Description
Technical field
This utility model relates to technical field of photovoltaic power generation, particularly relates to a kind of solar DC illuminator.
Background technology
Relative to flourish photovoltaic illumination market, operation and the scene such as rescue and relief work, accident treatment in power industry, Portable mobile power source is usually needed to provide suitable electric energy to illuminator and the instrument and equipment at its scene, for the performance pursuit to portable power source high power capacity, portability, high stability, low noise, solar DC illuminator has great potential at reduction energy consumption, the raising aspect such as power supply reliability and motility.In recent years, world's photovoltaic industry and semiconductor lighting industry develop rapidly, and the solar energy and semiconductor Lighting Industry of China also quickly grows, and the solar energy and semiconductor illuminator of various models is researched and developed the most in succession.But existing photovoltaic generation is all large-scale, is unsuitable for the power supply that small-sized portability moves.
Utility model content
The purpose of this utility model is to provide a kind of solar DC illuminator, uses large-scale photovoltaic to power the technical problem of inconvenience for solving some power-shortage areas in prior art.
For reaching above-mentioned purpose, the technical scheme that this utility model is proposed is:
A kind of solar DC illuminator of the present utility model, comprising: photovoltaic module, intelligent controller, ferric phosphate lithium cell, illuminator and Sofe Switch LLC converter, wherein, the output of described photovoltaic module is electrically connected to described intelligent controller, the output of intelligent controller is electrically connected to described ferric phosphate lithium cell, and the outfan of ferric phosphate lithium cell is electrically connected to described illuminator and Sofe Switch LLC converter.
Wherein, the input of described ferric phosphate lithium cell be also electrically connected with can be ferric phosphate lithium cell charging civil power input module.
Wherein, described illuminator is D. C. Lighting installation.
Wherein, described Sofe Switch LLC converter is output as direct current.
Preferably, described Sofe Switch LLC converter is LLC resonant converter.
Compared with prior art, the solar DC illuminator of this utility model, it is ferric phosphate lithium cell charging with photovoltaic generation and civil power, exported unidirectional current by ferric phosphate lithium cell is that equipment is powered and power illuminating device simultaneously, intelligent controller can improve the efficiency for charge-discharge of ferric phosphate lithium cell, and luminous energy environmental protection is renewable.
Accompanying drawing explanation
Fig. 1 is the structural schematic block diagram of this utility model solar DC illuminator.
Detailed description of the invention
Below with reference to accompanying drawing, this utility model is given elaboration further.
Refer to accompanying drawing 1, this solar DC illuminator, comprising: photovoltaic module 1, intelligent controller 2, ferric phosphate lithium cell 3, illuminator 5 and Sofe Switch LLC converter 6.Wherein, the output of described photovoltaic module 1 is electrically connected to described intelligent controller 2, and the output of intelligent controller 2 is electrically connected to described ferric phosphate lithium cell 3, and the outfan of ferric phosphate lithium cell 3 is electrically connected to described illuminator 5 and Sofe Switch LLC converter 6.Under conditions of having civil power supply, the input of described ferric phosphate lithium cell 3 is also associated with a civil power input module 4, and directly using civil power is that ferric phosphate lithium cell 3 charges.
Wherein, described illuminator 5 is D. C. Lighting installation, and described Sofe Switch LLC converter 6 is output as direct current.Concrete, described Sofe Switch LLC converter is LLC resonant converter.
Research shows, lithium ion battery charge cutoff voltage is the highest, and electrokinetic cell cycle life is the shortest；Temperature is the highest, and single-unit electrokinetic cell capacity attenuation is the fastest.The cycle life of electrokinetic cell is also had an impact by the connected mode of power battery pack and putting position and charge-discharge magnification etc., so the charging of accumulator, it is necessary to carrying out protection of transfiniting, ferric phosphate lithium cell uses the method that constant current combines with constant voltage.When battery is first with constant current charge, cell voltage raises in time, reaches 3.65V once cell voltage, i.e. transfers to and continues charging under constant 3.65V voltage.Under constant voltage, charging current declines in time, when electric current drops to certain numerical value, can stop charging, and be considered as charging complete.Selecting above-mentioned charging method is to be determined by the inherent character of ferric phosphate lithium cell itself, because ferric phosphate lithium cell does not have the additives for overcharge protection mechanism often having in aqueous electrolyte accumulator.Once overcharge, not only on positive pole due to deintercalation too much lithium recurring structure irreversible change, negative pole is likely to be formed lithium metal surface separate out；And it may happen that the side reactions such as the decomposition reaction of barrier film.Thus cause the rapid attenuation of battery cycle life.
Battery, the most also can be damaged without discharge prevention.When voltage arrives the minimum discharge voltage set, controller can automatically cut off load to protect battery not by overdischarge.When solar panel reaches when being again started up voltage of controller setting to the charging of accumulator, and load just can be turned on again.
Connect between the loop of accumulator a resettable fuse, effectively accumulator has been carried out overcurrent protection, reduced Breakdown Maintenance, saved human cost.
Therefore, ferric phosphate lithium cell 3 is needed to add intelligent controller 2.This intelligent controller 2 can be charged regulation according to the practical situation of ferric phosphate lithium cell 3.
Wherein, ferric phosphate lithium cell has the advantage that the life-span of overlength: the electrokinetic cell with LiFePO4 as positive electrode, cycle life is up to more than 2000 times.Fast charging and discharging: can be with 2C big electric current fast charging and discharging.Use safety: even if ferric phosphate lithium cell also will not produce blast in worst vehicle accident, through strict safety test.High temperature resistant: lithium manganate battery and cobalt acid lithium battery electric heating peak value can only be at about 200 DEG C, and ferric phosphate lithium cell electric heating peak value is up to 350 DEG C～500 DEG C.Lighter in weight, small volume.The volume of the ferric phosphate lithium cell of equivalent capability specification only has the 2/3 of lead-acid battery, and weight only has the 1/3 of lead-acid battery.
Foregoing; it is only preferred embodiment of the present utility model; it is not intended to limit embodiment of the present utility model; those of ordinary skill in the art are according to central scope of the present utility model and spirit; corresponding flexible or amendment can be carried out very easily, therefore protection domain of the present utility model should be as the criterion with the protection domain required by claims.
