本発明は始動電動機の駆動あるいは点燈などの電源とし
【の蓄電池を備えた自動車用電気装置に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an electrical device for an automobile equipped with a storage battery as a power source for driving a starter motor or lighting a light.

く、自動車使用の上で無視することのできない問題点で
ある。The storage battery installed in a car can be used for a long period of time (once for 2 hours)1
If you leave it for 1L, the remaining capacity will drop below the self-emission tK, and you will be unable to start unless you recharge. Such situations occur more often than expected and are a problem that cannot be ignored when using a car.
本発明はこのような烏己放電による残存容量の低下のた

供することを目的とする。An object of the present invention is to provide an electrical device for an automobile that is free from the possibility of becoming unable to start due to a decrease in remaining capacity due to such self-discharge.

らなる。The purpose of this is to attach a solar cell to a part of the car body, connect the solar cell to the anodes and cathodes of the storage battery mounted on the car KM, and connect a backflow prevention diode to one of the connection circuits. This is achieved through TotoK. Furthermore, it is desirable that an overcharge prevention circuit be inserted between the solar cell and the storage battery. The overcharge prevention circuit includes, for example, a Zener diode connected in parallel to both poles of the solar cell.

太陽電池４の出力によっても充電される。The present invention will be described below with reference to the drawings. In the electrical device for an automobile shown in FIG. 1, the output of an alternator 1 driven by the rotation of the engine is rectified by a rectifier circuit 2 to charge a storage battery 3. It is regulated by a built-in voltage regulator to prevent overcharging of the storage battery.Furthermore, a solar cell 4 is connected in parallel with the generator.The solar cell 4 is attached to the car body, for example, the roof of the car body, which is susceptible to solar radiation. In this case, since the anode of the solar cell 4 is connected to the anode of the storage battery, and the anode is connected to the anode of the storage battery 3, the storage battery 3 is also charged by the output of the solar cell 4.

上の電圧が蓄電池に加わらないようにする。However, when the vehicle '1 runs at night or in a tunnel, the output of the solar battery 4 is lost and the storage battery 3 discharges through the solar battery 4, and there is a risk that the solar battery will be destroyed. A backflow prevention diode 5 is connected between the two. Also, since the voltage and current generated by a solar cell vary depending on the amount of incident sunlight, in order to prevent overcharging of the storage battery 3, for example, a Zener diode 6 is connected in parallel to prevent voltage exceeding a predetermined value from being applied to the storage battery. .

占めるだけで十分である。The self-discharge of a storage battery is 1 to 291 for a new storage battery.
It is said that /day. If this is a maximum of 2, then 5
For a 0AH storage battery, it is IAH/day@degree. The average amount of solar radiation per day is 4 when converted to AMI light incidence.
hr, so under AMI 250ssA/12
If a V@degree solar cell is used as the solar cell 4 in Fig. 1, even if the generator 1 does not operate at all, that is, even if the car engine is stopped, the self-discharge of the storage battery will be absorbed by the output of the solar cell 4. can be supplemented. Solar voltage using amorphous silicon produced by glow discharge decomposition of silane gas on a stainless steel substrate has an optimal operating voltage of 0.6.
V, and the output current is about A/m, so 2
An output of 50 mA/12 V can be obtained by connecting 20 solar cells with an area of 25 ctA in series. That is, since the total area is sufficient to be 500 mm, it is sufficient that it occupies only a portion of the surface of the automobile body.

ことも可能である。If you use a more efficient solar cell or increase the area of the solar cell, it is possible to charge the storage battery 3 only with the solar cell 4 without using a generator, as shown in Figure #g2. It is possible.

る。As described above, the electric device for a car according to the present invention charges the on-board storage battery using the solar battery attached to the car body, and the self-discharge of the storage battery can be compensated for by the output of the solar battery due to solar radiation. This system automatically prevents so-called "power overload," which occurs when the vehicle becomes unable to start due to a decrease in the residual capacity of the battery, which not only brings great convenience to the user, but also allows the omission of an alternating current generator. This will bring about a major change in the system.
