CHARGING STAGES AND FEATURED TECHNOLOGY

ULTIPOWER CHARGER ARE COMPLETELY DIFFERENT FROM CONVENTIONAL

CHARGERS YOU MAY FIND IN MARKET. THE REVERSE PULSE TECHNOLOGY HELPS

REDUCING BATTERY INTERNAL IMPEDANCE WHILE CHAGING. THE BATTERY GASSING

AMOUNT IS ALSO ONLY 10%-13% OF THAT ON BATTERY CHARGED BY NORMAL

BATTERY. TEMPERATURE RAISE OF BATTTERY WHILE CHARGING IS ALSO GREATLY

LOWERED.

ULTIPOWER CHARGER APPLIES ADVANCED CHARGE ALGORITHM. THE REVERSE PUSLE

WILL MAINTAIN AND EQUALISE BATTERY CELLS DURING THE ENTIRE CHARGE

PROCESS. UNLIKE NORMAL CHARGER, WHICH EQUALISE CELLS,IF THE FUNCTION

EXISTS, ONLY BY INCREASING CHARGE VOLTAGE AFTER FLOATING PHASE.

ULTIPOWER REVERSE PULSE CHARGER WILL LIFT THE CELL VOLTAGE WHICH ARE

LOWER THAN AVERAGE AND LOWER THE ONES HIGHER. THUS AVOIDING HIGHER

VOLTAGE WHICH BRING HAZARD OF OVER-CHARGE AND GASSING.

CURVE BASED ON 12V1.5A AUTOMATIC CHARGER

THE BASIC CHARGE STAGES :

Starting phase for charging. The starting phase continues until the battery’s terminal

voltage has risen over a preset level. At this point, charging goes into the bulk phase.

If the terminal voltage has not reached the preset level within a preset time,

charging is suspended. The error mode is indicated. If a large battery is charged

that has been severely discharged, it may be necessary to restart the charger after

a preset time.

Primary charging where approximately 80% of the charging takes place. The

charger delivers maximum current until the terminal voltage has risen to the preset

level. UltiPower charger will monitor the battery voltage. Bulk current will be

transferred to enable efficient charge if the battery voltage is under the gassing

voltage.

Voltage is kept at the preset level. During this phase, the current is gradually

reduced. Gassing voltage may be exceeded in this phase. UltiPower charger will

increase the amplitude and frequency of reverse pulse to ensure the minimal

gassing amount.

Charging is suspended for a short period and the battery voltage is measured. If it

falls rapidly, the battery is probably faulty. Charging is suspended and an error is

indicated.

Voltage has dropped to preset level with controlled current.

State of charge varies between 95% and 100%.The pulse charge is safety

replenishing the last 5% of the battery’s charge in a minimum amount of time.

The battery receives a pulse when the voltage sinks, keeping the battery in good

shape when it is not being used. If the battery is charged and/or the battery’s

terminal voltage drops, the charger starts a charge pulse until the voltage has

reached the preset level. The charge pulse is then interrupted and the cycle is

repeated as long as the charger is in pulse maintenance phase. If the terminal

voltage drops even lower, the charger automatically reverts to the beginning of the

charging curve.

Note:The charging data can be adjusted as per customers’ needs.
