There are a number of reasons. First of all, check whether there is an ammeter on the charging machine to see whether it is overcurrent, whether the charging machine and the battery pack are compatible, the battery surface should be cleaned, and the charging machine will trip out of phase.
maintenance methods
1. The power indicator is off, and the charging indicator is off.
Maintenance method: Check whether the input power plug of the electric forklift charger is connected to the mains.
2, electric forklift charger heat is large and accompanied by abnormal sound.
Maintenance method: The cause of the fault is the damage of the output stage vibration absorption resistance R31 and C17. In addition, C12 open circuit or virtual welding can also cause the above faults.
3, electric forklift charger work abnormal sound, can not charge the battery.
Repair method: Check the C8 on the circuit board for welding or damage. Generally, replacing C8 can solve this problem.
Forklift is powered by batteries, there is nothing similar to the air switch can trip, but the forklift has insurance, insurance can be fused; If the power supply of the charging part of the forklift is tripping, you can consider current overload, AC voltage is too low, the switch itself is faulty, and the line has leakage current
