EV Fires Hit Downtown Apartments: Causes and Countermeasures for Spreading Battery Phobia

In the wake of a recent large-scale electric vehicle (EV) fire in a downtown apartment underground parking lot, a so-called 'battery phobia' is rapidly spreading among consumers. Concerns over EV safety are mounting due to chain explosions and the difficulty of extinguishing such fires, creating a ripple effect across the real estate and used car markets.

The Core of EV Fires: 'Thermal Runaway'

EV fires are particularly dangerous because of the thermal runaway phenomenon that occurs inside the battery cells. Due to internal cell defects, physical impact, or overcharging, the temperature can instantly spike to over 1,000℃, causing the fire to spread sequentially to neighboring cells. Furthermore, because the battery pack is sealed off from the outside, conventional extinguishing agents struggle to penetrate, meaning that putting out the fire requires an enormous amount of time and manpower.

The market points to battery manufacturing defects and Battery Management System (BMS) errors as primary causes. Consequently, domestic and international automakers are putting everything on the line to prove safety, while stocks in the battery value chain are experiencing short-term volatility.

Government and Industry Responses and Outlook

The government has stepped in to allay consumer anxiety by revamping regulations to make the disclosure of EV battery manufacturer information mandatory and accelerating the introduction of a battery certification system. In addition, it is pushing to significantly strengthen standards for firefighting equipment, such as sprinklers in underground parking lots, to block the spread of fires in their early stages.

Industry experts predict, "While the EV fire incidence rate itself is not overwhelmingly higher than that of internal combustion engine vehicles, the issue is the massive scale of damage when a fire does occur," adding that "highly advanced BMS technology and the commercialization of solid-state batteries will be the fundamental solutions."

FAQ: Frequently Asked Questions About EV Fires

• Q. What can EV owners do to prevent battery fires?
  A. It is recommended to keep routine battery charge levels at around 80-90% and to immediately get the underbody battery pack inspected at an official service center if there has been any strong physical impact.
• Q. Do EV fires only occur when fully charged to 100%?
  A. No. Experts generally agree that unless there is a manufacturing defect or internal separator damage within the battery itself, there is a low direct correlation between the charge level and the occurrence of a fire.
• Q. Will EV parking in apartment underground lots be banned in the future?
  A. Rather than a total underground entry ban, the government is updating safety regulations to mandate enhanced firefighting equipment, such as fireproof walls and special sprinklers, in designated EV parking areas.
