Electric bicycles have been used for a long time, and they often encounter problems of one kind or another. When we encounter these problems, how should we solve them? I think everyone is not very clear. Here is a detailed introduction to the common problems of electric bicycle charging:

Problem 1: The green light will be on when the battery is charged for one hour (the battery will be full as soon as it is charged, and it will run out as soon as it is used).

　　1 The charger voltage is low and the battery is seriously undercharged: replace or repair;
　　2 The battery has entered a period of decline and cannot meet long-term discharge: replace or repair.

Problem 2: After charging for 8 hours, the green light of the charger is off, and the battery is hot.

　　1 The charging voltage of the charger is too high: replace or repair;
　　2 The battery pack or a single battery in it is faulty: replace or repair.

Problem 3: The battery leaks.

　　1 Damaged battery: replace or repair the battery;
　　2 When charging, the battery position is reversed, and the charging voltage is high.

Problem 4: The battery is sufficient, but two red lights are under load (the under-voltage light and over-current protection light are on, and the motor is turned off.)

　　1 The output voltage of the charger is low: replace or repair the charger;
　　2 Short battery charging time: recharge to extend the charging time;
　　3 The capacity of the battery pack or one of them has decreased: replace the battery;
　　4 Electrode damage or poor contact: replace or repair the electrode.

Problem 5: The battery is full and the indicator lights are all on, but the load hub is weak.

　　1 Gear wear and slip: replace or repair the gear;
　　2 Partial short circuit of the hub motor winding: replace or repair the motor;
　　3 Electric bicycle assembly problem or component wear: readjust the tightness of the electric bicycle component nut;
　　4 The motor shaft gear damping rubber of the electric bicycle is damaged: replace or repair.
