During the use of electric tricycles, some problems such as abnormal noise from the motor are inevitable. So what is to be done with these problems? In fact, some small problems you can still solve by yourself. Today I will tell you some maintenance tips.
1. The motor has abnormal noise
If there is abnormal noise from the engine, there are three main reasons. The first is that the Hall element burned out, resulting in a phase loss. For such problems, you can choose to replace the Hall. The second is the physical failure of the engine, which can be fixed as long as the fault is verified. The third is that the bearing is oxidized, it is enough to apply lubricating oil.
2. The brake is not turned off
There are two main reasons for brake power failure, the first is that the brake power switch is damaged or poor contact, for such problems, if the contact is bad, it can be repaired, and if it is damaged, it is better to choose to replace it. The second is that the controller has burned out, you can only choose to replace the controller with a new one, please remember to fix it well when you replace the controller, it is best to use "anti-skid" screws to tighten the anti-skid to avoid bad conditions of the road and bumps causing the original controller to be empty Welding short circuit and damage!
3. The charger does not charge
There are five main reasons, first, the charger or battery fuse is blown, please replace the fuse. Second, the battery pack wiring is disconnected, just plug it in. Third, if the charging plug of the battery pack is broken, please replace it with a new one. Fourth, if the battery is damaged, you can choose to repair it or replace it with a new one.
4. The battery is full as soon as it is charged and it is finished as soon as it is used
The main reason is the failure of the battery vulcanization. The vulcanized battery can be repaired with a repair tool. Fuzzy digital control theory is adopted. By measuring the state of the battery, positive and negative frequency conversion particle waves are continuously emitted during charging and discharging. It takes 10 to 20 hours to remove the hard lead sulphate that crystallizes in the battery.
