Recently, the International Organization for Standardization (ISO) approved seven new international standards projects for new energy vehicles (NEVs), led by China. These projects cover key areas including electric vehicle (EV) design, power batteries, fuel cells, and battery swapping. In addition, two specialized working groups for fuel cell vehicles and battery swapping vehicles have been formed, with Chinese experts serving as conveners.
The newly initiated vehicle standards include "Electric Road Vehicles - Safety Requirements - Part 4: Post-Collision Electrical Safety" (ISO/AWI 6469-4), a revision jointly led by China and Japan. This update focuses on adjusting requirements for voltage reduction and energy release in the event of a collision, aimed at improving vehicle safety and strengthening passive protection mechanisms. Another project, "Electric Road Vehicles - Road Performance - Part 1: Passenger Cars and Light Commercial Vehicles" (ISO/AWI 8715-1), will revise testing conditions, loading mass, and test methods for the acceleration performance, top speed, and hill-climbing capabilities of light electric vehicles, thereby standardizing EV performance testing methods.
For power battery standards, two new projects, "Electric Road Vehicles - Power Battery Packs and Systems - Thermal Management System Testing Methods - Part 1: General Testing" (ISO/AWI TS 25344-1) and "Electric Road Vehicles - Power Battery Packs and Systems - Thermal Management System Testing Methods - Part 2: Liquid Cooling/Heating Systems" (ISO/AWI TR 25344-2), aim to establish global standards for assessing the performance of thermal management systems in electric vehicle batteries, providing robust support for worldwide evaluations.
In the fuel cell sector, two additional projects—"Fuel Cell Road Vehicles - Fuel Cell System - Air Compressor" (ISO/AWI 25356) and "Fuel Cell Road Vehicles - Fuel Cell System - Hydrogen Recirculation Pump" (ISO/AWI 25361)—will help guide the technological advancements of fuel cell engines and fuel cell electric vehicles, ensuring industry-wide consistency and development.
For battery swapping systems, the new standard "Electric Road Vehicles - Battery Swapping Electric Vehicles" (ISO/AWI TR 25656) will define key components, performance requirements, terminology, classifications, and application cases for battery-swapping EVs. This standard is expected to facilitate the global adoption of battery swapping technology.
