The Manufacturer has also agreed to notify Intertek and to request authorization prior to using alternate parts, components or materials. COMPONENTS Components used shall be those itemized in this Intertek report covering the product, including any amendments and/or revisions. LISTING MARK The ETL Listing mark applied to the products shall either be separable in form, such as labels purchased from Intertek, or on a product nameplate or other media only as specifically authorized by Intertek. Use of the mark is subject to the control of Intertek. The mark must include the following four items: 1) applicable country identifiers "US" and/or "C" or "US", "C" and "EU" 2) the word "Listed" or "Classified" or "Recognized Component" (whichever is appropriate) 3) a control number issued by Intertek 4) a product descriptor that identifies the standards used for certification. Example: For US standards, the words, “Conforms to” shall appear with the standard number along with the word, “Standard” or “Std.” Example: “Conforms to ANSI/UL Std. XX.” For Canadian standards, the words “Certified to CAN/CSA Standard CXX No. XX.” shall be used, or abbreviated, “Cert. to CAN/CSA Std. CXX No. XX.” Can be used together when both standards are used. If all standards on the ATM have the same standard title, the shared title or its abbreviation may be used in place of the examples above. Example: "Medical Electrical Equipment" or "MEE"; "Information Technology Equipment" or "ITE"; "Audio/Video Information And Communication Technology Equipment" or "A/V ICTE". Note: A facsimile must be submitted to Intertek, Attn: Follow-up Services for approval prior to use. The facsimile need not have a control number. A control number will be issued after signed Certification Agreements have been received by the Follow-up Services office, approval of the facsimile of your proposed Listing Mark, satisfactory completion of the Listing Report, and scheduling of a factory assessment in your facility. MANUFACTURING AND PRODUCTION TESTS Manufacturing and Production Tests shall be performed as required in this Report. FOLLOW-UP SERVICE Periodic unannounced audits of the manufacturing facility (and any locations authorized to apply the mark) shall be scheduled by Intertek. An audit report shall be issued after each visit. Special attention will be given to the following: 1. Conformance of the manufactured product to the descriptions in this Report. 2. Conformance of the use of the ETL mark with the requirements of this Report and the Certification Agreement. 3. Manufacturing changes. 4. Performance of specified Manufacturing and Production Tests.

Due to particular testing requirements, some components may be requested to be shipped to specific labs. Thus, specific shipment destination(s) for each sample will be provided in the written notification. Managing CEC Location: Intertek Testing Services (Shanghai FTZ) Co., Ltd ETL Component Evaluation Center Building No. 86, 1198 Qinzhou Road (North) Shanghai 200233, China Attn: Ms. Emiliana Zhou Sample Disposition: Due to the destructive nature of the testing, all samples will be discarded at the conclusion of testing unless, the manufacturer specifically requests the return of the samples. The request for return must accompany the initial component shipment. Because Unlisted Components are uncontrolled, and they do not fall under a third party follow up program, Intertek may require these components to be tested and/or evaluated at least once annually, more often for certain components, as part of the independent certification process. The Unlisted Components in Section 5.0 require testing and/or evaluation as indicated.

NOTES ·DISCONNECTS (CBS) INSIDE THE B160 CABINET PER INDIVIDUAL BATTERY STRING - ALL ARE EXISTING AND TO BE RE-USED. ·ESS IS DC, NOT AC, THEREFORE IT SHOULD NOT BE INCLUDED IN THE MAINS LOAD CALCULATION. ESS/B160 IS CHARGED BY THE 6160 ALREADY IN THE LOAD TABLE. OVERVIEW OF BMS OPERATION IN BATTERY ENERGY STORAGE SYSTEMS, ONE OF THE MOST IMPORTANT HAZARD BARRIERS HELPING TO ENSURE SAFETY IS THE BATTERY MANAGEMENT SYSTEM (BMS). THE BMS PROVIDES PRIMARY THERMAL RUNAWAY PROTECTION BY ENSURING THAT THE BATTERY SYSTEM OPERATES WITHIN A SAFE RANGE OF PARAMETERS SUCH AS ITS STATE OF CHARGE AND TEMPERATURE. IN A UL 9540 LISTED BATTERY ENERGY STORAGE SYSTEM, THE BMS MONITORS, CONTROLS AND OPTIMIZES THE PERFORMANCE OF BATTERY MODULES AND DISCONNECTS THEM FROM THE SYSTEM IN THE EVENT OF ABNORMAL CONDITIONS. THE BMS ALSO PROVIDES CHARGE AND DISCHARGE MANAGEMENT OF THE BATTERIES. IN CASE OF UNDERVOLTAGE OR OVERVOLTAGE, OVER-TEMPERATURE, OR OVERCURRENT CONDITIONS, THE BMS WILL ALARM AND THEN LIMIT THE CHARGE AND DISCHARGE CURRENT OR POWER. UNDER EMERGENCY CONDITIONS, THE BMS WILL CEASE OPERATIONS AND ELECTRICALLY DISCONNECT THE BATTERY. ***NEW BATTERIES ARE TO BE INSTALLED IN THE EXISTING BATTERY CABINET.

Paralleled five active fuses are provided for secondary protection if the MCU and MOSFETs fail to isolate the battery from the external connection. The AFE (U202) samples the overall current value through the voltage across Rsense (Shunt Resistor) and receives the cell temperatures and voltages information via sensing circuitry. The MCU (U702) analyses the sampled values received by internal SPI communication from AFE and drive the MOSFET arrays in the P- negative path to stop charging or discharging in certain conditions, refer to Table 2. The BMS also provides RS485 interface for external communications and dry contacts for external alarms. Battery protection ICs U102 to U104 monitor the cell voltages and provide secondary protection by actively open the five active fuses FM201 to FM205 once the Permanent Failures Protection is triggered. The fuses are blown by a drive circuit which pull up the center tap of the heaters to P-positive. The system functional block diagram is shown in figure 1. Figure 1 - System functional block diagram Page 4 Atttachment 5 - Functional Safety Report CSA Report No. 305501-80245567 MASTER CONTRACT:305501 REPORT: 80245569 PROJEC: 80245569 Page No: 5 Date Issued: July 17, 2025 FSR-131, V7 Oct 2023 Safety Design The following contents describe the specific implementation principle for each safety function. 1. Cell Voltage Protection Function: BMS monitors the cell voltages by AFE (U202) and the sampling circuitry. Then the sampled voltage values will be transmitted to the MCU (U702) through the SPI communication. The MCU (U702) compares the sampled cell voltage with the threshold values. If the cell voltage exceeds the protection threshold, MCU output control signal to the gate driver circuit to disconnect the MOSFET arrays on the (negative) charge and discharge paths. The main circuit designs are extracted from Doc. 9.1 and are shown in Figures 2 to 4.

Cell Temperature Protection Function: BMS monitors the cell temperature through NTCs and the sampled data are transmitted to the MCU through AFE with SPI communication. If the maximum cell temperature is higher than the threshold or the minimum cell temperature is lower than the threshold, the MCU transmits the control signal to disconnect the charge and/or discharge MOSFETs. The main circuit designs of Cell Temperature Protection Function extracted from Doc. 9.1 and are shown in Figure 5 and Figures 2 to 4.

Over Current Protection Function: Stack current is sampled through the Rsense RS201, RS202 and RS203 by measuring the cross volrage. And the sampled current information is transmitted to the MCU by AFE. If the sampled current value exceeds the thresholds, the MCU transmits the control signal to disconnect the charge and/or discharge MOSFETs. The main circuit designs of Current Protection Function extracted from Doc. 9.1 are shown in Figure 6, also referred to in Figures 2 to 4. Figure 6. Current sampling circuitry and AFE Page 9 Atttachment 5 - Functional Safety Report CSA Report No. 305501-80245567 MASTER CONTRACT:305501 REPORT: 80245569 PROJEC: 80245569 Page No: 10 Date Issued: July 17, 2025 FSR-131, V7 Oct 2023 4. Permanent Failures Protection (secondary protection): In the situations of severe failures, which could make BMS unable to cutoff the MOSFETs, Permanent Failures Protection is triggered. Battery protection ICs U102 to U104 monitor the cell voltages and provide secondary protection by actively open the five active fuses (Self Control Protector) FM201 to FM205. When failure of MOSFET is detected by MCU, MCU send <PF FUSE> signal to Q105, then trigger Q161, Q106 and Q104 to pull up the center tap of the internal heaters to the positive rail. The main circuit of Secondary Protection Function extracted from Doc. 9.1 are shown in Figures 7 & 8. Figure 7.
