BATTERY PACK, METHOD FOR MANUFACTURING BATTERY PACK, AND VEHICLE - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240039108 titled 'BATTERY PACK, METHOD FOR MANUFACTURING BATTERY PACK, AND VEHICLE

Simplified Explanation

The patent application describes a battery pack that includes a battery pack casing, a battery cell, a barrier assembly, and a filling layer. The battery cell is located inside the casing and has an explosion-proof valve on one end. The barrier assembly is installed on the battery cell and creates an exhaust channel between the end face of the cell and the inner surface of the casing. The filling layer is located outside the exhaust channel and fills the gap between the outer surface of the battery cell and the inner surface of the casing. The filling layer is made of an adhesive colloid.

  • The battery pack includes a casing, a battery cell, a barrier assembly, and a filling layer.
  • The battery cell has an explosion-proof valve on one end and is located inside the casing.
  • The barrier assembly is installed on the battery cell and creates an exhaust channel.
  • The filling layer fills the gap between the battery cell and the casing and is made of an adhesive colloid.

Potential applications of this technology:

  • Electric vehicles: The battery pack can be used in electric vehicles to provide a safe and efficient power source.
  • Portable electronics: The technology can be applied to battery packs used in smartphones, laptops, and other portable devices.
  • Renewable energy storage: The battery pack can be used to store energy from renewable sources such as solar or wind power.

Problems solved by this technology:

  • Safety: The explosion-proof valve and barrier assembly help prevent accidents and ensure the safe operation of the battery pack.
  • Efficiency: The filling layer improves the contact between the battery cell and the casing, enhancing the efficiency of the battery pack.
  • Durability: The technology helps protect the battery cell from external factors, increasing its lifespan.

Benefits of this technology:

  • Safety: The explosion-proof valve and barrier assembly provide added safety features to prevent explosions or other accidents.
  • Efficiency: The improved contact between the battery cell and the casing enhances the overall efficiency of the battery pack.
  • Durability: The protection provided by the filling layer helps increase the lifespan of the battery cell, reducing the need for frequent replacements.
