SOFTWARE MANUAL C32
22 APPENDIX A: BATTERY CHARGER
22.1 SOFTWARE BASED CONTROL IN GENERAL
If the controller is used with NiHM batteries a charging connection backed by the processor is available. The performance
of this charging connection and its survey is controlled by an appropriate configuration via system parameter. See list of
printer parameters: Charge (44)
22.1.1 STARTING THE CHARGING PROCESS WITH FORMAT CHARGING
The battery charging device consists of a harware component and the corresponding charging control software in the
μ-processor. On application of the charging voltage the hardware first controls the battery charge condition. If the battery
is exhaustively discharged the charging cycle starts with a formatting charge to protect the battery (the load indicator is
off). As soon as the battery voltage for fast charging is reached the controller takes control and activates fast charging.
22.1.2 DISPLAYING AND REQUESTING CHARGING STATUS
Different blinking intervals of the status LED indicate the charging status. When a status request command is made the
serial interface issues corresponding confirmations. See: Error and status messages in printing operation.
22.2 CHARGING MANAGEMENT
A current limitation of the charging circuit does not exist in some GeBE controllers.
In the controllers this charging management is done by the processor. Some special controller variations have a charging
current regulator "on board" which allows charging from a fixed voltage (power supply 8V - 28V) or from a car battery (12V
or 24V).
Some GeBE controllers (Low cost mostly) have a NiMH charging circuit
without
own charging current limitation. The
limitation is made with the proper GeBE battery charger.
ATTENTION:
Use the proper GeBE battery charger only or contact us if you need one!!
To recharge NiMH batteries never use a fixed voltage power supply without a defined charging current limitation.
22.2.1 ENDING CRITERIA OF NiMH BATTERY RAPID CHARGING
As soon as one of the following conditions is fulfilled rapid charging is ended and switched to trickle charging:
•
End of charging by timer
•
Minus Delta V identification
•
Maximum V identification
•
Delta T identification
•
Maximum T identification
