Situated in Longquanyi District, Chengdu City, Sichuan Province, this project includes a 5MW/10MWh energy storage system. It enables the battery manufacturer to conduct efficient off-grid and grid-connected drag tests, analyze the comprehensive performance of batteries in practical applications, identify potential issues in a timely manner, and optimize design and usage strategies to enhance product performance and lifespan. When drag testing is not required, the system operates in planned curve mode to achieve peak shaving and valley filling for commercial and industrial applications, helping enterprises save energy and improve efficiency.
