Further: described roof, front cover, after car, between the solar cell of exterior surface and power accumulator, be provided with auxiliary charging storage battery, first described solar cell is connected to auxiliary charging storage battery to auxiliary charging charge in batteries, auxiliary charging storage battery connects a straight-friendship-straight booster circuit, between straight-hand over-straight booster circuit and power accumulator, be provided with electronic switch, a unpowered driving signal of power accumulator is connected to the control end of electronic switch, when motor in electric automobile no current is inputted, described electronic switch conducting, auxiliary charging storage battery charges to power accumulator.
Further: described electronic switch is power triode, the emitter of power triode is connected to power accumulator positive pole, the collector electrode of power triode connects the positive pole of booster circuit, between the collector electrode of power triode and base stage, be connected with driving resistance, between described power accumulator and motor in electric automobile, be provided with one as the current sampling resistor of described unpowered driving signal, described sample resistance is in parallel with emitter with the base stage of a switch triode, and the collector electrode of described switch triode connects the base stage of pliotron.
The beneficial effects of the utility model are: in body of a motor car outer cover, can receive sunlit surface increases solar panel, in electric automobile during traveling and stagnation of movement, by solar panel, is automobile boost charge.The process of charging adopts non-loaded charging modes, safe and reliable, in the place that has sunlight, can be just vehicle charging, and charging is convenient, uses complete free of contamination solar energy, energy-conserving and environment-protective.Extend the cruising time of electric automobile, solved the electric motor car inconvenient problem of charging.
Below in conjunction with drawings and Examples, the utility model is described in detail.
Accompanying drawing explanation
Fig. 1 the utility model structural representation;
Fig. 2 the utility model charging circuit schematic diagram;
Fig. 3 the utility model charging circuit schematic diagram.
Embodiment
An electric automobile solar energy auxiliary charging device, as shown in Figure 1, comprises solar cell 1, and described solar cell sticks on roof 2, front cover 3, car bonnet 4 outer surfaces of electric automobile, at the outer surface of described solar cell, pastes light transmission protecting film; As shown in Figure 2, after roof, front cover, car, the solar cell of exterior surface converts solar energy to power accumulator 5 chargings of the backward electric automobile of electric energy.
In embodiment, as shown in Figures 2 and 3, for stable charging, described roof, front cover, after car, between the solar cell of exterior surface and power accumulator, be provided with auxiliary charging storage battery 6, first described solar cell is connected to auxiliary charging storage battery to auxiliary charging charge in batteries, when auxiliary charging storage battery charges to power accumulator, the voltage of auxiliary charging storage battery will be higher than the voltage of power accumulator, between auxiliary charging storage battery and power accumulator, be provided with electronic switch 7, a unpowered driving signal of power accumulator is connected to the control end of electronic switch, when motor in electric automobile no current is inputted, described electronic switch conducting, auxiliary charging storage battery charges to power accumulator.But in order there to be a stable charging voltage, first auxiliary charging storage battery connects a straight-friendship-straight booster circuit 8, and electronic switch is connected between booster circuit and power accumulator.
In embodiment: as shown in Figure 3, electronic switch is power triode, the emitter of power triode is connected to power accumulator positive pole, the collector electrode of power triode connects the positive pole of auxiliary charging storage battery or the positive pole of booster circuit, between the collector electrode of power triode and base stage, be connected with and drive resistance 9, between described power accumulator and motor in electric automobile 10, be provided with one as the current sampling resistor 11 of described unpowered driving signal, described sample resistance is in parallel with emitter with the base stage of a switch triode 12, the collector electrode of described switch triode connects the base stage of pliotron.Its operation principle is: when power accumulator drives electric motor of automobile to rotate, sample resistance 11 passes through electric current, the pressure drop forming between sample resistance 11 impels switch triode conducting to drag down the base stage of power triode, power triode ends not conducting, auxiliary charging storage battery does not charge to power accumulator, and when power accumulator is not during to electric motor of automobile output current, switch triode cut-off, now the base stage of power triode is elevated, power triode conducting auxiliary charging storage battery charges to power accumulator, and along with the booster circuit current potential of auxiliary charging storage battery declines, when approaching or equaling power accumulator voltage, power triode ends again, then booster circuit current potential rises again, and then formed a kind of pulse charging, it is a kind of desirable charging modes.
