Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lead-acid battery activator capable of reducing the amount of lead sulfate precipitated on an electrode plate of a storage battery, and more particularly to a lead-acid battery activator which is easily connected to a storage battery (battery) of a vehicle such as a forklift. And a lead-acid battery activator with a connector.

[0002]

2. Description of the Related Art In general, in a lead-acid battery, a sulfuric acid precipitate generated during use adheres to a sponge electrode plate and a lead oxide electrode plate, crystallizes and inhibits the flow of ions, and lowers the power generation efficiency of the storage battery. Has the property of letting you do.

In order to remove the sulfuric acid precipitate, there has been proposed a lead-acid battery activator which removes lead sulfate adhering to the surface of an electrode plate by applying a voltage pulse having a fast rise to the electrode of the battery.

The lead-acid battery activator includes, for example, a capacitor connected to both sides of a DC voltage source, a transformer having a primary coil and a secondary coil connected to both sides of the capacitor, and intermittently connecting and disconnecting the capacitor. A switching circuit that includes a transistor that generates a current pulse that is greater than the discharge leakage current value of the storage battery and has a fast rise in the secondary coil and gives the current pulse to the lead oxide storage battery, and controls the current supplied from the DC voltage source. By discharging the capacitor, a current pulse larger than the discharge leakage current value of the storage battery and having a fast rise is applied to the electrode plate to peel off the lead sulfate attached to the surface of the electrode plate.

To connect the lead storage battery activator to the lead storage battery, a power supply cable is screwed to each of the negative electrodes of the storage battery, and a charging voltage source side connector is connected to the other end of the power supply cable. This is performed by fitting.

[0006]

When the lead-acid battery activator according to the prior art is mounted on a vehicle such as a forklift to which a large number of storage batteries are connected, for example, 24 heavy objects built into the seat or body of the forklift or the like are used. The storage battery has to be taken out of the vehicle once, and the electrodes must be attached to the positive and negative electrodes of the storage battery with screws.

This problem will be specifically described with reference to FIG. For example, a forklift 600 that transports luggage while an operator is standing is a device that operates the operating lever 604 while the operator is standing on the deck 601 to drive the fork 603 up and down and the like. The storage batteries 602 are driven by a number of storage batteries 602 housed below the storage batteries 604. As shown in FIG. 4, the storage batteries 602 are vertically arranged in 4 × 6 rows, and a positive electrode 702 of each storage battery 602 and a negative electrode 700 of another storage battery. Are connected in series by a conductor, and the electric circuit of the vehicle is connected to the positive electrode (reference numeral 800) and the negative electrode (reference numeral 801) of the storage battery at the ends. Note that reference numeral 701 denotes a water supply port.

In this forklift 600, it is necessary to reduce the size of the vehicle in order to reduce the turning range of the vehicle.
For this reason, the large number of storage batteries 602 are stored compactly below the operation lever 604. On the other hand, in a seat-type forklift, a large number of storage batteries are generally stored under a seat. Since these storage batteries require a large amount of electric power, for example, 24 lead capacitors of 2 V are connected in series.

When a lead storage battery activator, which is the object of the present invention, is attached to the storage battery of these forklifts, a large number (24) of storage batteries, which are heavy objects, are pulled out from the side of the vehicle body shown in FIG. The lead-acid battery activator is connected by screwing and soldering.However, as mentioned above, the storage space for the battery is limited due to the small size of the car body. There was a problem that it could not be stored. Further, even in a seated forklift, the lead-acid battery activator has to be mounted on a large number of storage batteries, and there is a problem that the space for accommodating the lead-acid battery activator is small.

As described above, in the forklift according to the prior art, no consideration has been given to mounting the lead storage battery activator due to downsizing, and the work of pulling out a heavy storage battery is required, so that the mounting work is complicated. There was a problem that there was. Particularly, in an environment where a large number of forklifts are used in a factory or the like, it is very complicated to attach the lead storage battery activator to a plurality of forklifts.

In addition, the lead-acid battery activator is attached to the storage battery according to the prior art because the terminal is soldered and corroded by corrosive gas leaking from the storage battery. To prevent this corrosion, grease is periodically applied to the terminal portion. There was also a problem that maintenance such as painting was required.

It is an object of the present invention to eliminate the disadvantages of the prior art and to provide a lead-acid battery activator that can be easily mounted on a lead-acid battery.

[0013]

In order to achieve the above object, the present invention relates to a lead-acid battery activator having a built-in circuit for removing lead sulfate attached to the surface of a battery plate by applying a current pulse to the plate of the battery. A terminal for fitting to the connector terminal of the connection cable of the storage battery and a terminal for fitting to the connector terminal of the power cable on the charging side are integrally fixed to the circuit of the lead storage battery activator.

Further, the present invention is characterized in that the lead storage battery activator is provided with a pulse filter for preventing the current pulse from being output to a connector terminal of a power cable on the charging side.
