range of parameters that provide a comprehensive assessment of battery health. Its ability to measure moisture, dew point, water ingress, and pressure changes contributes to maintaining an optimal battery environment. In addition, a variant of Cell Guard incorporates an automotive accelerometer, enabling the assessment of crash loads on battery packs, providing vital information for post-accident analysis. The first-to-market innovative
solution features an accelerometer to measure Shock load and duration up to +/-24G, relaying any shock data over a configurable CAN interface to a control unit, such as the vehicle’s ECU. By capturing and analysing this
data, Holdsworth highlights that vehicle owners and insurance companies can make informed decisions to ensure the longevity and safety of the battery, avoiding the unsustainable practice of needless scrappage if an EV is involved in a minor collision, in turn helping to drive insurance premiums down. The data will also inform if the battery pack can be used in a Second Life Application. “Having the ability to monitor impact forces on the battery pack

is valuable, especially in situations like car accidents where it is crucial to determine if the pack has surpassed its designated G ratings,” he says. “Currently, the collection and
accessibility of this data are lacking, resulting in many battery packs being unnecessarily discarded, even if they are still in good condition.” Holdsworth acknowledges that the
transition from an R&D version of the sensor to mass production posed significant challenges. However, Metis Engineering successfully mastered the production process, ensuring the availability of Cell Guard to the market. Looking ahead, the company plans to enhance its offerings by introducing an easy- to-connect system that allows multiple, daisy-chained, sensors to be integrated into energy storage systems seamlessly. “While battery safety is a
legitimate concern, the data-driven approach offered by Cell Guard ensures that batteries are kept within their intended parameters,” Holdsworth concludes. “Through continuous monitoring and early detection of potential hazards, Cell Guard provides peace of mind to manufacturers, owners, and the general public alike.”
