Battery Management Systems
( 电池管理系统 )

2020年4月1日~2日


As the need for increased capacity and lifespan of lithium-ion batteries continues to grow, creating a safe and reliable battery management system is one of the biggest challenges facing battery engineers. The Battery Management Systems conference program, part of this year's International Battery Seminar & Exhibit, will bring together top scientists as they discuss how to extend the life of their battery packs and use battery management systems to maintain storage capacity and ensure that batteries run within safe conditions. High-level cell engineers and R&D scientists will discuss monitoring state-of-health, state-of-charge, designing internal battery pack topology, new monitoring methods, balancing mechanisms, and simplifying circuitry to develop long-lasting and reliable batteries.

3:55 Effects of Local Phenomena on Battery Degradation and Safety

Arnold_CraigCraig Arnold, PhD, Director, Princeton Institute for the Science and Technology of Materials, Princeton University

Here we discuss effects in Li-ion batteries in which local nonuniformities in battery construction or mechanical stress can couple into the electrochemical processes of the system and lead to accelerated decay and safety concerns. We present the relevant mechanisms and discuss methods of mitigating these effects in real systems.

4:25 A Frequency Response Interpretation of Transfer Function Models for Porous-Electrode Lithium-Ion Cell Internal Variables

Plett_GregGregory Plett, PhD, Professor, Electrical and Computer Engineering, University of Colorado, Colorado Springs

Frequency responses computed from transfer functions convey important information about system dynamic behavior. Applied to batteries, we normally consider electrochemical impedance spectroscopy (EIS), a spectral characterization of cell output voltage to input current. This talk expands the standard analysis by first presenting a full-order (pseudo-2D) model incorporating a double-layer effect and then derives closed-form transfer functions enabling the calculation of individual frequency responses for internal electrochemical variables.

4:55 A Model Predictive Control (MPC) Approach to Power Limit Estimation Using a Coupled Electro-Thermal Empirical Model and a Nonlinear Kalman Filter

Trimboli_ScottScott Trimboli, PhD, Assistant Professor, College of Engineering & Applied Sciences, University of Colorado, Colorado Springs

Electric vehicle energy storage systems using lithium-ion batteries require constant monitoring to ensure safe and reliable performance. Limits on applied current, cell voltage and temperature are essential to meeting these objectives. This presentation describes a novel application of model predictive control and a sigma-point Kalman filter to produce optimal estimates of charge/discharge power, which adhere to constraints on key problem variables to ensure safe and efficient operation.

IMPROVING SOH AND SOC

9:00 Chairperson’s Remarks

Joshua Lamb, PhD, Principal Member of the Technical Staff, Power Sources R&D, Sandia National Laboratories

9:05 Advanced Single Cell Thermal Runaway Initiation Techniques

Lamb_JoshuaJoshua Lamb, PhD, Principal Member of the Technical Staff, Power Sources R&D, Sandia National Laboratories

Recent work at Sandia has looked at non-traditional thermal runaway triggers that can be applied to off-the-shelf cells. Single cells were initiated using a fiber coupled laser to create a localized failure on a cell. The ability to initiate single cell failure in both pouch and cylindrical cells is in multiple orientations is demonstrated. Limited cell to cell propagation initiated by the laser is performed as well, demonstrating the technique as a low energy initiation source for propagation testing.

9:35 Towards Next Generation of Battery Models

Mohr_DirkDirk Mohr, PhD, Professor, Mechanical Engineering, MIT

This presentation shows the latest computational models and testing techniques developed by an Industrial Consortium headed by MIT’s Impact and Crashworthiness Lab, including: i) the development of anisotropic mechanical models of battery cells; ii) machine learning-based models for predicting battery deformation and failure; and iii) results from in situ tomography observation during battery crushing.

PREVENTING DEGRADATION

11:20 Trends in Safety with State of Charge for Lithium-Ion Cells and Batteries

Judith Jeevarajan, PhD, Research Director, Electrochemical Safety, Underwriters Laboratories, Inc.

The transportation authorities (DoT and ICAO) require that lithium-ion cells and batteries should be shipped at states of charge that are 30% or less.  Research in the area of safety versus states of charge is not prevalent and not much data can be found in the literature.  UL has carried out an extensive test program that includes cells with different lithium-ion cathode chemistries, different form factors and two different battery designs.  Cell and battery types included those that were considered counterfeit also.  The trends observed in safety with states of charge for cells and battery designs will be presented.

2:25 Coding the Intuition: A Data-Driven Approach to Probe the Stability of Dialkoxy Benzene-Based Catholyte Molecules for Nonaqueous Redox Flow Batteries

Zhang_LuLu Zhang, PhD, Chemist, Energy Storage, Argonne National Laboratory

The stability of redox active molecules is a paramount property that dramatically affects the cycling performance in redox flow batteries. Computationally, it requires a huge amount of resources to exhaustively iterate all the possible degradation pathways in order to estimate the stability of active species, such as radical cations. QSAR, or quantitative structure–activity relationship, provides an interesting approach to correlate chemical structures and properties based on the idea that property changes are all coming from structure modifications.

2:55 Low-Resistance Negative Electrodes for Fast-Charging Lithium-Ion Batteries

Ebner_MartinMartin Ebner, PhD, CEO, Battrion AG

We present a novel fabrication technology that reduces the resistance of negative electrodes of lithium-ion batteries (LIBs). Fast charging of high-energy density LIBs is limited by increased degradation brought about by lithium plating on the negative electrode. In this talk, we investigate how reduced negative electrode resistance leads to shorter charging time without compromising energy density, safety, and lifetime.

3:25 Battery Module/Pack Testing: Current Challenges & Opportunities

Martin Weiss, Product Director, NH Research (NHR)

Battery module/pack testing is critical across all stages of battery R&D and production, but traditional methods of battery testing are an extremely time-consuming and costly challenge. Today, testing requires more flexibility and scalability to meet the growing demands of electrification and high performance. This presentation will equip battery manufacturers with cutting-edge technologies, trends, and test solutions for battery module/pack testing.

Chemtrec 3:55 Complying with New Mandate for Lithium Battery Test Summaries

Kevin Bryan, Senior Business Development Manager, Sales, CHEMTREC

Kevin Bryan, CHEMTREC, will present on a new system developed to assist industry with regulatory compliance of the new lithium battery test summary mandate as specified in the United Nations Manual of Tests and Criteria, Part III, sub-section 38.3. Users will have the ability to minimize their own resources with capabilities to upload, modify, download, and distribute test summary documents, and request CHEMTREC to source unavailable test summary documents.

The prospects for lithium-ion are justifiably receiving major attention. Projected growth rates are impressive and numerous market drivers and trends (vehicle electrification, 5G, wearables, ESS, IoT, the cloud) reinforce the potential for even higher growth. Responding to the challenge, Li-ion technology has been steadily improving even as costs have been decreasing. Requirements for even higher energy are stimulating massive R&D efforts to bring next generation materials to market. The roadmap to 2030 offers many opportunities, but not without major challenges.
