The dual-power electric vehicle electric quantity display device can display active battery packs and standby battery packs, the LED lamp groups are longitudinally arranged on both sides of a speed meter to display electric quantities more obviously; the double-color LED lamp can display whether the battery packs are fully charged; the loudspeaker can voice-prompt the electric quantities of the active battery packs and the standby battery packs.
Description
Technical field
The present invention relates to electric automobiles, is a kind of dual power supply battery-driven car electric quantity display device specifically.
Background technology
at present, on market, general battery-driven car electric quantity display device has two kinds, and a kind of is the state of charge showing with LED lamp, and it is indicated electric weight by the light on and off of Single-chip Controlling LED lamp; Another kind is to show by instrument.But for dual power supply battery-driven car, its two groups of power supplys can be used respectively or two in parallel uses, for such battery-driven car, re-use above two kinds of electric quantity display devices and just cannot be presented at that while only using one group of power supply, another organizes the battery condition of not using power supply.
Summary of the invention
The shortcoming existing in order to overcome above-mentioned prior art, what the object of the present invention is to provide a kind of electric weight that not only shows the power supply using and use is where to organize power supply, also shows the electric weight of backup power and backup power.
In order to address the above problem, the present invention is by the following technical solutions: a kind of dual power supply battery-driven car electric quantity display device, comprise circuit card, the one LED lamp group and the 2nd LED lamp group, described circuit card is provided with micro controller system, this micro controller system is connected with the 2nd LED lamp group with a LED lamp group respectively, it is characterized in that, it also comprises the first LED display, the second LED display, the 3rd LED display, dual-colored LED lamp and loudspeaker, a described LED lamp group and the 2nd LED lamp group are separately positioned on the left and right sides of electric bicycle speed meter, in the lower end of each lamp group, the first LED display and the second LED display are set respectively, on the gauge panel of battery-driven car, be provided with " backup power " printed words, on printed words right side, be provided with successively the 3rd LED display and double-colored LDE lamp, described micro controller system is also connected with loudspeaker with the first LED display, the second LED display, the 3rd LED display, dual-colored LED lamp respectively.A described LED lamp group and the 2nd LED lamp group form by ten LED lamp longitudinal arrangements.
Described " backup power " printed words are arranged on instrument panel of electric vehicle lower right side.
Described loudspeaker are arranged on instrument panel of electric vehicle outside.
The invention has the beneficial effects as follows: it is by arranging the first LED display, the second LED display and the 3rd LED display, the battery pack that energy demonstration is being used and the state of stand by battery, in speed of a motor vehicle instrument both sides, LED lamp group is longitudinally set, electric weight is shown more obvious; The state of charge that shows stand by battery by a dual-colored LED lamp, can remind chaufeur stand by battery whether electric weight is sufficient; At instrument panel of electric vehicle arranged outside loudspeaker, can carry out voice message to the battery pack of current use and battery electric quantity.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the present invention is described further:
Fig. 1 is structural representation of the present invention;
Fig. 2 is schematic diagram of the present invention.
The specific embodiment
As depicted in figs. 1 and 2, one embodiment of the present invention comprises circuit card, the first LED display 1, the second LED display 2, the 3rd LED display 3, a LED lamp group 4, the 2nd LED lamp group 5, dual-colored LED lamp 6 and loudspeaker 7, the one LED lamp group 4 and the 2nd LED lamp group 5 are separately positioned on the left and right sides of electric bicycle speed meter 8, and the first LED display 1 and the second LED display 2 are set respectively in the lower end of each lamp group; On instrument panel of electric vehicle 9, be provided with " backup power " printed words, preferred, " backup power " printed words are arranged on instrument panel of electric vehicle 9 lower right sides, are provided with successively the 3rd LED display 3 and double-colored LDE lamp 6 on printed words right side; Circuit card is provided with micro controller system, and this micro controller system is connected with loudspeaker 7 respectively at the first LED display 1, the second LED display 2, the 3rd LED display 3, a LED lamp group 4, the 2nd LED lamp group 5, dual-colored LED lamp 6.
Preferably, a LED lamp group 4 and the 2nd LED lamp group 5 form by ten LED lamp longitudinal arrangements, and each LED etc. show 10 electric weight.
Loudspeaker 7 are arranged on instrument panel of electric vehicle 9 outsides, and it can be embedded in the shell of instrument panel of electric vehicle 9, also can directly be fixed on the casing wall of instrument panel of electric vehicle 9.
Electric weight procedure for displaying of the present invention is identical with existing battery-driven car battery capacity indication lamp principle, but it arranges respectively the first LED display 1 and the second LED display 2 in the lower end of a LED lamp group 4 and the 2nd LED lamp group 5, which Battery pack group what by Single-chip Controlling the first LED display 1 and the second LED display 2, show current use is, for example, two Battery pack groups are respectively A and B, when using A battery pack, the first LED display and the second LED display all show A, while using B battery group, show B, while using A and B battery group, show A+B; It also shows that by the 3rd LED display which group backup power is, and by dual-colored LED lamp, its electric weight is shown, when emergency battery is saturated, LED lamp is red, and when emergency battery electric weight is not enough, LED lamp is yellow; When battery electric quantity is not enough or carry out battery pack switching, loudspeaker 7 carry out voice message.
The above is the preferred embodiment of the present invention, for those skilled in the art, under the premise without departing from the principles of the invention, can also make some improvements and modifications, and these improvements and modifications are also regarded as protection scope of the present invention.
