Electric energy supply system for electric vehicle

Abstract

The invention provides electric energy supply system for an electric vehicle, and particularly relates to a highly intelligent electric energy supply system for the electric vehicle. The electric energy supply system comprises a power supply and distribution system, a charging system, a monitoring system and a metering and billing system; the charging system comprises a direct current charger and an alternating current charging pile; the metering and billing system comprises a gateway meter, a direct current ammeter, an alternating current ammeter, a metering manager and a billing system; and the monitoring system comprises power supply and distribution system monitor, charging system monitor and a monitoring center. The electric energy supply system for the electric vehicle improves the intelligence and the automation level of the electric energy supply system for the electric vehicle while meeting the basic function of the electric energy supply system for the electric vehicle, and achieves the purposes of unattended operation or few-people on duty and economical, safe and efficient running of the electric energy supply system for the electric vehicle. The configuration scheme and the equipment selection method for the electric energy supply system for the electric vehicle provide the specific design reference for the construction of a charging station for the electric vehicle.

Description

technical field [0001] The invention relates to electric vehicle power supply technology, in particular to an electric vehicle electric energy supply system. Background technique [0002] As a clean and environmentally friendly green vehicle, electric vehicles have attracted great attention from governments and automobile manufacturers around the world. Among them, Japan, affected by its own resources, started earlier in research on the development of electric vehicles. In the 1990s, Toyota, Honda and other auto companies in Japan launched electric vehicles and hybrid vehicles, and established experimental electric vehicle charging stations in some places. Nissan, Japan's third largest automaker, plans to launch a Tiida-based practical pure electric vehicle in 2010, and has established charging stations for electric vehicles in major cities in Japan. The United States and European countries have also carried out extensive research on electric vehicle charging facilities. I...
