This document covers the general physical, electrical, functional, testing, and performance requirements for a mechanized (hands free) conductive power transfer system primarily for transit buses using an overhead coupler capable of, but not limited to, transferring DC power. It defines a conductive power transfer method including the curbside electrical contact interface, the vehicle connection interface, the electrical characteristics of the DC supply and the communication system. It also covers the functional and dimensional requirements for the vehicle connection interface and supply equipment interface.
On-route conductive solutions are attractive to heavy duty applications where down-time resulting from charge operations need to be minimized and the operator prefers to make the connection without leaving the driver's seat. The existing SAE charging standards do not address on-route conductive charging solutions that serve to promote all day operation of high capacity electric vehicles.
