SECTION 5 | Battery Charging in Evolution™ Series
For 3-Stage Adaptive Charging Prole Option "0=3 Stage Adaptive" (See Srl. No. 1 in Table 5.2), T1 Timer (explained
under Bulk Stage in Section 5.7.1.1 and Fig 5.1) computes the time of charging in this stage as follows:
• Absorption Time "T1" = Bulk Charge Time "To" x 10 ("To" = Time from entering Bulk Charge Stage till battery
voltage rises to 0.3V below Absorption Voltage).
• The “T1 Timer” has minimum time of 1 hour and a maximum time of 12 hours.
• When the "T1 Timer" runs out, the charger will enter the next Float Stage.
• Programming range and Default values of Absorption Voltage are shown in Table 6.2.
For the other 3-Stage Charging Proles, "Stage 2 - Absorption Stage" is controlled as follows:
• Option "1 = 3 Stage Type 1" (See Srl. 2 of Table 5.2)
• Option "2 = 3 Stage Type 2" (See Srl. 3 of Table 5.2)
This stage is displayed as "X-Absorption Stage" in the 2
nd
line of the Charging Mode screens in the Remote
Control EVO-RC-PLUS. [Refer to the screen Nos. 1 to 5 shown in Fig 3.3(a) under Section 3.6.4.1 of EVO-RC-PLUS
Remote Control Manual. Character "x" denotes code for the Charging Prole that is active. For details of codes for the
Charging Proles, please see Table 3.2 under Section 3.6.4.3 of Owner's Manual for EVO-RC-PLUS]
5.7.3 STAGE 3 – Float Stage
Float Stage is a maintenance stage in which the Duty Cycle of the boosted high frequency PWM voltage pulses (Section 5.1.2)
is adjusted continuously to keep the battery voltage at level = the programmed parameter "FLOAT VOLTAGE", typically about
13.5V for 12V models and 27.0V for 24V models to maintain the battery’s charge without losing electrolyte through gassing
and also, prevent corrosion of Positive plate by maintaining proper Positive Plate Polarization Voltage. Programmable range of
values of "FLOAT VOLTAGE" are shown in Table 6.2. Default value is 13.5V for EVO-1212F / EVO-1212F-HW and 27.0V for
EVO-1224F / EVO-1224F-HW. For programming of parameter "FLOAT VOLTAGE", refer to Section 4.4.2.4 of EVO-RC-PLUS
Remote Control Manual.
This stage is displayed as "X-FLOAT STAGE" in the 2
nd
line of the Charging Mode screens in the Remote
Control EVO-RC-PLUS [Refer to the screen Nos. 1 to 5 shown in Fig 3.3(a) under Section 3.6.4.1 of EVO-RC-PLUS
Remote Control Manual. Character "x" denotes code for the Charging Prole that is active. For details of codes for the
Charging Proles, please see Table 3.2 under Section 3.6.4.3 of Owner's Manual for EVO-RC-PLUS]
5.7.4 Automatic Resetting of Charging Cycle
The charging cycle will be reset to the Bulk Stage [Section 5.8.2.1] as follows:
a) If the AC input is disconnected and is reconnected
b) If battery discharges and its voltage falls to the voltage level set by programming parameter "RESET TO
BULK" [For details, refer to Section 4.4.2.15 of EVO-RC-PLUS Remote Control Manual]. Programming range
for this parameter is:
i. 10 to 13VDC for EVO-1212F / EVO-1212F-HW (Default value is 12.0VDC)
ii. 20 to 26VDC for EVO-1224F / EVO-1224F-HW (Default value is 24.0VDC)
c) If the charger remains in the Float Stage for 10 days
