Study on the evaluation of energy consumption economy for electric vehicles

Based on the analyses of the evaluating indicators of electric vehicle (EV) energy consumption economy, the mathematical model for computing the economy of energy consumption of EVs under four different driving modes of acceleration, constant speed, deceleration and idle speed was established. The EV application circumstances were studied by EV experiments and the rules of energy consumption under different ambient temperatures were obtained. Taking E-bus for example, the analysis and computation of the economy of energy consumption under the combination driving mode were carried out, and the feasibility of the EV economy model was validated.
