Modern battery test systems continue to evolve, providing new capabilities to address changing technology and business needs. Key battery test technology trends include higher voltages for faster charging, wider power ranges, faster response times to emulate real-world conditions of e-mobility, and more environmental testing with broader adoption.
Battery test solutions have evolved from manual testing to automated and next-generation battery test systems. This article describes the evolution of these methodologies over time to align with the evolving test requirements.

Many automated test systems do not easily integrate with third-party tools and as a result, limits testing capability and takes a long time. The ability for a battery test system to interface with and control an entire test environment is critical.
Engineers need to have a connected ecosystem of flexible battery test systems and software automation tools to efficiently test batteries, validate performance and scale testing. EV battery test solutions have evolved from manual testing to automated & next-generation battery test systems to address more complex test challenges.
NI solutions are at the forefront of battery cell test system technology. These integrated hardware and software solutions are optimized for building automated test systems and advanced analytics with a reduced physical footprint. This approach enables comprehensive testing throughout the production line without time or space constraints.
Automated battery test systems integrate an electronic DC source and load within a single product along with advanced built-in automation tools and improved measurement capability. These test systems range from custom-engineered to commercial off-the-shelf (COTS) options.
