Energy storage systems are becoming increasingly important as a means of supporting renewable energy sources such as wind and solar power. As these sources are intermittent, energy storage is necessary to smooth out fluctuations in energy supply. However, the increasing use of energy storage systems also brings new safety concerns. Energy storage devices can generate significant heat during operation, and this can lead to thermal runaway and even fire.

We all remember last year when Tesla’s large energy storage equipment burned, causing a fire at a substation in the United States. According to professional analysis, the thermal runaway of the battery was the leading cause of the fire. Therefore, how to effectively prevent thermal runaway has become an essential part of energy storage system safety.

Infrared thermography

In recent years, infrared thermography has become an increasingly popular technology for the monitoring and analysis of energy storage systems. Infrared thermography can help to mitigate these risks by providing a non-invasive means of detecting hotspots and other potential problems. By analyzing the thermal signature of an energy storage device, it is possible to identify areas that are generating excess heat and to take corrective action before a catastrophic failure occurs.

One of the key advantages of infrared thermography is its ability to provide real-time data. By using infrared cameras and other equipment, it is possible to monitor energy storage systems continuously and to detect changes in thermal behavior as they occur. This enables operators to respond quickly to any potential problems and to take corrective action before they escalate.

In addition to providing a means of detecting potential hazards, infrared thermography can also be used for routine maintenance of energy storage systems. By analyzing the thermal signature of a device over time, it is possible to identify trends and to make predictions about future behavior. This can help operators to plan maintenance activities more effectively and to minimize downtime.

Infrared thermography can also be applied to the emergency mobile EV charging system, which as an energy storage and EV charging device, also needs to monitor the battery temperature. Of course, this kind of function needs to be customized. In addition, our Emergency mobile EV charging system is equipped with a temperature monitor. Each cell in the battery has temperature monitoring. Once the temperature is 50 too high, the system will stop working and “battery abnormality” will be displayed on the screen. In addition to temperature monitoring, it is also vital to have fire suppression devices. However, when an open fire is detected, the fire extinguishing device inside the machine will spray powder to extinguish the fire and protect your property to the maximum extent.

In the context of a sustainable world, energy storage devices will see a new upsurge, and therefore their safety becomes crucial. SETEC POWER will continue to invest in innovation to help promote the development of green energy.
