8.7.6 NiCd battery settings
NOTICE!
– A two stage charging procedure with an upper charge voltage U1 and a lower charge
voltage U2 is used for charging NiCd batteries.
–
The parameter settings allow the upper charge voltage U1 to be adjusted according to the
actual prior discharge depth or according to an assumed fixed discharge depth. The
discharge current of the NiCd battery must be measured using one or more external PA
HS400 current sensors in order to determine the actual depth of discharge. The PA HS400
sensors used for measuring the discharge current must be registered via the
‘Battery control mode è Sensor member list’ dialogue.
– Temperature compensation of the upper charge voltage U1 can also be programmed.
Separate temperature compensation factors can be set for temperature ranges above 0 °C
and below 0 °C.
– Adjustment of the upper charge voltage U1 depending on the discharge depth and the
temperature compensation is performed up to a configurable limit for U1.
– Charging with the upper charge voltage U1 specified in the configuration is performed for
the configurable charging time U1.
– The configured charging time U1 starts counting down when the voltage of the NiCd
battery has reached the active charge voltage U1, under consideration of a configurable
tolerance threshold, and can be maintained at this value using the available charge
current.
– The charging time U1 is reset when the battery drops below a configurable discharge
depth. Charging of the NiCd battery is then restarted using the active upper charge
voltage U1.
– Charging of the NiCd battery switches to the lower charge voltage U2 after the charging
time U1.
– Separate lower charge voltage U2 temperature compensation factors can also be set for
temperature ranges above 0 °C and below 0 °C.
– In contrast to the upper charge voltage U1, the lower charge voltage U2 is not adjusted
based on the discharge depth.
– Charging at the lower charge voltage U2 continues until the battery is discharged below
the configurable U2 U1 switch voltage threshold. Charging of the NiCd battery is restarted
using the active upper charge voltage U1 when the battery drops below this threshold.
