Abstract
BACKGROUND: This study addresses the reasonable selection of key parameters for traction electric motors (TEMs) used in single-flow drivetrain of electric vehicles (EVs) or series hybrids considering requirements including achieving maximum velocity, climbing gradients, and meeting specified acceleration times. Traditional approaches for selecting internal combustion engines only consider maximum speed operation. As an example, calculation results are provided for a passenger car with specifications representative of a compact-class vehicle, which is highly suitable for urban environments.
AIM: Proposal of the method for selecting main TEM parameters based on mathematical modeling of electric vehicle dynamics in order to enhance vehicle performance and energy efficiency.
METHODS: 1) Study design: Computer simulation of vehicle dynamics; 2) Study subjects: Parameters of a compact-class electric passenger vehicle; 3) Study duration: Unlimited computational driving cycles; 4) Primary objective: Optimal TEM parameters (nominal/peak power, torque, rotational velocity); 5) Assessment methods: MATLAB simulation modeling with analysis of three key modes: Maximum velocity, 20° gradient climbing, Acceleration from 0–100 km/h within 14 seconds.
RESULTS: For the compact-class vehicle (1580 kg), the nominal TEM power was determined as 22 kW and peak power as 55 kW. The maximum shaft rotation velocity reached 8,000 rpm.
CONCLUSION: The proposed method optimizes TEM parameters for urban electric vehicles, improving energy efficiency while reducing production costs.
