Batteries are ubiquitous in our modern lives, ranging from small cells powering IoT devices and mobile phones all the way up to high-capacity batteries fueling electric vehicles. Being able to accurately model and emulate batteries across wide power ranges is therefore essential to guarantee reliable performance for small through large scale devices and development efforts. In this session, Keysight will show new software and hardware solutions that support the precise modeling, emulation, and life-cycle testing of batteries from milliwatts up to hundreds of kilowatts.
