Immersed Commercial and Industrial Energy Storage Cabinet Standard

This enterprise standard, issued by Shandong Electrical Engineering Times Energy Technology Co., Ltd., specifies the technical requirements and test methods for the DGSD-EES-100K-232L (A)-D immersed commercial and industrial energy storage cabinet. It covers product model meaning, parameters, structure and appearance, clearance and creepage distances, system insulation resistance, and comprehensive BMS functions including status upload, fault diagnosis, electrical protection, and management. The standard details data monitoring, charge/discharge settings, protection thresholds, energy management, data export, emergency stop, access control, and water immersion protection. It also addresses grid adaptability such as frequency, voltage, power quality, active/reactive power regulation, overload capability, three-phase unbalance, harmonics, DC component, and unintentional islanding protection. Performance metrics include charge/discharge response, regulation, and conversion times, rated energy, power conversion efficiency, off-grid operation parameters, protection degree IP54, noise, temperature rise, battery disturbance limits, and various immunity tests. Test methods are provided for structure inspection, clearance/creepage distance, insulation resistance, and BMS functions.
