    Thermal Runaway Testing and Cause Analysis of an Automotive Li-Ion Cell

    Part 1 focuses on the safety tests with large lithium-ion cells. We explain our test method and equipment to trigger and characterize a thermal runaway (TR). Then we present a case study with a large pouch cell which is brought into TR by over-temperature. We discuss the temperature curves, the voltage/resistance curves, gas releases and gas compositions.

    Part 2 covers composition analysis of large lithium-ion cells to interpret what happened during high temperature test. We also conduct thermal stability analysis of charged electrode to know the temperature when exothermic decomposition and oxygen release from cathode start. From that information, we can obtain key parameters to control thermal runaway from material design point of view.

    This webinar will focus on the following key topics:

    • Methods for safety tests of large lithium-ion cells
    • Thermal runaway of a large pouch cell caused by over-temperature
    • Detailed analysis of the gas, which is released during thermal runaway
    • Composition analysis of large scale lithium-ion cells
    • Thermal stability of charged electrode

    DER Tutorial Course 1/3: Energy Storage and DER Control Behind the Meter

    The implementation of distributed energy resources behind the meter has become increasingly commonplace for commercial, industrial, and even residential energy consumers. While energy security is often a key driver, it is demand charge management that provides the return on the infrastructure investment. DER aggregation and demand charge management technologies however, have not yet fully caught up with the relative maturity of the resources they control. Join John Chinnick, Principal Software Architect at Nuvation Energy for an examination of distributed energy resource management behind the meter, and how to integrate and manage DER assets for demand charge management.

    This webinar will focus on the following key topics:

    • Types and tiers of distributed energy resource management
    • Technical constraints and opportunities in asset management
    • Integrating energy resources for centralized control
    • A demand charge management implementation model

    DER Tutorial Course 3/3: Battery State of Health in Energy Storage Systems

    State of Health (SOH) is a widely used and often misunderstood term within the energy storage industry. What does it mean to say that a battery is at 90% SOH? How does battery SOH impact the performance of an energy storage system used for a particular application? Stefan Janhunen, Principal Software Architect at Nuvation Energy, will explore common industry definitions and misconceptions surrounding State of Health and will take a deeper dive into the fundamental metrics of battery health that impact overall energy storage system performance.

    This webinar will focus on the following key topics:

    • What is State of Health and how is it defined?
    • The most common metrics used to measure battery performance and health
    • The effects of battery degradation on energy storage system performance
    • Moving towards an energy storage system perspective on State of Health
