In another example, the user terminal 8 may be further configured to log in to the cloud server 5 through a registered account to view the power information.

Among them, the solar panel 1 (Solar panel) is a device that directly or indirectly converts solar radiation energy into electrical energy through a photoelectric effect or a photochemical effect by absorbing sunlight. The solar cell panel 1 may be a single crystal silicon solar cell panel, a polycrystalline silicon solar cell panel, a copper indium gallium selenium solar cell panel, a cadmium telluride solar cell panel, or a flexible thin film solar cell.

The roof of some electric vehicles is relatively flat, and the solar panel 1 may be disposed on the top of the electric vehicle, for example, directly tiled on the top of the electric vehicle, or on a bracket on the top of the electric vehicle. In order to obtain a better light conversion rate, the solar cell panel 1 can be installed at the top of the electric vehicle at a certain angle, for example, 5 degrees upward, so that it can receive light well and absorb solar energy, thereby improving the light conversion rate. Of course, the solar cell panel 1 may also be disposed in other parts of the electric vehicle, as long as it can absorb solar energy, and details are not described herein again.

Due to the properties and limitations of materials and light, and because the current or voltage output by the solar panel 1 changes with the intensity of the light, the current or voltage generated by the solar panel 1 is often a wavy curve, and That is, the output voltage or current is unstable. If the generated current is directly charged into the electric vehicle battery 6 or directly supplied to the electric vehicle motor 7, the state of charging may be cut off, or it may not be charged at all, which may easily cause electric charging.

In practical applications, the DC / DC controller 9 can also be built into the communication module 4.

Since the user does not have professional skills in the field of solar energy, in order to provide professional consultation to the user, the solar controller 2 and the communication module 4 communicate through the 232 or 485 interface to transfer electrical energy information such as the remaining power of the battery 6 and the input of the solar controller 2. Voltage, output voltage, etc. The communication module 4 can upload the power information to the cloud server 5 through the 4G, 2.5G and other networks by setting the server address and port number. The cloud server 5 obtains the prompt information according to the received power information analysis, and sends the prompt information to the user terminal 8, and the user terminal 8 displays the prompt information. Users can troubleshoot according to the prompt information.

The client 8 includes a PC (personal computer), a tablet, and a mobile phone; the user registers an account with the cloud server 5 through the corresponding software of the PC, tablet, and mobile phone, enters a special password on the communication module 4, and can log in after obtaining the authority This account enables remote monitoring. The prompt information can be displayed in the form of a dialog box on a PC and in the form of an app push on a tablet or mobile phone; the prompt information includes, but is not limited to, solar panel cleaning tips, battery safety tips, etc. These prompts can be cloud The server obtains the information according to the received power information.
