Attention!
S'assurer que les paramètres de charge comme l'absorption, flotter et tensions de péréquation et compensation de la
température de la charge externe contrôleur sont set / programmé pour correspondre aux paramètres par défaut / pro-

5.5 bAttery teMPerAture SenSor
A battery Temperature Sensor Model EVO-bCTS has been provided [fig 2.5(a)]. It comes with
5 m / 16.5 ft cable. Connect the ring terminal end (houses the sensor) on the battery Positive
or Negative post [fig 2.5(b)]. Connect the rJ-45 plug to the Temperature Sensor Jack (6, fig.
2.1). The Temperature Sensor is used to ensure optimum charging by modifying the charging
voltages based on temperature if the battery sees very wide temperature swings. In addition to
compensating AbSOrPTION, EQUALIZATION AND fLOAT VOLTAGES, the thresholds of "LOW
VOLT ALArM", "bATT LOW VOLTAGE" shut down, "rESET VOLTAGE" and "bATTErY OVEr
VOLT" are also temperature compensated. Temperature compensation will be carried out over
a temperature range of –20°C to + 60°C. Table 6.2 shows the programmable range. Default
settings for the temperature coefficient is -4mV/°C/Cell.
5.6 3 StAge ChArging MoDe: buLk, AbSorPtion & FLoAt For
norMAL ChArging
Normal day to day charging is performed in a 3 Stage, Normal "CHArGE MODE"—bULK,
AbSOrPTION and fLOAT— to provide rapid and complete charge cycles without undue battery
gassing. Please see Table 6.2 for details of programmable settings and Default Values. This 3
Stage Charging is the Default "CHArGE MODE" (refer to parameter "CHArGE MODE" at
Screen No. 12 of Table 4.4 of Owner's Manual for EVO-rC at Apendix A).
fig. 5.1 shows the voltage and current charging curves with respect to time and different
charging stages.
NOTE: With the optional Remote Control Model EVO-RC (see Owner's Manual at Appendix A), it is
possible to program and activate 4 Stage Charging Mode including the 4th Equalization Stage. 4-Stage
charging is required to be carried out only on flooded / wet cell batteries. This 4 Stage Charging Mode
is discussed separately under "4 Stage Charging Mode in Equalization Mode" at Section 5.7.
5.6.1 bulk Charge Stage
In the first stage, known as the "bULK" Charge Stage, the charger delivers the maximum
"bULK CUrrENT" ("Io") that has been programmed through the "Parameter Setting Menu"
of the optional remote Control Model EVO-rC. range and Default value are shown at Table
6.2. This current is delivered to the batteries until the battery voltage approaches its Gassing
Voltage i.e. Absorption Voltage (programmed as "AbSOrP VOLTAGE"—typically around 14.4
volts for 12 volt batteries and 28.8 volts for 24 volt batteries (again, this voltage can vary based
upon the desired values programmed through the "Parameter Setting Menu" of the optional
remote Control Model EVO-rC (see Appendix A). The bulk Charge Stage restores about 75%
of the battery's charge. The Gassing Voltage is the voltage at which the electrolyte in the battery
begins to break down into Hydrogen and Oxygen gases. Under normal circumstances, a battery
should not be charged at a voltage above its Gassing Voltage (except in the manually selected
Equalization Stage) since this will cause the battery to lose electrolyte and dry out over time.
