Battery Check
Ensure the battery is fully charged.
Test the functionality of the battery charger and make sure it is correctly charging the battery.
Battery Check
Motor Assessment
Check if the motor makes unusual noises or overheats during operation.
Overheating can cause a reduction in speed; repair or replace the motor if it is damaged or faulty.
Motor Assessment
Tire Check
Use a pressure gauge to check the tire pressure.
Maintain the recommended pressure levels. Check the tire tread for wear and replace worn tires.
Tire Check
Controller Check
Ensure all wires in the controller compartment are properly connected and insulated.
Look for any obvious damage or loose connections, and any exposed or worn wires.
Controller Check
Mode Setting Verification
Select the appropriate mode based on the desired speed and terrain conditions.
Make sure it is not inadvertently set to low-speed mode.

For Engineers

Cause Analysis

The reason for slow vehicle operation may be a faulty motor, but in most cases, it is a problem with the battery pack. Testing the battery pack is the best method for troubleshooting.

If the battery pack is old, worn out, or faulty, it may cause the vehicle to move slowly or not function properly.

Solutions

Deep Charging
Sometimes, a lead-acid battery pack needs a deep charge to balance the cells and help restore capacity. Try charging the battery pack for 48 a 72 hours and then see if it helps. It’s good practice to perform a few deep charges annually or when significant capacity loss is noticed.
Visual, Tactile, and Olfactory Inspection
Remove the pedal or wiring cover and look for any burned or melted wires, wire connectors, or electrical components.
Also look for loose, desconectado, or damaged wires or wire connectors. Pull and push all individual wires and wire connectors to ensure they are not loose or disconnected.
Get close to the speed controller and motor and smell them. Any parts that look burned or melted, or smell like burned plastic, are almost always defective and should be replaced to prevent damage to the speed controller.
Testing 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 vehicle and check if there is an illuminated indicator light on the battery charger. If the indicator light on the battery charger lights up, this means the wiring and wire connectors connected to the charger port are good, and the charger port itself is also good. Not all battery chargers have an indicator light that illuminates when the charger is only plugged into the vehicle, so if the light does not come on, you should perform 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 charger port should match the voltage level of the battery pack. If the charger port has male terminals, you need to be very careful to avoid shorting the terminals or the charger port housing (if it is metal).
Testing the Battery Charger
  • Ensure there is voltage at the charger port, then test the voltage of the battery or battery pack to confirm if it needs charging.
  • Plug the battery charger into the charger port on the vehicle and into the wall, then use a digital multimeter to test the voltage of the battery pack.
  • If the voltage rises gradually, it indicates the charger is charging the battery. Continue charging until the indicator light shows a full charge, then test the battery voltage to confirm if it has reached a 100% charged state.
  • If the charger fails to charge to 100%, there may be a fault.
Testing the Battery Pack
Remove the battery pack from the scooter and take out individual batteries to load-test their cells.
You can then test each battery using an automotive battery load tester.
Most entry-level automotive battery load testers apply a 100-amp load to the battery, which is too high, so a variable carbon pile battery load tester should be used and adjusted to apply a 30-amp load to the battery.
Testing the Battery Pack Voltage
After reading the voltage, you can use the battery charge state chart page to determine the percentage of the charge state.
A good battery or battery pack will be at 100% charge state after being discharged and left for a few minutes, or if stored. If the battery pack does not rebound to a 100% charge state within a few minutes after being discharged, it indicates the battery or battery pack is faulty or worn.
When a battery pack has been charged to a 100% charge state and its voltage drops below 100% charge state after being left for some time, this indicates the battery pack is faulty or worn.
Good batteries and battery packs will recover to a 100% charge state within a few minutes after the vehicle has been driven.
Inspecting the Motor
Look for any burned or melted wires or wire connectors on the motor. Burned or melted wires or wire connectors indicate the motor overheated, which could cause the plastic insulation to melt off the copper windings of the motor.
Smell the motor for any burnt plastic odor. If the motor smells burnt, it indicates the windings overheated. Motors with overheated windings should always be replaced to prevent damage to the speed controller.
If the insulation on the copper windings melts, it will cause a short circuit and result in the motor not running or running slowly. Short-circuited motor windings can also burn out the speed controller by providing excessive resistance, causing it to work too hard and overheat.
