The battery modules used in our Octave battery cabinets are certified and designed for top-notch electric vehicles. They were built to withstand extreme conditions. On top of that, we use continuous monitoring to ensure performance of the battery systems. More than one million data points are logged per battery system per day. We analyze the behavior of the battery cells and their degradation based on their history. Battery measurements such as temperature, current levels, and depth of discharge significantly impact the lifetime of batteries and are closely monitored. This unlocks data-driven predictive maintenance possibilities: we forecast when to replace a used battery module, and by doing so, extend the lifetime of your entire system.
