How To Fix Electric Scooters – 9 Easy Things To Check
Electric scooters are really interesting and good for the environment. A sad fact in life is that if you ride an electric scooter long enough, you need to fix something. Fortunately, repairing electric scooters is not difficult. If the electric scooter stops working, the article will tell you how to fix electric scooters.
9 things to check when repairing an electric scooter
1-Reset your scooter
Many electric scooters have a reset button or reset program. If you are not sure how to reset the scooter, please check the manual. If you don’t have one, please check the manual or guide of the electric scooter online.
2-Check termination or arm switch
Many electric scooters have an end switch or arm switch. This allows the scooter to be energized, but the motor will not run unless the switch is in the correct position. If the display on your scooter works but does not move, please check this. If you are not sure about the location of the electric scooter, please check the manual or find the manual online.
3-Check the fuse or circuit breaker
Most electric scooters have fuses or circuit breakers. This is to prevent damage to motors, batteries and electronic equipment. If you run the scooter at full speed with the motor stopped, it may be damaged by overcurrent. A fuse or circuit breaker can prevent this from happening. If your scooter stops or gets stuck, you may have blown the fuse. If your scooter gets wet or rains, it may short-circuit the circuit and it may blow the fuse. Your scooter may have multiple fuses or circuit breakers, so please check the manual.
To check the fuse, place it under the lamp and see if there is a burnt connection inside. You can also use a multimeter to check the conductivity of the fuse. Once the fuse is blown, it will be an open circuit.
4-Make sure the battery is fully charged
Make sure the battery of your electric scooter is fully charged. If the battery is dead, your scooter will not run. There may be enough power to power electronic devices and displays, but not enough to move the scooter.
If it has been months since you last rode the scooter, you should fully charge the battery before attempting to ride the bike.
Check the indicator lights on the battery charger and battery to verify that the charger is working properly. Different chargers use different light modes. Check your scooter manual to see what your scooter battery charger should show.
5-Check the motor
Check the motor. There are many different motor types and positions on electric scooters. Some have built-in hub motors in the front or rear wheels. Some rear wheels have belt or chain transmission. Some high-power scooters have motors on the front and rear wheels.
Check the motor for any debris that might get stuck in it and stop it from running.
Check the connectors on the motor to make sure they are firmly inserted. Check the wiring for wear or abrasion that may cause a short circuit.
Smell the motor. It shouldn’t smell like burning. The burning smell indicates that the motor is overheated and the circuit is burned out.
Some electric scooters use brushed motors. Brushes are small metal parts that push the shaft to transfer current to the motor. The brush will wear out over time. The surface rubbed by the brush may burn or deposit carbon. A burnt surface or carbon deposits will prevent the flow of electricity. If the current does not flow, your motor will not rotate.
If the motor is brushless, it has no brushes. The brushless motor has 3 power lines from the motor. Brushed motors have 2 power cords from the motor.
6-Check wiring
Check the wiring around the scooter. Check all connectors to make sure they are plugged in. Check the leads coming out of the connector to make sure they are still connected. Do not pull any leads to avoid damaging the connector during inspection.
Check the wiring for any scratches or frays. This is most common when the wire is wound around hard edges or frayed, and the wire may bounce or move a lot.
If your electric scooter only works sometimes, there may be a loose connection somewhere in the system. Sometimes it works, but sometimes it doesn’t. Due to a loose connection, the circuit may bounce off, close and return.
7-Check the speed controller
The speed controller will be connected to the battery, motor, throttle and brake. It can also be connected to any display on your scooter. This is really the brain of your electric scooter. Check all connections on the speed controller. Smell for a burnt smell. If any switch or transistor in the speed controller burns out, it will not work. If this is the case, it needs to be replaced. Check your electric scooter manual to find out where to buy replacement parts for the new controller.
8-Check the brake lever switch
The brake lever on the electric scooter has a switch that can turn off the motor when you step on the brake. It is usually an on/off switch somewhere on the brake lever. If this switch does not work or is stuck in the “brake on” position, then your motor will not run. You can check this switch with a multimeter. It should be open circuit or closed circuit when braking. It should be the opposite when the brake is released.
9-Check the battery
The battery in a scooter is one of the most complex and important components. If you have not reached the previous speed and range, the battery may be where you need to repair the electric scooter.
The battery will consist of many batteries. This can be connected in batches in series and parallel. If you have a lithium polymer or lithium ion battery, you may also have a balanced circuit. Go here to learn more about lithium batteries.
If your electric scooter is not as fast as before, then the battery is the culprit. The motor has a value called k, which rotates at a specific RPM under a given input voltage. As the voltage drops, the motor spins more slowly.
When the battery is fully charged, each battery in the battery will output a certain voltage. For different battery types, this number is different. If your battery has 10 batteries connected in series, its output voltage is 10 times that of a single battery. If one battery in the battery pack fails, its output voltage is 9 times that of a single battery. If 3 batteries are broken, then it will output 7 times the voltage, and so on.
If your 10-cell battery has 3 bad batteries, then you can only run at 70% voltage. Your motor will only spin at 70% of the RPM of 10 qualified batteries.
It is very common for a single battery to be damaged in a battery pack. You can use a multimeter to check the voltage of the battery pack after it is fully charged. It should be equal to or slightly greater than the specified full battery voltage. It is a few volts missing, and there is a bad battery in your battery.
When your battery is discharged, its output voltage will decrease. The output of a battery pack with 30% remaining capacity will not be as much as the output of a full battery pack, so your scooter will slow down.
As your scooter battery ages and goes through more charge/discharge cycles, its capacity will decrease. Its peak voltage will also decrease, which means your scooter will slow down. This also means that your scooter won’t go that far. If your scooter battery has been in use for more than a few years, it may be time to replace it with a new battery pack. The average service life of an electric scooter battery is between 2 and 5 years, depending on the intensity of use.
Find a repair shop
If you have reviewed the list and cannot find the problem, it may be time to take it to the repair shop. Repairing electric scooters is easy, but some problems may require more experience. The first thing to check is your scooter manual to see if they have a place to send it in for repair. If your scooter is new and unusable, please send it back. Don’t dig your scooter too deep, if it is new, you may not be able to return it for a refund.
Many scooters are produced in China and there is no customer service or support in the United States. In this case, it is time to seek help elsewhere.
Some bike shops will repair electric scooters, but many will not. You can also try a general electronics repair shop. The hobby shop is another good place to try. Many electronic devices in electric scooters are the same as remote-controlled airplanes or cars.
