Problems solved by technology

[0004] Although the protection device in the prior art can prevent the battery from frequent deep discharge and effectively prolong the service life, but in the dark, when over-discharge is detected, the power supply will be cut off in time, which will affect the lighting use of solar LED lights and lose the role of street lights at night.

Embodiment Construction

[0022] The present invention will be further described in detail below in conjunction with the accompanying drawings, so that those skilled in the art can implement it with reference to the description.

[0023] figure 1 An implementation form of the battery power supply control method for solar LED street lamps is shown, which includes: separately collecting voltage signals of multiple voltage dividing points of the battery; The number of groups powered in parallel. figure 1 The dotted line in is the content of the omitted charging control. In order to reduce the damage of LED lamp beads during use, you can choose the same number and type of LED lamp beads in parallel connection in each group, which is also conducive to the same power of each LED lamp bead that emits light, and a consistent luminous degree is obtained.

[0024] Taking the collection of three voltage division points of the storage battery as an example, the voltage signal of each voltage division point corre...

Abstract

The invention discloses a storage battery power supply control method for a solar LED street lamp, which comprises: respectively collecting voltage signals of a plurality of voltage division points of the storage battery; The number of groups powered. In the present invention, by separately collecting the voltage signals of multiple voltage dividing points of the storage battery, according to when the discharge of the storage battery is reduced to different degrees, LED light bead groups with different groups are connected in parallel, thereby adjusting the total load current of the storage battery and prolonging the duration of each full charge of the storage battery. The discharge time can be shortened to avoid damage to the battery due to over-discharge in the second half of the night, and reduce the probability of emergency stop due to over-discharge at night, so as to meet the needs of the light source throughout the night.

Description

technical field [0001] The invention relates to the technical field of batteries for solar LED street lamps, and more specifically, the invention relates to a battery power supply control method for solar LED street lamps. Background technique [0002] Solar street lights are powered by crystalline silicon solar cells, maintenance-free valve-controlled batteries (lithium-ion battery packs) store electric energy, super-bright LED lamps are used as light sources, and are controlled by intelligent charge and discharge controllers, which are used to replace traditional public electric lighting street lights. Street lights are conducive to safe travel at night. How to make full and reasonable use of the electric energy stored in solar cells to improve the service life of the batteries is very important. [0003] The use process and maintenance work of the battery have a great influence on the life of the battery. The battery is often deeply discharged, which affects the life of...
