Description of drawings
Fig. 1 is the structural representation of the Vehicular solar charging system for electric automobile of the present invention.
Embodiment
The invention will be further described below in conjunction with accompanying drawing.
See also Fig. 1, electric automobile comprises battery 100, Vehicular solar charging system for electric automobile of the present invention, comprise solar panel 1, DC/DC converter 2, first resistance R 1, electric current warning circuit 3, voltage comparator 4, temperature sensor 5, A/D converter 6, DSP7 and display screen 8, wherein:
The electric current warning circuit comprises second resistance R 2, LED lamp D and metal-oxide-semiconductor K;
One end of second resistance R 2 connects the end that joins of DC/DC converter 2 and first resistance R 1, and the other end of second resistance R 2 connects the drain electrode of metal-oxide-semiconductor K by LED lamp D;
The source ground of metal-oxide-semiconductor K;
The positive input terminal of voltage comparator 4 connects the end that joins of LED lamp D and second resistance R 2, and the negative input end of voltage comparator 4 connects the end that joins of first resistance R 1 and battery 100, and the output of voltage comparator 4 connects the grid of metal-oxide-semiconductor K.
Operation principle of the present invention: solar panel 1 is converted to direct current energy with solar energy, after DC/DC converter 2 is handled, gives battery 100 chargings by first resistance R 1; When being big electric current, because first resistance R 1 is precision resister, the pressure drop that causes is bigger, makes "+" input and "-" input potential difference greater than particular value, and voltage comparator 4 is input as height, and metal-oxide-semiconductor K blocks, and LED lamp D does not work; When being little electric current, "+" input and "-" input potential difference be less than particular value, and this moment, voltage comparator 4 was output as lowly, and metal-oxide-semiconductor K connects, and the LED lamp is bright, and prompting disconnects charging.Temperature sensor 5 is gathered the temperature of battery 100 in real time, and the temperature signal of output converts digital signal to through A/D converter 6, and this digital signal shows at display screen 8 that by DSP7 when temperature was too high, prompting disconnected charging.
In the present embodiment, the model that voltage comparator 4 is selected for use is LM339; The model that DSP7 selects for use is TMS320F2808.
Above embodiment is only for the usefulness that the present invention is described, but not limitation of the present invention, person skilled in the relevant technique, under the situation that does not break away from the spirit and scope of the present invention, can also make various conversion or modification, therefore all technical schemes that are equal to also should belong to category of the present invention, should be limited by each claim.
