Intelligent street lamp management system with electric vehicle wireless charging management function

Abstract

The invention belongs to the field of power supply for electric vehicles, and particularly relates to an intelligent street lamp management system with an electric vehicle wireless charging management function. The system comprises a monitoring center, a street lamp centralized controller communicating with the monitoring center through a GPRS network, multiple single lamp controllers communicating with the street lamp centralized controller through power lines, and multiple electric vehicle wireless charging piles communicating with the monitoring center through the GPRS network, wherein the street lamp centralized controller is arranged in a transformer; a power line led out from the transformer is laid on the road surface; one end of each single lamp controller is arranged in a lamp rod, and the other end is connected with the power line; each electric vehicle wireless charging pile is located below the power line corresponding to each single lamp controller; the electric vehicle wireless charging pile is a wireless charging transmission module; and the power line and each wireless charging transmission module are not physically connected. The electric vehicle wireless charging management function is added on the basis of realizing intelligent management on the street lamps, linkage with the intelligent street lamp management system is realized, and unified control and management are realized.

Problems solved by technology

[0002] With the increasing environmental pollution problems such as oil shortage and smog, the government has introduced a series of policies to support the development of electric vehicles, but the construction of basic charging facilities is relatively lagging behind, resulting in slow promotion of electric vehicles

[0003] If the charging station is built in the form of a traditional gas station, it will bring many problems: First, the charging equipment of the gas station cannot meet the charging demand. If the time required to fully charge the vehicle is not directly refueling, it will take more time There are a lot of them. It takes about 2 hours to charge through gas station-style charging equipment, and it takes about 10 hours to charge at a slow rate. Such charging is inefficient and causes queuing for charging, which is not conducive to promotion.

Second, there are potential safety hazards in traditional gas station-style charging stations. If the problem of long charging time and queuing at the charging station is solved, it is adopted to equip each vehicle with a location for charging at the charging station, on the premise of ensuring profitability. Let every electric vehicle be able to charge, considering that most car owners will not stand by the vehicle when charging, this may lead to unexpected situations such as deliberately destroying the charging gun, stealing electricity and leakage

Third, large-scale construction of charging stations will occupy valuable land resources, and many cities no longer have large tracts of land to build charging stations, and most of the idle land is urban green belts. Land resources, which itself violates the starting point of the country's development of new energy vehicles, but will bring about the impact of damaging the environment, and the construction of the charging station itself must meet the "three links and one leveling" (water, electricity, roads, site leveling) The site selection itself is very difficult, so the land factor is fatal to the construction of the station, and it is not feasible to build a large-scale centralized construction of traditional gas station charging stations

However, although charging stations in the form of traditional gas stations have many advantages, they still cannot completely solve the problem of charging piles occupying excess land.

[0005] In recent years, there have been related reports on the use of street lamps and cables to build electric vehicle charging piles, but the charging piles are all independent of the street lamp system. Most of the street lamp systems are used to lay two cables, and the street lamp uses a single cable. The electric vehicle charging pile uses another cable separately. This wiring method is actually not related to the street lights. In this wiring method, the electric vehicle charging piles are all wired. In addition to troublesome use, there are also electrical contacts that cannot be connected. Solve the problems of waterproof and moisture-proof and contact aging, and the exposed electrical contacts and cables are easy to be damaged, and it is not easy to realize unattended

[0006] There are many ways of street lamp control system, but there is no street lamp system with electric vehicle wireless charging management function in the prior art

The direct problem caused by the inconsistency between the street lamp control system and the charging system is that the load cannot be controlled and managed in a unified manner. We can only blindly increase the capacity of the transformer so that all street lamps and charging piles can run at full load at the same time, otherwise there will be overload and failure. unsolvable problem
