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

Energy Storage RTE Tutorial Course 2/3: Ampere-Hour (Ah) RTE and Voltage Polarization Energy Losses
Many aqueous systems have water electrolysis to contend with, and above 70-80% SOC, RTE losses from this competing reaction can be significant. Management of these losses has been evolving for decades, and there are now tried and tested methods mostly related to charging algorithms & partial state of charge (pSOC) cycling. These methods will be reviewed. Relevant for every battery chemistry, Cell Voltage factors, will be separated into eight different components, four each, for the cathode and anode. These will be presented & described. The variables that affect them will be reviewed, including the effects of age & cycling and methods for their ongoing measurement. Techniques to reduce and mitigate polarization will be detailed & possible benefits will be quantified in terms of RTE & cost for different scenarios.
This webinar will focus on the following key topics:
• Ah Efficiency losses in aqueous systems
• Types of Voltage Polarization losses for all systems
• Strategies and plans for reducing & mitigating efficiency losses
• Improvement potential for different systems

Characterizing Performance and Determining Reliability of Batteries for Medical Applications
As the number and variety of battery powered devices used in medical applications grows, batteries are playing an ever more important role in determining the reliability of these devices. Unlike the portable consumer electronics industry where high unit volumes can justify the design and manufacturing of custom batteries, the medical device industry must often utilize standard, off-the-shelf batteries for their devices. Even when the production of custom batteries is justified, few battery manufacturers appreciate the level of quality and reliability that is required by the medical device industry.
In this webinar we will look at how to quantify the performance characteristics of batteries in a way that allows direct comparisons to be made between various vendors, form factors and chemistries. Case studies will be presented to demonstrate common mistakes made in battery selection and use, and methods for conducting accelerated aging studies will be discussed. When properly conducted, such aging studies can be used to identify potential reliability issues, monitor the manufacturing quality of the batteries and serve as a tool to aid in the selection and qualification of various battery vendors.
This webinar will focus on the following key topics:
• What do you need to know that is not on the specification sheets?
• How do you make apples-to-apples performance comparisons between different battery types?
• When is impedance and/or capacity matching important in multi-cell configurations?
• How can quality be compared between vendors?
• How can battery longevity be predicted in specific applications?

Addressing Engineering Challenges of Vehicle Electrification With Model-Based Systems Engineering
The concern for the environment and energy savings is changing the way we think about transportation. Wide spreading vehicle electrification – not only through Electric Vehicles (EV) and Hybrid Electric Vehicles (HEV), but also electrification in conventional vehicles – has become a common trend of the industry and the upcoming battlefield to install new leading positions. Accounting for costs, reliability, safety, performance, customer acceptance, infrastructure and design process makes manufacturers and suppliers facing new engineering challenges that need to be addressed in a very short time-frame.
Technologies used for electrification are causing a growing complexity in systems and components, and producing vehicles designed right, first, at reasonable costs make the implementation of collaborative mechatronic system simulation a decisive and mandatory step in the engineering process.
This webinar will focus on the following key topics:
• What are the global trends and challenges of vehicle electrification?
• What are the available technologies for reducing CO2 emissions?
• What are the benefits of stop & start and regenerative braking systems?
• How to characterize battery and optimize its thermal management?
• How do energy storage architectures impact battery aging?
