1.Introduction
An electric forklift battery to store electricity required for an electric forklift driven battery by changing commercial power source from AC into DC has not a few of cases of considerable reduction of battery caused by overcharge and undercharge according to excessive operation in ordinary times, irregular quantity of discharge and incomplete charging
This product is micom-controlled automatic charger, that has supplemented such weak points and has used semi-constant voltage/constant current charging type by a leakage transformer with rationally high efficiency
2. Property
Multi-functions of this product have been automated by an 8-bit micom mounted digital system.
2-1 Conditions of full charge
(1) Micom completes the charging by detecting an output voltage and deciding the amount of charge that is automatically corresponded to the amount of discharge (About 8 hours of charging, in case of 80% charging)
(2) Automatic extended charging of total 2 hours, in case of an ambient temperature less than 5°C
(3) Automatic extended charging of 2 hours in case of equalizing charge.
(4) AC pressure cutout in case that output power of the battery is cut out.
(5) Temporary suspension of charging in case of phase losses in an input side such as blackout and automatic return to charging in case of restoration of power supply
(6) Completion of charging when the battery terminal voltage gradually increases in case of low input alternating current voltage and total charging time exceeds 15 hours
(7) Completion of charging when the battery terminal voltage increases in case of high input alternating current voltage and the voltage reaches overcharge
(8) Stoppage of charging when an emergency stop switch is pushed
2-2. Equalizing charge function
Possible to perform equalizing charging by pushing an equalizing charging button in order to equalize the weight of each cell
2-3. Auxiliary charge function in winter time
Micom solves the insufficiency of operation time due to decrease of solution temperature of the battery in a cold district by detecting an external temperature.(Extended charging of 2 hours in case of an ambient temperature less than 5°C)
2-4. Emergency stop switch
(1) The charging is temporarily stopped when an emergency stop switch is pushed, and all LED lamps give notice of emergency stop while switching on and off simultaneously
(2) All LED lamps are put out when the emergency stop switch is pushed again in the above status.
(3) In case of cancellation of the emergency situation and resumption of the charging in the above status, it returns to the charging when the emergency stop switch is pushed again.
