Description
The utility model relates to a kind of solar energy accumulation power supply.
Solar energy is a kind of pollution-free green energy, and after first solar cell in 1954 came out, it was applied to space and ground more and more as a kind of new forms of energy.Because solar cell is based on photovoltaic effect; utilize inexhaustible, nexhaustible solar energy; under the condition that does not produce air pollution and environmental hazard, produce electric power; therefore after occurring from solar cell; particularly since the oil shock of 1973 crisis; many countries have all stepped up the speed of R and D solar cells, the emphasis that the development and application of novel solar battery has become various countries to fall over each other to study.Present solar cell mostly is the silicon photocell plate, and its output voltage is lower, and monomer voltage is only about 0.45 volt.Though adopt the series connection of many group silicon photocell plates can improve current potential, but can cause that process loss increases and commercial cost increases, so present solar cell is (as slim calculator etc.) except being used for the small civilian small electric apparatus of power consumption, is used in the Space Facilities resemble the satellite more.Even adopt in the civilian small electric apparatus of solar cell at those, in order to reduce cost, also all be that the direct power supply of the output of photovoltaic cell module as load used, clearly, such electrical equipment can only have under the situation of light and could use.
Can be in order fully and expediently to utilize solar energy, people to wish the electrical power storage of solar energy transformation.But because photovoltaic cell module output is that pure direct current and voltage are lower, and the electrochemical conversion efficient of pure direct current output is low, so the electric energy that photovoltaic cell module is exported directly should not be stored.
In view of above-mentioned, the purpose of this utility model just provides a kind of solar energy highly effective accumulation electrical source, and it is transformed into chemical energy with higher transformation efficiency again and stores after solar energy can being transformed into electric energy.
For reaching above-mentioned purpose, the utility model adopts following technical scheme:
The solar energy highly effective accumulation electrical source, comprise solar panel and rechargeable battery, it is characterized in that: be connected in series charger between solar panel and the rechargeable battery, this charger is made of voltage lifting circuit, impulse circuit and electronic switch, connect the output of described solar panel after voltage lifting circuit and the electronic switch series connection, the output of impulse circuit connects the control end of electronic switch, and the output of electronic switch connects described rechargeable battery through isolating diode.
In the implementing measure of technique scheme:
Voltage lifting circuit is made of inductance coil, and impulse circuit is made of oscillator, and electronic switch is a switching tube.The output of oscillator connects control end of switching tube through driver.Rechargeable battery serial connection current limiting element.
During the utility model work, impulse circuit makes electronic switch be in the intermittently state of switching, electronic switch disconnects at every turn, the capital makes voltage lifting circuit promote primary voltage,, the low-voltage DC of solar panel sends in the rechargeable battery purpose that the electric energy of having realized solar energy is changed stores with the chemical energy form thereby being transformed into the higher pulse current of voltage.
Because the utility model has adopted the mode of pulse direct current charging, thereby has improved the transformation efficiency that is transformed into chemical energy by electric energy, makes the low-cost solar accumulation electrical source become possibility; And then owing to equipped rechargeable battery in the product, so the utility model both can be used as solar charger and used, and also can use accessory power supply as under rayless situation.
Below in conjunction with drawings and Examples the utility model is elaborated.
Fig. 1 is a circuit diagram of the present utility model.
The utility model is made up of solar panel, charger and rechargeable battery, and charger and rechargeable battery are contained in the shell, and solar panel is connected with this shell.Charger is serially connected between solar panel and the rechargeable battery, this charger is made of voltage lifting circuit, impulse circuit and electronic switch, wherein: connect the output of solar panel after voltage lifting circuit and the electronic switch series connection, the output of impulse circuit connects the control end of electronic switch, and the output of electronic switch connects rechargeable battery through isolating diode.
See also accompanying drawing.Voltage lifting circuit is made of inductance coil L, electronic switch is switching tube SK, and impulse circuit is made of oscillator, this oscillator by two inverter ic 1-1 and IC1-2, corresponding resistance and electric capacity routinely connection form, SE is a silicon electro-optical package solar panel, and E is rechargeable battery (group).Connect the output of solar panel SE after inductance coil L and the switching tube SK series connection, the output of oscillator connects the control end of switching tube SK, and the output of this switching tube meets rechargeable battery E through isolating diode A.Diode A is used for preventing that rechargeable battery E from discharging to charger circuit.The direct current of exporting because of solar panel SE had both supplied charging usefulness, simultaneously again as the power supply of oscillator, so its output voltage grade should satisfy the power requirement of oscillator, selected for use the combined solar panel of exportable 1.5V to get final product herein.
During the utility model work, oscillator makes switching tube SK be in the intermittently state of switching, the every disconnection of switching tube once, the capital makes inductance coil L produce back-emf, because this back-emf is higher than the voltage of solar cell SE, thereby the low-voltage DC of solar panel output can be promoted and be transformed into the higher pulse current of voltage, and then send in the rechargeable battery.Oscillator is adjusted the inductance value of its frequency of oscillation and inductance coil L by the square-wave generator design, just can change the boosted voltage amplitude.
In addition, in order to improve the power output of charger, the output of oscillator is connect the control end of switching tube SK again after driver drives, this driver is with four inverter ic 1-3 in the hex inverter integrated circuit ... 6 formations in parallel.Excessive in order to prevent charging current, in the rechargeable battery loop, also be connected in series current limiting element, the current limiting element that adopts among the figure is a resistance R.
The utility model after tested, be that 160mA, charging interval are 4h in charging current equally, rechargeable battery is under the condition of AA type NI-CD chargeable battery, adopt the pulse direct current charging to compare with adopting pure DC charging, extend to 67min by 51min discharge time, and discharge output electric weight is brought up to 505mAh by 416mAh.
The purer direct current mode of transformation efficiency that the utility model makes electric energy change chemical energy improves 15%-20%.
It can charge to the monomer chargeable battery of NI-CD, NI-MH series, and its pulse direct current can effectively reduce the generation of NI-CD memory effect of cell.It also can charge and as auxiliary electric power supply to PACK (combination) battery, the electrical appliance portable to mobile phone, intercom, gamma camera etc. adopts back type, when illumination, solar panel can directly be powered to power circuit, its dump energy is by the PACK battery storage, under the situation of no visible light, can convert to automatically by battery pack output electric energy.Especially need the long period to move or be in the environment of no grid charging condition for electrical appliance, the utility model will show great superiority.
