Researchers have long known that high electric currents can lead to "thermal runaway" – a chain reaction that can cause a battery to overheat, catch fire, and explode.
Lithium-ion battery-powered items, including a robot vacuum, mobile phone, and children's toys, were found among the refuse, suggesting thermal runaway caused the fire. Fortunately, there were no reported injuries. The incident serves as a reminder to dispose of lithium-ion batteries at designated recycling centers to prevent fires.
Sometimes the firefighters may decide to let the battery just burn itself out, rather than dousing it with water. Once an EV battery catches fire, it's possible for the chemical fire to reignite after the initial burn dies down. It's even possible for the battery to go up in flames again days later.
According to the Kent Fire Department incident report, initial attempts to extinguish the fire with water were unsuccessful, as the fire reignited underneath the vehicle after appearing to be extinguished. Then, the firefighters cut a hole to apply water directly to the burning battery.
With thermal runaway, a chemical reaction located in one of the cells lights an initial fire, and the heat soon spreads to each adjacent cell until the entire EV battery is burning. Greg Less, director of the University of Michigan's Battery Lab, breaks down EV battery fires into two, distinct categories: accidents and manufacturing defects.
Lithium-ion batteries, found in many popular consumer products, are under scrutiny again following a massive fire this week in New York City thought to be caused by the battery that powered an electric scooter. At least seven people have been injured in a five-alarm fire in the Bronx which required the attention of 200 firefighters.
Technically: it is the "thermal propagation" properties of the battery pack which may, or may not, prevent it from getting involved in an automotive fire – even if one or more of the cells in the battery pack has overheated dangerously, the upholstery has already caught on fire, or the car's wiring harness is severely damaged.
From January–March 2025 we tracked significant rooftop PV fire incidents worldwide on commercial and agricultural buildings. Each entry lists date, what burned, where, suspected cause when known, and notable consequences like roof damage, smoke, water-damage, or PV debris. A house fire in Kleve, Germany involving integrated photovoltaic roof tiles required about 65 firefighters and lasted nearly five hours, with the blaze mainly confined to the roof and no injuries reported. This AllShield tracker lists each incident with date, location, likely cause and impact, plus verified sources and expert insight—so insurers and owners can benchmark risk and improve safety. We. According to PV Watch, a rooftop fire broke out at the Gotion Energy manufacturing base in Changzhou's Jintan District on the afternoon of July 21, sending thick plumes of smoke into the sky and drawing widespread attention from passing residents and online observers. The fire affected a single-family home and required about 65.

Contrary to popular belief, quality photovoltaic inverters don't automatically shut off during rainfall. 2 inches per hour – far beyond typical storm. While most modern inverters have IP65 ratings (dust-tight and protected against water jets), prolonged exposure to heavy rain can still cause: "Think of inverter protection like a good umbrella – it's not just about surviving a drizzle, but weathering storms. " - Solar Maintenance Expert, NREL. Example: The installation position is in a dip or the installation height fails to meet requirements, it may lead to the inverter or cable port being exposed to water. Solution: Refer to the product manual for installation spacing, the bottom of the conventional installation inverter is≥500mm from. However, outdoor environments expose solar inverters to harsh conditions such as dust, rain, humidity, heat, pollution, and voltage fluctuations. This is where IP65 protection plays a critical role.
