Many electric scooters often stop and cannot drive normally when they go. The main reason is that they are walking on the road. The vehicle will not go after a pier, but it will go after a tap, or turn off the key and start it again, and then continue to walk. The second type is that the key is turned on and there is power to indicate that there is electricity. Turn the speed handle. This is just a few bites and a slight movement. The reason for this is basically the same as the previous failure. It is caused by poor power contact. . The specific reasons for these two situations can be analyzed from the following aspects.
The main power connection and the battery connection are disconnected
The main power source line of the electric scooter includes the battery connection line, the battery output line, and the main power supply line of the vehicle body. As long as there is a poor contact in these appearances, the power supply of the whole vehicle will not be normal. Sometimes the voltage is insufficient and the vehicle cannot start normally. Sometimes the electricity meter shows full range when it is turned on. All of these are measured and checked according to specific steps.
Solution: Use a multimeter to measure the total power supply of the electric scooter. If the output is abnormal, we must open the seat package to check the battery connection line and the output of the battery. Find the fault point where the contact is poor, reconnect, measure again, and ride the bike normally, the problem can be solved.
Lock connection line
The poor contact of some vehicles will occur at the fixed point of the lock and the line connection. All need to be checked step by step with a multimeter, first check from the air switch, whether there is a virtual connection of the line, the contact is not connected, and the lock connection plug is found all the way, all must be checked. You can find it with the buzzer file of the multimeter, and you have to pull it with your hands to see if there is a virtual connection.
As long as the problem is found, the solution is very simple, just reconnect it. If the fixed point of the lock is burned out, it is necessary to replace the lock with a new one, so that all the problems are solved.
Sometimes the road is uneven, and after using for a long time, the connection wires of the motor and the controller are easy to burn and have poor contact. As long as one of the wires is in poor contact, the vehicle will not be able to walk normally or gnaw. These problems are also very simple to deal with. Open the seat package and first check whether the motor Hall is normal and whether the connecting wire is loose or burned out. If these fault points occur, reconnect and debug normally to solve the problem. If the problem is not resolved, check whether the controller service output is normal.
The electric scooters have poor circuit contact, damaged locks, and the motor and controller fault points are a bit obvious to find, and some are more secretive. As long as you are patient and check slowly step by step, you can find the problem.
It is relatively simple to solve. It is normal to reconnect the short-circuited connection point. If it is a major problem, you need to repair the motor, controller and lock. If it can't be repaired, you need to replace it with new accessories.
