Description

GRAND intelligent microprocessor чарджерс are designed for charging and starting all types of lead-acid batteries (WET / MF / CA / EFB / GEL / AGM). The charging function is 10 steps fully automatic.

the work cycle (start-up / cooling) in the start-up function is automatic, which protects the device against overheating and damage. The rectifiers enable the selection of the battery type, the selection of the battery operation mode (charging / start-up / regeneration) and the Generator test function. У них есть защита против искр, обратной полярности, короткого замыкания, переохлаждения и переохлаждения.

STAGE 1: DIAGNOSTICS: analysis of the battery, its state of charge and correctness of connections between the battery and the charger.

STEP 2: DESULFATE: recognition of a sulphated battery, low voltage, high тока импульсный charging.

STAGE 3: SOFT START: if the battery is not повреждены, charging with a relatively low current (about 15%) begins, gradually increasing its value.

STEP 4: MAIN CHARGING: charging with the maximum current of constant intensity with a value automatically adjusted depending on the state of charge of the battery, until reaching 80% of the battery capacity.

STAGE 5: ANALYSIS: checking if the battery accepts the charging current - prevents charging и поврежденных battery.

STEP 6: CONSTANT CHARGE: charge with constant voltage and compensate for false full charge reading resulting from high current charging of the battery.

STEP 7: RECOVERY: charge with more charge and compensate for the side effect of the reduced charge current.

STAGE 8: ADSORBATION: charging with small current pulses of constant intensity until the maximum Battery voltage is reached.

STEP 9: TEST: checking if the battery is storing voltage.

STEP 10: MAINTENANCE: monitoring the battery voltage and maintaining the optimal charge at 95-100% capacity through charging current pulses, in case a decrease in the given value is detected.
