LION E-Mobility AG (LION; ISIN: CH0560888270), a manufacturer of battery packs for electric mobility and energy storage solutions, announced that its subsidiary LION Smart Production GmbH has partnered with Castrol to develop a new battery module for high-performance EV applications. The collaboration combines LION Smart's direct battery-cooling innovation with Castrol's advanced thermal fluids and battery thermal management expertise.
The partnership aims to improve battery thermal management for passenger cars, trucks, and battery energy storage systems (BESS) worldwide through direct battery cooling, a cutting-edge approach that facilitates fast charging and discharging of battery cells submerged in a lightweight dielectric fluid. Castrol ON EV Thermal Fluids will be used to enable superior heat dissipation, enhance power density, and improve battery lifespan and safety, according to internal testing compared to conventional indirect battery cooling systems.
The new battery module features a modular design for homogeneous temperature distribution and minimal temperature gradient within the cell. The structure maximizes the active cooled contact surface, while a 'single cell fuse' reduces potential propagation from internal short circuits. As a result, LION Smart has advanced battery temperature management, improving the efficiency of plug-in hybrids (PHEVs) through higher levels of energy recuperation, greater power at lower system cost, and increased operational safety.
The alliance is part of Castrol's strategic focus on direct battery cooling technologies and battery fluid innovation. The collaboration was highlighted at the recent Battery Show Europe, where experts from Castrol and LION Smart demonstrated the technology in action. Matthias Donner, VP Advanced Mobility and Industrial products at Castrol, stated: "Direct battery cooling is a transformative technology for EV performance and safety, and this collaboration is a significant step towards real-world deployment. Partnering with LION Smart allows us to demonstrate the full potential of Castrol ON EV Thermal Fluids in advanced battery systems." Michael Geppert, Head of Engineering at LION Smart, added: "Our battery system architecture is designed to push the boundaries of electrical performance in high-power applications, and Castrol's direct battery cooling expertise is a perfect match."
