Battery Intelligence for Automotive Applications

How Smart Analysis of Your Battery Data Can Drive On-Time New Vehicle Launches, Optimal Performance, and Increased Margins

June 8-9, 2020

 

With the rapidly approaching electrification of the global vehicle fleet, automotive OEMs and key suppliers of battery packs, cells, and related components are under tremendous pressure to launch more new product lines in a tighter time frame than has ever been done before. Increasingly demanding consumer expectations around EV range and fast-charging ability, combined with a scarcity of qualified engineering talent, add to the challenges of shipping on-time and on-budget. Battery Intelligence – the intelligent analysis that unlocks the potential of data that these organizations are already collecting today – is the key to staying competitive in the electrified automotive landscape. The Battery Intelligence for Automotive Applications symposium will discuss how organizations can leverage a variety of data sources and contemporary analytical techniques (statistical analysis, machine learning, predictive modeling) to accelerate product development cycles, rapidly scale battery platforms across multiple vehicle lines, ensure supply chain integrity, eliminate guesswork to make fully data-driven design decisions, predict battery life, reduce pack overbuild and associated costs, and maximize the productivity of their engineering teams.

1:35 KEYNOTE PRESENTATION: Introduction to Battery Intelligence Systems (BIS)

Tal Sholklapper, CEO & Co-Founder, Voltaiq

While the industry is familiar with the battery and its battery management system (BMS), very few are aware of the critical need for a missing third layer, the Battery Intelligence System (BIS). The BIS is needed to unlock the significant advances in battery yield, energy density, and lifetime that the industry is calling for. Historically, product OEMs have treated batteries like black boxes, building mechanical and electrical interfaces to keep them stable. As batteries now become the make-or-break component in low-cost EVs and long-lived consumer electronics, companies need the BIS to provide a new level of insight and ensure that batteries are performant, reliable, and safe.

Bob Zollo, Solution Architect for Battery Testing, Keysight Technologies

The cell formation and grading section of the cell manufacturing line is the largest, most expensive, and most costly-to-operate portion of the manufacturing line. Today, some manufacturing lines are relying on 20 year old technology because it is safe and reliable. But advances in factory automation, cell forming electronics, measurements, data collection, and control systems offer the promise of improved productivity and efficiency, better flexibility and agility, and increased profitability. With the increased availability of process data and big data machine learning, it is further possible to feedback real-time insight and adapt the process on the fly to give the highest quality cell output.

3:55 Customizing Lithium-Ion Cells – From the First Materials Test to Series Production

3:00 Accelerating Battery Materials Discovery with Physics-Based Machine Learning

Austin Sendek, PhD, Founder and CEO, AIONICS

Discovering promising new materials is central to our ability to design better batteries, but research progress can be limited by an incomplete understanding of structure/property relationships, slow testing cycles, and overwhelmingly large numbers of candidate materials. New machine learning (ML) approaches offer a route to accelerated materials discovery by training predictive models on existing experimental data and then using these models to screen databases of candidate materials. Our research at Stanford University suggests that careful ML modeling can provide a significant acceleration in the rate of new materials discovery, even when trained on small amounts of data. In this talk, we present our research in using ML to accelerate electrode and electrolyte discovery, discuss best practices for the application of ML to materials design, and highlight the Aionics materials design software platform.

3:20 Prediction and Optimization of Battery Lifetime Using Machine Learning

Peter Attia, Senior Data Analyst, Tesla, Inc.

Battery lifetime testing is a major bottleneck in battery development due to both the number and the duration of required experiments. In this talk, I present work from my time at Stanford on both early prediction, which reduces the time per experiment by predicting the final cycle life using data from early cycles, and Bayesian optimization, which reduces the number of experiments by balancing exploration and exploitation to efficiently learn the parameter space.
