The "Most Critical Component" of Electric Scooter/Bikes

The "most critical components" of electric scooters/bikes are batteries, motors, controllers, and chargers.

The batteries of electric scooters/bikes are usually divided into lithium batteries and lead batteries. As mentioned in the article How To Charge Electric Scooters In Winter?, Kugoo electric scooters/bikes are powered by lithium batteries.

Generally, the batteries of electric scooters are: 24V, 36V, 48V, 60V, 64V, among which 36V and 48V are the most common.

Commonly used 36V batteries are: 36V10AH and 36V12AH, while individual electric scooters also have 36V14AH, 36V17AH and 36V20AH batteries.

Commonly used 48V batteries are: 48V10AH, 48V12AH, 48V14AH, 48V17AH, 48V20AH.

Kugoo Warm Reminder: In order to extend the service life of the electric scooter, please store the electric scooter in a cool and ventilated place.

The motor of an electric scooter/bike is the component responsible for converting the chemical energy of the battery into forward kinetic energy. The greater the power of the motor, the greater the maximum speed that the electric scooter/bike can travel, and the stronger its climbing ability.

There are two common motors on the market: brush motors and brushless motors.

Brushed motor: A brushed motor is a rotating motor that contains a brush device that converts electrical energy into mechanical energy. Generally, when a brushed motor is in use, the carbon brushes inside the motor will continue to wear, which will cause certain losses, and the carbon brushes need to be replaced regularly.

Brushless motor: The brushless motor is composed of a motor body and a driver, and is a typical mechatronic product. Generally, the Hall element is used to sense the position of the permanent magnet, and then the direction of the current is controlled to achieve the commutation effect.

Electric scooter/bicycle manufacturers generally use brushless and gearless motors. The cost of its speed control system is higher than that of a brushed high-speed motor, and its service life is longer.

According to the working voltage, the motors can be divided into: 12V, 24V, 36V, 48V, 60V, 64V, etc. The most commonly used is the 48V motor.

According to the power, the motors can be divided into: 180W, 250W, 350W, 500W, 800W, 1000W, etc. The most commonly used are 350W and 500W motors.

The controller of the electric scooter/bike is to control the running state of the electric scooter, including: speed adjustment, brake control, lamp control, fault prompt, power prompt, buzzer prompt, switch machine control, etc.

According to the difference of function and structure, it can be divided into two types: brush controller and brushless controller.

According to the working voltage, it can be divided into: 24V, 36V, 48V, 60V, 64V, etc. The most commonly used is the 48V controller.

According to the output power, it can be divided into: 180W, 250W, 350W, 500W, 800W, etc. The most commonly used controllers are 350W and 500W.

Precautions for the use of the controller:

  • 1. It is strictly forbidden to connect the positive and negative poles of the power supply in reverse, otherwise it will cause serious damage to the controller.
  • 2. The plug-in terminals must be in good contact and not loose, otherwise it will cause unpredictable failures and consequences.
  • 3. It is necessary to ensure that the working voltage is within the reasonable working voltage range of the controller to ensure the reliability of the controller.
  • 4. It must be ensured that the power of the controller and the motor are matched correctly.

The charger of an electric scooter/bike is also one of the "most critical components". After all, the battery is to provide power for the electric scooter/bike, and the charger is to replenish energy for the battery.

Electric scooters/bikes usually use switching power supply chargers, because this charger has the characteristics of power saving and high efficiency.

The correct operation of the switching power supply charger is: when charging, first insert the battery, then add the power; when it is full, first cut off the power, and then unplug the battery. If you pull the battery plug first when charging, especially when the charging current is high (red light), it is very easy to damage the charger.

In daily use, we must follow the following points to store the charger of the electric scooter/bike:

  • 1. Waterproof and moisture-proof.

As an electronic product, accidental ingress of water or exposure to humid air when it is not used for a long time will cause different degrees of corrosion or oxidation to its internal electronic components.

  • 2. Anti-drop and anti-vibration.

The charger is actually a very fragile component, and the internal components cannot withstand being beaten. Especially to prevent accidental landing during use. Do not throw, knock or shake the charger. Please note that rough handling of the charger will destroy the internal circuit board.

  • 3. Anti-potent chemicals.

Do not use harsh chemicals, cleaning agents or strong detergents to clean the charger. To remove the external stains on the charger, use cotton dipped in a small amount of absolute alcohol or clean water to scrub.

  • 4. Anti-static during cleaning.

Clean the charger and charging port regularly. When cleaning, wipe gently with a damp cloth or an antistatic cloth. Do not wipe with a dry cloth.

  • 5. Prevent cold and heat.

Do not place the charger in a place with excessively high temperature. High temperature will shorten the life of electronic devices, destroy the charger, and deform or melt some plastic parts. Do not store the charger in a place where the temperature is too low. When the charger is working in a very cold environment, when the internal temperature rises, moisture will form in the charger and destroy the circuit board.

Of course, the display of the electric scooter/bike is also a very important part. We can judge the speed, battery status, mileage, etc. of the electric scooter/bike through the data of the display, so that the rider can ride more safely. Therefore, in daily use, the maintenance of the monitor cannot be ignored.
