[0023] The present application embodiment first provides a light storage and charging device. Figure 1 , Figure 1 A schematic diagram of the structure of a light storage and charging device provided in an embodiment of the present application.

[0024] like Figure 1 As shown, the light storage and charging device 10 may include a light storage and charging unit 11 , an information acquisition unit 12 , a human body sensing unit 13 and a display unit 14 .

[0025] The information acquisition unit 12 is connected to the light storage unit 11 , the human body sensing unit 13 and the display unit 14 .

[0026] The solar storage unit 11 can be used to obtain solar energy, and can convert the obtained solar energy into electrical energy for storage, and can charge a load (such as a new energy vehicle) with the stored electrical energy.

[0054] In this implementation, the photovoltaic storage unit 11 may further include a charge and discharge control unit 117. The battery module 113 may be connected to the photovoltaic inverter 112 and the battery management unit 114 through the charge and discharge control unit 117.

[0055] The charge and discharge control unit 117 can be used to provide control, measurement and protection when the battery module 113 of the photovoltaic storage device 10 and the photovoltaic inverter 112 transmit electric energy.

[0056] In a possible implementation, the charge and discharge control unit 117 may include a fuse, a shunt, a charge and discharge contactor, and a DC circuit breaker.

[0057] In this implementation, the photovoltaic storage and charging unit 11 may further include an AC circuit breaker 118. The photovoltaic inverter 112 is connected to the mains via the AC circuit breaker 118.

[0058] In this implementation, the photovoltaic storage unit 11 may further include a second switch 119 , wherein the photovoltaic inverter 112 is connected to the load via the second switch 119 .

[0059] In this implementation, the solar storage and charging device 10 may further include a switching power supply 120 .

In addition, the switching power supply 120 is connected to both the information acquisition unit 12 and the human body sensing unit 13 .

[0060] The switching power supply 120 can be used to provide power to the information acquisition unit 12 , the human body sensing unit 13 and the display unit 14 .

[0061] Specifically, the switching power supply 120 can obtain electric energy from the photovoltaic inverter 112, and transmit the obtained electric energy to the information acquisition unit 12 and the human body sensing unit 13, and transmit the electric energy to the display unit 14 through the information acquisition unit 12, thereby providing power for the information acquisition unit 12, the human body sensing unit 13 and the display unit 14.

[0062] The following combination Figure 2 , the specific working principle of the optical storage and charging device provided in the embodiment of the present application is described in detail.

[0064] When the photovoltaic panel assembly transmits electric energy to the photovoltaic inverter 112 , a lightning protection function may be provided by the lightning arrester 116 .

[0065] In addition, the photovoltaic inverter 112 can also receive electric energy transmitted from the mains to the photovoltaic storage and charging device through the AC circuit breaker 118 .

[0066] The photovoltaic inverter 112 can convert the received electric energy and output it to the battery module 113 through the charge and discharge control unit 117.

[0067] After receiving the electric energy, the battery module 113 can store the electric energy.

[0068] When the solar storage and charging device needs to transmit electric energy to the load, the battery module 113 can transmit the electric energy to the photovoltaic inverter 112 through the charge and discharge control unit 117. After the photovoltaic inverter 112 receives the electric energy, it can convert the electric energy and transmit the electric energy to the load through the second switch 119 when the second switch 119 is closed.
