    Battery Safety Analytics

    Despite their unrivaled performance and longevity, Lithium Ion batteries (LIBs) are also increasingly recognized as a safety hazard, especially in large scale energy storage installations. Although high-voltage battery packs and modules can be subject to numerous failure modes which are not present at the single cell scale, safety testing on full-scale battery packs can be prohibitively expensive and highly destructive to perform. In this talk, we demonstrate the importance of combining safety testing at the material, cell, and module scales to enhance the design of cells and packs which may mitigate the potential for catastrophe. Strategies to minimize full-scale testing requirements through a combination of carefully designed single cell tests and physics-based modeling are explored.

    This webinar will focus on the following key topics:

    • Bridging the gaps between safety concerns at single cell and module levels
    • Experimental characterization of li-ion cells under abusive conditions
    • Use of reference electrode instrumentation for degradation mode characterization
    • Selection of safe battery materials to enhance cell and module level safety
    • Role of modeling in ensuring safe battery design

    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 2/3: Battery Warranty Tracking for Stationary Energy Storage

    In the energy storage industry, battery warranties are based on the combination of a utilization profile and the responsible management of batteries within specified tolerances. Nuvation Energy CEO Michael Worry will explore how energy storage system providers and users can track battery utilization to ensure adherence to warranty parameters, and to proactively identify and resolve performance deviations that can negatively impact warranty claim outcomes.

    This webinar will focus on the following key topics:

    • Creating the use-case specific battery warranty
    • Energy storage system design for battery life and cycle count targets
    • Battery warranty tracking technologies
    • Data capture vs. compliance reporting

    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
