VOLTAGE parameter (Figure 3-5) represents the real-time voltage value of the connected battery.
The parameter is not user-changeable
– value is detected automatically once the test cables are
connected to the test object.
The following parameters need to be set before charging is started:
•
Charge U.
Maximum charge voltage. Maximum value to be set is 300 V DC.
•
Charge I.
Value of the constant charging current. The maximum current value depends on a
selected charging voltage, but it does not exceed 25 A.
The BAC25A sets automatically the value of
Charge U
and
Charge I
parameters depending on the
battery voltage being measured. The
Charge I
current
is set as maximum respecting the battery
voltage level. If the device is / remains connected to the battery charged in the previous test, the
same value of
Charge U
parameter as in the previous test will be set. However, if the BAC is
connected to a battery string of different nominal voltage comparing to the previous charging,
