Abstract
The utility model relates to an insufficient electric quantity warning device for a power lithium battery. The device comprises an electric quantity detection device connected with the power lithium battery and a display device which is connected with the electric quantity detection device and is used for warning the electric quantity of the power lithium battery, and is characterized in that: the display device is a signal lamp with a flashing function; and a buzzer for warning the electric quantity of the power lithium battery is connected to the electric quantity detection device. The utility model has the advantages that: the device has a simple structure and can effectively perform insufficient electric quantity warning on a user; and therefore, the service life of the battery is prolonged.
Description
Technical field
The utility model belongs to battery electric quantity caution technical field, particularly relates to a kind of power shortage alarming device of dynamic lithium battery.
Background technology
Lithium battery obtains widespread usage with its distinctive performance advantage in portable electronics such as laptop computer, video camera, mobile communication.The high-capacity lithium battery of exploitation has begun to try out in electric automobile at present, and expectation will become one of major impetus power supply of 21 century electric automobile, and will be applied aspect artificial satellite, Aero-Space and the energy storage.Pressure along with the environmental protection aspect in the in short supply and world of the energy.The lithium electricity is widely used in the electric motor car industry now, and the particularly appearance of LiFePO 4 material battery has more promoted the development and the application of lithium battery industry.Dynamic lithium battery is to be widely used in the electric motor car industry battery that power is provided for electric motor car at present.
Because the chemical characteristic of lithium metal is very active; Make that the instructions for use of lithium battery is very high; Lithium battery should not be overcharged, overdischarge and overcurrent, short circuit discharge and recharge; The overdischarge of low-voltage or self discharge meeting cause the lithium ion active material to decompose destruction, and not necessarily can reduce, and shorten the useful life of dynamic lithium battery.In order to address the above problem, dynamic lithium battery generally connects the electric quantity detection apparatus that is used to detect battery electric quantity in use on it; After electric quantity detection apparatus detects the dynamic lithium battery power shortage, send the power shortage signal to the display unit that is connected with electric quantity detection apparatus, the user can learn battery power shortage and charging in time through display unit; But; Display unit of the prior art is generally the signal lamp of Chang Liang, is difficult for causing user's attention after signal lamp lights, especially as far as being absorbed in the user who drives; Can unconsciously shorten the useful life of lithium battery, increase the battery use cost.
Summary of the invention
The utility model for solve the technical problem that exists in the known technology provide a kind of simple in structure, can effectively carry out the power shortage caution to the user, thereby prolong the power shortage alarming device of the dynamic lithium battery in battery useful life.
The technical scheme that the utility model is taked for the technical problem that exists in the solution known technology is: a kind of power shortage alarming device of dynamic lithium battery; Comprise the display unit that the electric quantity detection apparatus that is connected with dynamic lithium battery, the electric weight to dynamic lithium battery that is connected with electric quantity detection apparatus are warned; It is characterized in that: said display unit is the signal lamp with flashing function, connects the buzzer that the electric weight of dynamic lithium battery is warned on the said electric quantity detection apparatus.
The utility model can also adopt following technical scheme:
Said signal lamp is the light-emitting diode with flashing function.
Advantage and the good effect that the utlity model has are: signal lamp and buzzer that the utility model utilization has flashing function replace the normal bright signal lamp in the conventional art; When electric quantity detection apparatus detects the dynamic lithium battery power shortage; The signal lamp of flicker can be effectively to the caution user with the buzzer that sends caution sound; The user can in time charge to lithium battery; Avoid occurring, can effectively prolong the useful life of battery because of overdischarge causes the situation that the active material decomposition destroys in the battery.
Description of drawings
Fig. 1 is the catenation principle figure of the utility model.
Embodiment
For further understanding summary of the invention, characteristics and the effect of the utility model, the following examples of giving an example now, and conjunction with figs. specifies as follows:
See also Fig. 1, a kind of power shortage alarming device of dynamic lithium battery.Comprise that electric quantity detection apparatus carries out the display unit of power shortage caution with the signal that can accept electric quantity detection apparatus that is connected with electric quantity detection apparatus and to dynamic lithium battery.The dedicated test chip that electric quantity detection apparatus is well known to those skilled in the art, display unit are the signal lamp with flashing function.Except that above-mentioned signal lamp, also connect the buzzer that the electric weight of dynamic lithium battery is warned on the electric quantity detection apparatus.Electric quantity detection apparatus detects after the dynamic lithium battery power shortage; Send signal to connected signal lamp and buzzer; Signal lamp flicker time buzzer sends caution sound, can remind effectively that the user is a battery charge, thereby avoids shortening the useful life of battery.
In the present embodiment, signal lamp is the light-emitting diode with flashing function.
Claims (2)
1. the power shortage alarming device of a dynamic lithium battery; Comprise the display unit that the electric quantity detection apparatus that is connected with dynamic lithium battery, the electric weight to dynamic lithium battery that is connected with electric quantity detection apparatus are warned; It is characterized in that: said display unit is the signal lamp with flashing function, connects the buzzer that the electric weight of dynamic lithium battery is warned on the said electric quantity detection apparatus.
2. the power shortage alarming device of dynamic lithium battery according to claim 1, it is characterized in that: said signal lamp is the light-emitting diode with flashing function.
