key sensor features
The GAS-VOC sensor is available through OEM partners in select markets.

It is a plug and play sensor to detect off-gas and temperature events from Li-Ion batteries. Available as a standard, RS-485 or daisy chained sensor. VOC sensors are NOT recommended for monitoring liquid li-ion batteries as time between off-gas and fire can be as low as 2 seconds.

Sensors to monitor batteries The rise of lithium-ion batteries in energy storage systems has brought efficiency and compact storage solutions, but it has also introduced risks, particularly thermal runaway. This phenomenon, where batteries uncontrollably overheat, can lead to fires or explosions. Such situations usually arise from malfunctions, overcharging, or physical damage, emphasizing the necessity for sophisticated monitoring.

A key to early detection of battery issues lies in the identification of Volatile Organic Compounds (VOCs). These compounds are emitted when lithium-ion batteries are stressed or damaged, serving as early warning signs. Detecting VOCs is thus critical in preempting thermal runaway and other hazardous conditions. The presence of VOCs allows for timely interventions, like shutting down affected battery units, averting potential disasters.

Enter the GAS-VOC sensor, a technological marvel specifically designed for this purpose. Its UL 61010 recognition is a testament to its safety and reliability, crucial for monitoring systems in energy storage. The Underwriters Laboratories (UL) certification ensures that the sensor meets rigorous safety standards, vital for applications in high-risk environments. Additionally, the integration of ISO 17025 temperature sensors in the GAS-VOC sensor enhances its accuracy, making it a reliable tool for battery monitoring.

For optimal effectiveness, it's recommended to install one GAS-VOC sensor per battery rack. This ensures comprehensive coverage and more precise detection of VOC changes, which is more informative than absolute VOC levels. Such a setup provides a more nuanced understanding of the battery's health and enables quicker responses to potential threats.

In conclusion, the GAS-VOC sensor is not just a safety device; it's a necessary component in the modern energy storage landscape. Its ability to detect VOCs early makes it a key player in preventing thermal runaways, ensuring the safety and longevity of lithium-ion battery systems. For those looking to bolster the safety of their energy storage systems, the GAS-VOC sensor stands out as an essential investment.

Overall, a sensor that can detect both CO2 and VOCs is the best option for identifying off-gases or first venting events in lithium ion energy storage systems. By detecting these gases at an early stage, engineers can take action to prevent the escalation of a thermal runaway event and reduce the risk of explosions or fires.
