Electrostatic charging of vehicles being driven and stopped

In this work, the electrostatic charging of vehicles was intensely investigated in the dry climate of Spain. The vehicles used in this study include forklifts, passenger cars, vans, trucks and tractor-trailers, loaded and unloaded. The measuring results obtained while these vehicles were being driven and stopped are presented in this work together with the variables identified. An equation on the potential of two rubbed objects given by Schön was applied on the charging process of tire and street yielding a calculation that simulated the measured potentials on the vehicles body within the experimental scatter. Based on this calculation, safety conclusions and recommendations for threshold limits were derived.
