ABSTRACT
Increasingly stringent environmental protection requirements and the implementation of the most modern technologies compel automotive manufacturers to develop the production of environment-friendly vehicles with electric drive systems. In difficult road conditions, vehicle participants are exposed to various hazards, especially to health and life. This forced the Automotive Industry Institute (PIMOT) to attack the important problem named “Electric Vehicles’ Operational Safety (EVOS)”, which is related to a number of new issues, not sufficiently explored yet. The tests carried out until now on electric vehicles to check their conformity with the Regulations and Directives in force do not cover many issues that were identified within this project as having an important impact on vehicle riding safety and comfort. This work included the formulation and implementation of a three-level EVOS examination and assessment concept. This article presents results of comparative testing and assessment of the EVOS level for four electric vehicles, i.e. Mega E-City, Citroen C-Zero (Mitsubishi i-MiEV car manufactured by Citroen under a licence), Renault Fluence, and Opel Ampera. The presented results of testing the sample electric vehicles show how much the vehicles differ from each other and how much work still has to be done for improvement of the safety of their operation. Based on the work results, detailed EVOS assessment criteria may be prepared.
