For quick desktop analysis, use alongside the Cell Guard Development Kit.
Introducing Cell Guard, a cutting-edge CAN-based sensor designed to revolutionise battery system monitoring. This versatile device measures absolute pressure, air temperature, Volatile Organic Compounds (VOCs), absolute air water content, relative humidity, dew point temperature, and acceleration. With configurable CAN bus speed and address, and an included CAN DBC file, Cell Guard integrates seamlessly into virtually any battery system, providing early detection of cell venting and moisture formation.
Cell Guard features a low power mode that continuously monitors the environment, transmitting data only when a set threshold is exceeded, thereby conserving energy. Additionally, its low side drive function pin, capable of 500mA, can be triggered when programmable thresholds are met, ensuring prompt response to critical conditions.
Equipped with a 5-pin automotive-rated Molex Nano-Fit Power connector, Cell Guard’s compact size and lightweight design allow for easy installation in most vehicles and energy storage systems. Developed in accordance with ISO26262 and rigorously tested to meet automotive standards, including ISO7637-2 2011, ISO 17650-2 2012, and ISO 17650-4 2010, Cell Guard ensures reliability and performance. Enhance your battery system’s safety and efficiency with the state-of-the-art Cell Guard sensor.
