Problems solved by technology

The solar energy + rechargeable battery power supply solution is suitable for the application of Internet of Things equipment in industrial occasions, and has a long service life. Because rechargeable batteries cannot be charged at low temperatures, this solution can only be used in regions with a temperature level above -20°C. Use in extreme cold regions is still limited by rechargeable batteries
Disposable lithium-ion battery power supply, suitable for use in extremely cold areas, but the battery capacity and discharge capacity are limited during the use of the device, and the battery must be replaced frequently

Abstract

The invention relates to a low-temperature power supplying system and method for Internet of Things equipment. The system comprises a solar panel and a disposable lithium ion battery, the positive electrode of the solar panel is connected with an anode of a first diode, the positive electrode of the disposable lithium ion battery is connected with an anode of a second diode, and a cathode of the first diode is connected with a cathode of the second diode. The system has the advantages that the system is simple in structure and can be used in extreme cold weather, and the frequency of replacingthe battery of the Internet of Things equipment can be reduced. The number of times of battery replacement is significantly reduced, and the service life of the system is significantly prolonged by two times; relative to battery replacement, the cost of the added solar panel is not increased; the application of the system is wide, although an intelligent instrument is limited in inner space, anda battery of larger capacity cannot be installed, the outer superficial area of the intelligent instrument can be utilized for adding a solar battery so that the power supplying capacity of the equipment can be improved; the power supplying system is quite suitable for using in the cold north with adequate illumination.
