With the popularity of the concept of intelligent transportation, electric vehicles have gradually become the first choice for short-distance transportation with their energy-saving, environment-friendly, economical and convenient features. According to the global consulting firm "Frost & Sullivan", China's electric vehicle market size is expected to grow from RMB 65.64 billion to RMB 108.99 billion from 2019 to 2023 at a compound annual growth rate of 7.22%, and the electric vehicle industry will become a blue ocean market with a scale of 100 billion.

 

An electric vehicle is composed of a motor drive, power supply system, and control system. It has the advantages of cost-effectiveness, low use cost, and fast speed.

 

betway必威 APM32 series industrial-grade general-purpose MCU has the advantages of low power, high performance, high integration, and easy to transplant. It supports a 96-bit unique device ID (UID) with 8kV ESD, meets the industrial reliability standards, and has strong anti-interference and anti-static capabilities. The operating temperature of the full range of products is -40℃~+105℃, which meets the temperature requirements of a harsh operating environment, and can provide safe and reliable embedded application solutions for the electric vehicle industry.

APM32F103 Series MCU Electric Vehicle Motor Control Solution

 

· Efficient processing: Based on the latest Arm® Cortex®-M3 core with a maximum operating dominant frequency of 96MHz.

· Large storage space: Flash: 16-512KB, SRAM: 6-128KB, configured with enhanced external memory controller EMMC.

· Support-CAN communication module and comply with 2.0A and 2.0B (active) specifications.

· Support mainstream FOC algorithm library, with high conversion efficiency, effectively reducing controller temperature rise and extending battery life.

· The Hall sensor is used as the synchronous signal. FOC is used to realize the sine wave control mode to ensure the stable operation of the motor.

· Built-in FPU supports floating-point multiplication, which helps to improve the angle operation speed and accuracy of the Hall sensor.

· Support floating-point trigonometric function operation, which is conducive to arctangent operation and high-frequency injection without sensor and observer, and the generation of sine wave pulse injection signal.

· It has certified IEC61508 and USB-IF and meets the industrial high-reliability standard
