Battery Modeling and Simulations Using COMSOL Multiphysics®
(Updated Schedule: Session moved from Tuesday, Sep 1 to Thursday, Sep 3 at 10:30 am EDT)
The COMSOL Multiphysics® modeling and simulation software contains various tools for creating and running battery models. The level of detail ranges from single-reaction lumped cell models, used for simulating temperature distributions on large-scale battery modules and packs, to multireaction high-resolution electrode geometries on the nm-level, used for capacity fade, and design optimization of the various cell components and chemistries.
This talk will present an overview of various battery modeling approaches for thermal, performance, abuse, and capacity fade (aging) simulations. The talk will include live demonstrations of these concepts using the COMSOL Multiphysics® software.

Power Integrations’ SCALE-iDriver for SiC MOSFETs achieves AEC-Q100 automotive qualification
Power Integrations has announced that its SIC118xKQ SCALE-iDriver, a single-channel gate driver for silicon carbide (SiC) MOSFETs, is now certified to AEC-Q100 for automotive use. The drivers, which include safety and protection features, can be configured to support gate-drive voltage requirements of commonly used SiC MOSFETs. The SIC1182KQ (1,200 V) and SIC1181KQ (750 V) SCALE-iDriver… Read more »
USABC grants Physical Sciences $919,000 contract for Li-ion material coating assessment
The United States Advanced Battery Consortium (USABC) recently granted a $919,000 contract to Physical Sciences Inc. (PSI) to assess active coating material in order to verify whether this technology actually improves Li-ion cell-level energy density and lowers costs. The 18-month-long project, which began last year, will evaluate PSI cells to determine whether the company’s active… Read more »
UnitedSiC announces SiC FETs with RDS(on) of less than 10 mohms
Range and horsepower may get the headlines, but to powertrain designers, drain-source resistance, also known as RDS(on), is a sexy spec. Those in the know are excited over the news that UnitedSiC, a New Jersey-based manufacturer of silicon carbide (SiC) power semiconductors, is introducing four new SiC field-effect transistors (FETs) that boast RDS(on) levels of… Read more »
Cree to supply SiC semiconductors to ZF for electric drives
Cree, a US maker of silicon carbide (SiC) semiconductors, has partnered with German parts supplier ZF Friedrichshafen to supply SiC semiconductors for electric drives. ZF will initially use Cree’s technology to fulfill pre-existing orders from several auto manufacturers for silicon carbide-based electric drives, but ZF hopes to make silicon carbide electric drivelines available to the… Read more »
