Detecting the safety risks before they become
dangerous

As with all energy sources, batteries carry a certain risk of failure. For lithium-ion batteries this can result in gassing and burning, potentially harming people and property. The ongoing trend towards even higher energy densities literally adds fuel to the fire. The relationship is quite simple: The more energy is stored within a single battery cell, the more energy is released in case of a failure.

It is therefore no surprise that homologation standards in the automotive sector have increased safety-related requirements significantly. Other markets are following this trend. Nevertheless, most of these measures are responding to a problem that has already escalated. On the other hand, extensive and intelligent monitoring, coupled with adaptive operating strategies, is the way to go to detect, predict and prevent safety critical issues before they escalate.

At ACCURE, we have specialized in safety monitoring using physics-based models and statistical approaches, way beyond the limited input and resources an on-board BMS can provide. Our battery monitoring detects safety-relevant anomalies before they become dangerous. Since 2020, ACCURE’s online diagnostics have correctly predicted and prevented several critical li-ion battery failures.
