KATHMANDU, September 15, 2026 - Electric vehicles are rapidly transforming transport in Nepal and around the world, offering an important pathway to reduce dependence on imported fossil fuels and, where electricity comes from low-carbon sources, cut transport emissions. But a recent fatal electric-vehicle fire in Bharatpur has also raised an important public-safety question: why can an EV catch fire, and how should such incidents be prevented and managed?
The answer begins with the battery.
Most modern electric vehicles use lithium-ion battery packs made up of thousands of interconnected cells. Under abnormal conditions, a cell can experience thermal runaway-an uncontrolled chemical reaction in which heat is generated faster than it can be dissipated. Heat from one failing cell can spread to neighbouring cells, potentially causing thermal propagation, intense heat, flammable-gas release, smoke and fire.
Thermal runaway can have several possible triggers. These include an internal manufacturing defect or short circuit, severe physical damage to the battery following a collision, electrical faults, overheating, or problems associated with charging equipment. Battery-management systems and thermal-management systems are designed to detect and control abnormal conditions, but no technology eliminates risk entirely.
Nepal's Bharatpur case highlights the need for evidence, not speculation
The death of a 55-year-old man after his electric car caught fire while travelling on the East-West Highway near Bharatpur has understandably generated concern in Nepal. However, investigators have not yet established that the battery caused the fire.
Nepal's recent experience shows why this distinction matters. A 2024 MG EV fire in Budhanilkantha was attributed after technical investigation to a short circuit involving the charging cable and socket, while the vehicle's high-voltage battery remained undamaged. In a 2025 BYD Atto 3 fire in Morang, technical inspections reportedly found the battery and high-voltage powertrain intact, with external combustible material identified as the probable source.
The Bharatpur investigation therefore needs to establish whether the origin was the traction battery, charging system, collision or another electrical or mechanical failure before conclusions are drawn.
EV fires are different-not necessarily more common
It is important not to confuse fire severity with fire frequency.
Available evidence does not support the simplistic claim that electric vehicles are inherently more likely to catch fire than petrol or diesel vehicles. Norway's Directorate for Civil Protection and Emergency Planning, for example, says research has found no basis for claiming that EVs present a greater fire danger than fossil-fuel vehicles; rather, EV fires can behave differently.
The particular challenge is the battery's stored chemical energy. Once thermal runaway begins, a damaged lithium-ion battery can continue producing heat and flammable gases, and reignition can remain a concern. US safety authorities therefore treat damaged or flooded EVs as a special emergency-response issue.
A lesson for Nepal's rapidly expanding EV market
Nepal's geography makes battery safety especially important. Vehicles regularly travel through steep mountain roads, rough terrain and flood-prone corridors. Recent monsoon disasters have also demonstrated how vehicles can be exposed to deep water, debris and severe impacts.
A flood-damaged EV should not simply be restarted or parked inside a home or enclosed garage. US vehicle-safety guidance warns that water-damaged high-voltage batteries can present shock and fire hazards, including the possibility of delayed fire.
Nepal therefore needs stronger systems for EV safety: independent battery and vehicle testing, transparent recall mechanisms, qualified charging infrastructure, trained technicians and firefighters, emergency-response protocols, post-crash battery inspections and reliable national data on EV-related incidents.
Charging infrastructure also deserves particular attention. Safe charging requires properly installed equipment, undamaged cables and connectors, appropriate electrical protection and compliance with manufacturer recommendations.
Safety must strengthen-not undermine-the clean-energy transition
The lesson from EV fires should not be that Nepal should abandon electric mobility. It should be that clean transportation must also be safe transportation.
Nepal has a strategic opportunity to build an electric-mobility system around its abundant renewable electricity while learning from international experience. But public confidence will depend on transparent investigations whenever an EV fire occurs, accurate statistics, stronger regulation and professional emergency response.
The future of electric mobility should not be a choice between climate action and safety. Nepal can-and must-deliver both.
