The battery is the heart of the escooter. It serves as the “fuel tank” for electric scooters, holding all the power used by the DC motor, lights, controller, and other accessories. Due to their superior energy density and durability, lithium ion-based battery packs will typically be found in electric scooters. The BMS (Battery Management System), which functions as the battery’s “brain” ensures that it runs as it should and is protected.
The battery capacity measured in Watt-hours increases with the size of the battery pack and leads to a rise in the total power, speed, and range. However, it will also mean carrying more weight.
You may consider how far you can go in a single charge? High quality ezeboostx9 batteries give you a range of 40-75km in a lightweight and compact design. Some scooters can also provide over 100km range per charge. It’s recommended to go with 36v or 48v batteries for safety concerns. The battery pack is one of the most expensive parts in an electric scooter. Generally the price of a battery is between $350 to $900.
Electric Motor is a “powerplant” of the escooters. Since batteries provide direct current all of the motor in electric scooters are DC motors. A DC motor or direct current motor is an electrical machine that transforms electrical energy into mechanical energy by creating a magnetic field that is powered by direct current.
DC Motor Illustration [1]
DC electric motors come in a variety of forms, but the brushless DC motor is the one that is used in escooters.
A brushless motor is a type of DC motor (BL motor or BLDC motor), also referred to as an electronic commutated motor (EC or ECM motor). This is a motor utilizing direct current electric power. It utilizes an electronic controller to turn on DC currents to the windings creating a magnetic field that successfully rotates in space and the permanent magnet rotor rotates by following. The controller adjusts the amplitude and phase of the DC current pulse to control the torque and speed of the motor.
The benefits of brushless motors over a brushed motor are high speed, high power-to-weight ratio, close to instantaneous torque and speed control (rpm), low maintenance, and high efficiency. Brushless motors find use in computer peripherals (printers, disk drives), portable power devices, and vehicles varying from automobiles to model aircraft.
Brushless Motors [1]
It’s very useful to know what type of motor your scooter has. Most of the modern escooters have the hub motors.Hub motors built right into the wheels.[1]
The controller is the brain of your escooter. It collects data from the battery, motor, throttle and electric brake(if available) and sends data out to each part.
Basically, the controller is an electronic circuit to direct and regulate power from the battery to the motor. When the rider turns or presses the throttle, the battery receives signals to release more or reduce power going to the motor. And if the electronic brakes are pressed the controllers will cut off the battery’s power supply to the motor leading the overall speed reduce or stop the escooter.
