Alternating current charging pile system on basis of TD-LTE (time division long term evolution) network

Abstract

The invention provides an alternating current charging pile system on the basis of a TD-LTE (time division long term evolution) network. Application of the TE-LTE network is combined. A charging pile substation serves as a site management center of alternating current charging piles, an analysis result on fault diagnosis of the site charging piles is provided via an embedded WEB server, aerial update service is provided for site charging pile firmware, load for an alternating current charging pile group is controlled and scheduled, remote fault diagnosing and monitoring and program updating service are realized, maintaining efficiency is improved, orderly charging is guaranteed by load controlling and scheduling, normal power supplying is reduced, charging quality for users is guaranteed, and stability of a power grid is maintained.

Description

technical field [0001] The invention relates to the field of new energy electric vehicle charging, in particular to an AC charging pile system based on a TD-LTE network. Background technique [0002] With the deepening of the global energy crisis, the depletion of oil resources and the increasing harm of air pollution and global temperature rise, governments and automobile companies generally recognize that energy saving and emission reduction are the direction of future automobile technology development, and the development of electric vehicles will be The best way to solve these two problems. my country attaches great importance to the development of electric vehicles, and the country has issued a series of standards to support and regulate the development of electric vehicles. In the draft "Energy Conservation and New Energy Vehicle Industry Planning", it is pointed out that pure electric vehicles will be the main strategic orientation. Relevant experts pointed out that...
