The invention relates to the field of new energy electric vehicles, in particular to an energy storage and charging method for a new energy electric vehicle and a matched system and device of the energy storage and charging method for the new energy electric vehicle. A new energy electric vehicle energy storage charging method comprises the steps that in the valley electricity price period of the electricity price set by the State Grid of China, namely the 23 o'clock to 7 o'clock every day, a power supply enterprise uses charging equipment, directly uses electric energy generated by a power plant around the power plant and stores the electric energy in a battery, and after the electric energy is stored in the battery in the peak, peak and flat electricity price periods of the electricity price set by the State Grid of China; and using power supply and charging equipment to supply and supplement the electric energy stored in the battery to the new energy electric vehicle. By using the method, on one hand, the problem of insufficient electric energy in the peak flat electricity price period of the State Grid of China can be effectively relieved, and on the other hand, the problem of overhigh charging electricity price of the new energy electric vehicle in the peak flat electricity price period of the State Grid of China can be solved. A good solution can be provided for power supply and charging of the new energy electric vehicle in the peak flat electricity price period of the State Grid of China, the power supply and charging mode of a new energy electric vehicle user is flexible, convenience and practicability are achieved, and application is wide.
