MANUFACTURING DEVICE FOR ASSEMBLED BATTERY - A simplified explanation of the abstract

This abstract first appeared for US patent application 18200258 titled 'MANUFACTURING DEVICE FOR ASSEMBLED BATTERY

Simplified Explanation

The abstract describes an assembled battery that consists of multiple battery cells stacked in one direction. Each battery cell has a terminal on a surface facing a different direction, and a busbar is welded to the terminal. The manufacturing device includes pressing pieces arranged along the stacking direction, with the tip of each pressing piece facing the respective terminal and the busbar in between. A rotor, engaged with the pressing pieces, is rotated by an actuator and presses the pressing pieces against the busbars. A welder then welds the busbars to the terminals while the rotor applies pressure.

  • The invention is an assembled battery with stacked battery cells and welded busbars.
  • The manufacturing device includes pressing pieces, a rotor, and a welder.
  • The pressing pieces are arranged along the stacking direction and have tips facing the terminals and busbars.
  • The rotor, when rotated, presses the pressing pieces against the busbars.
  • The welder then welds the busbars to the terminals while the rotor applies pressure.

Potential Applications:

  • Electric vehicles: The technology can be used in the batteries of electric vehicles, providing a more efficient and reliable power source.
  • Renewable energy storage: The assembled battery can be utilized in renewable energy storage systems, allowing for efficient energy storage and utilization.
  • Portable electronics: The innovation can be applied in the batteries of portable electronic devices, enhancing their performance and longevity.

Problems Solved:

  • Improved battery assembly: The invention simplifies the process of assembling batteries by automating the pressing and welding of busbars.
  • Enhanced battery performance: By ensuring secure connections between the busbars and terminals, the technology improves the overall performance and reliability of the battery.

Benefits:

  • Increased efficiency: The automated pressing and welding process reduces the time and effort required for battery assembly, increasing overall efficiency.
  • Improved reliability: The secure connections between the busbars and terminals enhance the reliability and stability of the battery.
  • Cost-effective: The automated manufacturing device streamlines the production process, potentially reducing manufacturing costs.


Original Abstract Submitted

An assembled battery includes a plurality of battery cells stacked in a first direction, each battery cell including a terminal on a surface facing a second direction that intersects the first direction, and a busbar being welded to the terminal. A manufacturing device includes: a plurality of pressing pieces arranged along the first direction, a tip of each of the pressing pieces in the second direction facing the respective terminal with the busbar interposed between the pressing piece and the terminal; a rotor that extends along the first direction and that is rotated by an actuator, the rotor being engaged with the pressing pieces and being configured to press the pressing pieces against the busbars when rotated about an axis; and a welder that welds the busbars and the terminals. The welder welds the busbars to the terminals while the rotor presses the busbars against the terminals.
