FIRE EXTINGUISHING SYSTEM FOR BATTERY OF VEHICLE - A simplified explanation of the abstract

This abstract first appeared for US patent application 17971104 titled 'FIRE EXTINGUISHING SYSTEM FOR BATTERY OF VEHICLE

Simplified Explanation

The patent application describes a fire extinguishing system for battery packs. Here are the key points:

  • The system includes a gas discharger that releases gas from the battery pack during a fire.
  • The gas flows through a gas channel designed to direct it towards the extinguishing agent tank.
  • The extinguishing agent tank contains a fire suppressant.
  • A heat exchange channel is connected to the gas channel and allows the gas to exchange heat with the extinguishing agent in the tank.
  • A nozzle is attached to the battery pack and connected to the extinguishing agent tank through a supply channel.
  • The nozzle supplies the extinguishing agent from the tank into the battery pack.

Potential applications of this technology:

  • This fire extinguishing system can be used in battery packs for various applications, such as electric vehicles, portable electronic devices, and energy storage systems.
  • It can provide an additional layer of safety by quickly suppressing fires that may occur in battery packs.

Problems solved by this technology:

  • Battery packs, especially those using lithium-ion batteries, can be prone to thermal runaway and fires.
  • This system helps to mitigate the risk of fires by providing a quick and effective fire suppression mechanism.

Benefits of this technology:

  • The system can rapidly suppress fires in battery packs, reducing the potential for damage and injuries.
  • By using a heat exchange channel, the system can efficiently cool down the gas and extinguishing agent, enhancing the effectiveness of fire suppression.
  • The integration of the gas discharger, gas channel, extinguishing agent tank, and nozzle provides a comprehensive fire extinguishing solution for battery packs.


Original Abstract Submitted

A fire extinguishing system includes a gas discharger provided at a battery pack and configured to discharge gas in the battery pack, a gas channel configured so that the gas produced from the battery pack and discharged through the gas discharger flows through the gas channel when a fire occurs, an extinguishing agent tank in which an extinguishing agent is kept, a heat exchange channel provided in the extinguishing agent tank, connected to the gas channel so that the gas supplied through the gas channel flows through the heat exchange channel, and facilitating heat exchange between the gas flowing through the heat exchange channel and the extinguishing agent kept in the extinguishing agent tank, and a nozzle provided at the battery pack, connected to the extinguishing agent tank through an extinguishing agent supply channel, and supplying the extinguishing agent, which is supplied from the extinguishing agent tank, into the battery pack.
