2.1.4.6 Hazard Event 6:Voltage Surges on the Primary Electric Supply <br />Voltage surges on the primary electric supply are expected to be largely mitigated by <br />voltage monitoring and corrective actions taken by the BMS and design of rectifier. <br />The rectifier complies with UL IEC 62368-1 and the Ericsson Energy Storage System <br />6160 including the Ericsson Enclosure B160 cabinet are listed as a system to UL 9540 <br />which includes testing for resistance to voltage surges on the primary electrical <br />supply. <br />Table 8 –Voltage Surges on the Primary Electrical Supply Barriers <br />a site in the event of a thermal runaway event.To <br />be added by customer. <br />Fire Service Response In the event of fire,fire service response is <br />beneficial.As the installation locations of cellular <br />communications equipment are generally in <br />populated areas,timely response and site access by <br />fire services are anticipated. <br />Barrier Barrier Description <br />THREAT BARRIERS <br />Battery Management Systems <br />(BMS) <br />BMS provides supervisory actions and isolation / <br />protective actions.Battery designed and tested for surge <br />high residual voltage from OVP/SPD,Ericsson internal <br />requirements and is listed in UL/IEC62368. <br />The E6160 has SPD on AC side and the complete power <br />system is tested for Voltage surge according to <br />UL/IEC62368 and GR-487 and GR-1089. <br />Over Voltage Protection The battery charging system includes over voltage <br />protection.The E6160 has SPD on the AC side and the <br />complete power system was tested for Voltage surge <br />withstand according to UL/IEC62368 and GR-487 and <br />GR-1089. <br />Cell Electrical Abuse Tolerance Cell tested and certified to UL 1973.Cells and modules <br />were tested to UL 9540A and did not propagate fire <br />outside the initiating module. <br />CONSEQUENCE BARRIERS <br />Confidentiality Class External Confidentiality Label Document Type Page <br />Ericsson Internal Analysis 23 (27) <br />Prepared By (Subject Responsible)Approved By (Document Responsible)Checked <br />ERATLEN Thomas Lennholm <br />Document Number Revision Date Reference <br />1785-BFM 107 220/1 Uen PA2 2025-06-03
