Overview
ISO/TR 8713:2019 - Electrically Propelled Road Vehicles - Vocabulary is an internationally recognized terminology standard published by ISO. Developed by Technical Committee ISO/TC 22/SC 37, this technical report defines and harmonizes the vocabulary related to electrically propelled road vehicles. By establishing uniform terms and definitions, ISO/TR 8713:2019 supports clear communication and consistent interpretation across ISO standards in the field of electric mobility, including hybrid vehicles, battery systems, charging technologies, and safety aspects. This vocabulary is essential for manufacturers, regulatory bodies, researchers, and anyone involved in the development and implementation of electric vehicle (EV) technologies.
Key Topics
ISO/TR 8713:2019 covers a comprehensive range of concepts central to electrically propelled road vehicles and their sub-systems, including:
-
Vehicle Types and Configurations
- Electrically propelled vehicles (EVs)
- Hybrid electric vehicles (HEVs), plug-in hybrid vehicles (PHEVs), and fuel cell vehicles (FCVs)
- Vehicle classifications by use (bus, truck, etc.)
-
Electric Propulsion Components
- Battery systems, battery packs, and battery control units (BCU)
- Electric drives, energy storage devices, fuel cell systems
-
Charging and Energy Transfer
- Supply equipment, charging modes and cases
- Wireless power transfer (MF-WPT) systems and components
- Communication between vehicles and charging infrastructure (EVCC, SECC)
