    Battery Selection Tutorial Course 3/3: Integrating Your Battery Into Your Product – Designing for Worst-Case Scenarios

    The last part in Exponent’s three-part series, this webinar will focus on the finished product from the viewpoint of the battery. How can you best protect your battery within your device? Is your battery going to be user-replaceable? If you’re creating multi-cell packs, how should they be separated from (yet still connected to) each other? Should a thermal event occur, how can you prevent that from cascading through the whole pack? This webinar will help to answer many of those questions, and discuss design questions to help safeguard your battery pack throughout its entire lifecycle.

    This webinar will focus on the following key topics:

    • Creating multi-cell packs
    • Containing thermal runaway events

    Energy Storage RTE Tutorial Course 1/3: What is Round Trip Efficiency (RTE)? Why is it Important? How Much Does it Cost?

    In the first of this three-part webinar series, a definition of RTE will be presented along with simple system equations that are important to its understanding, determination and management. RTE for some popular battery systems i.e. Lead Acid, Lithium Ion, Vanadium Redox and Nickel Zinc will be computed as examples, and their variation with common variables such as rate, capacity variability & SOC swing will be discussed. The costs of Round Trip inefficiency can be significant, and are experienced by customers either in higher energy generating capital costs and/or higher operating expenses. The calculation of these higher costs will be reviewed, and there will be a discussion on the key industry variables that influence them. Different geographic and customer markets will be considered.

    This webinar will focus on the following key topics:

    • The Importance of RTE to battery selection decisions
    • How does RTE impact CAPEX and/or OPEX for energy storage
    • How is RTE defined and how can it be derived – comparison of different systems
    • An introduction to ancillary equipment energy losses

    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
