Charge Profiles
There are six choices for charge profiles. These profiles have default time and level settings that are detailed below. The profile’s settings can also be
modified various ways in
Service Parameters
for custom applications to satisfy a customer’s needs.
IEI (Flooded)
IEI is the standard flooded profile. The first stage of the charge cycle
(the first I in IEI) is current mode at start rate current which is defaulted
to 16% of the amp-hour rating. Start rate current is maintained as the
battery voltage increases until gassing voltage is reached. Gassing
voltage is set normally at the default rating of 2.37 volts/cell. Once
gassing voltage is reached, the charger goes into the E mode where
the charger voltage is held constant at gassing while the charge
current tapers off. Once the charge current reaches the finish rate of
4.5% of the amp-hour rating (default), the charger enters the final I
mode of the charge cycle. Charge termination will occur once the
battery voltage flattens out in finish I mode (dvdt) or if the time period
after the gassing voltage is reached is 5 hours (time-voltage),
whichever comes first. This result occurs if the charge termination is
the default
“Both dvdt or time-voltage”
setting.
Defaults:
Start Rate Current
16% of Battery AH
Gassing Voltage
2.37 V/C
Termination Method
Both dvdt or Time Voltage
Time after gassing limit
5 Hours
Finish Rate
4.5% of Battery AH
Charge Time Limit
14 Hours
IEIE (Sealed)
IEIE profile is more commonly referred to as sealed or VRLA. This
profile is similar to IEI except that the finish rate constant current is 2%
of the amp-hour rating of the battery. Also, there is an added voltage
mode (E) in the profile that will hold the battery voltage to 2.53volts/cell
(default) until the charge cycle finishes. Dvdt termination does not
apply in the sealed profile. Charge termination will occur when the
time-after gassing reaches 4 hours if the battery voltage
does not
reach 2.53 volts/cell. If the battery voltage reaches 2.53 volts/cell
before the 4 hour time limit, an added 2 hours in constant voltage E
mode is added to the charge cycle.
Defaults:
Start Rate Current
16% of Battery AH
Gassing Voltage
2.37 V/C
Termination Method
Time Voltage
Time after gassing limit
4 Hours if under 2.53 V/C
2 Hours if 2.53 V/C reached
Finish Rate
2% of Battery AH
Charge Time Limit
14 Hours
AGV (Auto Guided Vehicle)
Automatic guided vehicle. AGV is an IE profile with a two hour time-
after-gassing time limit. Charge cycle will terminate if the time-after
gassing limit is reached
or
if the charge current drops below finish rate.
If battery is disconnected from charger during the charge cycle, no
‘Open Battery’
fault will result.
Defaults:
Start Rate Current
16% of Battery AH
Gassing Voltage
2.37 V/C
Termination Method
Time Voltage or Charge Current
falls below Finish Rate
Time after gassing limit
2 Hours
Finish Rate
4.5% of Battery AH
Charge Time Limit
14 Hours
I (VVR)
Constant current mode throughout entire charge cycle. Charge current
is limited to finish rate (default).Charge time limit defaults to 32 hours.
Defaults:
Start Rate Current
4.5% of Battery AH
Gassing Voltage
Does not apply
Termination Method
Does not apply
Time after gassing limit
Does not apply
Finish Rate
Does not apply
Charge Time Limit
32 Hours
IE (Floating)
Also known as floating mode. Constant start rate current until gassing
voltage then constant voltage (E) mode. Gassing voltage default is
2.35 volts/cell. While in constant voltage mode, display indicates
‘floating charge’. Note that there is no charge time limit in this profile.
Charge cycle will continue indefinitely while battery is connected.
Charge current may fall to zero with no
Open Battery
fault while
charger is in floating (E) mode. Disconnecting the battery while in float
mode will not result in a fault. However, disconnecting the battery while
charging in start rate (I mode) or in equalize will cause an
Open
Battery
fault. In case of a hot battery, charge current is limited to finish
rate in floating mode. If charge current rises above finish rate, charge
cycle will terminate as
Charge Complete.
Defaults:
Start Rate Current
16% of Battery AH
Gassing Voltage
2.35 V/C
Termination Method
Floating indefinitely
Time after gassing limit
Indefinite
Finish Rate
Floating (Does not apply)
Charge Time Limit
Indefinite
Opportunity
IE profile with a default of 10 hours time-after-gassing, settable up to
32 hours. Overall charge time limit default is 32 hours. When charge
cycle is in constant voltage (E) mode, the charger is ‘floating’ and
disconnecting the battery will not result in an
Open Battery
fault.
Defaults:
Start Rate Current
16% of Battery AH
Gassing Voltage
2.37 V/C
Termination Method
Time Voltage
Time after gassing limit
10 Hours
Finish Rate
Floating (Does not apply)
Charge Time Limit
32 Hours
