively small 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 power distribution device for power distribution to charging piles. Background technique [0002] Because electric vehicles use electric energy as energy, they can not only solve the problem of energy depletion that traditional vehicles have to face, but also achieve zero pollution emissions and meet the needs of environmental protection. Today, the development of electric vehicles has become the consensus of all countries in the world, and it is also a national policy of our country. However, due to the safety of lithium batteries, the short mileage, the high price of lithium batteries and the imperfect charging facilities Restricted by other factors, the promotion process of electric vehicles is slow. [0003] The construction of charging piles is not only a bottleneck restricting the development of electric vehicles, but the development of electric vehicles also rest...
