For dielectric coatings to effectively prevent arcing or breakdown voltage in electric vehicle (EV) battery packs, the following must work together:

• the right material or chemistry

• the ability to mix and spray that chemistry on ratio at a consistent flow rate

• an automation technique that handles specific part geometries

However, complex designs and applications often threaten dielectrics’ ability to safeguard EV batteries – and ultimately EV passengers. Robert Delgado, global market strategist for eMobility in the Industrial Division of Graco Inc., will explain how to simplify such difficulties without sacrificing battery performance and safety during this 60-minute webinar on Thursday 13 July at 3 p.m. CET / 9 a.m. ET.

Developing materials for next-generation EV batteries requires advanced analytical technologies such as Atomic Force Microscopy (AFM), NMR Spectroscopy, Energy Dispersive X-Ray Spectroscopy (EDS), Electron Backscatter Diffraction (EBSD), Wavelength Dispersive Spectroscopy (WDS), and Raman Imaging. This webinar will be divided into components:

• AFM – Applications of AFM that relate to nanoimaging of battery components and interfaces.

• SEM – Cleanliness, particle size, shape, and composition analysis of powders and electrodes using EDS, EBSD, and WDS.

• NMR –Leveraging diffusion and conductivity data from NMR for formulation development to gain insight into energy density along with charge/discharge performance.

• Raman Imaging – Investigating the cycling-induced chemical changes and degradation of cathodes, anodes and separators.

Electric vehicle development to replace a mature ICE counterpart requires out-of-the-box thinking. The adoption of simulation-driven methodology is not only vital to the optimal usage of human resources and materials, but also the most viable solution to innovation. The consolidation of vehicle platforms by vehicle manufacturers demands a modular approach for electric motor design, which in itself lends to shared technology across vehicle platforms and manufacturers.

In this webinar, we present the value of using a unified modeling and simulation process that leverages the CAD-CAE connectivity for developing a new electric drive system or re-using one from an existing vehicle program. With the creation of a modular, fully-parametric and simulation-friendly electric drive model, it is possible to explore untouched design possibilities and test all possible scenarios in a more affordable time frame—thereby, accelerating the vehicle development program and preventing valuable engineering resources from being wasted.

The development of vehicles powered by battery or hydrogen requires out-of-the-box thinking. The adoption of simulation-driven methodology is not only vital to the optimal usage of human resources and materials, but also the most viable solution to innovation. The consolidation of vehicle platforms by vehicle manufacturers demands a modular approach for electric motor and battery pack design, which in itself lends to shared technology across vehicle platforms and manufacturers.

While significant resources are allocated to develop new battery technologies, vehicle manufacturers are looking into alternative fuel sources such as hydrogen due to stringent timelines to eliminate the sales of internal combustion engine (ICE) based vehicles. Fuel cell electric vehicles (FCEVs) operating with green hydrogen technology are a promising alternative to battery electric vehicles (BEVs). Fuel cells are more suitable for large vehicles such as trucks and trains considering the challenging battery size requirements for such large vehicles. In addition, they require less expensive commodities while tending towards zero emission, zero waste and no grid impact.

In this webinar, we will share a simulation driven methodology that can be adopted at any stage of propulsion system development for both BEVs and FCEVs with a robust, industry validated connected process. This includes leveraging pre-packaged workflows that apply to electric vehicles such as inverters and electric drives, as well as to bipolar plates and gas diffusion layers in hydrogen fuel cells. This highly scalable, customizable process will empower propulsion system engineering teams to develop solutions that are both suitable for the vehicle platform and exceed industry requirements.

The session addresses a simple joining of materials with the highest conductivity joint – keeping electrical resistance (and heat generated) to a minimum – reducing heat, reducing cooling systems energy consumption- in tern contributing to increasing vehicle range.

• Extreme climate and weather conditions pose significant challenges to Li battery packs, including temperature fluctuations, moisture exposure, and mechanical stresses.

• High temperatures can accelerate the degradation of Li batteries, leading to reduced performance, shorter lifespan, and safety risks such as thermal runaway.

• Cold temperatures can decrease the battery’s capacity and increase internal resistance, impacting its efficiency and overall performance.

• Moisture exposure, whether from rain, humidity, or submersion, can cause corrosion and short circuits within the battery, leading to malfunctions or even failure.

• Mechanical stresses from vibrations, impacts, or thermal expansion/contraction can damage the battery’s structural integrity and electrical connections, compromising its performance and safety.

• Adhesives can help mitigate these challenges by providing insulation, sealing, and structural support to Li battery packs. They can offer thermal management properties, preventing heat buildup or dissipation, and act as a barrier against moisture ingress. Additionally, adhesives can enhance the mechanical strength and shock resistance of battery packs, protecting them from external forces. Proper adhesive selection and application ensure improved reliability, lifespan, and safety of Li battery packs in extreme climate and weather conditions.

When repurposing EV batteries for stationary applications, new application-specific requirements must be validated on the repurposed packs.

One such test is propagation (otherwise called cell-propagation, thermal runaway, or single-cell-design tolerance).

As these test methods generally require modifications to an existing cell or battery pack to implement the test, repurposed batteries add a new challenge, as they are already manufactured, so modifications for testing must be implemented at the test site.
