The electric bicycle controller plays a very important role in the smooth operation of the electric bicycle. If you do not pay attention to the maintenance of the electric vehicle controller in peacetime, it will fail due to various reasons. The reasons for the failure of the electric bicycle controller are roughly the damage of the power device, the damage of the internal power supply of the controller, the intermittent operation of the controller, the wear of the connecting line and the loss of the control signal caused by the bad or falling off of the connector. Let’s learn how to maintain the electric vehicle controller.
Reasons for the failure of the electric vehicle controller:
Electric bicycles have many small but important parts and the electric bicycle controller is one of them. Don’t look at the inconspicuous controller, you can rely on it to start, advance, retreat, and stop your electric bicycle.
1.The power device is damaged.
The damage to the power device generally has the following possibilities: damage to the motor; poor quality of the power device itself or insufficient selection level; device installation or loose vibration; motor overload; damage to the drive circuit of the power device or unreasonable parameter design.
2.The internal power supply of the controller is damaged.
The damage to the internal power supply of the controller generally has the following possibilities: the internal circuit of the controller is short-circuited; the peripheral control components are short-circuited; the external leads are short-circuited.
3.The controller works intermittently.
The controller works intermittently, and there are generally the following possibilities: The parameter drift of the device itself in a high-temperature or low-temperature environment; the overall design power consumption of the controller is large, which causes the local temperature of some devices to be too high and the device itself enters a protection state; Bad contact.
4.The wear of the connecting line and the poor or falling off of the connector cause the loss of the control signal.
The wear of the connecting wire and the poor contact or falling off of the contact plug generally have the following possibilities: the selection of the wire is unreasonable; the protection of the wire is not complete; the crimping of the connector is not firm.
How to maintain the electric vehicle controller?
1.The electric vehicle controller must first pay attention to waterproofing.
Install the controller in the seat tube, in the cab, or in a place high above the ground to prevent flooding in rainy weather. Usually, it is necessary to pay attention to the cleanliness of the appearance of the controller, which is conducive to heat dissipation and prolongs the service life of the controller.
2.The controller lead plug should be kept clean.
This is also the weak link that affects the controller. When the lead wire and plug of the controller are soaked in polluted rainwater, they should be cleaned with water or alcohol in time to avoid oxidation and rust and prevent the controller from failing due to a false connection.
3.The controller cannot be overloaded for a long time.
Over time, the internal components of the controller are likely to be aged, the performance of the controller will be reduced, and the car-making car will be noisy and lack power.
4.Be careful when braking.
Excessive action or frequent braking will cause damage to the electric vehicle controller and affect riding safety. Especially on rainy and snowy days, braking needs to be cautious.
