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

Preventing Thermal Runaway in Energy Storage Systems (ESS)
From air transportation to electric vehicles and most recently “Hover Boards”, our industry is painfully aware of the over-discharge malfunctions associated with high-energy lithium-ion batteries, yet according to recent studies, nearly 70% of all Energy Storage Systems currently deployed are lithium-ion. Avoiding the pitfalls of utilizing greater energy density in larger installations is what will be discussed. Michelle will walk through the recent innovations from materials and process tracking in battery manufacturing to comprehensive control of cells in a fully deployed system. Incorporating lessons learned from recent failure investigations by the NTSB and FAA as well as new DoE mandates, Michelle will discuss how to achieve and in some areas surpass the new emerging safety certifications for a multi-megawatt energy storage system.
This webinar will focus on the following key topics:
• Making batteries safe or making safe batteries? (control & mitigation)
• Cell manufacture tracking, certification and response
– NTSB & DoE analysis and current situation
• Incorporating advanced battery management systems (BMS)
– Active cell dynamic balancing
– Cell replacement (hot-swapping)
– System reconfiguration
– Energy density scalability

Battery Analytics Tutorial Course 2/3: Data Capture and Trend Reporting
This one-hour webinar is Part 2 of a 3-part series. Battery management systems take large amounts of sensor data readings on a continual basis as part of their functionality. Battery analytics involves leveraging battery performance data for tasks such as identifying issues that can reduce battery life, flagging behavior that can negatively impact energy storage system performance, and predicting remaining cell and pack life.
This webinar will focus on the following key topics:
• Sensor data capture, aggregation and manipulation into performance reports
• Real-life examples will be shared, where aggregated historical data was analyzed and anomalous behaviors were identified
• Also shared will be the inspections and testing of the pack to identify the cause of the anomalous behavior, and the discovery and resolution of the problems that caused the anomalies

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
