Battery Performance Development, Modeling & Simulation

Ansys battery simulations help you advance battery designs for all future electronic products. Whether designing a battery for electric transportation or consumer products, the companies who best balance safety, performance, size, cost and reliability will be the market leaders. Accurate battery simulation drives collaboration between supply chain and battery OEMs on important choices in cell chemistry, cooling systems, mechanical protection and battery management systems.

Each of these design choices involve complex tradeoffs with one or more safety or performance metrics and are likely to have regulatory and compliance implications. Ansys battery simulation solutions allow engineers to rapidly evaluate these tradeoffs while minimizing reliance on arbitrary design rules and expensive physical trial-and-error testing. 

Energy storage systems include mechanical, thermal, electrical and battery management subsystems, each with its own requirements and specifications. For example:

  • Mechanical subsystem requirements include crash integrity, mechanical abuse tolerance and environmental durability.
  • Thermal performance requirements dictate that cell-to-cell temperature variations be minimized in a battery pack to optimize capacity and minimize battery degradation. Likewise, for safety reasons, several industry standards require thermal propagation tests to evaluate cell-to-cell propagation resistance, following a single cell triggers into thermal runaway.
  • The electrical subsystem needs to meet peak power and energy demands from different drive cycle environments at different temperatures.
  • Battery management subsystems perform critical operational and safety functions and have functional safety and other requirements that are set forth in standards. 

These requirements are addressed with Ansys multiphysics battery simulation, which brings together interdisciplinary expertise (electrical, thermal, structural, controls) at different scales, including electrochemistry to electrode, cell, module, pack and system and the coupling of different physics.
