The low frequency and high risk of electric vehicle fires When discussing electric vehicles, a common question arises: "Are EVs truly safe?" This is one of the primary concerns consumers have when choosing an EV, alongside price, performance, and design. Recent EV fire incidents in India and South Africa have brought these concerns into sharper focus. In India, a residential fire linked to an EV resulted in a tragic loss of 8 lives, while in South Africa, a Volvo EX30 was completely destroyed by fire, drawing significant attention. Although EV fires are not frequent, the reality that their lethality cannot be overlooked is becoming increasingly apparent. According to a recent report by Moonstone Information Refinery, titled 'EV Fire Risk: Low Probability, High Impact – and Increasing Relevance for Insurers,' the incidence rate of electric vehicle (EV) fires is approximately 0.0012%, significantly lower than that of internal combustion engine (ICE) vehicles, which stands at 0.1%. Statistically, EVs appear to be more than 80 times safer than ICE vehicles. However, low frequency does not equate to absolute safety. The report emphasizes that the characteristics of EV fires are fundamentally different from those of ICE vehicle fires. The most significant feature of EV fires is the phenomenon of thermal runaway, which originates within the battery. This is a chain reaction that begins when a single battery cell overheats, causing adjacent cells to successively overheat and generate intense heat. The Moonstone report explains that during this process, the battery itself releases oxygen, sustaining the combustion. This implies that traditional firefighting methods, which aim to cut off external oxygen supply, are not effective. Consequently, EV fires are much hotter, last longer, and are extremely difficult to extinguish compared to ICE vehicle fires. These characteristics pose unprecedented challenges for the insurance industry. According to the report, EV fires mean higher loss severity, increased property damage, and a much more complex claims environment for insurers. The scale of damage per fire incident is substantial, requiring significant time and resources for suppression, and the scope of secondary damage is also extensive. Particularly, if a fire occurs in a parking lot or residential area, the risk of it spreading to adjacent vehicles or buildings is high, which can exponentially increase insurers' liability. Further complicating the issue are risks associated with charging infrastructure. The Moonstone report points out that the situation becomes far more complex if a fire originates from or spreads through charging infrastructure. Faulty installation of charging infrastructure, equipment malfunctions, and inconsistent safety standards can lead to additional fire and liability exposures. In the event of a fire at a charging station, it can be extremely difficult to determine whether the responsibility lies with the vehicle manufacturer, the charging equipment manufacturer, the installer, or the operator. The report particularly emphasizes that the risk of EV fires partially extends beyond the scope of the vehicle itself. This fundamentally complicates insurance policy design and liability allocation issues. Traditional auto insurance primarily considered vehicle defects or driver negligence as key risk factors. However, with EVs, multiple entities are involved, including battery manufacturers, vehicle manufacturers, charging infrastructure providers, and power suppliers, making it very difficult to clearly assign liability in the event of an accident. This poses a significant challenge for insurers in designing new insurance products and setting premiums. New Challenges Faced by Insurers and Consumers Another issue is the difficulty in detecting potential battery defects in advance. The report explains that microscopic damage or manufacturing defects within the battery are often undetectable externally, which can lead to thermal runaway over time. It is particularly challenging to accurately assess battery damage in accident-involved or flood-damaged vehicles. This is a major concern in the used EV market and creates additional difficulties for insurers in assessing risk. Moonstone Information Refinery's research emphasizes that the risk of EV fires should not be evaluated solely based on statistical frequency. This is because, while the probability of occurrence may be low, once an EV fire happens, its severity and the complexity of its management are on a completely different level compared to conventional vehicle fires. Therefore, insurers urgently need to develop new insurance products and response strategies. This means not merely increasing premiums, but understanding the nature of the risk and designing appropriate coverage and exclusion clauses. Separate from the insurance industry's response, EV manufacturers are also making significant efforts to enhance battery safety. This includes the soph
