EV batteries have the potential to overheat, leading to a thermal runaway event. But even milder temperatures have a negative effect on EV battery performance and longevity, making thermal management systems essential. In this presentation we will discuss a variety of configuration possibilities, with stiff and flexible sections as necessary, as well as highlight the… Read more »

The Goldilocks Problem: Balancing Internal Forces Within An EV Battery Module Or Pack
Li-ion cells often have strong opinions about their clamping pressures, wanting neither too hard, nor too soft. It’s a classic “Goldilocks problem,” with a sweet spot that balances electrochemical performance, cell life, and mechanical retention. Goldilocks also changes her mind, often, as the cells breathe and swell through a lifetime of usage. When designing modules… Read more »
Dual traction inverter demo with NXP’s S32K39 MCUs (Webinar)
During this presentation at next week’s Virtual Conference on EV Engineering, you will discover how NXP’s S32K39 dual traction inverter demo works. The S32K39 has the ability to run two 3-phase SIC or GAN-based inverter motors with 200KHz control loops while being ASIL D compliant with NXP´s FS26 PMIC and GD3162 gate driver. Reserve your… Read more »
State-of-the-art battery characterization: challenges and opportunities (Webinar)
Battery characterization is the foundation for the design and development of any battery energy storage system and is specifically important for inspection, validation, end-of-line testing, pack assembly, and BMS design purposes. In this free webinar, presented by Bitrode at our Spring Virtual Conference (April 17-20, 2023), we will introduce some of the industry standard protocols… Read more »
Identifying the root cause of particle contamination in electronic automotive components
Sponsored by Zeiss. Production processes, the production environment, and the final packaging all have an influence on component cleanliness. As a result, compliance agreements with limiting values often need to be implemented between the customer and supplier or between product development and production. This means that the cleanliness requirements are not fixed and can be… Read more »
GM selects PyroPhobic’s LithiumPrevent 200 fire safety material for its Ultium battery platform
PyroPhobic Systems, a provider of fire-resistant thermoplastic resins for batteries, has announced that its LithiumPrevent 200 material has been selected for application in GM’s Ultium battery platform. LithiumPrevent 200 has “unique intumescent properties, meaning it expands to create a barrier, reducing the propagation of fire,” says PyroPhobic. “Injection-molded into EV battery pack components, LithiumPrevent 200… Read more »
Fluorinated boosters: Enhancements for dielectric fluids in EV batteries
Sponsored by ArkemaIn the near future, the number of electric vehicles on roads across the globe will increase dramatically. This growth is being driven by new regulations, increased public demand for greener transportation and, ultimately, the goal of reducing greenhouse gas emissions. In fact, according to the UN Climate Change Conference, the global automotive fleet… Read more »
Can an EV go through a car wash? Common Google searches reveal the level of cluelessness about EVs
The greatest obstacle to EV adoption may not be range anxiety, unreliable public charging, or even the high upfront costs, but rather the lack of consumer awareness about EVs. Like most electric drivers, I regularly field ridiculous questions both on the road and online, and some of the things people say to me reveal the… Read more »
Amping-up EV batteries with a materials mindset
Sponsored by DupontSponsored by Dupont Before this decade is over, even conservative estimates indicate that at least two out of three cars produced in the world will be electrically powered. This figure accounts for both fully battery-powered and hybrid propulsion system vehicles. There are some hard truths involved in engineering mobility for the future. Systems,… Read more »
The benefits of smart welding battery packs
Sponsored by Hesse Mechatronics Benefits of Smart Welding There are many types of welding used for the interconnection of battery packs. Laser, resistance, spot, etc. are just a few of the common types. Smart Welding was developed by Hesse Mechatronics to offer an alternative option. Smart Welding is “wire bonding without the wire” as it continues to… Read more »
