E-bike charger is not a very eye-catching accessories, generally how not charging problems, few people will notice it, but if if it is really out of order, it is quite troublesome, because without it charging, your e-bike can not run for a long time ah, but if it really out of order, do not worry too much, Eahunt here can provide you with some solutions.
1、The power indicator light is on while charging, and the charging indicator light is orange.
First of all, please check whether the charger output plug of the e-bike and the charging plug of the battery box are tightly plugged. If you are sure that there is no problem, you can check whether the fuse above the battery box has an open circuit or the fuse holder is loose with poor contact.
2、Power indicator does not light up, the charging indicator does not light up.
Check whether the charger input power plug is connected, the charger input plug into a normal power outlet, if the situation remains the same, open the charger shell, observe whether the fuse connection is intact, there is no circuit breakers, such as no circuit breakers, first check whether the power input line is good, after ruling out the failure of the power input line, you should check the board near the high-voltage area of the components whether the phenomenon of false welding. After eliminating the power input line, you should check whether there is any false soldering of the components near the high voltage area on the board. In addition, the open circuit will also cause the above failure, such as the machine fuse has been broken, then never replace the large ampere fuse, should focus on checking its components are not damaged, available with the same type of replacement.
3、Serious heating, and even shell burned deformation image
This is mainly part of the user often carry with the car caused by some components loose caused by the failure. Mainly manifested as: voltage working condition is not normal, the heat is very large, serious charger shell deformation, circuit board burnt, resulting in voltage damage. Can be re-welded to the virtual welding place. If you still can not rule out the problem, you need to check whether there are components open circuit.
4, the output voltage is normal, but the charging current is very small
When encountering this situation, you should check whether the voltage components have poor contact or damage, if everything is normal, then replace the charger to eliminate the problem!
5、Heat generation is large, and accompanied by abnormal sound, charging into the electricity
The cause of the failure is caused by the output stage damping capacitor damage. In addition, the components of the open circuit or false welding can also cause the above failure.
6、Abnormal sound when working, the power indicator and charging indicator light is dark and blinking.
The cause of the failure is component damage, you can replace the damaged components, and make the charger output voltage within the normal operating range.
Eahunt Technology produces professional electric car charger, ultrasonic welding, with full shut-off function, multiple specifications, complete certification, welcome to consult.
