Assembly System Configurator for Lithium-Ion Battery Manufacturing

Background

  • Lithium-Ion battery technologies are changing rapidly as new cell chemistry and cell types are being developed.
  • Demand for lithium-Ion batteries is highly variable since the electrical vehicle market is still developing.
  • The assembly systems for battery packs much be reconfigurable.

Objective

  • To develop the mathematical tools and software system which serve as a battery assembly system “design aid”.
    • Given cell types and geometry and the pack volume demand, generate assembly system configurations
    • Perform throughput analysis and cost modeling to select best configuration

Approach

  • Develop a system design database of stacking machines
  • Create algorithms to generate automated assembly system alternatives
  • Output such configurations to Witness for performance evaluation
