Common faults and troubleshooting of chargers adapter
Charger failure one
There is a display on the meter head, the charging lamp is not bright, the lamp is not bright or dim when connected, and it cannot be charged
Cause Analysis:
1. Although the charger is connected to the battery, there is a disconnection in the middle. 2. The battery is aging and the voltage is too low. 3. The battery pack does not match the charger (the battery pack voltage is lower than the charger's rated voltage)
Method of exclusion
1. Check the connecting bolts and connecting wires. 2. Check the total voltage of the battery and the voltage of a single cell. If the battery is open, aging, or the voltage is too low, replace it.
Charger failure 2
The meter head has a display, the light is on and it cannot be charged, and the charger stops immediately after it is turned on
Cause Analysis:
1. Poor contact of AC power supply. 2. The battery pack does not match the charger (the battery pack voltage is higher than the charger's rated voltage)
Method of exclusion:
1. Check whether the input power supply is connected to the wrong socket or the socket, if the connection is not good, replace it. 2. Check whether the battery pack voltage is consistent with the charger.
Charger failure three
The charging current is unstable and cannot reach the maximum rated current
Cause Analysis:
1. The power supply voltage is too low 2. The cross-sectional area of the power input line is too small 3. The neutral line is too thin
Method of exclusion:
1. The power supply voltage must not be less than 195Vac. If it is too low, replace the power supply. 2. The cross-sectional area of the power input line should be greater than or equal to the cross-sectional area specified in the manual.
Charger failure four
The charging current is unstable, sometimes large and sometimes small
Cause Analysis:
1. Poor contact of the output connector generates heat and becomes loose. 2. The battery cable is loose or the battery connector is corroded.
Method of exclusion:
1. Check the copper conductor of the connector, and replace it if there is overheating, oxidation, burrs, or looseness. 2. Tighten the battery cable and clean the battery connector.
