Maintenance details of key parts of electric bicycle

We know that electric bicycles use batteries as auxiliary energy sources and have two wheels, which can realize human riding, electric or electric assisted special bicycles. Although it has the appearance characteristics of ordinary bicycles (even the appearance characteristics of motorcycles) .But the main thing is that it is a mechatronics personal vehicle that installs a motor/controller/battery/switch/handle and display instrument system on the basis of an ordinary bicycle.

  •  Frame parts

Frame components include frame, front fork, handlebar and other electric bike parts. The upper end of the front fork part is matched with the handlebar and the frame, and the lower end is matched with the front axle and front wheel parts to form the guiding part of the electric vehicle. The front fork frame can be flexibly rotated relative to the front tube of the frame, and the front fork can be driven by turning the handlebar to change the direction of the front wheel. In addition, the front fork also plays an important role in maintaining the balance of the electric vehicle when driving.

  • Motor

According to the magnetic field structure, the ebike motor can be divided into excitation type, permanent magnet type, and hybrid type; according to the general mechanical structure of the motor, it can be divided into brush type and brushless type; according to the shape structure, it can be divided into column type and Wheel hub type. The most commonly used classification method is divided into brush motors and brushless motors according to the way the motor is energized. The use of a high-tech permanent magnet brushless DC motor, because there is no brush, no rotating gear, there is no mechanical wear of the brush. Therefore, it has no interference, long life, high efficiency, reliable operation and simple maintenance. Compared with the brush motor, the disadvantage is that the control system is complicated and the cost is higher. Even so, it will be the development trend of the DC drive motor.

  • Controller

The controller is the core control device used to control the start, run, advance and retreat, speed, stop, and other electronic devices of the electric vehicle. It is like the brain of the electric vehicle and is an important part of the electric vehicle. Parts. The controller is a component that controls the speed of the motor, and is also the core of the electric system of the electric vehicle. It is designed with multiple protection function control systems, with undervoltage, current limiting or overcurrent protection functions. The intelligent controller also has a variety of riding modes and a self-checking function for the electrical components of the vehicle. The controller is the core part of electric vehicle energy management and various controller signal processing. Stepless speed regulation, soft start, under-voltage protection, over-current protection and brake power-off, etc. Protect the motor and the battery, so that the current can be output in a controlled manner to generate the required power without burning the motor.

  • Batteries

 Batteries are on-board energy sources that provide energy for electric vehicles. Currently, electric vehicles mainly use a combination of lead-acid batteries. The battery of the Hotebike electric bicycle is a lithium battery, which can be used repeatedly and the effect is better.

  • Charger

The charger is a device that supplements the battery with electrical energy. It is generally divided into two-stage charging mode and three-stage charging mode. Two-stage charging mode: first constant voltage charging, the charging current gradually decreases as the battery voltage rises, when the battery power is replenished to a certain level, the battery voltage will rise to the charger’s set value, and then it will be converted to trickle charging. The charger design adopts a three-stage automatic conversion method of constant current, constant voltage, and floating charge to protect the battery and effectively extend the battery life.

Tips for usage: When charging, keep the charger well ventilated. If you smell peculiar smell or the temperature of the charger case is too high during charging, please stop charging immediately and check and deal with it.
