Monitoring electric vehicle performance

The third generation of electric vehicles are under development. Electric vehicle performance is still being verified by monitoring and testing the latest advances in technology. The performance of electric vehicles are measured by many different parameters. The type and accuracy of sensors that are available for measuring vehicle performance has improved with time. Modern testing equipment varies from indicator lights to automated computer data acquisition systems. The design of the data acquisition system depends on the evaluation to be preformed. There are four types of data collection and storage systems being used on vehicles: display, recording, processing and integrated systems. These are briefly outlined. The authors then discuss the components of a data acquisition system, the measurable parameters, and system considerations.
