BATTERY PACK HAVING IMPROVED SAFETY - A simplified explanation of the abstract

This abstract first appeared for US patent application 18276144 titled 'BATTERY PACK HAVING IMPROVED SAFETY

Simplified Explanation

The patent application describes a battery pack with a fire extinguishing system for effective control and maintenance of thermal events.

  • Battery pack includes:
    • Battery module with one or more battery cells
    • Fire extinguishing tank holding fire extinguishing liquid, placed on top of the battery module with a through hole
    • Cover member in the through hole of the fire extinguishing tank, opening or closing based on internal pressure changes

Potential Applications

The technology could be applied in electric vehicles, energy storage systems, and other devices using battery packs to enhance safety and prevent thermal incidents.

Problems Solved

1. Mitigates the risk of thermal runaway in battery packs. 2. Provides a proactive fire extinguishing system for enhanced safety.

Benefits

1. Improved safety and reliability of battery packs. 2. Early detection and suppression of thermal events. 3. Prevents potential damage to surrounding equipment or structures.

Potential Commercial Applications

Enhancing the safety features of electric vehicles and energy storage systems with advanced fire extinguishing capabilities.

Possible Prior Art

There are existing fire suppression systems for battery packs, but the specific design of a fire extinguishing tank with a cover member based on internal pressure changes may be a novel feature in this patent application.

Unanswered Questions

How does the cover member detect changes in internal pressure of the fire extinguishing tank?

The patent application does not provide details on the specific mechanism or sensor used to detect internal pressure changes in the fire extinguishing tank.

What is the expected maintenance or replacement schedule for the fire extinguishing liquid in the tank?

The patent application does not address the frequency or process for refilling or replacing the fire extinguishing liquid in the tank.


Original Abstract Submitted

A battery pack is advantageous for effective control and maintenance of thermal events. A battery pack according to one aspect of the present disclosure may include a battery module having one or more battery cells; a fire extinguishing tank holding a fire extinguishing liquid, disposed on top of the battery module and having a through hole formed therein; and a cover member installed in the through hole of the fire extinguishing tank and configured to open or close the through hole according to a change in internal pressure of the fire extinguishing tank.
