---|---|---|
Charger failure
|
Check whether the charger is working properly. There may be something wrong with the charger that prevents it from charging properly.
|
Check whether the charger is working properly. You can try to use another charger for charging test.
|
Battery damage
|
The battery may be damaged or aged and cannot be charged properly. You need to replace it with a new one.
|
If the battery is damaged, you need to replace it with a new one.
|
Charging port failure
|
Check if the charging port of the electric scooter is damaged or loose. It may be that the port is faulty and cannot be charged.
|
Check whether the charging port is damaged or loose. If there is any problem, repair it or replace it with a new one.
|
Charging circuit failure
|
Check whether the charging line is connected properly. Charging may be impossible due to a line fault.
|
Check whether the charging circuit is connected normally. If there is any problem, repair the circuit or replace it with a new one.
|
Power outlet failure
|
Test the wall outlet that the battery charger is plugged into for a fault.
|
If you determine that there is no power at the wall outlet, its circuit breaker may have tripped or the wall outlet may be faulty and need to be replaced.
|
If the above methods cannot solve the problem, it is recommended to contact the electric scooter’s after-sales service center or professional maintenance personnel for inspection and repair.

原因分析
Unable to charge to 100%
Faulty battery charger, damaged or loose or corroded wire terminal connections, faulty charger port, or other problems with the charging system
Over-discharge
The battery or battery pack has been over-discharged and the voltage level has reached an over-discharge level that is detected by the battery charger and therefore it will not be charged. This can happen when the electric scooter is not in use, the power switch or key switch is in the on position, or when the cell or battery pack is stored without being fully charged, or when the cell or battery pack has not been charged for a long period of time.
解決
Confirm charging record
Determine how long the battery pack has been uncharged. If it has been uncharged for less than 6 months, you may be able to successfully charge the battery pack.
If it has been uncharged for more than 6 months, the battery pack will usually self-discharge to a voltage level where it cannot be recharged and needs to be replaced.
また, if the power switch is on for more than a few days, the battery pack will discharge to a voltage level where it cannot be recharged and needs to be replaced.
If the power switch has been on for more than a few days, or the battery pack has been sitting for a long time without being charged, the battery pack may be over-discharged and may need to be replaced.
Try charging the battery pack for 8 時間
If the battery pack charges in less than 8 時間, try charging the battery pack to 100% for 8 hours or more.
Test the battery charger port
If the battery charger is plugged into the wall, unplug it. Plug the battery charger into the battery charger port on the electric scooter and see if the charger’s indicator light comes on. If the indicator light on the battery charger comes on, then the wiring and wiring connectors to the charger port are good, and the charger port itself is good. Not all battery chargers have an indicator light that comes on when the charger is just plugged into the vehicle, so if the light does not come on, you should do a secondary voltage test with a multimeter as described below.
If you have a multimeter, you can test the voltage at the battery charger port. The voltage level at the charging port should be the same as the voltage level of the battery pack. If the charger port has male terminals, you need to be very careful to avoid shorts between the terminals or in the charger port casing (if it is metal).
Test the battery charger
Make sure there is voltage at the charger port, then test the voltage of the battery or battery pack to confirm it needs charging.
Plug the battery charger into the charger port, plug into the wall, and use a digital multimeter to test the voltage of the battery pack.
If the voltage rises slowly, the charger is charging the battery. Continue charging until the indicator shows a full charge, then test the battery voltage to confirm it has reached 100% charge.
If the charger cannot charge to 100%, there may be a problem.
