Abstract
The utility model relates to a lithium charging battery which comprises a built-in lithium battery and a charging protection circuit. The utility model is characterized in that the input terminal of the charging protection circuit is connected with a diode. The negative pole of the diode is connected with the input terminal of a three-terminal voltage stabilizer, and the positive pole is connected with the output terminal of the voltage stabilizer. The charging battery has large capacity and reasonable structural design, and can be used for various cameras powered by two NO. 5 batteries of 1.5V, which comprises digital cameras and traditional film cameras. The utility model can also be suitable for various small household electrical appliances. The utility model can take place of NO. 5 alkali batteries, nickel-hydrogen batteries and nickel-cadmium batteries.
Description
Technical field
The utility model relates to a kind of lithium rechargeable batteries.
Technical background
Common alkaline battery capacity is little, and can only use once, and the integrated cost height is not only bad for people's use and cause environmental pollution, ni-mh and nickel-cadmium chargeable battery output voltage low (two just 2.4V in parallel), and inefficiency.Though the output voltage of conventional lithium battery be 3.6V, mostly the voltage of the camera battery of daily people's use is 3V, thereby it is improper to be made for power supply.
Summary of the invention
The purpose of this utility model is: a kind of lithium rechargeable batteries is provided, and its not only applicable working power of making camera, and also capacity is big, and the use of can charging repeatedly, thereby reduce user's spending.
The utility model is to constitute like this; comprise built-in lithium battery and charge protector; it is characterized in that: the input of described charge protector is connected to diode; the negative pole of described diode is connected with the input of a three terminal regulator, and the positive pole of diode is connected with the output of pressurizer.
Than existing lithium battery; remarkable advantage of the present utility model is: added low differential pressure on the charging and discharging protective circuit of inside battery; the 3v integrated regulator of low-power consumption; thereby the discharge voltage that makes battery is stabilized in 3v output, has solved conventional lithium battery and can not be suitable for the problem of making the camera power supply.In addition, the use because this rechargeable battery can charge repeatedly, so saved user's spending, its profile adopts human oriented design, structure is simpler, will make most camera on the market can both be suitable for this battery.
Description of drawings
Fig. 1 is the utility model embodiment one circuit theory diagrams.
Fig. 2 is the utility model embodiment two circuit structure diagrams.
Fig. 3 is the external view of the utility model embodiment two.
Embodiment
With reference to Fig. 1; the utility model embodiment one comprises built-in lithium battery and charge protector; it is characterized in that: the input of described charge protector is connected to diode; the negative pole of described diode is connected with the input of a three terminal regulator, and the positive pole of diode is connected with the output of pressurizer.Described pressurizer is low differential pressure, the 3V circuit of three-terminal voltage-stabilizing integrated XC6203 of low-power consumption.
Among Fig. 1, BATTERY is built-in lithium battery, special charging protection integrated circuit DW01 and peripheral cell R1, and R2, C1, C2, M1, M2 constitutes the charge protector to internal battery.
When need be to built-in battery charge, VBAT+ is connected with the anode of external power source, and VBAT-is connected with the negative terminal of external power source, low pressure reduction, the 3v integrated regulator XC6203 of low-power consumption is by diode SS19 bypass, charging voltage and electric current by SS19 to built-in lithium cell charging.
When needs were externally powered, with this lithium rechargeable batteries camera of packing into, then the VBAT+ VBAT-that is connected with the anode of external loading was connected with the negative terminal of external loading, and the voltage at diode SS19 two ends is anti-phase bias voltages, and this diode is by not conducting.Built-in lithium battery is through low differential pressure, and the stable 3V voltage of 3v integrated regulator XC6203 output of low-power consumption uses for camera.
The structural feature of the utility model embodiment two is: described charge protector; diode and pressurizer and internal battery are made one; described internal battery is made up of two 3.6V lithium batteries that are in parallel, and two electrodes of described lithium rechargeable batteries are positioned on the same end face of cell body.Embodiment two is because the contour structures of battery is reasonable, make on the market most of cameras can both use (can be suitable for this battery various cameras battery window as shown in the figure), not only can be widely used in by two battery powered various cameras of No. 5 1.5v (comprising digital camera and traditional film camera), also applicable to various small household electrical appliances, alternative No. five alkaline batteries and ni-mh, nickel-cadmium chargeable battery.
The utility model is not only novel, and is reasonable in design, and battery capacity is big, of many uses, has bigger application value.
