Overview

Replicate the complex operating conditions of real-world battery systems in a controlled, repeatable test environment

The BMS is responsible for monitoring battery status, ensuring battery safety, and coordinating charging and discharging strategies. Whether for energy storage plants, electric vehicles, or backup power systems, sampling accuracy, protection logic, balancing strategies, fault recovery, and communication integration must all be verified prior to deployment.

Yingyue Electronics' BMS testing platform enables R&D, testing, and production teams to replicate critical operating conditions without relying on actual battery packs through battery simulation, temperature and insulation simulation, fault injection, and automated software workflows, thereby reducing validation risks and the costs associated with repetitive testing.

  • Supports R&D validation, engineering testing, production re-testing, and quality spot checks
  • Replacing high-risk testing of real battery packs with controlled battery simulations
  • Unified management of equipment control, testing procedures, data collection, and report generation
