This plan aims to provide a motor drive system for electric vehicles (EVs), which will integrate the latest power electronics technology, advanced motor control strategies, and an efficient battery management system to optimize the power performance of electric vehicles, improve driving efficiency and safety, and extend battery life.

Plan composition

Power converter (inverter):

The use of silicon carbon (SIC) semiconductor based inverters can provide higher thermal efficiency and faster switching frequency, which helps to improve the power performance and operational efficiency of the entire vehicle.

Motor Control Unit (MCU):

The motor control unit adopts advanced digital signal processors (DSP) or microcontrollers (MCU) to achieve precise control of motor operation. Integrate advanced control algorithms such as vector control and field oriented control (FOC) to ensure that the motor operates at optimal efficiency.

Battery Management System (BMS):

Design an efficient battery management system to monitor the battery status in real-time, including voltage, current, temperature, etc. By precise state estimation (SOH, SOC) and balance management, battery life can be extended and driving range can be increased.
