行つた後、充電を終了する。(Prior Art) Progress is being made in the development and practical use of automated guided vehicles that run unmanned on factory floors without relying on rails. Such an automatic guided vehicle travels by driving a traveling motor using a DC power source from a battery mounted on the vehicle body. This type of automatic guided vehicle has different running time, running frequency, conveyed weight, etc., and thus has different battery power consumption. Therefore, when a predetermined period of time has elapsed since the start of the transport work, the transport work is stopped and the battery is charged. Apart from this, there is a system in which each automated guided vehicle is equipped with an integrating wattmeter to integrate the power consumption and charge the vehicle according to the amount of power consumed. -Known from No. 153536. In addition, a charging device for an automobile battery is disclosed in Japanese Patent Application Laid-Open No. 132738/1983.
This charging device has a voltage detection circuit that outputs an output when the terminal voltage of the battery reaches a predetermined potential, and measures the time from the start of charging the battery by turning on the power switch circuit until the voltage detection circuit detects the predetermined potential. It is configured to include a clock circuit and a control circuit that turns off the power switch circuit after a time corresponding to the time measured by the clock circuit has elapsed. Therefore, this charging device charges the battery, and when the terminal voltage reaches a predetermined potential, the battery is further charged for a time corresponding to the time it takes to reach the predetermined potential, and then charging is terminated.

In the former charging method, a running battery mounted on such an automatic guided vehicle is charged with charging characteristics as shown in FIG. However, as described above, after a predetermined period of time has elapsed after carrying out the transport work, the remaining capacity of the battery of each automatic guided vehicle differs. Therefore, the remaining capacity of the battery is, for example,
The remaining capacity is 80%, assuming that it will be 80% or less.
If the charging time T 1 (approximately 4 hours) is uniformly set and charged after the battery has reached , batteries with remaining capacity in the range of 80 to 100% (Figure 5 ~) will be overcharged and the battery life will be shortened. This also requires a large amount of rehydration of the electrolyte.

There is a problem in shortening the . Further, it is conceivable to use a constant voltage constant current charging method as a charger, but such a charger is extremely expensive and has problems such as a significant increase in equipment cost. Alternatively, according to the latter charging method, there are problems such as the charging control circuit becoming complicated due to the provision of an integrating wattmeter. Furthermore, according to the car battery charging device disclosed in Japanese Patent Application Laid-Open No. 57-132738, charging is performed if the terminal voltage of the battery is below a predetermined value at the start of charging; In some cases, there is a problem that charging is not performed and the battery is over or under charged.

In the figure, a three-phase AC power source 1 is connected to AC input terminals 3u, 3v, and 3w of a charger 3 via a normally open contact 2a of an electromagnetic switch 2.
The DC output terminals 3x, 3y of the charger 3 are connected to feeders 4, 4 arranged in parallel with an appropriate distance apart. A voltage detection unit 5 consisting of a voltage relay that detects a state in which the voltage of the battery to be charged is, for example, 2.4 V/cell, that is, the remaining capacity of the battery is approximately 80% of the battery capacity, is connected to the DC output terminals 3x and 3y. The output signal is input to the charging control section 6. Further, a signal from a normally open contact 7a which becomes a closed circuit when a current collector to be described later comes into contact with the feeder 4, 4 is input to the charging control section 6.

間T2を計時する。 The charging control section 6 is composed of a microcomputer or the like, and includes a timer 61, a calculation section 62, and a timer 63. The timer 61 indicates that the remaining capacity of the battery to be charged is a predetermined value (for example, 80% of the battery capacity).
%) to complete charging, T 1 = f(T 2 )...( 1 ) However, f(T 2 ): determined by the calculation unit 62 as a function of T 2 Calculated. The charging time T 1 is calculated by, for example, T 1 =A×T 2 +B (2) where A, B are constants. Further, when the charging time T1 set in the timer 61 has elapsed, the charging control section 6 opens the normally open contact 2a of the electromagnetic switch 2, and ends the charging operation. When the remaining capacity of the battery to be charged is less than a predetermined value (for example, 80%) at the start of charging, the timer 63 measures the charging time T2 from the start of charging until the remaining capacity recovers to the predetermined value.

とする。 By the way, the constant B in equation (1) above is the charging time up to ~ in Figure 2, but even if the remaining capacity of the battery to be charged is above a predetermined value, it may be too short or too short. Since the remaining capacity is not constant, charging is started near the point and the time is given as a guideline to avoid damaging the electrodes. In other words, an example of how to determine constant B as a guide is: B = (4 hours) ÷ (constant 1 to 3 based on empirical rule)

とする。 Further, the constant A is determined so that the charging time T1 is 4 hours when charging is started from the remaining capacity of the battery at 0%. This value changes depending on the combination of the charger and battery, but it is determined by the charging time from when the remaining capacity of the battery starts charging from 0% until it reaches a predetermined value. For example, A = (4) Time - B) ÷ (charging time T 2 from remaining capacity 0%) ...(4).

The current collectors 10, 10 provided in the battery charger are brought into contact with the power feeders 4, 4 of the battery charging device to become ready for charging. The contact between the feeders 4, 4 and the collectors 10, 10 is confirmed by the closing of the normally open contact 7a (1),
The remaining capacity of the battery 8 is detected by the voltage detection section 5, and it is determined whether it is above or below a predetermined value (2). The remaining capacity of battery 8 is below the specified value (see Figure 2)
If it is (2), the normally open contact 2a of the electromagnetic switch 2
is closed (3), and at the same time as charging starts, the timer 63 starts counting the charging time T2 (4). When the capacity of the battery 8 reaches a predetermined value (see FIG. 2) by the charger (5), the calculation unit 62 calculates the charging time T 1 based on the measured time T 2 using the above equation (2).

る。 Note that the timer 63 stops its timekeeping operation and returns to 0 when the remaining capacity of the battery 8 reaches a predetermined value. Charging is performed for the charging time T1 set in the timer 61, and when the charger time T1 has elapsed,
(7), the normally open contact 2a of the electromagnetic switch 2 opens, and the charging operation ends (8). This charging time T1 increases the remaining capacity of the battery 8 from 80% to 100%.

バツテリ８の残存容量が所定値以下である状態で
充電を行つても充電の過、不足は生じない。 In this way, when the remaining capacity of the battery 8 is lower than a predetermined value, first increase the remaining capacity to the predetermined value, and then calculate the charging time T 1 until charging is completed based on the charging time required for charging. from,
Even if charging is performed when the remaining capacity of the battery 8 is below a predetermined value, overcharging or undercharging will not occur.

値を超えてからの充電時間T1のみで充電を終了

つても充電不足は生じない。 On the other hand, if the remaining capacity of the battery 8 is above the predetermined value (2), the normally open contact 2a of the electromagnetic switch 2 is closed, and the charging time T 1 of the timer 61 is set as T 1 = f(T 2 ).
Charging is performed as follows. In this case, T 1 is T 1 = A×T 2 +
B, if the remaining capacity of battery 8 is greater than the predetermined value shown in Figure 2, the charging time is
Since T 2 is not timed, T 1 = B, and charging is performed for the preset time B, and the charging time is
After T 1 has elapsed, the normally open contact 7a is opened (8) to terminate charging. In this way, when the remaining capacity of the battery 8 is above the predetermined value (80 to 100%), charging is completed only in the charging time T 1 after exceeding the predetermined value, so that the remaining capacity of the battery is greater than the predetermined value. Even if it is, there will be no shortage of charging.
なお、第２図に示した充電特性とは異なり第４

使用すればよい。 Note that, unlike the charging characteristics shown in Figure 2, the
As shown in the figure, if the remaining capacity of the battery is less than a predetermined value and its charging characteristics do not have linearity, the formula T 1 = f (T 2 ) that sets the charging time T 1 can be calculated as an n-dimensional equation. Calculate in section 62,
A plurality of constants may be determined by sampling the time T2 until the point in FIG. 4 is reached an appropriate number of times.
For example, the number of samplings n may be determined as n=(number of curved portions)+1, and the remaining capacity of the battery may be 0% and the charging times T 2a , T 2b , and T 2c from each waveform curving point may be used.
なお、本実施例では無人搬送車のバツテリの充

Further, in the embodiment, the predetermined value of the remaining capacity of the battery is 80%, but it goes without saying that this is just an example.

As detailed above, when charging a battery, the present invention determines whether the remaining capacity of the battery at the time of starting charging is above or below a predetermined value, and if the remaining capacity is below a predetermined value, the battery is charged. The charging time until reaching a predetermined value is measured, and based on the time measurement result, the charging time is calculated from the time when the predetermined value is exceeded to the end of charging, and charging is performed. Furthermore, if the remaining capacity is equal to or greater than a predetermined value at the start of charging, charging is performed for a preset time.

In addition, since the charger does not use a constant voltage/current method, it is inexpensive, and since no integrating wattmeter is used, there is no risk of an increase in equipment costs, and other excellent effects are achieved. The present invention is suitable for charging batteries in cases where power consumption varies greatly among batteries, such as batteries used in automatic guided vehicles.
