Design and Development of a Driving Condition Collector for Electric Vehicles

For the sake of obtaining a battery consumption model of reasonable accuracy for electric vehicles, this paper designs and develops a driving condition collector which can achieve the state of charge (SoC) information by interfacing a battery management system. It adds location and time stamps as well as other driving-dependent sensors, creating a spatio-temporal stream. A window-based application, called a road data analysis mapper, manipulates the SoC streams and plots the change in sensor readings, such as slope, speed, temperature, and the like. The battery consumption statistics are collected using this device as a series of battery remaining values in Jeju city. To allow drivers to estimate the battery consumption between two points, actually a subsequence of the whole stream, the power consumption to each evenly spaced reference points is interpolated.
