AS 7486:2026

The objective of this document is to provide guidance to rail transport operators (RTOs) for the specification and utilization of onboard batteries and electric double-layer capacitors (EDLC) used for traction purposes (propulsion and braking). This document provides guidance to ensure that they are used safely, effectively and reliably in the Australian context and networks, throughout the life of the energy storage system (ESS). This document provides a basis for RTOs, vehicle manufacturers and ESS manufacturers to understand and communicate the requirements on ESS.The document provides guidance and an understanding of:• ESS design principles to support safety and reliability;• the ESS’s through life assessment factors;• the ESS testing and certification requirements; and• the hazards and risks associated with the ESS integration into vehicles.This document builds on existing national and international standards by providing additional guidance and requirements for ESS. See Appendix B for a summary of system and subsystem levels applicable to these standards.Performance based requirements, recommendations and guidance do not replicate existing published requirements and recommendations.The review updates AS 7527 to match current technology and better security needs. It adds stronger rules for cybersecurity and protecting data. It also includes more types of data, such as for remote vehicles, GPS, and passenger safety. The Standard sets clearer rules for data accuracy, timing, and how long data must be kept. It also requires regular checks and good maintenance of the system.
