Metis Engineering Unveils Cell Guard, A Groundbreaking Battery Health Sensor for EVs and Energy Storage Systems

Metis Engineering has introduced Cell Guard, an innovative battery safety sensor designed to transform battery health monitoring for electric vehicles (EVs) and Energy Storage Systems (ESS). The cutting-edge sensor offers unparalleled accuracy and detailed information on the health of lithium-ion battery packs, enhancing longevity and detecting early signs of catastrophic battery failure, significantly lowering the risk of thermal runaway.

Current battery cell monitoring systems (BMS) primarily offer temperature and voltage sensors. Cell Guard, however, monitors a variety of environmental parameters, including VOCs, pressure change, humidity, dew point, and an optional accelerometer to record shock loads. The comprehensive data can be cross-checked with other inputs to detect cell venting, which helps prevent thermal runaway. The sensor also offers a programmable pin that can control a relay if a threshold is reached.

With Cell Guard, Metis Engineering is redefining the standard for advanced battery health monitoring in EVs and Energy Storage Systems. By increasing safety, reducing risk, and offering unprecedented insight into battery condition, the sensor provides peace of mind for EV drivers and ESS manufacturers, potentially promoting the wider adoption of electric vehicles and Energy Storage Systems.
