The invention discloses an electric vehicle equipment power supply and distribution method, and relates to the field of power supply and distribution. The electric vehicle equipment power supply and distribution method aims to achieve the purposes that electric vehicle charging devices are wide in range, high in density and low in distribution spot cost. Traditionally, a bus of street lamps is provided with a power supply unit additionally for charging an electric vehicle, the bus supplies power all day, and the street lamps can be controlled to be turned off. The bus of the street lamps is divided into a plurality of sections in an isolating mode, and supplement power sources supply power in a subsection mode, so that the power supply capacity is multiplied. Isolating switches among the sections achieve combination of the sections and power supply changeover. On-site or remote communication is utilized for achieving recognizing, controlling, measuring and paying. When the street lamps are all used, semiconductor energy-saving lamps are used, a part of the lamps are turned off or used with the power reduced at midnight and the lamps are out of use in the daytime, electricity can be used by equipment such as electric vehicles day and night on the bus in a high power mode. The method can be applied to lines such as the street lamps which can be used discontinuously or of which the electricity load can be reduced, charging piles can be constructed widely and compatibly, so that the small electric vehicles can be charged at the early stage, electric cars can be guided to develop at the later stage, and a general and practical intelligent instrumented micro grid can be formed.
