Dynamic match and optimizing design of electric vehicle powertrain

The principle of power performance and energy economy of an electric vehicle (EV) powertrain is analyzed and the operation character of acceleration pedal is studied in the paper. The performance analyzing system of EV is developed based on the dynamic driving schedule. Then, using this tool, the principle and method for matching and optimizing the EV powertrain are discussed based on the actual development of an EV. The analysis results are proved by actual tests.
