Dr. Challa of DFR Solutions

You want to be proactive about the safety of your battery-powered product. Is qualifying your battery manufacturer to industry standards enough? The answer is that most compliance-based testing is related to abuse tolerance, but the vast majority of battery field failures happen under normal operating conditions.  Compliance based testing is necessary but not sufficient to ensure lithium ion battery safety and reliability.

In this presentation Dr. Vidyu Challa discusses broad categories of lithium ion battery field failures using industry data from 2005 onwards, whether abuse tests are relevant to field failures, and major areas where risk mitigation strategies should be implemented.  She discusses manufacturing defects, abuse tolerance, adequacy of battery protection systems, end product battery application integration tolerance and battery usage conditions and how they contribute to failures.
