The switching operation of the control transistors is performed by a control signal from an output port of the controller 100, and the width of the conductive pattern of the FETs (conductive Angle). That is, when the amount of charging current is smaller than a predetermined value (approximately 5 A), the width of the conduction pattern is increased, and when the amount is larger, the width of the conduction pattern is decreased.

Here, when the FET is used, the amount of current to be handled is large in the case of battery charging. Therefore, in a normal transistor control, the heating value of the charging channel unit CN _{1 to} CN ₅ per channel is several tens of watts. (Eg about 6

The charging channels CN _{1 to} CN ₅ are selected by 〜 520 ₃ and their voltage signals are input to the A / D converter 110 side of the controller 100 via the output line 530.

Since the charging voltage monitoring section 500 can detect the charging voltage on each of the charging channel sections CN _{1 to} CN ₅ , the connection state and the charging state of the connected battery 30 to be charged are set at the time of charging setting. Can be detected.

That is, when the battery 30 to be charged is connected, a voltage signal corresponding to the voltage at the time of connection is input to the A / D converter 110 of the controller 100 through the output line 530. Then, a digital signal from the A / D converter 110 corresponding to this input value is processed in the controller 100, and if this value is in the range of 7 to 17V, connection of a chargeable battery (suitable battery) And the charging progress lamps LE _ep , LE _hw , LE

In response outside the battery V battery is connected, turn on the connected transistors TR ₁ to the output port of the controller 100, play continuously alarm buzzer BU.

When the corresponding charge start switches SW _{1 to} SW ₅ are operated within the range of 7 to 17 V, the charge voltage is input to the controller 100 via the A / D converter 110. Is compared with an internal set voltage value (for example, 13.9 V), and the value is, for example, 12.1 V
If it is less than V, the controller 100 blinks the battery empty lamp LE _ep (E: red) of the charging progress lamp,
In the case of 12.1 to 13.9 V, the charging lamp LE
_hw (→: yellow) blinks, and when it exceeds 13.9 V, the full charge lamp LE _fu (F: green) is turned on. The set voltage value = 13.9 V can be changed as appropriate by operating the setting section (digital switch) 260 of the controller 100.

The input voltage monitoring section 600 has a built-in voltage dividing resistor between the + and-terminals 210 and 220 from the charger 20.
To the A / D converter 110 side. Then, the corresponding digital signal from the A / D converter 110 is converted into a set value (normal input voltage value = 14 to 2) in the controller 100.
(0 V, abnormal input voltage value = less than 14 V or more than 20 V), and when the input voltage value is normal, the transistor TR ₂ connected to the output port of the controller 100 is turned on, and the normal lamp LE _no is turned on.

On the other hand, when less than 14V, the on the transistor TR ₂ - turns off, normal lamp LE _no
With blink, the transistor TR ₁ connected to the output port of the controller 100 on - turns off intermittently sounding the alarm buzzer BU. In addition, 20V
When ultra is the transistor TR ₂ On - turns off, the blink normal lamp LE _no, turns on the transistor TR ₁ connected to the output port of the controller 100, play continuously alarm buzzer BU.

Next, a method of using the battery charger adapter for a vehicle according to the present invention will be described. Various operations of the charging adapter are performed by a predetermined program stored in a memory in the controller 100.

First, the pair of charging cables 21 and 21 on the charger 20 side are connected to the + and-terminals 2 on the adapter body 10 side.
10, 220. At this time, if the connection is normal, the alarm buzzer BU does not sound and the normal lamp LE _no is turned on. On the other hand, when the charging cables 21 and 21 are reversely connected, the alarm buzzer BU sounds continuously, and at the same time, the abnormal lamp LE _ab is turned on. Therefore, the operator can immediately know the normal connection or the reverse connection.

When the charging cables 21 and 21 are normally connected, the input voltage value from the charger 20 is detected by the input voltage monitoring unit 600, and the value is determined as the normal input voltage value =
If it is within the range of 14 to 20 V, the normal lamp LE _no is turned on. Thereby, the worker can know the state in which charging can be started.

On the other hand, when the input voltage value is less than 14 V (insufficient voltage), the normal lamp LE _no flashes and the alarm buzzer BU sounds intermittently. This allows the operator to know that the input voltage is insufficient.

Further, when the input voltage value exceeds 20 V, the normal lamp LE _no flashes and the alarm buzzer BU sounds continuously. Thereby, the operator can know that the input voltage is excessive.

When the input voltage is insufficient or the input voltage is excessive, the operator may appropriately operate an adjustment knob or the like of an output voltage adjusting unit on the charger 20 side. With these operations, when the input voltage value falls within the range of the normal input voltage value = 14 to 20 V, the normal lamp LE _no is turned on. This allows the operator to know that the input voltage value is within the normal input voltage value.

After the normal setting with the charger 20 has been completed as described above, the charging cable 1 from the charging channels CN _{1 to} CN _{5 of the} adapter body 10 is next transferred.
3 _{1-13 5} is used to connect to the desired target charging battery 30. The connection to the charging channel units CN ₁ to CN ₅ can be made at random, and up to five units can be connected. Of course, each of the channel portions CN _{1 to} CN ₅ is driven independently.

When this connection setting is performed normally,

But if the rechargeable outside of the battery of 6V or 24V battery, the voltage signal from the charge voltage monitoring unit 500 is input to the controller 100, the transistor TR ₁ connected to the output port is turned on, the warning buzzer BU Sounds continuously. At this time, the charging progress lamps LE _ep , LE _hw , and LE _fu are not turned on or off by the controller 100 and remain off. by this,
The operator can know that the connected battery is not compatible with charging.

And the corresponding start lamp LE₁~ LE_FiveAnd charging

You can know the condition.

If the electrode portion of the battery 30 to be charged is defective, the charging is started normally, and the rate of increase of the charging voltage is calculated by the controller 100. That is,
The charging voltage is input to the controller 100 through the charging voltage monitoring unit 500, and a predetermined charging voltage value (for example, 12 V)
When the voltage rises by 1 V after a certain period of time (for example, 30 seconds), the controller 100 determines that the rising speed is too fast, so that the alarm buzzer BU sounds a plurality of times (for example, five times) and at the same time, the corresponding charging channel all lamp parts CN ₁ -CN ₅ is lit, to stop charging. Thereby, the worker can know the electrode failure.

On the other hand, when the charging is completed due to the progress of the charging by the normal connection, the alarm buzzer BU sounds for a predetermined time (for example, 2 minutes) by the controller 100, and at the same time, the start lamps LE _{1 to} LE ₅ and the charging progress lamps. LE _ep , LE _hw , LE _fu full charge lamp LE _fu (F:
(Green) lights up. Thereby, the operator can instantly and visually know the completion of charging.

Since it takes a long time (usually about 5 hours) to complete the charging, even if no worker is present after the completion of the charging, if the battery is still connected, the drop in the battery voltage is monitored by the charging voltage monitoring. Monitoring is performed by the unit 500, and when there is a certain voltage drop (for example, 0.5 V), the controller 100 starts recharging. This recharging, for example three times, is thereafter it remains fully charged state, waiting for the charging cable _{131-134 5} is removed. However, at the time of the first recharging, the alarm buzzer BU is sounded for a fixed time (for example, two minutes). Thus, the worker is not restricted by the removal time of the battery 30 to be charged, and can be charged when the hand becomes empty or at night.

[0046] After the charging is completed, it can remove the charging cable _{131-134 5} from the charging battery 30.

As described above, such a charge driving is performed by

In addition, in the adapter body 10 of the above embodiment, the number of charging channels is five in order to accommodate five batteries 30 to be charged at one time. However, the present invention is not limited to this, and the number of charging channels is two to four. Alternatively, it is of course possible to set the number to six or more.
