VW: German auto industry push to subsidize hydrogen is “nonsensical”
The latest battle in the War of the Energy Storage Media has broken out in Germany, where the Volkswagen Group and an auto industry lobbying group (the German Association of the Automotive Industry, or VDA) are at daggers drawn over the government’s proposed plan to implement the EU’s renewable energy directive. Germany’s Federal Ministry of… Read more »
Webinar: Multiphysics modeling of fuel cells
Battery electric vehicles and fuel cell vehicles have unique marketplaces. Electric vehicles that must minimize weight (e.g. heavy duty trucks and airplanes) consider fuel cells as a primary power source for electrification, as they reduce the significant battery weight associated with battery electric vehicles. Engineers are continuing to develop new fuel cell designs for vehicles…. Read more »
Mersen Fischerlink’s low-inductance busbar/capacitor assembly for SiC DC-link
Mersen has introduced a new capacitor and busbar sub-assembly, called Fischerlink 2.0. Traditionally, capacitors are connected to busbars by screw or solder connections, which may cause increased inductance in the sub-assembly. Mersen’s Fischerlink 2.0 uses laser welding to connect capacitor terminals to busbars, which the company says improves the overall performance of the assembly and… Read more »

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.
