200000.00 Dollar US$ Electric Vehicle Manufacturers Share Charger Charging Issues Abita Springs

Below, Electric Vehicle Manufacturers shares the troubleshooting of battery car chargers that cannot be charged or charged:

1. Check the charger and the circuit: plug the charger into the charging hole without connecting to 220V power supply. See if the charger indicator shows. There is no display, this depends on whether the connection between the battery terminal and the charging hole is broken, and the contact is not good. No problem with the connection is the charger problem. There is a display, and then connect 220V AC power to see if the charging display is normal charging. No normal charging is a problem with the charger itself. If it shows that it can charge normally, it is a problem with the battery.

2. Battery pack detection: After removing the battery pack, the capacity of a single battery will be tested to see the actual capacity of each battery in the battery pack. Too. Connect all parts of the circuit firmly, and the charger must be replaced if it is abnormal. The dried cells in the battery compartment should be supplemented with pure water for pulse repair. The voltage of the three batteries in the group should be controlled at 13.4V / only. If the voltage difference between the batteries exceeds 0.3V, sulfidation will continue to occur during use because they are not synchronized. Therefore, special attention should be paid to the problem of battery configuration after repair (especially users of electric motorcycle batteries) that need to be replaced. They must be replaced.

3. If the battery is leaking and cannot be charged:

First do a visual inspection to find the location of acid leakage. Remove the cover sheet to see if there are traces of acid leakage around the cap valve, and then open the cap valve to observe whether there is flowing electrolyte inside the battery. After the completion of the above work, if no abnormality is found, the air tightness test should be done (inflate and pressurize in water, observe whether the battery generates bubbles and emerges, and bubbles indicate acid leakage). Finally, during the charging process, observe whether there is a flowing electrolyte, and if so, explain the reason for production. During the charging process, if there is flowing electrolyte, it should be exhausted.

If the battery is not charged, first check whether the charger is damaged and whether the charging parameters meet the requirements: that is, the initial charging current reaches 1.6-2.5A / only; the maximum charging voltage reaches 14.8-14.9V / only, and the charging floating charge conversion current reaches 0.3- 0.4A / piece, the float charge voltage reaches 14.0-14.4V / piece.
