  • ANSYS is the answer for batteries

Batteries are the key to every electronic device we now depend upon — especially smartphones and laptops — and they are the weak link in the system.

Walt Mossberg

Batteries are the key driver in the world of portable devices. They are the critical component of our portable gadgets and are becoming increasingly important in our vehicles as well. The company that can engineer and get the most out of their batteries will clearly have a significant competitive advantage over the competition. Batteries, however, are clearly difficult to simulate due to their multiphysical, multiscale nature and how they are used in devices. Only ANSYS, with its portfolio of industry leading software working together is up to the challenge.

Determine relevant performance characteristics of your potential battery cells with fully coupled electrochemical-thermal-flow models. Try out many different electrode designs in silico to get it right early on and avoid expensive prototyping and testing. Confidence in the design early on in the design cycle will allow you to get the most out of your product.

  • Ensure temperature uniformity through fully coupled, multiphysics and multiscale models
  • Heat generation
  • Charge density

Manufacturing defects, physical stress and unanticipated transient phenomena may all lead to unreliable or dangerous situations with a battery. Avoid and mitigate expensive failure modes and unacceptable safety issues.

  • Create detailed mechanical models to simulate the battery under a variety of conditions.
  • Gain insight into charge/discharge behaviour through coupled electro+thermal+circuit models
  • Create detailed electrode and cell models to anticipate and deal with possible manufacturing defects
Durability

A promising new battery design is just the beginning for disruptive new technologies. Long term quality can be assured and designed for by a variety of in silico simulation techniques. Whether a warranty period is 2 or 20 years, company reputations for quality and technological leadership are made here.

  • Simulate system behavior to account for complex interactions
  • Model cyclic behavior to ensure long term performance and customer trust
  • Specialized tools for battery modeling to enable comprehensive simulation
