Abstract
In this article, the driving performance of two electric vehicles of the latest generation clean powertrain cars is evaluated. The vehicles under test are an electric Peugeot iOn, and an AGV electric version of the Ford Transit Connect. For different torque-speed operating conditions at wheel level, the vehicles are evaluated for their battery to wheel - electrical to mechanical - power conversion performance, with the help of chassis dynamometer testing. This generates an insight in the mapping of the consumption and efficiency value ranges for electric driving. The vehicles are also tested in real life on-road conditions, by following a pre-set representative track on public roads. Charging efficiency and consumption of auxiliaries is considered too. These tests give insight and realistic values to judge consumption, driving range and efficiency. With these results, further calculations and accurate simulations of realistic scenarios are possible
Highlights
Electric vehicles (EVs) are increasingly appearing on the market and on our roads
While measuring vehicle wheel torque and speed, for a number of operating points, electrical quantities at battery level are measured with dedicated monitoring systems
Chassis dynamometer tests have been performed for different constant speed and wheel torque operating points, and vehicle acclimatization and battery charging has been evaluated
Summary
Electric vehicles (EVs) are increasingly appearing on the market and on our roads. Due to their beneficial effects on health and environment, and as a means to further optimize energy use for personal transport, electric cars are of crucial importance for transportation [1]. The electrical quantities’ measurement and monitoring is performed with different mobile onboard acquisition systems, by acquiring access to the vehicle’s CAN bus or by installing electrical measurement equipment in function of the needs. Both commercial data loggers as well as dedicated developed systems are employed. Each vehicle is tested on-road, following a prescribed path, while traction battery quantities
