SAE J3105 Standard Promotes the Safe Testing and Performance of Mechanized Conductive Power Transfer Systems<\/p>\n

SAE International, announced today it has published its latest standard, SAE J3105\u00ae: Electric Vehicle Power Transfer System Using Conductive Automated Connection Devices<\/a>, along with three new tributary documents. The standard 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 direct current (DC) power.<\/p>\n

According to a report published in 2019 by P&S Intelligence<\/a>, the U.S. electric bus market size is projected to reach $1,948.5 million by 2024. The market growth is primarily driven by several federal, regional, and state grants and incentive programs. In addition, low cost of ownership, coupled with low maintenance cost of electric buses, specially battery electric buses (BEB) is expected to benefit the market during the forecast period.<\/p>\n

As the market expands, the need for the continued standardization of DC power distribution remains, and SAE J3105 addresses the many interfaces required to ensure power delivery is consistent. SAE J3105 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.<\/p>\n
