The new energy battery industry is undergoing a profound transformation—from scale expansion to technology-driven upgrades. With solid-state battery pilot lines entering production in 2026, the global Battery Management System (BMS) market projected to exceed USD 14 billion, and Power Conversion Systems (PCS) for energy storage rapidly scaling alongside the development of next-generation power systems, these three trends are redefining the boundaries of battery testing. Against this backdrop, this article examines the evolving testing requirements and key challenges across the new energy battery industry, and explores the technological evolution of test equipment in three critical dimensions: power capability, channel density, and energy regeneration.

With the rapid development of battery technology, from consumer electronics to electric vehicles and large-scale energy storage systems, batteries have become the core energy carriers, making performance testing crucial. However, traditional battery testing methods — such as using real batteries or simple DC power supplies and electronic loads — often suffer from low efficiency, high cost, safety risks, and limited test scenarios.
