Electrification for use by industries, including electrical mobility and distributed power generation applications, inevitably requires more batteries. This is obvious in rapidly growing transportation applications like automobiles and drones, and gaining prominence for energy storage and development of more electric aircraft. These batteries are not standalone but complex parts of larger systems that must operate optimally to ensure safe and efficient energy usage. Battery management systems (BMS) include both hardware and embedded software for real-time monitoring and control of rechargeable batteries to provide reliable power in complex applications. ANSYS solutions for embedded software and functional analysis enable BMS development for secure, dependable and efficient battery operation.
