ICE Vehicle Energy Consumption Measurement and Calculation Methodology for the Purpose of EV Battery Pack Design

Abstract

This paper presents a standard vehicle’s energy consumption calculation for the purpose of an electric vehicle (EV) battery pack design procedure. The vehicle dynamics parameters were measured on a route located on a mountainous terrain with a standard driving profile. Vehicle used to conduct the measurements, was a standard internal combustion engine (ICE) vehicle. Afterwards the measured parameters have been used as inputs to a vehicle dynamics model to calculate the resistive forces "on the wheels" that the vehicle had to overcome to achieve the desired driving profile on the specified route. Those forces are then used to calculate the average energy consumption of the vehicle on the mentioned route, only to be scaled to the battery pack with the use of the powertrain model. Furthermore, the consumptions of the vehicle’s onboard electrical devices are added to receive the complete energy consumption of the vehicle on the specified route with the desired driving profile. The before mentioned average energy consumption (in kWh/km), can be then used for further application of this vehicle model in different scenarios.
