Research on Range Extended Electric Vehicle Based on Cruise

Abstract

Recently, extended-range electric vehicles are a new solution to energy shortage and environmental pollution, which effectively increases the range of electric vehicles, extends the battery life, and reduces fuel consumption. Therefore, this paper mainly focuses on the design of the EREV powertrain, building a vehicle model by using AVL CRUISE to simulate and verify the calculated parameters of the design. Analyzing the structural characteristics of the extended-range electric vehicle and determining the vehicle’s basic parameters and performance indexes using the Aratou Free 4WD hybrid as the prototype were the first part. In this part, the drive motor on the power system, battery, and range extender were selected based on the calculated parameters. The AC asynchronous motor, ternary lithium battery, and four-stroke gasoline engine were chosen as the components of the power system in the EREV. Building the vehicle model by using the AVL Cruise and developing the calculation tasks such as cyclic driving conditions, steady-state driving performance analysis, full-load acceleration performance calculation, and hill-climbing performance analysis were the second part. After the above steps, the simulation results analysis report showed that the powertrain design meets the target and potential of electric vehicle development. This paper provides a reference for comparing the dynamic property and economy of the extended-range electric vehicle with traditional fuel vehicles.
