Abstract

The invention provides a system and a method for using natural energy to supply power to electric automobile. The method converts solar energy into electric energy for storage through a solar photovoltaic power generation array or through a wind-powdered generator array to supply power filling station with power for charging storage batteries of electric automobiles. Meanwhile, the system is connected with a commercial power grid, so that redundant power generated by the solar photovoltaic power generation array in sunny days or the wind-powered generator array in heavy wind days can be injected into the commercial power grid for use by other loads; and at night or in cloudy and rainy day, or in small wind days, alternating current of the commercial gird is converted into direct current to be stored for the power filling stations to charge the storage batteries of the electric automobiles. The commercial power and power generated by the solar photovoltaic power generation array or the wind-powered generator array are used complementarily. Therefore, the system and the method can use natural energy stably and reliably to supply power to the electric automobiles, reduce the dependence of the electric automobiles on petroleum, coal and other non-renewable energy resource, relieve energy crisis and protect the atmospheric environment.

Description

technical field [0001] The invention relates to the technical field of natural energy power generation applications, in particular to a system and method for using natural energy to supply energy to electric vehicles. Background technique [0002] We all know that the global energy shortage is getting worse. According to the global energy report, the current global oil reserves can be used for 40 years; natural gas reserves can be used for 67 years; coal can be used for 167 years. Therefore, the development and utilization of new energy sources is the general trend. Among them, natural energy has become one of the key research directions because of its clean, pollution-free and renewable advantages. [0003] Taking solar energy as an example, it is estimated that the total annual solar radiation in my country is 917-2333kWH / m 2 , as of 2006, the total mileage of my country's highways is 1.8563 million kilometers. If 1 / 10 of the roads are used to install solar photovoltaic...
