Problems solved by technology
However, the current power supply method uses a solar power supply device to supply power to one electrical device. If the power consumption of different electrical devices is different, then the same solar power supply device cannot be compatible with different electrical devices, and there is a problem of poor compatibility.
At the same time, using a solar power supply device to supply power to a piece of electrical equipment still has the disadvantages of low power supply reliability and insufficient battery life.

The embodiment of the invention provides a power supply device and system, and relates to the technical field of power supply. The power supply device comprises a control module and a battery, at least one input port of the control module is electrically connected with at least one first power supply device, at least one output port of the control module is electrically connected with at least oneload or is electrically connected with at least one load through a plurality of second power supply devices, and the control module is electrically connected with the battery. The control module determines the one with the highest electric quantity in the at least one first power supply device and the battery to supply power to the load according to the first electric quantity information provided by each first power supply device and the second electric quantity information of the battery; or the electric quantity information with the highest electric quantity is transmitted to the at leastone second power supply device electrically connected with the power supply device, so that the at least one power supply device with high electric quantity information is selected from the at least one first power supply device, the power supply device of the battery and the plurality of second power supply devices to supply power to the load. The power supply device has the advantages of high power supply reliability and high cruising ability.
Description
technical field [0001] The present invention relates to the technical field of power supply, in particular to a power supply device and system. Background technique [0002] Current outdoor electrical equipment (for example, weather stations, monitoring stations, etc.) is generally powered by solar energy because it is far away from the mains. However, the current power supply method uses a solar power supply device to supply power to one electric device. If different electric devices have different power consumption, then the same solar power supply device cannot be compatible with different electric devices, and there is a problem of poor compatibility. At the same time, the method of using a solar power supply device to supply power to an electrical device also has the disadvantages of low power supply reliability and insufficient battery life. Contents of the invention [0003] The object of the present invention includes providing a power supply device and system, wh...
