Abstract
The utility model discloses a solar rechargeable battery, and belongs to the field of solar energy utilization. The solar rechargeable battery comprises a rechargeable battery and a solar cell. The solar cell is arranged outside the rechargeable battery. A charging circuit is arranged between the rechargeable battery and the solar cell. The solar rechargeable battery has the remarkable advantages of high working voltage, high energy density, low self-discharge rate, no memory effect and the like; a thinner and smaller battery with any area, any shape and any capacity can be manufactured; and the thin film solar cell is arranged outside the rechargeable battery, and can be manufactured to form a housing of a lithium rechargeable battery, so that an outer package material can be saved, and the solar rechargeable battery is light, handy and convenient to carry.
Description
Technical field
The utility model belongs to field of solar energy utilization, relates in particular to the rechargeable battery that utilizes solar recharging.
Background technology
No. 1 of the prior art, No. 5, No. 7 and other standard universal batteries, owing to can only use by single, waste battery is thrown out without care and is caused environmental pollution after using up, the general rechargeable battery that has must use charger to charge, and is inconvenient to carry.
The utility model content
In order to overcome the deficiency of prior art; The utility model provides a kind of solar energy charging battery; Comprise rechargeable battery, solar cell, it is characterized in that: said rechargeable battery outside is provided with solar cell, is provided with charging circuit between said rechargeable battery and the said solar cell.
As preferably, described rechargeable battery is a lithium ion battery.
As preferably, described solar cell is a thin-film solar cells.
As preferably, be provided with the protection loam cake above the described charging circuit.
As preferably, said charging circuit is provided with charging indicator light.
Compared with prior art; The advantage of the utility model is: the lithium rechargeable batteries operating voltage is high, remarkable advantages such as energy density is big, self-discharge rate is low, memory-less effect; And battery can be done thinner forr a short time; And arbitrary areaization and arbitrary shapeization, can make the battery of Any shape and capacity; The outside is provided with thin-film solar cells, can make the shell of lithium rechargeable batteries, saves housing material; And lightly be convenient for carrying; Both can be when electrical appliance be non-electric after the connection of overcharge circuit, rechargeable battery is placed under the sun at any time charges.
Description of drawings
Fig. 1 is the stereochemical structure decomposing schematic representation of the utility model.
In Fig. 1, structure number is following: the 1-rechargeable battery; The 2-solar cell; The 3-charging indicator light; The 4-charging circuit; 5-protects loam cake.
Embodiment
Sketch map according to shown in Figure 1 further specifies the utility model; Solar energy charging battery is that the outside of rechargeable battery 1 is provided with solar cell 2 and processes; Said rechargeable battery 1 is a lithium rechargeable batteries, and said solar cell 2 is thin-film solar cells, is provided with charging circuit 4 between said rechargeable battery 1 and the said solar cell 2; Said rechargeable battery 1 is cylindric; An end that has lug boss is an anode, and said charging circuit 4 is arranged on the anode tap of said rechargeable battery 1, and a lead of said charging circuit 4 is connected with the anode of said rechargeable battery 1; Another root is connected with the negative electrode of said rechargeable battery 1; Anode tap at said rechargeable battery 1 is provided with a protection loam cake 5, also protects loam cake 5 to be provided with a charging indicator light 3 and is connected with described charging circuit 4, and said solar cell 2 is wrapped in said rechargeable battery 1 outer surface.
Its operation principle is following, and when rechargeable battery 1 voltage was lower than 0.8 volt, charging circuit 4 utilized remaining power supply to send pulse signal to charging indicator light 3; With per second frequency scintillation once; Indication rechargeable battery 1 electric weight residue is not enough, and when rechargeable battery 1 voltage was 0.5 volt, charging circuit 4 broke off rechargeable battery 1 output; Charging indicator light 3 stops dodging, with 1 overdischarge of protection rechargeable battery.When rechargeable battery 1 places solar radiation; Solar cell 2 output voltage to the charging circuit 4 of exposing to sunlight; Charging circuit 4 charges voltage and current stabilization to rechargeable battery 1, at this moment, charging circuit 4 sends pulse signal to charging indicator light 3; With per three seconds frequency scintillations once, the expression charging was underway.When charging circuit 4 detection rechargeable batteries 1 voltage arrives 1.4 volts, stop charging, at this moment, charging indicator light 3 stops flicker, and the expression electric weight is full of, and accomplishes one time charging process.
