Equalize
Equalize charging is the only charge mode that the
RE-4500 does not enter automatically. During Float
charging, the user turns on Equalize charging with the
RE-ICC remote. Equalize charging is another constant
current charging mode with a time out. The system
again directs the constant DC Absorption current (10
A
DC
for 24V
DC
, -
5 A
DC
for 48V
DC
) into the battery
while monitoring the Absorption voltage limit of 31
V
DC
(
62 V
DC
). Once the limit is encountered or 15
minutes has passed, the system either continues or
begins Float charging.
Battery Temperature Sensor
A user-installed option is an external, battery temperature
sensor. It provides for battery overheat detection (default 120
°
F), and battery voltage temperature compensation during
charging. The following section describes how the “Battery
Temperature Compensation for Charging” feature works.
•
The default setting is 3.6 mV
DC
/
°
C. The factory setting
for this option is “OFF.” It may be turned “On” with the
RE-ICC remote.
•
The compensation value only affects the charging voltages
when the battery temperature is above 77
°
F. This is a
safety feature to avoid applying excessive battery voltage
when battery temperatures are low.
•
The compensation value affects each of the battery Float,
Bulk, Absorption and Equalization values, and charging
modes. For example if the Float battery setting is 26.0 V
DC
,
and the battery temperature is 107
°
F, and the battery
temperature coefficient is -10 mV /
°
F then the float value
used by the software will be 26.0 V
DC
- {10 mV /
°
F
×
(107
°
F - 77
°
F)
×
12 cells} = 22.4 V
DC.
•
The default setting for “High Battery Temperature”
shutdown is 140
°
F (60
°
C). This setting is the upper limit of
battery temperature compensation.
