ABSTRACT
The article offers information on the procedures to detect internal thermal-runaway failures in lithium-ion batteries. According to the author, thermal-runaway failures happened due to poor cell or battery-pack design, errors in manufacturing, external fatigue and insufficient charger or system design. Prevention of such system failure could be avoided by detecting signs such as excessive block voltage drop, long taper-current charging times and cell heating during cell charging.
