A data concentrator and application method for dual-network complementary charging piles in public districts

Abstract

The invention discloses a data concentrator and an application method for a dual-network complementary charging pile in a public community, including a main control board, an LED display screen, an uplink communication module, a downlink communication module, a storage module, a smart meter, a keyboard, an input and output Processing module, LED indicator light and equipment maintenance port, the LED display screen, uplink communication module, downlink communication module, storage module, smart meter, keyboard, input and output processing module, LED indicator light and equipment maintenance port are respectively connected with the main The control board is connected; the data concentrator uses a micro-power wireless module to communicate with the charging piles in the community, which saves the communication fee of each charging pile, reduces the communication expenses in the entire electric vehicle operation network, and reduces the need for direct access to electric vehicles. The communication link in the background of the operation management system improves the running speed of the system background.

Description

technical field [0001] The invention relates to the field of electric vehicle management, in particular to a data concentrator and an application method for dual-network complementary charging piles in public quarters. Background technique [0002] With the support of new energy policies, it is estimated that the demand for new energy vehicles in my country will reach 977,000 in 2015, with an average annual growth rate of 216%. The State Grid Corporation plans to build 1,700 charging stations before 2015, and by 2015, China will have built 2,000 charging stations and 400,000 charging piles. Electric vehicle charging piles are divided into charging piles inside the charging station and discrete piles outside the station, especially the discrete charging piles outside the station, which have a scattered geographical layout and a large number. As electric vehicles enter residents' homes, there will be more and more charging piles in residential areas. At present, the managemen...

Problems solved by technology

Although this invention can solve the problem of limited signal coverage, for public cells, due to the use of various electrical and electronic equipment, there are various harmonics and disturbances in the power line, which leads to increased bit errors in the power carrier signal and affects the communication quality. great influence

[0006] Although the above existing technologies have achieved certain results, there are disadvantages such as short transmission distance, a small number of charging piles that the system can connect to, normal communication outside the signal coverage area, inability to cope with wireless signal interference, and inability to avoid line interference, etc., which cannot meet the needs of electric vehicles. Requirements for charging pile management during large-scale promotion
