Embodiment 1

[0038] This embodiment provides a power supply method. The power supply method adopts a complementary manner of solar energy and mains power. The solar energy is converted into electrical energy to charge a storage battery, and then the storage battery supplies power to a base station. As a supplement to the mains power supply, the solar power supply mode effectively solves the power supply problem of base stations in power-scarce areas. The applicable scenario of this power supply method can be in areas where power resources are scarce, using solar energy and electric energy to supply power to the base station to prevent the base station from not working properly due to insufficient power resources; the system can also be applied to other scenarios, as long as the light Sufficient places can be used. As a clean energy source, solar energy not only reduces power consumption, but also reduces environmental pollution.

Embodiment 2

[0051] see image 3 , the present embodiment provides a power supply controller 1, including a first switch tube 11, a second switch tube 12, a third switch tube 13, and a fourth switch tube 14. The power supply controller is used for:

[0052] Judging the storage power of the battery 2;

[0053]If the storage power of the storage battery 2 reaches the highest safe value, the third switching tube 13 is turned on, and the storage battery 2 supplies power to the base station 5;

[0054] If the storage power of the storage battery 2 does not reach the highest safety value, it is judged whether the solar cell assembly 3 has electric energy output, and if so, the first switching tube 11 and the third switching tube 13 are turned on, and the storage battery 2 still supplies power for the base station 5, At the same time, the battery 2 is charged by the solar cell assembly 3; if not, the fourth switching tube 14 is turned on, and the base station 5 is powered by the mains 4 .

Embodiment 3

[0059] see Figure 4 , this embodiment provides a power supply system, including a base station 5, a mains 4, a battery 2, a battery management system 6, a solar battery module 3, and a power supply controller 1, wherein,

[0060] The storage battery 2 is used to store electric energy, receives charging from the mains 4 or the solar battery module 3 through the power supply controller 1, and supplies power to the base station 5 through the power supply controller 1;

[0061] The battery management system 6 is used to detect the stored power of the battery 2, and transmit the stored power of the battery 2 to the power supply controller 1;

[0062] The solar cell assembly 3 is used to convert solar energy into electric energy, charge the storage battery 2 through the power supply controller 1 , and transmit the output electric energy signal to the power supply controller 1 .

[0063] The power supply controller in this embodiment adopts the power supply controller in Embodiment...

Abstract

The invention discloses a power supply method, a power supply controller and a power supply system, which belong to the field of the electric power supply system. The power supply method comprises the following steps that: the storage electric quantity of a storage battery is judged; if the storage electric quantity reaches a maximal safety value, the storage battery supplies power to a base station; and if the storage electric quantity does not reach the maximal safety value, whether a solar battery module outputs electric energy is judged, if the solar battery module outputs the electric energy, the storage battery supplies power to the base station, and the solar battery module charges the storage battery; and if the solar battery module outputs no electric energy, the municipal power supplies power to the base station. By adopting a supplementary way of the solar and the municipal power, the problem that the base station cannot work normally because of the shortage of electric power can be solved; and at the same time, the running state of the power supply system can be remotely detected in real time through a solar controller, a storage battery managing unit and a remote diagnosis instrument, and the technical weakness of the prior art that manual detection is required can be overcome.

Description

technical field [0001] The invention relates to the technical field of electric power supply systems, in particular to a power supply method, a power supply controller and a power supply system. Background technique [0002] The base station needs power supply to work normally. For areas where power resources are scarce, once a power shortage or power accident occurs, it is necessary to rely on backup power to maintain the normal operation of the communication base station. For remote areas without mains power, it is even more difficult to ensure the normal operation of the base station. Only relying on backup power supply will greatly increase the cost, which severely limits communication operators to set up base stations in these remote areas. [0003] At present, most of the backup power sources used in communication base stations are lead-acid batteries, but due to the limitation of volume and capacity, the lead-acid batteries can not last long enough to provide power an...
