In this episode dr. Francesco Restuccia from  Kings College London takes me on a journey through different types of batteries, and what fire challenges relate to them. We discuss how the batteries burn, and how internal systems (Battery Management System) influence that behavior. From the size and type limitations to the potential perils of a cell thermal runaway, the fire spread in the whole batteries, and feedback loops that we need to understand to create safer systems. We'll also shed light on the contrasting battery lives of consumer electronics, laptops, and cars, as well as some challenges in the second life of batteries. In the final leg of our journey, we will tackle the complex world of modeling batteries and their management systems, touching on the challenges of over-constraint equations and calculating heat release rates from off-gassing.
