Opinion

UNITED STATES DISTRICT COURT DISTRICT OF MINNESOTA

American Family Insurance Company, No. 21-cv-1749 (KMM/DJF) S.I.,

Plaintiff,

v. ORDER

Pecron, LLC,

Defendant.

In this action, American Family Insurance Company, S.I. alleges that Pecron, LLC designed and manufactured a defective portable battery-powered generator, which caused significant damage to property that American Family insured. Pecron argues that based on the evidentiary record, it is entitled to summary judgment for two overarching reasons. First, Pecron asserts that because no reasonable jury could conclude that it manufactured the generator that allegedly caused the fire. And second, Pecron contends that American Family cannot establish the elements of either a strict liability or a negligence claim. As discussed below, because the Court finds that American Family has failed to present evidence that would allow it to prevail on either its design- or manufacturing-defect claims, Pecron’s motion for summary judgment is granted. BACKGROUND Corey Nihart and Katie Nihart own a home in Fairbault, Minnesota, which they insured through a homeowner’s policy with American Family. In November 2019, the Niharts purchased an Aeiusny 400W Solar Generator Portable Power Station (hereafter “the generator”) from Amazon’s online store. Corey purchased the generator for a fishing trip in the fall of 2019, and he may not have charged or used the generator at any time

after that trip. The generator was stored in a 60’ x 40’ metal clad detached shed near the Nihart’s home. On the morning of January 2, 2021, the Niharts’ son had planned to go ice fishing. The night before the trip, he entered the detached shed and plugged in some equipment for his trip on a plastic table, including the battery inside a Vexilar depth finder, a spare

12V lead acid battery, and the generator. The following morning, around 6:40 a.m., he entered the shed again, but encountered heavy black smoke and the Faribault Fire Department was dispatched to the Nihart property. The Fire Department arrived at 7:00 a.m. and saw that the fire had originated in the northwest corner of the shed, but had burned itself out. Later that day, however, it was discovered that the initial fire had

extended into the building’s attic insulation and created a smoldering fire. Corey saw smoke coming from the eaves of the shed and called the Fire Department a second time. The building and personal property within it was heavily damaged. The Niharts submitted an insurance claim to American Family, and American Family paid for the covered damage. American Family then became the Niharts’

subrogee for any claims relating to the cause of the fire. American Family hired Whitemore Fire Consultants and Senior Fire Consultant, Douglas Noah, to investigate the origin and cause of the fire. Mr. Noah concluded that the “fire originated in the northwest corner of the . . . workshop portion of the building [and that] . . . the cause of th[e] fire was a Aieusny® 400W Solar Generator Portable Power Station that was plugged in and charging.” [Ellingson Decl., Ex. 3, Noah Report at 7.] In reaching those conclusions, Mr. Noah relied, in part, on the laboratory analysis of artifacts recovered from the scene. That analysis was performed by Electrical Engineer, Luke Choudek. Mr. Choudek determined that the remains of the other items that the Niharts’ son had plugged in prior to his fishing trip showed signs only of fire attack. Mr. Choudek also acquired an exemplar Aeiusny generator and compared the battery cells from the exemplar to the artifacts recovered from the subject generator at the scene. That comparison showed that some of the generator’s cells “had ruptured and partially ejected their contents.” ce SN eo! 5 1 ee : ee = Palme seo Bae i amaiiaaal a a (2aoy ie = Sas ences OR | Nae ps eee ile.

[Ellingson Decl., Ex. 1, Choudek Report at 8.] Mr. Choudek noted that on several locations in the exemplar generator, components had been labeled with the name “Pecron.”

Mr. Choudek suggested that the generator contained a design flaw as follows: If the battery charger and pack are not properly equipped with charge and discharge monitoring, a failure within a cell can go undetected. A failure within a cell can result in a thermal runaway scenario which can result in fire.

The three ruptured cells inside the pack are distinctly different in physical appearance. The damage sustained to the pack and individual cells, in a fire attack scenario, should be relatively uniform similar to the damage sustained by [another item that had been plugged in near the generator].

The localized damages sustained within the [generator] suggests a failure of the battery pack and/or charging components resulting in a thermal runaway scenario and fire.

[Id. at 11.] Further, Mr. Choudek consulted a National Fire Protection Association research paper entitled Lithium-Ion Batteries Hazard and Use Assessment. [Id.] The research paper’s introduction noted that use of lithium-ion batteries in portable devices had become widespread, in large part due to their high energy density. However, that density “combined with a flammable organic, rather than aqueous, electrolyte has created a number of new challenges with regard to the design of batteries containing lithium-ion cells. . . .” [Id.] Mr. Choudek noted that, based on its experience, Exponent, the researcher who prepared the paper, cautioned that “for commercial lithium-ion battery packs with mature protection electronics packages, the majority of thermal runaway failure in the field are caused by internal cell faults related to cell manufacturing defects.” [Id. at 11–12.] Ultimately, Mr. Choudek offered several opinions regarding the electrical systems

potentially involved in the fire and their role in causing the damage to the Niharts’ property. [Id. at 12.] First, he opined that the fire originated in the northwest corner of the structure. Second, he concluded that the “only identified source of ignition was the energy released from the failed cells within the [generator].” Third, that a “failure of the cells within the [generator] cannot be eliminated as a cause of the fire.” And finally,

Mr. Choudek ruled out the other electrical items located near the generator as possible causes of the fire. [Id.] The Court has previously described the procedural history of this litigation in detail [see Doc. 115 at 1–4], and that background will only be briefly summarized here. American Family originally brought suit solely against Amazon. Amazon later certified

that Pecron, LLC was the product manufacturer pursuant to Minn. Stat. § 544.41, subd. 1, based on the information Amazon gathered, including its own review of an exemplar Aeiusny generator and documentation Amazon received suggesting a link between Pecron and Aeiusny. American Family amended its complaint, naming Pecron as a defendant and eventually agreed to Amazon’s dismissal. Throughout the litigation,

Pecron has insisted that Amazon should never have certified it as the manufacturer of the generator and American Family should never have added Pecron as a defendant. Pecron maintains that American Family cannot show it is responsible for manufacturing the generator at issue. The parties conducted fairly limited discovery. For example, American Family declined to depose Weixin Shi, Pecron’s sole member, and took no discovery from the Niharts, although they were interviewed by American Family’s expert witness, Mr. Noah.
