SAFETY MANAGEMENT OF ROAD LIGHT DUTY BEV CRASH THROUGH NEW ASSESSMENT TOOLS BASED ON REAL EXPERIMENTS AND MULTI-PHYSICS DETECTION SYSTEMS

Ziel

Key priorities of BEV crash include passengers rescue ensuring safety of first responders, with efficient and timely firefighting measures. Fire, explosion and toxic gases are risks related to a lack of state of safety (SoS) evaluation and rapid detection of thermal runaway (TR) events. Additional risks concern BEVs’ fires extinction, requiring massive quantity of water with pollution consequences. SOCRATES addresses these challenges developing an advanced system for early detection of battery faults, reducing detection time by 50% vs. current detection based on temperature monitoring only. The system includes risks assessment functions and enables rapid and standardized warning from the vehicle to the rescue teams. Crash tests supported by simulations at different scales will optimise sensing architecture, associated to novel multi-physics SoS algorithms to assess risk levels, prioritize rescue measures and evaluate remaining useful life (RUL) and reuse of the battery, therefore complementing the Digital Passport. This early and precise detection will also lead to emergency cooling designs, preventing TR to escalade. Fire extinction and extrication procedures will be developed with firefighters’ units in Europe, to reduce time event up to 50%, and water amount up to < 5 000 L for 1 crashed BEV thanks to efficient cooling strategies and media. Vehicle level demonstrations will improve safety guidelines and recommendations for first responders, OEMs and policy makers. The consortium gathers OEMs, large companies, RTOs, insurance companies and firefighters from 5 European countries, adopting a circular approach, with samples sourced from scrapped BEVs. World class platforms for tests, simulation and data processing will be provided to bring a post-crash safety system to TRL6. The results will be scalable to large automotive volume with impact on further European standards and worldwide crash operational procedures.
