Simulation Of Battery Crash – Where Do We Stand?
FREE Webinar – PlugVolt is a proud sponsor of this event.
Safety is an important functional requirement in the development of large-format, energy-dense, lithium-ion (Li-ion) batteries used in electrified vehicles. Computer aided engineering (CAE) tools that predict the response of a Li-ion battery pack to various abusive conditions can provide valuable insight during the design phase and reduce the need for physical testing.
However, the physics under such simulations is quite complex, and involves structural, thermal, electrical and electrochemical behaviors all coupled together and spanning length and time scales of different orders of magnitude.
In this talk, ANSYS LS-DYNA’s capabilities in the area of battery simulation will be introduced, current numerical challenges discussed, as well as a potential way forward towards including battery models in full car crash simulations.
This webinar will focus on the following key topics:
• The state of battery crash simulations
• Numerical challenges
• Capabilities of the commercial finite element code in ANSYS LS-DYNA
• A path towards capturing the thermal/mechanical/electromagnetic behavior of batteries during a full vehicle crash

Measurements That Accelerate Battery Development
FREE Webinar – Metrohm is a proud sponsor of this event.
Material damage and defects in separators and collectors can ultimately cause thermal runaway and lead to failure of the cell. Improved design of these key components is vital for safer batteries, and proper testing early in the development process ensures high performance.
In this webinar, battery expert Brian Morin, CEO of Soteria Battery Innovation Group, will reveal new architectures that lead to safer cell performance. Reza Fathi, Product Specialist from Metrohm Autolab, will discuss the use of electrochemical impedance spectroscopy (EIS) for Li-ion battery analysis. Using case studies and real-world examples, they will also describe why performance-predictive electrical and electrochemical measurements are necessary to accelerate the development process.
This webinar will focus on the following key topics:
• How to design separators and current collectors to deter thermal runaway
• How to utilize bench-top measurements as screening tools during early cell development to reduce time and expense
• How temperature-controlled impedance measurements lead to advanced materials analysis
• Electrochemical techniques to test and evaluate Li-ion cells

Determination of Battery Safety and Performance Parameters Using Adiabatic and Isothermal Calorimetry
FREE Webinar – Thermal Hazard Technology is a proud sponsor of this event.
This presentation describes two main types of calorimetry which can be used to carry out safety and performance testing on batteries. Isothermal calorimeters allow for direct heat measurement on cells during use, while adiabatic calorimeters can measure heat released from batteries during thermal runaway.
Calorimetry can serve as a quantitative scientific method for evaluation of battery safety but it requires appropriate instrumentation. The principles of operation of both types of calorimeters are described along with specific applications within the field of battery testing.
A combination of both technics allows for detailed thermal characterization of lithium-ion and other rechargeable cells, and differences due to chemistry, cell design, cell age, state of charge and cell size can be evaluated.
This webinar will focus on the following key topics:
• The principles of adiabatic and isothermal calorimetry
• How calorimetry can be used in battery testing
• Parameters established by adiabatic safety testing
• Parameters established by isothermal performance testing
• Pressure measurement and gas collection
