2.3.6 Equalization Charging (EQ charging)
It is strongly recommended to read this section carefully before you start the EQ
charging and Don’t leave battery unattended while performing desulfuration.
Always check if your battery supplier recommended EQ charging. Only start when
it is suitable.
If battery type was set at AGM, GEL or Lead-Carbon , this charging can’t be
triggered on.
Over a period of time, the cells in a traction battery can develop uneven chemical states. This will
result in a weak cell which in turn can reduce the overall capacity of battery. To improve the life and
performance of these non sealed battery, SP include a manual equalization program that can be
used, if recommended by battery manufacturer.
Through this page, you can initiate the desulfuration program manually. After entering this page,
please press “ENTER” button to trigger on the EQ charging. Detailed operation, please refer to
chapter 7.5 ‘’Para_Battery’’.
After 30 minutes, it will quit EQ and enter into float charge.
Check electrolyte level and refill battery with distilled water if necessary.
If you want to come to normal charging, you need stop equalization charging and switch off the
unit.
Switch on the unit again, then you will have your equipment back to normal charging.
During equalization, the battery generates potentially flammable gases. Follow all
the battery safety precautions listed in this guide. Ventilate the area around the
battery thoroughly and ensure that there are no sources of flame or sparks in the
vicinity
Turn off or disconnect all loads on the battery during equalization. The voltage
applied to the battery during equalization may be above the safe levels for some
loads.
Frequency:
Maximum once a month, for heavily used battery, you may wish to equalize your
battery. For battery with light service only need to be equalized every 2-3 months.
Important:
1) Equalization can damage your batteries if it is not performed properly. Always check
battery fluid before and after equalization. Fill batteries only with distilled water.
2) Always check the equalization switch is set back to OFF after each time’s equalization.
3) Battery manufactures’ recommendations on equalization vary. Always follow the battery
manufacturer’s instructions so batteries are properly equalized. As a guide, a heavily used
battery may require equalization once a month while a battery in light duty service, only
needs equalizing once every 2 to 4 months.
Battery type:
As a protection, equalization charging can be performed if and Only if you set the
battery to be traction, Flooded /OPzS batteries. If you choose AGM, GEL or Lead-
