How to design adaptable Li-ion packs for changing EV safety regulations: Getting ahead of thermal runaway

Increasing global adoption of EVs is putting the spotlight on safety features for these next-generation vehicles. There are some inherent risks involved with the use of lithium-ion batteries, as instability in one cell/battery can increase the temperature of the cell and create an explosion and/or fire, causing irreparable damage. Considering the presence of many cells in proximity within an EV battery, an instability in one cell can easily propagate to adjacent cells, causing a cascading event that could result in a massive exothermic event. Automakers and suppliers are on a quest to reduce the frequency of these events to make electric vehicles safer and more adaptable, while several global authorities are also developing safety standards to mitigate the severity of these events.

Join this session at the Charged Virtual Conference on EV Engineering, presented by Saint-Gobain Tape Solutions, where we will review the status of regulations, consider several current material solutions designed to mitigate propagation at the cell and pack level, and discuss what future trends in development are needed to improve the efficacy, suitability and versatility of such material solutions to the dynamic nature of the cell chemistry and pack architecture.

Pressure Equalization in Battery Packs: An Edge Case Analyses

With the rapid commercialization of electric vehicles, the automotive industry is continually evaluating the impact of different load cases and duty cycles on enclosures that need protection. Battery packs, inverters and other enclosures may experience edge cases in their duty cycles that could lead to severe over-pressurization and vacuum conditions if not accounted for appropriately. With properly designed venting solutions, enclosures can be optimized for weight, cost and manufacturability, while keeping the application-specific needs top of mind in the design phase.

In this presentation, Matt Goode, Product Development Engineer at Donaldson Company, will walk through several of these edge cases, and discuss the use of venting solutions.
