池が使用されている。In order to obtain good high rate discharge characteristics, it is necessary to increase the surface area of the electrode plate, and laminating many thin electrode plates is effective. It is well known that it is effective to fill the lattice with a large amount of active material. However, the same storage battery is used for automobile storage batteries even though they are required to have different characteristics as described above.

明する。On the other hand, due to the recent trend toward low maintenance of storage batteries, this trend has also appeared in automobile storage batteries, and many batteries with low liquid loss, that is, low self-discharge, use lead-calcium umbrellas for the lattice. It's coming. However, in storage batteries that use a fluid electrolyte and a lead-calcium alloy lattice, the lattice corrodes due to repeated low-rate discharges.
It had a shorter lifespan than conventional storage batteries with a lead-antimony alloy lattice. On the other hand, storage batteries with thick grids made of calcium alloy and fine glass mats used as separators to make the electrolyte non-fluid improve both low-rate discharge characteristics and time-minute characteristics. ◇The present invention was made in response to the different characteristics required of automotive storage batteries as described above and the tendency for less maintenance. This is an automotive storage battery system that includes a second storage battery as a power source for driving a load, and will be described in detail below using examples.

信頼性をも向上させることができる。In FIG. 1, the jlH storage battery 5 is a storage battery with good high rate discharge characteristics, and the second storage battery 5 is a storage battery with good low rate discharge characteristics. These two types of storage batteries are charged in parallel through the regulator 2 when the generator 1 is activated when the car is running, but since two storage batteries are charged at the same time, there is a possibility that the battery will be insufficiently charged more than before. are doing. In order to prevent such problems from occurring, the present invention is configured to connect a parallel circuit of a diode 7 and a resistor 8 in series with the second storage battery 5, so that the first storage battery 5 is charged preferentially. . That is, at the beginning of charging, when the difference between the voltage of the first storage battery 5 and the voltage of the second storage battery 3 is higher than the forward voltage of the diode 7, the second storage battery 3 is charged via the diode 7, and the voltage is low. The current is charged through the resistor 8. On the other hand, the first storage battery 5 is charged directly from the generator 1 via the regulator 2.
The charging current of the storage battery 5 is greater than the charging current of the second storage battery 3, and the first storage battery 5 is charged preferentially, and at the same time, at the end of charging, the voltage of the first storage battery 5 and the The voltage of the second storage battery 6 can be balanced by the resistor 8.Also, even if a large current flows to the starter 6 when the engine starts and the voltage of the first storage battery 5 drops, the second storage battery 3 tries to discharge. , since the discharge current is limited by the resistor 8, the second storage battery 3 is not affected by the first storage battery 5.Furthermore, the second storage battery 5 is mainly discharged when the car is running. Therefore, since the charging current is flowing through the first storage battery 5, the charging current is flowing through the first storage battery 5.
However, no discharge current flows through the load 4. For this reason, a storage battery with good high rate discharge characteristics is used as the first storage battery 5 as a power source for starting the engine, and a storage battery with good low rate discharge characteristics is used as the second storage battery 3 for other loads such as lighting. If used as a drive power source for a storage battery, the reliability of the storage battery itself can be improved, and the reliability of car electronics equipment, which is susceptible to drops in storage battery voltage, can also be improved.

値は大なるものである。As described above, the present invention not only improves the reliability of the storage battery itself and the power source for car electronics equipment, but also makes it possible to reduce the size and weight of the storage battery as a power source for starting an engine, and also to make it possible to reduce the size and weight of the storage battery as a power source for starting an engine. The storage battery as a power source for driving the load can be installed outside the engine room. This makes it possible to more effectively configure the electrical system of an automobile by taking into account the effects of voltage fluctuations, etc., and has great industrial value.
