European Urban Battery Safety Intelligence (EUBSI) aims to make electric urban mobility safer by helping operators to identify battery instability before it develops into a serious fire.
As cities deploy more electric buses, scooters and other electric fleets, large numbers of lithium-ion batteries are increasingly concentrated in depots and charging hubs. Battery failures can escalate rapidly, producing hazardous smoke, damaging vehicles and infrastructure, disrupting transport services and creating risks for workers, passengers and nearby communities.
EUBSI will develop and validate a predictive early-warning service that uses available vehicle, battery and charging information to identify unusual behaviour and calculate battery risk in real time. Controlled laboratory testing will also study electrical, thermal and acoustic signals that may appear before thermal runaway. Where useful, acoustic sensing can provide additional information.
The system will translate these signals into clear risk levels, alerts and recommended actions, helping operators to stop charging, isolate an affected vehicle or take other preventive measures before a situation escalates.
The project brings together EPTTAS, Transport for London, Ryde Technology, the Danish Technological Institute, the Acoustic Emission Service and Forsters Communications. The solution will be validated through electric bus and micromobility operations across European urban environments between 2026 and 2028.
The expected result is a scalable safety intelligence service that supports earlier intervention, reduces high-risk exposure and service disruption, and strengthens confidence in the continued expansion of zero-emission urban mobility.

Lithium-ion battery fires can escalate rapidly in depots and charging hubs, causing toxic smoke, infrastructure damage, service disruption and safety risks.
EUBSI turns existing fleet and charging data into early risk signals, alerts and response guidance so operators can intervene before battery failures escalate.
Safer electric mobility through earlier intervention, reduced high-risk exposure, fewer service disruptions, validated pilot deployments, and scalable battery safety intelligence for European cities.
