The electric storage box 10 is filled with a phase change working medium, such as sodium chloride. The sodium chloride has high latent heat and phase change temperature, and can repeatedly change phase, so that the sodium chloride can be used for more than 20-30 years generally. Therefore, when sodium chloride is used as the chemical energy working medium, the sodium chloride can be used for a long time without replacing the chemical energy working medium, and meanwhile, the sodium chloride has the advantages of nonattenuation, stable performance, unlimited cycle times, no environmental pollution, nonflammability, explosiveness, high quality, low price and the like.

When the high-density latent heat and phase-change temperature raw material is subjected to phase change, the high-density latent heat and phase-change temperature raw material is heated to be changed from a solid state to a liquid state, and electric heat energy is stored; the high-density latent heat and phase transition temperature raw material is cooled to change the raw material from a liquid state to a solid state, and electric heat energy is released.

The electric storage box 10 is provided with an electric heating device (not shown), and when the high-density latent heat and phase transition temperature raw material inside the electric storage box needs to be heated, the electric heating device can be used for heating. The electric heating device is connected with a controller which is used for controlling the point heating device to heat the electric storage box 10. When the electric heating device heats the high-density latent heat and phase change temperature raw materials, the electric energy generated by photovoltaic power generation can be selected for use.

Be provided with first water inlet and first exhaust port on the electricity storage hot box 10, inside first water inlet was used for making the lower water of temperature enter into electricity storage hot box 10, through latent heat and the phase transition temperature raw materials contact with the inside high density of electricity storage hot box 10, cools off the latent heat and the phase transition temperature raw materials of high density, and the lower water vaporization of while temperature forms high temperature steam, discharges through first exhaust port.

In order to make the lower temperature water be vaporized well inside the electric storage box 10, the flow path of the lower temperature water inside the electric storage box 10 may be increased even if the first water inlet and the first air outlet are spaced as far as possible from the electric storage box 10.

For example, taking a rectangular parallelepiped electric storage box 10 as an example, the first water inlet may be provided near one end in the longitudinal direction of the electric storage box 10, and the first air outlet may be provided near the other end in the longitudinal direction of the electric storage box 10, in this way, the length of the flow path of the water having a low temperature in the electric storage box 10 can be increased.

For another example, it is also possible to provide the first water inlet near the lower end portion of the electric storage box 10, and the first air outlet near the upper end portion of the electric storage box 10, and the water at a lower temperature can be more sufficiently vaporized inside the electric storage box 10 due to gravity.
