Description

A kind of device of solar energy lithium battery streetlamp photo-thermal auxiliary heating
Technical field
The invention belongs to solar energy Based Intelligent Control technical field, it is mainly used in the solar street light with lithium battery in low temperature The control device of lithium cell charging temperature is controlled under environment in the way of photo-thermal auxiliary heating.
Background technology
Solar street light increasingly photovoltaic application in the photograph in the places such as urban road, industrial park, greenbelt, square In bright, it has had the advantage that：Cable laying cost is saved, electricity usage cost is saved.With lithium battery technology develop, its into This is more and more ripe with charging management system, and the place's energy device as solar street light has larger advantage, its energy density About 120 ~ 200Wh/kg, and traditional lead-acid accumulator energy density is generally 40Wh/Kg.This causes that solar street light is small-sized Change, it is integrated to be possibly realized.
But lithium battery has an obvious shortcoming, at low temperatures, the charge and discharge of lithium battery compared with traditional lead-acid battery Electrical property is significantly lower than lead-acid battery.This is that have by the characteristic of lithium battery electrolytes is determined.The electrolyte of lithium battery is General organic solvent, the electrolyte lithium salt by high-purity of electrolyte（Lithium hexafluoro phosphate, LiFL6）, the raw material such as necessary additive, These are all low-viscosity (mobile) liquids, are easily condensed at low temperature, and electric conductivity declines；
On the other hand, in same system, in the case of the multiple lithium batteries of series connection, lithium battery due to the inhomogeneities of temperature, very Capacity is easily caused, internal resistance is mismatched, and causes battery pack to fail.Solar street light is such as installed on colder area, lithium battery Influenceed by low temperature, capacity and life-span all drastically degrade, particularly in charging process, battery is easily caused under low temperature condition Irreversible damage.So, it is very crucial that the equalized temperature of lithium battery is managed for its service life.
The device that solar street light receives energy is photovoltaic solar panel, but actually except solar panel is subject to light According to outer, lamp stand, lampshade can receive solar irradiation.And use photo-thermal using solar energy heating most effective way Mode, current light heat pipe has reached 60% to 80% using the photo-thermal conversion efficiency of solar energy, and the photoelectricity of solar cell turns Change efficiency and be generally 20%, so, the lithium battery under cryogenic conditions is heated using photo-thermal directly, it is maximally effective method.
The content of the invention
The present invention solves the technological difficulties that lithium battery charges at low ambient temperatures, using a kind of solar energy lithium battery streetlamp light The device of heat auxiliary heating, utilizes the installation collection thermosphere on solar street light upper lamp shade to collect heat, by leading in low-temperature condition Thermal and attemperating unit make lithium battery remain at the working temperature, to prolong solar street light lithium battery heated protective The service life of lithium battery long.
A kind of device of solar energy lithium battery streetlamp photo-thermal auxiliary heating of the present invention, it is characterised in that：Including sun energy circuit The metal materials such as lamp lamp stand, lampshade or solar cell frame, collection hot material, thermal-collecting tube, heat conducting pipe, heat conducting pipe magnetic valve, heat Circulation plates.Its mounting means is：Thermal-collecting tube is welded on metal material surface, and collection hot material is attached to thermal-collecting tube and metal material On, thermal-collecting tube connection heat conducting pipe, heat conducting pipe connection thermal cycle plate, electromagnetic valve are arranged on heat conducting pipe.It is achieved in that： Under low temperature condition, if the Temperature numerical that sensor detection obtains lithium battery hot surface is less than setting value, on heat conducting pipe Magnetic valve open, produce heat on the collection hot material that solar irradiation is mapped to, be transmitted to installed in lithium by thermal-collecting tube, heat conducting pipe In the thermal cycle plate of battery pack, there is provided overheat circulation plates heat up and lithium battery is preheated, when the detection of lithium battery temperature control sensor When reaching a certain setting value to battery temperature, heat conducting pipe closed electromagnetic valve, heat transfer stops, and opening controller is carried out to lithium battery Charge.
