Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a battery with a charge / discharge status display function that allows the state of a charging or discharging system to be visually identified in the actual operating condition of the battery.

[0002]

2. Description of the Related Art Batteries incorporating display means have already been developed. For example, using a microcomputer to measure the charging current and discharging current and displaying them digitally or using a photodiode are the mainstream. Although various other developments have been made, the charging current and discharging current of a single battery can be checked. At present, it was not structured.

The above-described charge current and discharge current display device using a microcomputer detects a voltage between battery terminals, associates the detection result with the voltage between terminals, and responds to a decrease in the voltage value based on the voltage between terminals. Since the charge current and the discharge current are measured and displayed by a digital display or a photodiode, the circuit configuration of the display means needs to be complicated, so that the cost is high.

[0004]

SUMMARY OF THE INVENTION In view of the foregoing, the present invention allows the state of charge current and discharge current to be accurately grasped visually by processing the existing battery body top cover 1, and the conventional technique 2. 3 can be solved, the conventional battery can be used as it is, the charge current and the discharge current of a single battery can be checked, and the battery can be provided at a low cost. It is intended to provide a battery with a charge / discharge status display function.

[0005]

As described in section 2.3 of the prior art section, a system using a microcomputer which is currently mainstream uses a mechanical display for displaying a charge current and a discharge current. There were problems such as becoming expensive.

Therefore, in order to achieve the above object, the battery with a charge / discharge status display function of the present invention utilizes the characteristics of current and magnetism and can use the inside of a conventional battery case or an existing battery as it is. In addition, it is possible to check the charge current and discharge current of a single battery, provide a battery with a charge / discharge status display function that is inexpensive and does not require a complicated circuit configuration. By doing so, the above problem is solved.

[0007] In addition, a normal battery is provided with a positive terminal 21a and a negative terminal 21b. When a current flows from the charging device from the positive terminal toward the inside of the battery, the battery is charged. Conversely, when a current is released from the + terminal to various loads mounted on a vehicle or the like, on which a battery is mounted, a discharge state occurs, and a magnetic field due to the current is generated inside and around the battery case of the battery. In the charge state and the discharge state,
Since the magnetic field is also reversed in the same direction as the current flow, by installing the compass magnet 3 in the magnetic field, the direction in which the compass needle swings due to the attraction action or repulsion action changes the charging state. The problem is solved by utilizing and applying the principle because the principle is reversed in the discharge state.

[0008]

According to the present invention, a commercially available compass 3 and a magnet piece 8 are used for fixing or embedding in the battery body upper lid 1 without using an electronic type requiring a complicated circuit configuration. The disadvantage described in the prior art 2.3 is easily solved, and the charging current and the discharging current of the battery alone can be confirmed.

Further, a magnet piece 8 is provided on the inner side wall of the compass magnet 3 so as to attract an arbitrarily determined one-side pole of the compass needle 7, and a straight line connecting the positive pole 21a and the negative pole 21b of the battery 1 is formed. In addition, since the compass 3 is fixed or embedded so that the center of the compass 3 and the magnet piece 8 are located, a complicated circuit configuration is not required, so that a manufacturing process and a battery manufacturing stage or later Since the work process such as mounting is also easy, the cost can be reduced.
