EviKon Thermal Runaway Detector
The E2673 thermal runaway detector is a maintenance-free, long-life sensor that was specifically designed to detect early-stage off-gassing from lithium-ion batteries:
Battery energy storage systems (BESS)
Data centres and UPS rooms
EV charging infrastructure
End-of-journey facilities
Domestic garage applications● RS485
The Evikon E2673 detects H₂ and VOCs (electrolyte vapours, including DEC and DEMC) to provide early detection of battery thermal runaway and off-gassing that mitigates risks associated with lithium-ion battery failures. In addition, the product measures relative humidity and ambient temperature, helping local systems to keep these parameters at acceptable levels, reducing risks of electrostatic discharge, short circuits and equipment overheating.
Features
● Hydrogen & VOC leak detection
● Humidity & temperature measurement
● Compact DIN-rail or wall-mount design
● Maintenance-free, long-life sensors
● Alarm relays (2 for alarms, 1 for fault)
● RS485 Modbus RTU interface
Having the RS485 Modbus RTU communication protocol and three relay outputs for alarms and fault signalling, the product ensures flexibility and seamless compatibility with most of the fire safety and SCADA systems. The compact form factor allows installation even in space-constrained BESS and data centre battery racks.
