Abstract

The invention discloses a mains supply complementary solar photovoltaic charging system for an electric car, which comprises a storage battery, a mains power supply, a plurality of solar battery matrixes, a solar controller and a mains complementary inverter, wherein the storage battery and the mains power supply are used for charging the electric motor car to be charged respectively; and the mains complementary inverter performs switching controlling on a power supply loop I between the storage battery and a charging power supply of an electric car to be charged and a power supply loop II between the mains power supply and the charging power supply and converts direct current stored in the storage battery into alternating current so as to charge the charging power supply; charging control switches controlled by the solar controller are connected among the power supply loop I, the power supply loop II and a power supply loop III between the solar battery matrixes and the storage battery in series. The system has reasonable design and simple structure, is economical, practical and convenient to operate and good in operation efficiency, adopts the mode of the combination of solar green energy and the traditional energy, introduces solar energy into the charging system of the electric car and reduces the consumption of commercial power and required resources.

Description

technical field [0001] The invention relates to a charging system for an electric vehicle, in particular to a commercially complementary solar photovoltaic charging system for an electric vehicle. Background technique [0002] Automobile is the main means of transportation in the world today. It brings many conveniences to people's life and accelerates the process of industrialization in the world. However, traditional cars are mainly powered by oil, which pollutes the atmosphere and makes oil, a non-renewable energy source, increasingly scarce. In this context, a new type of automobile with electric energy as the main power has emerged, that is, an electric vehicle. Electric vehicles are mainly powered by electric energy, do not produce exhaust gas, are environmentally friendly and economical. However, electric vehicles use commercial power as the main energy source. In some cities in my country, commercial power is mainly produced by non-renewable energy such as coal. T...
