Why Chinese-made EVs are being banned from parking garages in China

With the growing popularity of electric vehicles (EVs) in China, concerns around EV safety, specifically the risks associated with spontaneous fires, have led to the ban of EVs from some parking garages. Recent reports indicate that certain facilities, particularly underground garages in Zhejiang Province, have restricted access for EVs due to their higher likelihood of thermal runaway incidents, which pose unique challenges in confined spaces.

Rising safety concerns: Fire incidents in EVs and e-bikes

Several incidents involving EVs catching fire have highlighted the potential hazards associated with lithium-ion battery technology. For instance, a fire in August 2024 in Guangzhou saw multiple EVs and electric bikes spontaneously combust, causing significant damage.

This was not an isolated case, as multiple reports throughout the year have documented similar spontaneous ignition incidents with electric vehicles in enclosed spaces. Safety concerns have been exacerbated by challenges in extinguishing EV fires.

Unlike conventional vehicles, lithium-ion battery fires can reignite repeatedly even after initial containment, making them particularly difficult to manage in enclosed spaces like parking garages

Why EV fires are difficult to manage

The primary cause of EV fires is “thermal runaway”, a process where the battery overheats to the point where it combusts uncontrollably. In confined spaces like underground parking, low ceilings often hinder firefighting efforts, and the toxic fumes from burning lithium-ion batteries create additional health hazards.

Traditional fire suppression systems are ineffective in completely extinguishing these fires, as water alone cannot stop the chain reaction within a damaged lithium-ion cell. Additionally, reports of fires raging even after vehicles were pushed into water illustrate the need for specialised techniques to manage these incidents safely.

Policy response: Parking restrictions

In response to these challenges, multiple commercial facilities in regions like Hangzhou have begun implementing parking restrictions for EVs. For instance, certain hotels and office complexes now direct EV drivers to outdoor parking spaces rather than allowing them access to underground garages, citing safety protocols and limited firefighting resources as key reasons.

This trend reflects an increasing caution in China, which has emerged as one of the largest EV markets globally, with millions of electric and hybrid vehicles sold annually.
