Abstract
The invention discloses a solar road lamp energy-storage system which comprises a solar battery board, a storage battery, a charging and discharging controller and a capacitor, wherein the four sets of positive and negative ports of the charging and discharging controller are respectively connected with the positive and negative ports of the solar battery board, the storage battery, the capacitor and a road lamp in a corresponding way. With the adoption of the system, the electricity storage capacity can be increased, the illumination time of the road lamp can be prolonged and the service efficiency of the storage battery can be increased.
Description
Technical field
The present invention relates to solar street light, be meant the energy-storage system that electric weight is provided for solar street light especially.
Background technology
In short supply day by day along with traditional energy, solar street light obtains application more and more widely.In the solar electric power supply system; The performance quality of storage battery directly influences integrated cost and the operation quality and the useful life of system; Also should consider the useful life of storage battery in whole road lamp system is used; General storage battery guarantee 3 years or 5 years; But general storage battery the discontented situation of charging will occur after 1 year even half a year; Some actual charge rate might drop to about 50%; This will influence the normal illumination at night in continuous overcast and rainy period, so select a storage battery preferably particularly important.
In view of the too small needs that can not satisfy night lighting of battery capacity; Someone proposes the storage battery of selecting for use capacity bigger; Yet; Battery capacity is excessive; Storage battery is in the power shortage state for a long time, shortens the life of storage battery, also wastes unnecessary investment simultaneously; Therefore, this scheme does not have bigger practical significance.
In view of this, the inventor considers original storage battery on the solar street light is carried out dilatation, to improve the service efficiency of storage battery.
Summary of the invention
The object of the invention is to provide a kind of solar street light energy-storage system, and it can increase reserve of electricity, prolongs the lighting hours of street lamp, improves the service efficiency of storage battery.
In order to reach above-mentioned purpose, solution of the present invention is:
A kind of solar street light energy-storage system; Comprise solar panel and storage battery; Also comprise charging-discharging controller and capacitor, wherein 4 of charging-discharging controller groups of positive and negative ports respectively with corresponding connection of positive and negative port of solar panel, storage battery, capacitor and street lamp.
Above-mentioned capacitor adopts super capacitor.
After adopting such scheme; Whether the present invention inserts the charge/discharge loop through increasing capacitor by charging-discharging controller control, when solar panel charges when reaching capacity to storage battery; Will charge to capacitor, thus the reserve of electricity of increase energy-storage system; And when solar panel storage battery is charged do not reach capacity (owing to weather reason or other factors); Can not satisfy normal illumination during service time; Can utilize the capacitor discharge; Continue as street lamp power supply, road lamp power supply; Guarantee the lasting illumination of street lamp; Prolong the lighting hours of street lamp, improve the service efficiency of storage battery.
Description of drawings
Fig. 1 is a structured flowchart of the present invention.
Embodiment
Below will combine accompanying drawing that structure of the present invention and characteristics are elaborated.
As shown in Figure 1, the present invention provides a kind of solar street light energy-storage system, comprises solar panel and storage battery.The effect of solar panel is to be electric energy with conversion of solar energy, and storage battery then is used for saving electric weight, when sunlight is arranged, utilizes solar panel, is storage battery savings electric weight, and in the night street lighting, for street lamp provides electric energy.
Point improvements of the invention, further comprising: charge controller and a capacitor (in this embodiment a capacitor using a super large capacity capacitor), a capacitor charge and discharge controller of a group of "", "-" port, By charging and discharging the capacitor is connected and powered controller / charging circuit, when the day strong sunlight exposure, solar panels can absorb plenty of sunlight, and the battery is charged, the battery capacity is relatively easy to reach saturation, charge and discharge control controller will control the capacitor charging, thereby increasing the energy storage system storage capacity, normal street lighting at night use, the battery can provide enough power for the lights; And when the day is cloudy or rainy days, because solar panels absorb small amounts of sunlight, the solar panels will only charge the battery, the battery can not provide enough power for the lights, you can use the capacitor charge and discharge controller, to continue to supply street lights, to ensure the normal street lighting, street lighting to extend time, improve battery efficiency.
In sum, a kind of solar street light energy-storage system of the present invention focuses on capacitor is inserted charging-discharging controller, utilizes the electrology characteristic of capacitor, the reserve of electricity when increasing charging, thereby the lighting hours that prolongs street lamp, the service efficiency of raising storage battery.
Above embodiment only for explanation technological thought of the present invention, can not limit protection scope of the present invention with this, every technological thought that proposes according to the present invention, and any change of on the technical scheme basis, being done all falls within the protection range of the present invention.
