Projects:2014S1-04 All Electric Vehicle for City Use

This project is a continuing project from 2008. The aim of the project in this year is to build an electric vehicle driving system to achieve the road test and data logging.

Project information

Motivation and Background

• Facing the increasing air pollution and Carbon Dioxide emissions, the electric vehicle is a feasible alternative choice of traditional vehicles with internal-combustion engines.
• The most significant electric motor control principle applied in this project is the Field Oriented Control (FOC). In the operation, two phase currents of motor are sampled and converted into a two co-ordinate time invariant system by Clarke Transformation and Park Transformation. By controlling the converted torque component, we can achieve the torque control as well as speed control.

Previous work

Based on the works in previous years, the battery and charging system with its monitoring system are completed. For the motor driving system, the Semikron SKAI5001 inverter which is embedded TMS320F2407 DSP is used as the main electronic device to achieve the DC-AC transform. However, the tests on Semikron inverters are failed in last year. Thus, the motor control project should be built on the new inverter and DSP.

Project Aims

In this year, the project aims to build a control system of the Prius electric motor based on the FOC theory. To realize this target, the relevant devices including Resolver to Digital converter, current sensors, DSP and inverter are required.
