SAE J3105-1:2020 pdf free.Electric Vehicle Power Transfer System Using Conductive Automated Connection Devices Infrastructure-Mounted Pantograph (Cross-Rail) Connection
This document details one of the connections of the SAE J3 105 document. The connections are referenced in the scope of the main document SAE J3105. SAE J3105/1 details the infrastructure-mounted pantograph, or cross-rail connection. All the common requirements are defined in the main document; the current document provides the details of the connection.This document covers the connection interface relevant requirements for an electric vehicle power transfer system using a conductive ACD based on a cross-rail design. To allow interoperability for on-road vehicles (in particular, buses and coaches), one configuration is described in this document. Other configurations may be used for non-standard applications (for example, mining trucks or port vehicles).
According to SAE J3105, the infrastructure-mounted pantograph is one type of ACD charging system that transfers power between the infrastructure and the vehicle. This power transfer occurs when the correct alignment is complete and the ACD moves into place to electrically connect the infrastructure and the vehicle through conductive connection.
The unidirectional WL AN patch antenna should be installed on the roof near the onboard DC conduction rails. Its location should consider alignment with the offboard antenna on the ISC side. Figures 7 and 8 provide the onboard vehicle positioning requirements of the unidirectional WL AN patch antenna relative to the DC conduction rails.
The maximum slope of the road in the sideways direction will be Angles A and B in Figure 11, including the kneeling of the bus. This will shift the top of the bus relative to the centerline, so the displacement caused by the road angle or kneeling should be considered while calculating the maximum and minimum distance between the pole and the street curb. Table 4 defines the angular dimensions.
