Thermal runaway prevention

Peter Donaldson speaks to experts who are working on cell design and chemistry to avoid thermal runaway Protection from thermal runaway in an electric vehicle (EV) battery requires a holistic solution that affects every aspect of the pack’s design and operation. The consensus seems to be that protection options are limited to prevention and mitigation rather than stopping a runaway once it has started.

Phase change materials

Phase change materials offer intriguing possibilities in the thermal management of EV powertrains as Nick Flaherty explains Phase-change materials (PCMs) are known for their superior latent heat capacity, acting as heat absorbers without notable temperature increases. This property can be used in many different ways throughout the powertrain of e-mobility systems, from enhancing the heat transfer in the power electronics to cooling the entire battery pack
