New Developments in Isothermal Microcalorimetry and ARC® Testing Methods
FREE Webinar – THT is a proud sponsor of this event.
This presentation describes two main types of calorimetric techniques which can be used to carry out performance and safety testing on batteries. These are isothermal calorimetry and adiabatic calorimetry.
THT’s new Micro Battery Calorimeter is presented along with initial data from a prototype unit. This device is focused on high sensitivity measurement which is required for coin and button cell samples which produce only milliwatts of heat during use. This is an example of an isothermal calorimeter system.
The second half of the presentation covers battery testing methods for the ARC® adiabatic calorimeter system. The theoretical background of the test method is described and recommended practice for various types of testing are discussed.
This webinar will focus on the following key topics:
• Principles of isothermal calorimetry for batteries
• Introduction to the Micro Battery Calorimeter and initial data
• Theoretical background to ARC® testing
• Recommended ARC® testing practices

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

BMS Tutorial Course 3/3: Gain More Visibility Into Your Energy Storage System
Long-term ownership and management of an energy storage system requires high visibility into the batteries to enable problem identification and resolution, compare actual vs. predicted degradation curves, and plan for capacity augmentation. Real-time diagnostics and historical battery health data can be utilized to improve system reliability and reduce the total cost of ESS ownership. Join Nuvation Energy CEO Michael Worry for an examination of how battery data analytics can be retrieved from the BMS and utilized to optimize system maintenance and contribute to the long-term viability of the energy storage system.
This webinar will focus on the following key topics:
• Business impacts of low visibility into internal battery operation
• Problems frequently encountered by operators in the field
• “Cell to cloud” remote system diagnosis
• Battery warranty tracking
