5.8 4 STAGE ADAPTIVE CHARGING PROFILE - EQUALIZATION
!
CAUTION!
4-Stage Adaptive Charging Profile - Equalization should be used only for vented, flooded (
non-sealed or
“wet”
) batteries and not on sealed AGM / Gel Cell / Nickel-Zinc (
Ni-Zn
) / Lithium batteries and only as often as
recommended by the battery manufacturer.
!
ATTENTION!
Profil de charge adaptative en 4 étapes - L'égalisation ne doit être utilisée que sur des batteries ventilées (non
scellées ou «humides») et non sur des batteries scellées AGM / Gel / Nickel-Zinc (Ni-Zn) /Lithium et seulement
aussi souvent que recommandé par le fabricant de batteries.
5.8.1 Brief Description:
4-Stage Adaptive Charging Profile for Equalization is used to equalize Flooded / Wet Cell Lead Acid Batteries.
Equalization is carried out periodically – normally once per month for battery under heavy duty service and every 2 to
4 months for battery under light duty service. During the Equalization Stage, the battery is intentionally over-charged
/ boiled for a specified time period to equalize voltage of individual cells. Other benefits include reduction in sulfation
and stirring up of the electrolyte to remove stratification. This results in maintaining the peak capacity of the battery.

INFO
Please read Section 1.4.4 regarding more details on
necessity of equalizing batteries
.
This 4-Stage Adaptive Charging Profile can be activated as follows:
• Using optional Remote Control Model EVO-RC-PLUS. Programming Parameter “EQUALIZE-4STAGES” is required
to be set at “1=Yes”.
Refer to Section 4.4.2.12 of EVO-RC-PLUS Manual.
• If Remote Control EVO-RC-PLUS is not available, by pressing On/Off Push Button on the front panel of the EVO
TM
(11, Fig 2.1) for 1 sec. The cycle can be stopped prematurely by pressing the On/Off Push Button for 1 sec. Please
refer to Section 5.9 for more details.
5.8.2 4-Stage Adaptive Charging Profile for Equalization – Charging Curves
Fig 5.2 shows the voltage and current curves during the 4 stages under this profile. Details are explained below:
As part of this
Adaptive Equalization Algorithm
, the charging process in the Equalization Stage is based on time
"To"
which is the time the charger remains in the initial Constant Current Bulk Charging Stage. In the Bulk Charging Stage,
charging takes place at constant current (
referred to as "CC" at programmed value of parameter "BULK CURRENT"
)
[See
Section 4.4.2.1 of EVO-RC-PLUS Remote Control Manual]
. The charger will remain in the initial Bulk Charging Stage for a
longer duration when the battery is deeply discharged and for a shorter duration if the battery has a shallow discharge.
