Design considerations
For those who live near work or who want to find more expensive motor-controlled transportation, electric bicycles are increasingly becoming their favorite choice. While battery and motor technology has been rapidly developed, the speed and travel of electric bicycles are also constantly improving. Electric bicycles can use various components based on expected cost and design complexity.
The kernel subsystem includes:
Controller:
Usually includes detection, A / D conversion and output comparison components. Ultra-low power microcontrollers can be used in low-end systems, while C2000 digital signal processors can be used in complex systems with more functions.
Motor:
Electric bicycles usually use brushed or brushless DC motors. Although the brushless motor is more reliable and more efficient, it will increase the weight of the bicycle.
battery:
The battery type has undergone a development process from lead acid to lithium ion. Lead-acid batteries are widely used because of their low cost, but they are larger and heavier than lithium-ion batteries, and are not as environmentally friendly as lithium-ion batteries.
Power management:
Provide the power needed to run the function block and monitor battery activity. For low-end electric bicycles, a host controller with comparators and discrete devices can be used to manage lead-acid batteries. More complex electric bicycles use specific ICs that provide battery protection, monitoring, and fuel monitoring to provide users with important information about safety and lithium-ion batteries.
