Avoid Battery Explosions and Fires – With Right Data and Better Designs
Modern Li Ion batteries contain hazardous chemicals and heat up during use – this combination always has the potential to cause fires and explosions. This presentation will focus on improving the understanding of how such incidents occur, what can be done to avoid them and how the risk can be minimized during early stage design.
The solution lies in knowledge of the heat generation rate during normal use, and information about safe boundaries such as temperature, discharge rate & overcharge in realistic situations that represent actual conditions of use. Data from commercial batteries of different types, including videos of batteries undergoing thermal runaway, will be used to illustrate these points.
A relatively new technique will also be discussed with data, which allows total heat output during discharge to be measured on-line and this can be used both for design and battery modelling. Examples of the data will be provided.
This webinar will focus on the following key topics:
• Why battery fires and explosions occur
• How to design safer batteries through understanding of heat generation
• Video evidence of batteries under explosive conditions
• How better thermal management systems can be designed – based on heat measurement from isothermal calorimetry
• Laboratory instruments suitable for testing and data generation

Finding Your Place as the Industry Doubles Down on Electrified Vehicles
Sales are moving forward, primarily due to the Tesla Model 3. A raft of new vehicles is arriving in 2019. Besides the plug-ins and battery electrics, hybrids (including 48V and stop/start micro hybrids) are coming.
Is it a response to regulatory policy? Yes. Is regulatory policy unclear? Yes. Are some companies leaders and others laggards? Yes. Is the supply base critical to product development? Yes. Automakers are setting their own positions as they try to understand the threats and opportunities in their key global markets, even as the regulatory situation becomes more muddled.
This webinar will focus on the following key topics:
• Current Sales Trends Regarding EVs and Hybrids
• EPA/NHTSA vs. The Automakers!?
• California, EU, and China March Forward
• Strategies in Near-, Medium-, and Long-Term for Supplier and Automaker

Advanced Techniques For Addressing Issues in Battery Safety and Performance Using Adiabatic Calorimetry
FREE Webinar – THT is a proud sponsor of this event.
Adiabatic calorimetry is a widely utilized technique within the field of battery safety research. The method has been adapted from the chemical industry to address a significant range of safety and performance tests on battery components, cells and even modules.
Although a number of different battery tests may be employed using the ARC, interpretation of results is not always straightforward. Some of the principles which apply to ARC chemical testing do not translate directly to battery testing due to the variable nature of samples.
This presentation describes both the advantages and limitations of ARC testing on batteries and how the ARC test can be adapted to address different questions in battery research as well as quality control.
This webinar will focus on the following key topics:
• The principles of adiabatic calorimetry (ARC)
• How calorimetry can be used in battery testing
• What we learn from battery testing by calorimetry
• Pressure measurement and gas collection during thermal runaway
• Advanced testing techniques in adiabatic battery calorimetry

Adding Intelligent Battery Management to Lead-Acid Energy Storage Systems
Lead batteries are resilient and have a low likelihood of catastrophic failure. However, their lifespan can be significantly reduced when operated outside of manufacturer specifications. The extension of lead battery life through active battery management is becoming a compelling value proposition for vendors of lead-based energy storage systems.
The evolving regulatory environment governing energy storage safety is also impacting how both lead and lithium chemistries are to be managed moving forward. Join Nuvation CEO Michael Worry to explore the reasons why active battery management is becoming adopted in large-scale lead battery applications, and how the changing regulatory environment is impacting lead-based energy storage.
This webinar will focus on the following key topics:
• Controlling off-gassing in vented and VRLA lead batteries
• Emerging functional safety regulations and UL 1973
• Using a BMS to reduce the levelized cost of energy
• Automating stack connection sequencing in a multi-stack ESS
• Lead-based energy storage system deployments
