5.5.1.3 Battery charge current limitation (default setting 75%)
For maximum battery life, a charge current of 10% to 20% of the capacity in Ah
should be applied.
Example: optimal charge current of a 24V/500Ah battery bank: 50A to 100A.
The temperature sensor supplied automatically adjusts the charging voltage to the
battery temperature.
If faster charging – and a subsequent higher current – is required:
- The temperature sensor supplied should always be fitted, since fast charging can
lead to a considerable temperature rise of the battery bank. The charging voltage will
be adapted to the higher temperature (i.e. lowered) by means of the temperature
sensor.
- The bulk charge time will sometimes be so short that a fixed absorption time would
be more satisfactory ('fixed' absorption time, see ds5, step 2).
Procedure
The battery charge current can be set in four steps, using DIP switches ds4 and ds3
(default setting: 75%).
