Description

Technology Field

Background Technology

[0003] With the depletion of petroleum resources and the increasing demand for sustainable energy development, research and development on various alternative energy sources are underway. For example, research on eco-friendly energies such as wind energy, solar photovoltaic energy, solar thermal energy, and bioenergy is actively being conducted, and research on rechargeable batteries is also very active.

[0004] In particular, as the battery industry grows, the technologies applicable to batteries are becoming increasingly diverse and sophisticated. Consequently, research is being conducted on various aspects of batteries, including durability, efficiency, safety, and manufacturing processes.

[0005] Since batteries undergo repeated charging and discharging, and gas may be generated inside the battery cells during use, potentially leading to ignition, safety measures are required to prevent potential fires or thermal runaway caused by these phenomena.

[0006] However, conventionally, research has focused on protection functions in battery management systems that cut off power by measuring overcharging, overcurrent, and overheating of the battery and cutting off the current or notifying an upper system when the limit is exceeded, and there is still a demand for safety measures that can immediately respond to gas generation and ignition caused by chemical reactions in battery cells.
