The utility model is characterized in that the positive pole of the solar energy battery pack is electrically connected with the positive pole of the charging battery by an inductance coil and a diode, the negative pole of the solar energy battery pack is directly and electrically connected with the negative pole of the charging battery, a capacitor is connected in parallel between the positive pole and the negative pole of the charging battery, and a switch type voltage stabilizing integrated circuit is connected in parallel between the positive pole and the negative pole of the solar energy battery pack. The utility model has the advantages of simple structure, small volume, low cost and convenient operation, and the utility model is not limited to the conditions. The utility model is suitable for being used as the power supply for portable electric appliances.
Description
The utility model relates to the device that is powered to the load by battery pack, specifically the charge power supply device of being made up of solar cell and rechargeable battery.
Present portable electrical appliance is general direct to be provided by battery, and as portable radio-cassette player, mobile telephone etc., the capacitance of common batteries is limited, and not reproducible utilization also easily causes environmental pollution; And rechargeable battery must have external power source is its charging, thereby is subject to condition restriction, uses very inconvenient.Chinese patent 91230448 discloses a kind of sun-generated electric power machine; mainly constitute by solar charger, storage battery protecting device, storage battery and inverter; it is characterized in that adopting in the machine active and standby two group storage batteries to switch circuit control and regularly be recharged and provide power supply by one; this device volume is bigger; complex structure; the cost height is unsuitable for portable electrical appliance.
The purpose of this utility model be to provide a kind of simple in structure, volume is little, cost is low, be suitable for the solar charging power supply that portable electrical appliance is used.
For achieving the above object, the utility model comprises solar battery group, rechargeable battery, characteristics are that the positive pole of solar battery group is connected with the positive electrical of rechargeable battery by inductance coil, diode, the negative pole of battery pack directly is connected with the negative electricity of rechargeable battery, electric capacity in parallel between the positive and negative electrode of rechargeable battery; Between the positive and negative electrode of solar battery group, switching mode integrated regulator piece in parallel, the positive and negative electrode of rechargeable battery is as the output of power supply, for electrical appliance provides power supply.After solar battery group was converted into electric energy with luminous energy, the DC-to-DC converter in integrated circuit block, mild rectifier boosted, after the rectification, output form one stably voltage load on the two poles of the earth of rechargeable battery.
When the utility model and portable electrical appliance are assembled into one, during as the power supply of this electrical appliance, charged from trend rechargeable battery by solar cell daytime, while is as the power supply of electrical appliance, night is then by the power supply of rechargeable battery as electrical appliance, do not need frequently to change battery, can not be subjected to condition influence yet, use more convenient; Because the integrated circuit block volume that the utility model adopts is little, cost is low, peripheral cell is few, thereby can not influence the volume and the cost of portable electrical appliance; Simultaneously low in energy consumption because of it, the conversion efficiency height can make the two ends of rechargeable battery keep a high voltage stably, can improve the charge efficiency of rechargeable battery and the utilization ratio of useful life and solar battery group.
Below in conjunction with accompanying drawing the utility model embodiment is specifically described:
Fig. 1 is the circuit diagram of the utility model solar charging power supply.
With reference to shown in Figure 1, the utility model comprises solar battery group 1, rechargeable battery 3, the positive pole of solar battery group 1 is connected with the positive electrical of rechargeable battery 3 by inductance coil 4, diode 2, the negative pole of solar battery group 1 directly is connected with the negative electricity of rechargeable battery 3, electric capacity 5 in parallel between the positive and negative electrode of rechargeable battery 3; Between the positive and negative electrode of solar battery group 1, switching mode integrated regulator piece 6 also in parallel, the model of this integrated circuit block is LT1173, its pin Ilim and UIN are connected between the positive pole and inductance 4 of solar battery group 1, pin SW1 is connected between inductance 4 and the diode 2, pin SENSE is connected between the positive pole of diode 2 and rechargeable battery 3, and pin GND and SW2 are connected between the negative pole of the negative pole of solar battery group 1 and rechargeable battery 3.
Described inductance 4 values are 82uh, and the value of electric capacity 5 is 100uf.
