Energy storage DC/DC high-voltage box testing line

Energy storage DC/DC high voltage box (also known as “bi-directional DC/DC converter” or “high voltage distribution unit”) is the core power conversion component of the energy storage system, responsible for the voltage conversion between the battery pack and the DC bus, bi-directional energy transfer and system protection. Its test line needs to cover all-round verification of electrical performance, conversion efficiency, protection function, communication protocol and environmental reliability.

The DC/DC high-voltage box test line for energy storage is a key link to ensure the efficient, reliable and safe operation of the system, which needs to take into account high-precision electrical measurements, harsh environment simulation and intelligent data analysis. The future trend will be towards higher power density (SiC/GaN device testing), shorter test beats (parallel test technology), and deep cloud (remote monitoring and predictive maintenance).
