Meanwhile, the energy storage battery 31 is provided with the temperature control semiconductor chip 42, and heat generated by the energy storage battery 31 is transmitted to the aluminum honeycomb core layer 25 through the first heat conducting plate 43, the temperature control semiconductor chip 42 and the second heat conducting plate 44 in sequence at normal temperature, so that the energy storage battery 31 is simply cooled; when the temperature of the energy storage battery 31 is too low, the semiconductor controller 41 controls the temperature control semiconductor chip 42 to heat rapidly, wherein the heating end of the temperature control semiconductor chip 42 is connected with the first heat conduction plate 43, and then the first heat conduction plate 43 transmits heat to the energy storage battery 31, so that the purpose of preheating the energy storage battery 31 at low temperature is achieved; when the temperature of the energy storage battery 31 is too high, the semiconductor controller 41 controls the temperature control semiconductor chip 42 to refrigerate rapidly, wherein the refrigeration end of the temperature control semiconductor chip 42 is connected with the first heat conduction plate 43, and then the heat of the energy storage battery 31 is transmitted away through the first heat conduction plate 43, so that the purpose of rapidly cooling the energy storage battery 31 is achieved. The arrangement of the temperature control semiconductor chip 42 and the aluminum honeycomb core layer 25 can ensure that the energy storage battery 31 works at a proper temperature, so that the energy storage battery 31 can normally carry out charging and discharging operations.
Further, in this embodiment, as shown in fig. 1, the second surface of the second heat conducting plate 44 is a saw-toothed shape, the second surface of the second heat conducting plate 44 is attached to the aluminum honeycomb core layer 25, and the second heat conducting plate 44 attached to the aluminum honeycomb core layer 25 in a seamless manner can rapidly transmit the heat in the energy storage battery 31 and the temperature control semiconductor chip 42 to the aluminum honeycomb core layer 25 at normal temperature, and then the aluminum honeycomb core layer 25 transmits the heat to the aluminum frame 1 and transmits the heat to the outside of the body through the aluminum frame 1, thereby improving the external heat dissipation efficiency of the energy storage battery 31. The inside of the aluminum honeycomb core layer 25 can be provided with a junction box 5, and the junction box 5 plays a role in connecting an external load, a photovoltaic power generation component, an energy storage component and an internal controller circuit.

Because the suitable temperature range of the energy storage battery 31 during operation is 25 ℃ -50 ℃, when the temperature probe detects that the internal temperature of the energy storage battery 31 is higher than 50 ℃, the temperature probe feeds back data to the temperature controller, the temperature controller can control the temperature control semiconductor chip 42 to refrigerate, wherein the refrigeration end of the temperature control semiconductor chip 42 is connected with the first heat conduction plate 43, so that the first heat conduction plate 43 can quickly take away the heat of the energy storage battery 31 until the temperature probe detects that the internal temperature of the energy storage battery 31 is a certain fixed value (optimally selected between 35 ℃ -40 ℃), the temperature probe feeds back the data to the temperature controller, and the temperature controller can control the temperature control semiconductor chip 42 to stop refrigeration. Similarly, when the temperature probe detects that the internal temperature of the energy storage battery 31 is lower than 25 ℃, the temperature probe feeds back data to the temperature controller, the temperature controller can control the temperature control semiconductor chip 42 to heat, wherein the heating end of the temperature control semiconductor chip 42 is connected with the first heat conduction plate 43, so that the first heat conduction plate 43 can preheat the energy storage battery 31 at a low temperature until the temperature probe detects that the internal temperature of the energy storage battery 31 is a certain fixed value (optimally selected between 35 ℃ and 40 ℃), the temperature probe feeds back data to the temperature controller, and the temperature controller can control the temperature control semiconductor chip 42 to stop heating.
