  • (FREE) NUVATION ENERGY: Course 2 of 3 – Battery Stack Design for UL 1973 Certification

    Thursday, August 13, 2020 | 01:00 P.M. EDT USA

    If you are developing a stationary energy storage system, chances are you have already heard of UL 1973 and UL 9540. Being certified to these important safety standards is quickly becoming the price of admission in the energy storage industry. When taking your battery stack design through the UL 1973 certification process, the level of effort is significantly impacted by the compliances and ratings of the individual components in your battery rack. Join Nate Wennyk, Senior Hardware Designer at Nuvation Energy, for an inside look at the development of UL 1973 Recognized battery stack solutions.

    This webinar will focus on the following key topics:

    • Understanding battery stack architecture
    • Impacts of component certifications on the UL 1973 LOE
    • Designing flexibility into a locked-down stack configuration
    • UL 1973 Recognition case studies and engineering war stories

    A PDF copy of the presentation will be sent to all attendees after the event.

  • WPI: Experimental Investigation of Cascading Failure in Lithium Ion Cell Arrays – Impact of Cathode Chemistry

    Wednesday, September 02, 2020 | 10:00 A.M. EDT USA

    In lithium ion arrays, thermal runaway may propagate from a failing cell to neighboring cells and grow into a large-scale fire in a phenomenon referred to as cascading failure. A new experimental setup was developed to investigate cascading failure using 12 cell arrays constructed from cells of 18650 form factor. Thermal runaway was initiated in one cell using an electric heater and observed to propagate through the array using temperature sensors. Cascading failure was studied in nitrogen or air environment to elucidate the impact of combustion. The cell temperature allowed calculation of row-to-row propagation speed in arrays of different cathode chemistries. The yields of oxygen, carbon monoxide, carbon dioxide, total hydrocarbons and hydrogen were measured; corresponding fire hazards were assessed.

    This webinar will focus on the following key topics:

    • Thermal runaway propagation
    • Thermal runaway hazards
    • Failure dynamics
    • Flammability and toxicity
    • Failure Mitigation and suppression

    A PDF copy of the presentation will be sent to all attendees after the event.

  • (FREE) NUVATION ENERGY: Course 3 of 3 – Gain More Visibility Into Your Energy Storage System

    Wednesday, September 09, 2020 | 01:00 P.M. EDT USA

    Long-term ownership and management of an energy storage system requires high visibility into the batteries to enable problem identification and resolution, compare actual vs. predicted degradation curves, and plan for capacity augmentation. Real-time diagnostics and historical battery health data can be utilized to improve system reliability and reduce the total cost of ESS ownership. Join Nuvation Energy CEO Michael Worry for an examination of how battery data analytics can be retrieved from the BMS and utilized to optimize system maintenance and contribute to the long-term viability of the energy storage system.

    This webinar will focus on the following key topics:

    • Business impacts of low visibility into internal battery operation
    • Problems frequently encountered by operators in the field
    • “Cell to cloud” remote system diagnosis
    • Battery warranty tracking

    A PDF copy of the presentation will be sent to all attendees after the event.
