Energy storage systems are subject to demanding design constraints, from safety concerns around thermal and electrical stress to reliability requirements for utility-scale and residential installations. Electrical design engineers must navigate risks such as thermal runaway, electrical faults and compliance with evolving global standards. At the same time, design teams are under pressure to maintain compact system footprints, minimize energy loss, and simplify installation and maintenance across a range of deployment environments.
The BESS designs of tomorrow incorporate high-performance components that promote thermal stability, reduce voltage drop and maintain strong mechanical and electrical connections. This includes the use of high-temperature materials, spring termination technologies and laminated busbars to enhance energy flow and minimize resistance. Compact, locking interconnects are critical for residential and commercial systems, where space efficiency must be achieved without sacrificing safety or power density. Additionally, tool-free, maintenance-free components are employed to streamline installation and reduce long-term system costs.
Molex helps engineers achieve these design goals with a wide range of hardware solutions for BESS applications, including high-temperature-rated connectors, enhanced contact protection features and globally certified components for improved safety and compliance. Laminated busbars, spring termination technologies and high-power cable assemblies aid in optimizing energy transfer and system uptime. For space-constrained installations, Molex offers miniaturized, high-current interconnects and solderless designs that simplify integration and maintenance, enabling engineers to deliver reliable, efficient and future-ready energy storage systems.
