CharIN Megawatt Charging System: 4 th Event Summary Report

Abstract

Medium- and heavy-duty electric vehicles require higher charging power levels than are supported by present light-duty EV charging standards. The Charging Interface Initiative (CharIN) Megawatt Charging System (MCS) Task Force is undertaking efforts to develop a new high-power charging standard for medium- and heavy-duty vehicle electrification. The fourth MCS evaluation event at NREL focused on thermal and mechanical performance evaluations of high-power MCS electric vehicle charging connectors and inlets from several different manufacturers, at current levels up to 3000A. Additionally, the event evaluated the performance of a reference inlet design, which will provide a baseline level of thermal performance for use in future evaluation and certification efforts of MCS connectors.
