The study of EV data collection and analysis based on Taiwan i-EV pilot project

The evaluation data of EV in motion or in charging is a new research to reveal the EV performance and user behaviour. ARTC (Automotive Research & Testing Center) is devoted to the study of EVs for years, and in charge of the data evaluation in Taiwan i-EV pilot project. With the project's purpose, ARTC designs the flow of this task. First of all, the data need to be gathered including status, speed, date/time stamp, battery SOC on the vehicle are automatically transferred to OBU (On-Board Unit) through CAN protocol. The OBU developed by ARTC sends the data via 3G/GPRS to data collection platform. Afterward, the data are processed and analyzed by statistical method to address the results such as the driving distance, the distribution of the battery SOC etc. There are two operational models from the EV pilot projects at megalopolises in Taiwan. One is service car for public affairs and the other is rental car for the public. The data present the differences between various areas and purposes. The outcomes can help the government to make policy, fleet to earn the largest benefits, and car factory to adjust the car design.
