Wireless Charging System for an Electric Autonomous Micro-transit Transportation Vehicle

This paper details the design, testing and implementation of a wireless charging system for an autonomous micro-transit transportation (AMT) vehicle. Specifically, the paper covers the topology, controls, preliminary experimental results and integration approach within the Ecological personal transport (EcoPRT) autonomous vehicle. The SAE J2954 standard was used as a guideline for the systems overall mechanical and electrical design. The described system layout and methodology may be used in other autonomous charging applications in which power usage is high and frequent charging is required. Examples of this include autonomous vehicles used for both transportation and industrial applications. Experimental results of a scaled down lab set up are reported, detailing closed loop control of the constant current charging process and zero voltage switching behavior of the inverter output.
