Abstract
The invention relates to a solar street lamp and a storage battery group for the same, which aims to provide a storage battery group with long service life. In the invention, the storage battery group comprises a part of lithium-ion battery group and a part of plumbic-acid battery group, wherein the lithium-ion battery is used for main energy storage for the normal work of the street lamp, and the plumbic-acid battery group is used as a standby energy storage part. By the invention, the service life of the storage battery group in the solar street lamp can be effectively improved, and the increased cost is very low.
Description
Technical field
The present invention relates to solar street light and be used for the batteries of solar street light.
Background technology
Solar street light is a kind of energy-conserving and environment-protective product, can significantly reduce the consumption to the non-renewable energy, and reduces emission of carbon-dioxide; In addition; Can also reduce the peak period load of urban distribution network, not need excavated pavement, do not need cable laying, have remarkable social benefit.It is the important development direction of outdoor public illumination.
Solar street light generally is made up of lamp stand, light fixture, solar panel, batteries, electric and several parts of control module.Its operation principle is: solar panel generating on daytime, and the charging of accumulators group, supplied power to light fixture by the batteries discharge night again, thrown light on by lamp luminescence.
The light fixture of solar street light is basic now excessively to adopting the LED lamp, and it has the advantage of high-efficiency energy-saving long-life life.
That the electric control unit of solar street light possesses is light-operated, time control, over-charge protective, cross multiple functions such as putting protection and reverse connecting protection.
What the batteries of solar street light generally adopted at present is lead-acid battery group (mainly being the maintenance-free lead-acid battery group), and this mainly considers from the cost angle.In fact; The lead-acid battery group can be brought the serious environmental pollution problem on the one hand; On the other hand its service life of short duration (general 2-3; That have in addition 1 year less than tangible performance degradation promptly occurring), seriously unbecoming with the instructions for use of street lamp and the life-span of other parts of street lamp (basically all more than 10 years).This is with regard to the major defect of the reliability having brought maintenance cost is high between the operating period problem and product and show.For addressing these problems, the someone uses lithium ion battery instead as batteries, though its life-span can reach requirement, the height of its cost makes that this scheme is difficult to carry out.
Summary of the invention
To the problems referred to above; The present invention is intended to propose a kind of scheme of new batteries; Can solve battery short, big, the heavy-polluted problem of later maintenance expense in service life that the prior art scheme uses lead-acid accumulator to bring, its cost can be accepted and digested again by market.
Technical scheme of the present invention is; Employing mixes the batteries of forming by a part of lithium ion battery group and a part of lead-acid battery group; Batteries as solar street light; When the accumulators group was charged, lead-acid batteries was preferentially charged, and when its charging ends, forwarded to the lithium ion battery group again and charged; During the batteries discharge, lithium ion battery group preferential discharge is restarted the lead-acid batteries discharge when its discharge ends.
Among the present invention, the active material of the positive pole of used lithium ion battery is one or more the mixing in the following material: LiFePO4, LiMn2O4, ternary (manganese cobalt nickel) or binary (manganese nickel) composite etc.
Among the present invention; In lithium ion battery group and the common batteries of forming of lead-acid battery group; The rated energy of lithium ion battery group is one in this street lamp catabiotic 100%-200% in evening; That more excellent is 120%-150%, and the lead-acid battery group constitutes remaining storage battery energy requirement of design.
Solar street light of the present invention comprises solar street light, solar energy garden lamp, solar lawn lamp, Square Lamp and wind-solar complementary type street lamp, garden lamp, Lawn lamp, Square Lamp etc.
Adopt scheme of the present invention; In the solar street light use; Long-life lithium ion battery group is born the main daily task that discharges and recharges, and short-life lead-acid battery group mainly plays auxiliary and subsequent use effect, and the time that makes the lead-acid battery group be in the discharge attitude significantly reduces; Improved the life-span of lead-acid battery effectively, thereby improved greatly the life-span of whole solar street light batteries.
Adopt scheme of the present invention; Owing to have only the less that part of employing lithium ion battery group of bearing normal energy storage task of accounting in the batteries; And that part of lead-acid battery group that still adopts of the effect of energy storage in support that accounting is bigger in the batteries, this makes that the increase of cost is not very big.
The specific embodiment
Illustrate embodiment of the present invention below.
Embodiment one
Solar street light for 30 watts of two-way (totally 60 watts); Select for use Wp160 watt solar panel, the total energy of batteries is 2400Wh, wherein; The energy that with the LiFePO4 is anodal lithium ion battery group is 500Wh, and the energy of lead-acid battery group is 1900Wh.Street lamp adds up lighting hours every night need be full load 7 hours (8:00 opens like evening, and night, 11:30 closed 1 tunnel, and morning, 4:30 opened 2 tunnel, and morning, 5:30 closed).Solar panel generating on daytime and the charging of accumulators group; Preferentially to the charging of lead-acid battery group, when charging to the cut-off condition of lead-acid battery group, turn to the lithium ion battery group and charge during charging; When reaching the cut-off condition of lithium ion battery group, turn to again to the little electric current floating charge of lead-acid battery group.By the lithium ion battery group preferential discharge in the batteries, make the lamp luminescence illumination night, when lithium ion battery is discharged to cut-off condition, starts the discharge of lead-acid battery group.
