Beam Global received a patent from the European Patent Office covering its Phase Change Composite material for lithium-ion batteries, titled “Smart Phase Change Composite for Passive Thermal Management.”
The European patent expands on the company’s existing US patent and extends intellectual property coverage to Europe. Beam Global said the material is intended for passive thermal management, limiting heat transfer in cold conditions and reducing battery temperatures in high-heat environments.
For electric vehicles (EVs) and charging-adjacent battery systems, passive thermal control can support more consistent performance across temperature extremes and may reduce reliance on active cooling. Beam Global said the material is designed to accommodate expansion when hot and contraction when cold, which can help maintain pack integrity under temperature cycling.
In a North American context, where EVs and energy storage systems are increasingly deployed across diverse climates and outdoor environments, passive thermal management approaches may play a growing role in addressing durability, safety, and cost challenges. As EV architectures move toward higher energy density and higher voltages, advances in passive thermal control could influence engineering tradeoffs related to cooling system complexity, power consumption, and lifecycle performance.
