Abstract

Current electric vehicles (EVs) suffer from several drawbacks that prevent widespread public acceptance. Inductive power transfer systems (IPTS) seek to address range and battery life issues by allowing EVs to charge while in transit. This advancement would allow future infrastructure to meet rising demands while simultaneously making EVs more accessible and user friendly.

In order to investigate the durability of the technology, two full size slabs were cast with working electronics and structurally tested while monitoring electrical parameters. The primary focus of this work was to study the durability of the concrete slabs. The secondary focus of the study was to determine how well the technology works under a variety of realistic loadings.

Both slabs with the embedded IPTS were subjected to high cycle fatigue loading and then underwent monotonic loading to failure in order to confirm material properties.

During the fatigue testing both slabs experienced minor cracking; however, it was not until the upper limits of static testing that major failures occurred. Throughout the experiment, the embedded IPTS proved to be resilient and suffered little degradation in performance. The IPTS embedded in these concrete pads demonstrated reasonable durability with promise as a viable solution to the growing needs of the EV infrastructure.
