Cui Dongshu: electric vehicles to develop models suitable for use in county and rural areas] Cui Dongshu, secretary general of the Federation, said in a post on his personal Wechat official account that the current electric vehicles are basically charging vehicles, the reverse power transmission function is not yet available, and the charging mode of photovoltaic charging piles is not yet mature, so effective product design is needed to meet the needs. By encouraging the owners of new energy vehicles to charge and store energy during the low hours, and reverse discharge to the power grid during the peak hours, a dynamic and effective energy system of "new energy vehicles + power grid" is constructed, which plays the role of cutting peak and filling valley. At present, BYD's products are very good, with external power supply, can output electricity, other models should also keep up. Cui Dongshu said that at present, after each electric vehicle is charged and used every day, at least 20kWh electricity can participate in the grid energy storage and peak shaving service. If the number of rural electric vehicles in China reaches 50 million by 2030, it is assumed that each electric vehicle will charge the grid with 5kWh every day, and the annual charge will reach 70 billion kWh. This is a huge improvement in electricity and a good reflection of farmers' income.
