In communication, meteorological industry, the powerup issue of remote website mainly adopts solar electric power supply system, and solar electric power supply system mainly is made up of solar components, solar charging/discharging controller, storage battery three parts.The battery-operated ambient temperature is when being lower than-10 ℃, and battery has the risk that was lost efficacy by bursting by freezing.Along with the reduction of temperature, the electrolyte in the storage battery solidifies gradually, and its available capacity significantly descends, and generally speaking, during temperature-10 ℃, the charge in batteries ability is merely 40% of 25 ℃ of normal temperature.When being lower than-30 ℃, solar components can't charge a battery.Therefore, at high temperature and extremely frigid zones, accumulators provides a comparatively desirable operational environment, ensures that the electric power system operate as normal seems particularly important.
At present, solving the common method that storage battery can not charge under the low temperature environment is that employing is buried, utilizes the comparatively constant characteristics of certain depth temperature under the face of land, comparatively desirable operational environment is provided for the battery in high temperature and cold district use.But buried have a born drawback: because embedding for a long time, earth pressure causes the guard box distortion, can't accomplish excellent waterproof; The site operation amount is big and complicated; Battery service is changed complicated.In addition, part adopts the battery charging plant that adds thermal control, adopts thermostatically controlled mode, causes the waste of rechargeable energy, influences charge efficiency.
The utility model content
In order to overcome the waste that the thermostatic control of existing storage battery charging device causes rechargeable energy; Influence the deficiency of charge efficiency; The utility model aims to provide a kind of low-temperature storage battery charging heater, and this device can be implemented in high efficiency under the low temperature environment, the charging of low energy consumption ground.
To achieve these goals, the technical scheme that the utility model adopted is: said low-temperature storage battery heating charging device comprises solar components, the charging-discharging controller that links to each other with solar components, and the storage battery that is electrically connected with this charging-discharging controller; Its design feature is, said storage battery places in the incubator, is provided with heating element between the bottom of this storage battery and the incubator, and this heating element is electrically connected with said charging-discharging controller through power line.
Be provided with the temperature sensor that detects the accumulator meter surface temperature between the sidewall of said storage battery and incubator.
Said heating element is preferably silicon rubber heating plate or silicon rubber heater strip, and this silicon rubber heating plate links to each other with charging-discharging controller through power line, and this charging-discharging controller is built-in with heater switch.This charging-discharging controller links to each other with storage battery, solar components, and charging-discharging controller judgement charge efficiency and temperature are controlled heating element.
In order to improve the heat insulation effect of incubator, keep the accumulator meter surface temperature, be filled with insulation material in the said incubator wall body.
Be provided with the protected by temperature limitation switch that when temperature sensor detection accumulator meter surface temperature is higher than 40 degrees centigrade, stops to heat in the said charging-discharging controller, surpass 40 ℃, then cut off the power supply of heating element in case temperature sensor detects the accumulator meter surface temperature.
By said structure, when storage battery charges, judge through charging-discharging controller whether rechargeable energy is all absorbed by storage battery; If absorption efficiency is lower than and is provided with a little, the said temperature sensor of incubator inwall that places detects the storage battery hull-skin temperature, is lower than charge in batteries critical temperature point; Charging-discharging controller starts; The heating element heating after the heating set time, repeats above-mentioned steps again.If charge efficiency is higher than and is provided with a little, rechargeable energy is absorbed by storage battery, and charging-discharging controller cuts off the heating element power supply, stops heating.That is, the solar charging/discharging controller judges whether the energy of solar components conversion is all absorbed by storage battery, and temperature sensor detects the critical temperature point, turn-offs heating element through heating control circuit.
When the utility model detected heating-up temperature above safety value at temperature sensor, charging-discharging controller cut off the heating element heating.
Compared with prior art, the beneficial effect of the utility model is: the utility model detects charge in batteries efficient in real time under low temperature environment; Having improved solar components is the charge efficiency of storage battery; Reduce the loss of rechargeable energy, had advantage simple in structure, easy to operate simultaneously.Be adapted to especially that solar components is the charge in batteries needs under the open-air low temperature environment.
Below in conjunction with accompanying drawing and embodiment the utility model is done further to set forth.
