What Are the Common Failure Modes of Energy Storage Systems?

There are a variety of failure modes common to energy storage systems, often resulting in fire, explosion, or the release of toxic gases. So what are some common failure modes of energy storage systems? Let's take a look together.


1. Thermal failure of the energy storage system


The energy storage system has a set operating temperature range, which is usually provided by the manufacturer. If operated outside the acceptable temperature range, the energy storage system may not work as expected, causing premature battery aging and possibly complete failure, resulting in fires and explosions.


Energy storage system thermal failures are caused by external sources that are the result of contact with a burning or overheated adjacent battery, high temperatures, or exposure to other external heat sources associated with battery storage or the environment in which the energy storage system is installed.


2. Electrical failure of the energy storage system


An electrical failure occurs when the battery is overcharged, charged too quickly, or has an external short circuit. This can also happen if the battery is discharged too quickly or if the battery is over-discharged below its specified termination voltage. Electrical failures can cause energy storage systems to become inoperable, overheat, fire, and explode.


3. Mechanical failure of the energy storage system


Mechanical failure occurs when a battery is physically damaged when it fails when crushed, penetrated, or otherwise deformed by mechanical force.


4. Internal failure of the energy storage system


Internal failures can be the result of poor design, the use of inferior materials, or defects in the manufacturing process.


5. Environmental impact of energy storage system


Environmental influences can cause battery failure. This can be caused by extreme ambient temperatures, seismic activity, flooding, corrosive mist, etc. entering the system, or rodent damage to wiring. If not properly controlled, some places with rapid temperature changes (such as mountainous areas) may experience condensation, causing internal damage to the outdoor energy storage system.


While there are many applications and advantages to using battery energy storage systems, there are also associated dangers. Understanding hazards and what causes them is only the first step in preventing them. At present, we have corresponding solutions for energy storage safety. To a greater extent, the safety of the entire life cycle of the lithium battery energy storage system is guaranteed.
