The testing laboratory was provided by ESRG (Energy Service Response Group), also ISO 17025 accredited. Testing was conducted in November 2022 in accordance with ANSI/CAN/UL 9540A:2019 Fourth Edition, Dated November 12, 2019 - Test Method for Evaluating Thermal Runaway Fire Propagation in Battery Energy Storage Systems. This supplemental guide is intended to aid Authorities Having Jurisdiction (AHJs) in the application of the test results to determine compliance with applicable codes. Specifically, it is intended for use where building and/or fire codes require large-scale fire test data to support deviations from the minimum requirements set forth in those codes. The Tesla Powerwall 3 has met the unit level performance criteria outlined in ANSI/CAN/UL 9540A when installed as follows: • The Powerwall must be installed in accordance with the manufacturer's installation instructions • No additional non-combustible substrate is required • Where applicable, a minimum clearance of 1" on the side(s) of the unit is required to mitigate the risk of side-to-side propagation to adjacent Powerwall 3 units and walls • The Powerwall 3 manufacturer installation instructions require a minimum lateral separation of 4" between units Page and Section numbers referenced from the test report are presented in bold type. For example, verification that the Tesla Powerwall 3 has met the performance criteria outlined in ANSI/CAN/UL 9540A can be found on pages 17 through 20 of the report. For ease of use, this guide is arranged to follow the sequence used in the report issued by Intertek titled Test Report ANS1/CAN/UL 9540A:2019. The scope of the report includes the performance criteria outlined in Section 9 - Unit Level Testing of ANSI/CAN/UL 9540A: 2019 Fourth Edition. The report also includes a summary of data acquired at the cell and module levels during prior testing.

This section provides important information needed to determine residential and fire code compliance where reduced minimum separation distances are permitted, and where the unit is intended to be installed on a combustible substrate. Final verification that the Tesla Powerwall 3 has met the performance criteria outlined in ANSI/CAN/UL 9540A can be found on pages 17 through 20 of the report. This portion of the 'report can be used as a checklist to aid in the verification of the unit's conformance to the performance criteria for the intended installation configurations. Table 9.1 from the test report is divided into two parts, residential and non- residential installations. It is important to note that Tesla Powerwall 3 was only evaluated for residential installations under the scope of this testing. In the unit level test, it was demonstrated that: • The Powerwall 3 enclosure provides adequate thermal protection from the wall surface on which it is mounted. Wall surface temperatures did not exceed 97°C (175°F) of temperature rise above ambient per 9.2.15 of the test standard; as such, additional substrate is not required • Thermal runaway did not propagate past (1) target cell • Large scale fire testing was conducted with 1" lateral unit spacing to represent worst-case scenario conditions. Testing showed the risk of unit-to-unit propagation to adjacent units is mitigated with 1" unit spacing • Manufacturer installation instructions dictate 4" minimum lateral spacing between units to',maintain proper airflow during normal operation. Figure 1: Photo 2 from Test Report Displaying Test Set Up 2023 Powerwall 3 ANSI/CAN/UL 9540A:2019 Fourth Edition Test Report Supplemental Guide 4 Cell Level Construction General product details, including cell and module level construction and Tests information, are outlined on pages 5 and 6 of the test report. Pages 5 and 37 of the report provide background information and data collected during cell and module-level testing previously conducted. This data does not directly correlate to residential or fire code requirements; rather, it is used to document and compare the characteristics of different cell chemistries and module designs. One important value recorded is the temperature at which thermal runaway occurs. This value is determined in accordance with 7.3.1.9 of the test standard. This temperature of 1880C is used to verify that an internal fire condition has been established during the Unit Level test. Construction Details: Cell Level Powerwall 3 utilizes Lithium Iron Phosphate/Graphite chemistry based prismatic cells. Cell dimensions, weight and electrical characteristics are noted on page 5 of the test report. Figure 2: Photo 1 from Test Report Displaying an Individual Cell Performance Criteria: Cell Level Application of heat using film heater methodology did result in a thermal runaway condition; therefore, module level testing was required (page 37 of the test report) Cell surface temperature at venting: 1740C Cell surface temperature at runaway: 1880C 2023 Powerwall 3 ANSI/CAN/UL 9540A:2019 Fourth Edition Test Report Supplemental Guide 5 Module Level Construction and Tests Construction Details: Powerwall 3 consists of a single module with, cells positioned within Module Level a metallic semi-open enclosure. The Powerwall 3 module is designed without a fully encapsulated metallic enclosure to allow vent gases to be routed in such a way that increases the overall propagation resistance of the module; this prevents a dangerous buildup of gases that could lead to an explosion or deflagration hazard. The module consists of 26 cells electrically wired in series and arranged in two rows of (13) prismatic cells; this information can be found on page 5 of the test report. Figure 3: Illustration 2 from Test Report Depicting the Layout of Cells in the Module Performance Criteria: Application of heat using film heater methodology did result in Module Level a thermal runaway condition, and the resulting event was not contained by the module design; therefore, unit level testing was required. 2023 Powerwall 3 ANSI/CAN/UL 9540A:2019 Fourth Edition rest Report Supplemental Guide 6 Unit Level Test: General Section 9: Unit Level Testing information begins on page 7 of the report. In additional to providing greater detail on the test setup and unit performance, this portion of the report can also be used as a checklist to aid in the verification of the testing/aboratorv's conformance to the test procedure. Sample and Test Configuration ANSI/CAN/UL 9540A provides for several configurations: • Residential and non-residential use cases • Wall and floor mounting • Indoor and outdoor locations Tested Configuration Testing was conducted using a single indoor wall-mounted test configuration that was determined to be representative of all intended installation configurations.Tesla Powerwall 3 is intended to be installed in any of the configurations noted below (Section 9.1.1 of the test report): • Indoor floor-mounted residential use BESS • Outdoor ground-mounted residential use BESS • Outdoor wall-mounted residential use BESS • Indoor wall-mounted residential use BESS The testing configuration was adapted to include the characteristics necessary to be an accurate representative test case for the above listed scenarios. This determination was made by the testing laboratory based on allowable installation scenarios for Powerwall 3 in conjunction with rigorous pre-test planning, component level review of the BESS unit construction, integral thermal runaway mitigating factors, and cell level chemistry. • In accordance with Section 9.1.2 of the test standard, the indoor floor-mounted test is considered representative of the outdoor ground-mounted test with the incorporation of a 1-ft soffit. • Section 9.1.2 of the test standard dictates all testing is to be done indoors with distances between'in itiati ng and target units being representative of the intended installation scenario. • Tesla Powerwall 3 unit to unit spacing is agnostic of the installation configuration. • Worst case representative testing conducted with 1" unit to unit spacing; manufacturer installation instructions dictate 4" minimum unit to unit spacing. 2023 Powerwall 3 ANSI/CAN/UL 9540A:2019 Fourth Edition Test Report Supplemental'Guide 7 Tested Configuration: Testing was conducted in a standard NFPA 286 fire test room, with Unit Level Test the test room being 12 x 8 x 8-ft high with a 2.5 x 7.5-ft high opening. Walls were covered with standard 5/8" gypsum board which was painted black in accordance with Section 9.2.6 of the test standard. y xg Figure 4: Photo 5 from Test Report Figure 5: Photo 3 from Test Displaying Room Used for Testing Report of Test Configuration Units were installed on an instrumented wall with (16) thermocouples running the length of the wall, with 6" spacing between thermocouples.

This application of heat must result in an internal fire condition in accordance with the module level test previously conducted.This was verified by testing staff using temperature data recorded during initiation of the event, compared against the cell surface temperature at thermal runaway during the cell level test. This temperature was determined to be 1880C in accordance with 7.3.1.9 of the test standard - see page 37 of the test report. Thermal Runaway was induced consistent with the methodology determined in the module level test. Internal fire conditions were confirmed using thermocouples placed inside the initiating unit to monitor cell level surface temperatures. Thermal runaway was confirmed in the target and initiation cells with no further propagation to other cells within the module.

Beginning on page 13 of the test report, all required information to Test Results be included in the unit level report is provided in long form. The unit level performance criteria table begins on page 16 of the report, with the applicable performance criteria for residential installations beginning on page 17. Unit level performance criteria indicated in Table 9.1 of the test report provides a basis for the approval of the test report through satisfactory conformance to all required unit level performance characteristics. A summary of key sections of the performance criteria are provided below. Cheesecloth DUT was wrapped in cheesecloth during entirety of test procedure. No flaming or charring was observed outside of the unit, and the cheesecloth indicator was not burned or charred. The cheesecloth is noted "as is after the test" on page 23 of the test report. Cheesecloth is frequently used as a fire indicator in regulatory and safety testing to assess fire hazards during abnormal operations; similarly, the cheesecloth is required by the ANSI/CAN/UL 9540A test standard to ensure an internal fire is contained by the unit level enclosure. 4 1 Figure 10: Photo 6 from the Test Report Displaying "Cheesecloth as is After the Test" 2023 Powerwali 3 ANS!/CAN/UL 9540A:2019 Fourth Edition Test Report Supplemental Guide 11 Unit Level Test: Test Results (cont.)
