Evikon E2673 is an off-gassing detector designed for early detection of thermal runaway in lithium-ion batteries. It simultaneously measures hydrogen (H₂), volatile organic compounds (VOC), relative humidity and temperature, covering the most important environmental parameters in battery energy storage systems and data centres with a single device.
The E2673 is designed for applications where there is a risk of gas release from lithium-ion batteries or where air quality around high-current equipment needs to be monitored. Typical installations include battery energy storage systems (BESS), data centres and UPS rooms, electric vehicle charging infrastructure, and battery manufacturing plants. Its compact aluminium enclosure measuring 94 × 56 × 32 mm allows installation even in space-constrained battery racks – directly on a DIN rail or on the wall using the supplied mounting bracket.

For hydrogen, the detector uses the thermal conductivity principle with a range of 0–100 %LEL and a resolution of 0.02 %LEL. For volatile organic compounds (including DEC and DEMC electrolyte vapours released during cell degradation), a MOS sensor is used with an index range of 0–500. Warm-up time is up to 1 minute, and response time is up to 20 seconds. Sampling is by diffusion – gas reaches the sensors through natural air circulation, so no pump or sampling line is required.
In addition to gases, the detector also measures relative humidity in the range 0–100 %RH and ambient temperature in the range -40 to +85 °C with accuracy of < 2 %RH and < 0.3 °C. Monitoring these values helps reduce the risk of electrostatic discharge, short circuits and equipment overheating – so there is no need for a separate environmental sensor.
The detector features three SPST relays with NC logic – two for alarms and one for fault indication, rated at 300 mA / 30 VDC. For integration into higher-level systems, it is equipped with an RS485 bus using the Modbus RTU protocol (19200 baud), allowing the device to be connected to standard fire safety systems as well as SCADA. Status is indicated by three LEDs – power (green), fault (yellow) and alarm (red).
Factory settings:
During degradation and thermal runaway of lithium-ion cells, a mixture of gases is released – the most typical include hydrogen and electrolyte vapours (volatile organic compounds, e.g. DEC and DEMC). Hydrogen is generated rapidly when the cell vents, while VOCs may appear earlier during slower off-gassing. Detecting both groups simultaneously makes it possible to identify cell failure at an earlier stage than monitoring only one type of gas.
There are two options available. The first is three SPST relay outputs with NC logic (300 mA / 30 VDC) – two for alarm states and one for fault indication. These are suitable for direct connection to a fire safety control panel or simple input cards. The second option is RS485 with the Modbus RTU protocol (19200 baud), which allows the device to be integrated into SCADA, BMS or another building management system and all measured values to be transmitted digitally.
Yes. The hydrogen alarm threshold is user-adjustable within the range 10–40 %LEL H₂, so it can be tailored to the project requirements or fire safety design. The sensor’s actual detection range remains 0–100 %LEL.
The enclosure measures 94 × 56 × 32 mm, so it fits even into space-constrained BESS and data centre racks. It is normally mounted on a DIN rail, or directly on the wall using the mounting bracket supplied as standard. Detection is by diffusion – gas reaches the sensors through natural air circulation, so no pump or sampling line is required.
IP40 means the enclosure is protected against the ingress of solid objects 1 mm and larger, but it is not protected against water. The detector must therefore be installed indoors (BESS cabinet, data centre, plant room) – not outdoors or in locations where it could be directly sprayed. Gas enters by diffusion through the device enclosure.
