With the development of urban transportation and the popularization of two wheeled electric vehicles, as a low-carbon and 

environmentally friendly short distance transportation tool, more and more people are joining the use of two wheeled electric 

vehicles. However, have you ever had the experience of riding an electric bike on the road and suddenly needing to adjust the 

speed or mode, only to find yourself at a loss? Or do you want to record your cycling data but cannot view it in real-time? 

These issues can all be solved through the protagonist we are going to talk about today - the Bluetooth module. 

(The Daxia Longque BT04-E model has a beautiful price, with dual-mode and single-mode options, small size, and multiple 

functions, making it very suitable for the controller industry)

In order to achieve intelligent control and better user experience for two wheeled electric vehicles, Bluetooth modules have 

been widely introduced into the controllers of electric vehicles. The electric vehicle controller is one of the important 

components of the electric vehicle, mainly responsible for controlling the speed and steering of the electric vehicle motor, 

as well as controlling the battery pack and motor's power and current parameters, so that the electric vehicle can obtain 

appropriate power output in different road surfaces and conditions.

Advantages of Bluetooth controller:

1.Vehicle condition monitoring: The Bluetooth module allows users to monitor real-time vehicle condition information of two 

wheeled electric vehicles. By connecting the Bluetooth module through the mobile app, users can view important data such as 

battery status, vehicle speed, mileage, voltage fluctuations, etc., in order to timely grasp whether the vehicle is in good 

condition.

2.Fault detection: Bluetooth connection enables users to obtain real-time fault codes and diagnostic information. When an 

electric vehicle malfunctions, users can connect the Bluetooth module through the mobile app to diagnose and troubleshoot 

the problem, quickly locate the problem, and carry out repairs and repairs as soon as possible. At the same time, the 

Bluetooth module can also detect key parameters such as battery voltage, motor speed, and motor current to determine 

whether the controller is working properly. If there are abnormalities in battery voltage, motor speed, or motor current, the 

controller may malfunction, causing the electric vehicle to be unable to operate normally. By connecting the Bluetooth 

module through the mobile app, users can quickly locate the problem and choose to replace or repair the battery or replace 

the motor based on relevant information.

3.Drive mode selection: The Bluetooth module is located in the controller of a twowheel electric vehicle, and users can switch 

between different drive modes through the mobile app. According to actual needs, users can choose energy-saving mode, 

normal mode, or sport mode to flexibly adjust the power performance and energy efficiency of the entire vehicle in different 

environments, and can also set speed

limits. For example, users can set automatic transmission mode, and when the vehicle speed reaches the set value, the 

controller will automatically stop the motor drive and slow down. During this process, the user does not need to operate 

any buttons or handles. If the vehicle speed is too fast and exceeds the pre-set safe speed range, the controller will 

automatically activate the deceleration protection system to limit motor drive. In addition, the Bluetooth module also 

supports users to set the vehicle's steering angle and braking method.

4.Parameter debugging: The Bluetooth module also allows users to debug parameters through the mobile app. Users 

can flexibly adjust some parameters of electric vehicles, such as acceleration, brake energy recovery, etc., to meet personal 

driving habits and needs, and improve the driving experience. The application of Bluetooth module in the controller of 

two wheeled electric vehicles provides a more convenient and intelligent control and monitoring experience, which can 

meet the personalized needs of users for driving modes and speed limit settings. The fault diagnosis and debugging 

function helps users quickly diagnose and solve vehicle fault problems.
