  Adding Intelligent Battery Management to Lead-Acid Energy Storage Systems

  Lead batteries are resilient and have a low likelihood of catastrophic failure. However, their lifespan can be significantly reduced when operated outside of manufacturer specifications. The extension of lead battery life through active battery management is becoming a compelling value proposition for vendors of lead-based energy storage systems.

  The evolving regulatory environment governing energy storage safety is also impacting how both lead and lithium chemistries are to be managed moving forward. Join Nuvation CEO Michael Worry to explore the reasons why active battery management is becoming adopted in large-scale lead battery applications, and how the changing regulatory environment is impacting lead-based energy storage.

  This webinar will focus on the following key topics:

  • Controlling off-gassing in vented and VRLA lead batteries
  • Emerging functional safety regulations and UL 1973
  • Using a BMS to reduce the levelized cost of energy
  • Automating stack connection sequencing in a multi-stack ESS
  • Lead-based energy storage system deployments

  Solid Electrolytes and Bulk Scale Solid-State Batteries

  Recently, the push to move beyond Li – ion battery technology has grown. Several advanced battery technologies & chemistries have been identified as promising candidates including i) solid-state batteries with Li metal anode, ii) Li – S chemistries, iii) Li – air(oxygen), and iv) flow batteries. Although an engineered solution using liquids may be possible for some of these options, a solid electrolyte is an enabling technology for each of these beyond Li – ion alternatives. This webinar will introduce the operating principles of each of these cell technologies and solid electrolytes will be discussed in this context. The requirements of a solid electrolyte will be outlined & several state of the art solid electrolytes will be compared. Recent technical progress towards the fabrication of solid-state batteries will be reviewed. Finally, an overview of market applications for solid-state will be presented.

  This webinar will focus on the following key topics:

  • Overview of beyond Li – ion battery technologies enabled by solid electrolytes
  • Comparison of state of the art solid electrolytes
  • Recent technical progress towards solid-state batteries
  • Review of market applications for solid-state batteries

  BIS Tutorial Course 1/3: Introducing Battery Intelligence Systems (BIS)

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

  While the industry is familiar with the battery and its BMS (battery management system), very few are aware of the critical need for a missing third layer, the Battery Intelligence System (BIS) needed to enable the leap in battery yield, energy density, and lifetime the industry is calling for.

  Battery Intelligence Systems are needed to leverage the latent value sitting in data that companies are collecting today, including but not limited to: data generated in battery factories in Asia, product OEMs around the globe, and ‘data lakes’ collecting data from systems in the field.

  Your organization already has the building blocks to enable BIS. In this webinar we’ll show you the benefits of unlocking the value of your battery data.

  This webinar will focus on the following key topics:

  • The need for Battery Intelligence
  • State of the industry: insufficient resources to meet aggressive electrification goals
  • State of data today: “Treating it like a mushroom and watching it grow”
  • Automation of standard analyses
  • Traceability with Battery Digital Twins

  Understand and Prevent Battery Fires and Explosions – and Avoid Costly Failures Like the Samsung Note 7

  Modern batteries (eg Li-Ion) contain hazardous chemicals & they heat up during use: this combination always has the potential to cause fires & explosions. This presentation will focus on improving the understanding of how these incidents occur, what can be done to avoid them & how the risk can be minimized during early stage design.

  The Samsung Note 7 phone & Boeing Dreamliner airplane fires are very costly examples of how even large corporations fail to understand the potential fire risk of batteries.

  The solution lies in knowledge of heat generation rate during normal use & information about safe boundaries such as temperature, discharge rate & overcharge, in realistic situations that represent actual use conditions. Data from commercial batteries of different types 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 & explosions occur
  • How to design safer batteries though 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
