d) The charging process of the "RLG 7008"

Charging an accumulator takes place with the Reflex charging station "RLG 7008" in four stages:

Soft start

1. Soft start with continuous broadening of the charging impulses
In the soft start phase, the connected accumulator is formed in that the charging current is
increased slowly up to the final value set. During the soft start, the discharge current impulses are
switched off.
2. Quick charging with maximum charge impulse breadth and final charge recognition
The quick charge process concerns the actual Reflex charge. Evaluation of the increase speed
of the charging voltage takes place within it.
At a certain point of the charging curve (see figure 4 further back in these operating instructions),
the charging control recognises the so-called "reverse point": quick charging is then terminated.
The accumulator has now already taken up more than 90% of the storable energy.
If the accumulator is required urgently, it can be defined and used already at this point in the
charging process.
3. Transitional charging
Two-hour impulse charging takes place here with 10 % of the maximum charging current. The
accumulator is thus brought up to 100 % of the storable energy.
4. Floating charging
After termination of the transitional charging, the charging control in the "RLG 7008" is switched
to so-called floating charging which is carried out with C/40 current impulses.
The charging losses arising through self-discharging of NiCd and NiMH accumulators are thereby
compensated constantly. In this operating condition, the accumulator may remain connected for
an indeterminate period of time. You should disconnect the accumulator, however, and switch off
the charging station (charging devices may not be operated without supervision!).
