    Maximizing Battery Performance and Reliability for Electric Vehicles and Energy Storage

    FREE Webinar – Voltaiq is a proud sponsor of this event.

    As automakers and utilities transition away from non-renewable energy sources, batteries have become essential for efficient energy storage and delivery. Companies are working intensely to deliver higher capacity and more robust batteries to power their products, but ad hoc development processes cannot keep pace with the volume of battery data being generated. In addition, understaffed battery  development teams are unable to leverage their data to accelerate development or improve production and manufacturing.

    In this webinar, we will outline the challenges that the battery industry is facing and how big data analytics can virtually eliminate manual data management and provide powerful capabilities that deliver rapid insights into a battery’s design that dramatically accelerate the development process and results in products with greater performance and reliability.

    This webinar will focus on the following key topics:

    • Recognizing the challenges and bottlenecks in battery development today
    • Automating the battery data collection, data cleaning, and data management process
    • Identifying design issues earlier with predictive analytics
    • Leveraging metadata to understand the impact of materials, processes and test conditions

    Battery Selection Tutorial Course 1/3: Selecting your Cell and Cell Manufacturer(s)

    After designing your product, you need to ensure the battery with which you are operating it will ensure the right performance and lifetime. When deciding this, narrowing down which chemistry (e.g. Li-ion, lithium primary, NiMH, etc.) best fits your product and which form factor are some of the first steps. Choosing a cell design (high-power vs. high-energy, for example) is another step and finally, finding the right cell manufacturer to fabricate your cells and packs. This webinar is the first in a three-part series on designing the right battery for your product. It will cover many of the key differences in chemistries, form factors, and cell designs and other best practices.

    This webinar will focus on the following key topics:

    • Choosing the right chemistry for your application

    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
