In recent years, the rapid development of home inverter system is due to its unique characteristics. Its advantages are mainly in the following aspects: 1.Mainly composed of electronic components, does not involve mechanical components, no rotating moving parts, running without noise. 2.There is no combustion process, the power generation process does not require fuel. 3.There is no waste gas pollution in the power generation process, no waste water and waste. 4.Equipment installation and maintenance are very simple, low maintenance cost, reliable and stable operation. 5.Strong adaptability to environmental conditions, can work in different environments. 6.Be able to work under the condition of long time no one on duty. 7.It is easy to carry out the capacity expansion, expanding the scale of power generation.
Although the solar power system has many advantages, so far, there are still many problems that have not been solved. These issues are mainly concentrated in the following aspects: 1.Photoelectric conversion efficiency is very low. Twenty-four percent of the conversion efficiency is the world’s highest and temporarily unable to go beyond. 2.Photovoltaic power generation requires a large area. Although the photovoltaic power generation with the advantages of low-cost raw materials and the production process is simple, but the efficiency of the battery decreased with the area enlarging, this conflict to that the home power inverter systems need plenty of light and wide area. 3.The required illumination is complex, and the selection of the solar radiation should be appropriate. If the sun is not enough or cloudy or rainy or high temperater, the efficiency of the solar photovoltaic effect will be greatly reduced. 4.Photovoltaic power generation cost is too high, can not meet the requirements of large-scale popularization and application.

Electric vehicle as a development prospect of the broad green transport, the future will be very rapid pace of popularization, the future of the market is also very huge market prospects. In the context of the global energy crisis and environmental crisis is serious, the Chinese government actively promote the application and development of new energy vehicles, charge for power plants as required for the development of electric vehicles an important supporting infrastructure, with a very important social and economic benefits. A campaign to build an 220v EV charger / replacement station is already in the country.
The whole system is composed of four parts: portable electric vehicle charger, concentrator, a battery management system (BMS), charging management service platform.
220v electric car charger, the control circuit is realized by the embedded ARM processor, the user can self card user authentication, balance inquiries, billing inquiries, can also provide voice output interface, the realization of interactive voice. The user can according to the liquid crystal display to choose 4 kinds of charging mode: including charging, charging according to charge, automatically charging, charging according to the mileage, etc..
Electric vehicle charger controller and concentrators using CAN bus for data exchange, concentrator and the server platform using wired internet or GPRS wireless network data exchange, for the sake of safety, electricity charges and the amount of data realized security encryption.
The main function of the battery management system (BMS) is monitoring the battery working state (battery voltage, current and temperature), prediction power battery battery capacity (SOC) and the corresponding residual driving mileage, battery management to avoid over discharge, over charge, overheating and monomer battery voltage is seriously unbalanced phenomenon, to maximize use battery storage capacity and cycle life.
Charging service management platform has three main functions: charging management, charging operation, integrated query. Charging management related to the system of basic data for centralized management, such as information of electric vehicles, battery information, user card information, electric vehicle charging units information; charging operations mainly to the user for charging management, integrated query to query on data management and operation of the comprehensive analysis.
Now in China, the charging station infrastructure construction is in peak, the attention of the government and enterprises in the charging station professional services is recharge or changing the power of choice, the China charging station integrated services have yet to be developed.
1, charging station successful operation case: China existing two largest most mature electric vehicle charging station is Beijing Olympic Games charging stations in the Shanghai World Expo and charging stations, the two charging stations at present is for electric city bus to provide fast battery replacement service, two charging stations are currently does not belong to the formal business operations, but governmental organizations under the pilot run. After two charging stations in common is dominated by a group of local bus operation, charging station founded and funded by a major national special fund and the place, running electric bus ownership bus group, Beijing Olympic charging station power battery lease from the battery manufacturers, according to the amount of electricity used per month paid battery manufacturers leasing costs (about 1 degree electricity 4 yuan), and the Shanghai World Expo charging stations directly from the battery manufacturers to buy batteries, also battery manufacturers responsible for early battery maintenance, and complete the relevant technical personnel training, the ownership of the battery belongs to the charging station.
2, at present, the national grid is accelerating cooperation with local governments to speed up the progress of the construction of charging stations.
