Electric Safety Challenges with a Conductive Electric Road System—Chassis Potential Modeling and Measurement

Abstract

Conductive Electric Road Systems (ERS) appear as a promising solution for the electrification of transportation, particularly for heavy vehicles and long-distance trips but also for light vehicles. Significant research efforts are currently devoted to the development of conductive ERS systems, with up to four pilot test sites with different technologies in operation only in Sweden. With the help of electric models and experimental measurements on a pilot test track, this article assesses the potential safety challenges associated with one aspect of this technology: the absence of a reliable protective earth connection while the vehicle is connected to the ERS power supply. The results highlight the importance of monitoring the chassis potential at all times and the need of an active safety mechanism to disconnect the vehicle from the ERS supply if a severe fault occurs.

Research on Audit Simulation of Accounting Computerization Based on Internet Complex Discrete Dynamic Modeling Technology

“…However, the discrete dynamic system with only boosting algorithm will be affected by external environmental factors, resulting in system errors and inaccurate data processing [13]. Many subsequent researchers also added gradient enhancement and LS-Ensem methods on the basis of boosting algorithms [14]. e complex discrete dynamic system combined with the above algorithm can accurately and efficiently process the data required for calculation and analysis and finally realize the system model construction of data audit and control of accounting computerization [15].…”
