End-To-End Cell–Pack–System Solution: Rechargeable Lithium-Ion Battery - White Paper

Industry has become more interested in developing optimal energy storage systems as a result of increasing gasoline prices and environmental concerns. A major application for energy storage use is hybrid electric vehicles (HEVs) and electric vehicles (EVs). The rechargeable energy storage system is a key design issue, as it dominates overall vehicle performance. The system as a whole must deliver high performance in terms of energy density and power management throughout a variety of driving profiles. The batteries are key elements in sustaining power and energy requirements of the system. However, in many applications the required power and thermal management are key factors for battery sizing. Thermal stability, charge capabilities, lifecycle and cost are also important considerations during the system design process. ANSYS helps engineers deliver hybrid electric vehicle innovation through end-to-end cell–pack–system simulation that includes multiple physics (electrochemistry, electrical, electronics, thermal, fluidic) and controls (embedded software). A simulation-based approach enables designers to achieve shorter design cycles and optimize battery performance, safety and lifespan.
