Thermal Runaway Monitoring

Thermal runaway is an uncontrolled rise in a battery’s temperature due to exothermic reactions. This creates a feedback-loop where heat accelerates internal reactions, producing even more heat. This overheating can lead to gas buildup, fires, and/or explosions if not managed. It’s important to mitigate thermal runaway risks and is essential for protecting your operations and investments.
Early Detection: The Key to Prevention
Identifying the early signs of thermal runaway is crucial. In lead-acid batteries these signs can include:
-
Increased internal and case temperatures (when compared to ambient)
-
Charge current increase
-
Swelling/bulging of battery case and external connectors
-
Abnormal cell/bloc voltages
Monitoring key parameters in real-time allows for swift intervention before a minor issue escalates into a catastrophic one.
Your First Line of Defense
The SC4 Site Controller Unit is a monitoring system that offers unparalleled protection for your battery installations. Using the SC4’s built-in thermal runaway detection algorithm, you’ll get early warning of an event long before it ever becomes a hazard. Focusing on the key indicators of a thermal runaway, the algorithm closely monitors:
- Cell/block temperature
- Ambient temperature
- Float current
Additionally, the SC4 provides monitoring of other key aspects of a battery’s health that may change during a thermal runaway event, such as:
- Voltage (cell/block and string)
- Resistance of the internal structure of the cell/block as well as connecting hardware
- Discharge current
Required components: SC4, Float Current Monitoring System, Remote Input Module and temp sensors.
Optional components: Battery sensors, Remote Output Module.
Explore the SC4
- Sends SNMP traps to relay information when a threshold is reached per the set points.
- Up to 6 strings of batteries on a single SC4 controller (up to 40 batteries per port).
- Webpage access through the assigned IP for remote access to data.
- Files available for download through the web page.
- Changes to the configuration can be made remotely with admin privileges. Firmware can be updated remotely as well.
