Ia 7.1.6.
This profile type has been included as a maintenance tool to be used at a
workshop level for carrying out maintenance charge on damaged batteries
and is not a charge profile intended for regular charging of traction
batteries.
Stage 1 Current
Percentage of the nominal charger
current (set in the configuration) that
is used for the bulk charge stage,
normally set to 100%.
Stage 1 Timeout
Maximum time the charger will stay in
bulk charge. If this time is exceeded
the charger stops with a major alarm
as it could indicate a faulty battery
with short circuit cells. Whilst the
setting is in minutes the timeout is
actually calculated based on amp hours
returned to the battery rather than just
time, allowing a faulty charger module
to reduce the charge current available
and lengthen the bulk charge time
according. Although a faulty power
module should always be replaced, in
most situations the charger will still
complete a charge cycle with one
module failed.
Stage 2 Voltage
When the charger output voltage (per
cell) reaches this level, the charge is
terminated and the green light is
illuminated.
