Abstract
The utility model discloses a solar energy street lamp energy storage system, comprising a solar energy battery board, a storage battery, a charging and discharging controller and a capacitor, wherein the four groups of positive and negative ports of the charging and discharging controller are respectively and correspondingly connected with the solar energy battery board, the storage battery, the capacitor and the positive and negative ports of the street lamp. The solar energy street lamp energy storage system can enable the electric energy storage capacity to be increased, the lighting time of the street lamp to be prolonged and the usage efficiency of the storage battery to be increased.
Description
Technical field
The utility model relates to solar street light, is 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, and 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, the 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 design people considers original storage battery on the solar street light is carried out dilatation, to improve the service efficiency of storage battery.
The utility model content
The purpose of the utility model 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, the solution of the utility model 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 utility model 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; Capacitor discharge capable of using continues as street lamp power supply, road lamp power supply, guarantees 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 the structured flowchart of the utility model.
Embodiment
Below will combine accompanying drawing that the structure and the characteristics of the utility model are elaborated.
As shown in Figure 1, the utility model 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.
The improvement of the utility model is: also comprise charging-discharging controller and capacitor (capacitor in the present embodiment adopts the bigger super capacitor of capacity); Capacitor is connected with a group "+", "-" port in the charging-discharging controller; Whether insert the power supply/charge loop through charging-discharging controller control capacitance device, under sunlight acute irradiation on daytime, solar panel can absorb sufficient sunlight; And storage battery charged; Then battery capacity is easier to reach capacity, and charging-discharging controller will charge by the control capacitance device, thereby increases the reserve of electricity of energy-storage system; In street lamp normal illumination at night was used, storage battery can be street lamp enough electric weight is provided; And be cloudy day or rainy day when daytime, because solar panel absorbs a spot of sunlight, then solar panel is only understood accumulators and is charged; Storage battery can not provide enough electric weight for street lamp; Charging-discharging controller control capacitance device then capable of using continues as street lamp power supply, road lamp power supply, guarantees the normal illumination of street lamp; Prolong the lighting hours of street lamp, improve the service efficiency of storage battery.
In sum, a kind of solar street light energy-storage system of the utility model focuses on capacitor is inserted charging-discharging controller; Utilize the electrology characteristic of capacitor; Reserve of electricity when increasing charging, thereby the lighting hours that prolongs street lamp, the service efficiency of raising storage battery.
Above embodiment is merely the technological thought of explanation the utility model; Can not limit the protection range of the utility model with this; Every technological thought that proposes according to the utility model, any change of on the technical scheme basis, being done all falls within the utility model protection range.
