Overview

  • Researchers at the China Automotive Collision Repair Research and Technology Center demonstrated a prototype that expels an overheating EV battery using small explosive charges.
  • Laboratory clips show the module being ejected in under 10 seconds to an estimated 3–6 meters before it catches fire outside the vehicle.
  • The video spread widely on Weibo and X, with viewers warning that a launched pack could strike people or vehicles or start secondary fires.
  • A Chery iCar 03T appears in the footage, though Chery stated the tests were not connected to the company.
  • No commercialization timeline has been disclosed, and the concept draws questions over safety, liability and rules, with related fire-safety guidance such as Brazil’s CNCGBM charging protocols entering the conversation.
