Electromagnetic Compatibility Evaluation of Wireless Charging Systems for Public Spaces

Almost worldwide, various agreements and regulations are enacted and vigorously enforced to address long-lasting climate change. Public transport with conventional combustion engines is affected by driving bans in restricted areas in cities. Nevertheless, electric vehicles with conductive charging are not suitable for all applications, e.g. taxis. That is due to the high daily route distances and the irregular waiting periods in queues (taxi on demand). As a solution to this problem, wireless charging for taxis in a public space is developed and realized in the project TALAKO. In this context, a guaranteed safeguarding of the electromagnetic environmental compatibility (EMCE) is essential so that the developed system is not a hazard to the health of humans and animals. This paper addresses the investigation of the resulting magnetic fields in the context of wireless power transfer for taxis in public areas using numerical simulation methods. Furthermore, the analyses are compared by field measurements.
