Sponsored by Hioki. A key challenge in developing Battery Electric Vehicles (BEVs) is extending the driving range through improved energy efficiency. Unlike fossil fuels, batteries have a lower energy density, necessitating large-capacity batteries to match the range of internal combustion engines, which inadvertently increases vehicle weight and decreases energy efficiency. Thus, there is a pressing… Read more »

Under Fire: Reevaluating Torch and Grit Testing Parameters
Sponsored by Aspen Aerogels. The safety of Li-ion batteries relies on containing single-cell thermal runaway (TR) events so that they cannot propagate into adjacent cells, triggering a cascading failure. While the thermal energy released during a runaway event can take multiple pathways, the most significant are: The first can be controlled with high-performance insulation materials… Read more »
A twist in ultrasonic metal welding
Sponsored by Telsonic. Ultrasonic-based processes and EVs have much in common: efficiency, performance capability, reliability, connectivity, and eco-friendliness are among the essential characteristics that they both possess. The torsional ultrasonic welding procedure called SONIQTWIST® was developed by Telsonic AG in 2006 and quickly established itself as the joining procedure for a great variety of plastics… Read more »
Energy expert: Updated US Hydrogen Strategy is better, but still designed to prop up the fossil fuel industry
Michael Barnard writes on a wide variety of e-mobility and renewable energy topics. In a recent article for CleanTechnica, he discusses the latest edition of the US National Clean Hydrogen Strategy and Roadmap, a policy document that the DOE produces and updates periodically. Barnard’s piece is a detailed and highly technical discussion of a complex… Read more »
Will EV adoption “crash the grid?”
One of the favorite tropes of the anti-EV crowd is that converting all vehicles to EVs will “crash the grid.” Those of us who regularly speak with execs at electric utilities and charging infrastructure providers aren’t too worried about this. However, as they say, the plural of anecdote is not data, so perhaps a mathematical… Read more »
Designing DC fast chargers for next-gen EVs
Sponsored by LittelfuseSupercharged solutions that provide for fast charging reliability, efficiency, and safety The adoption of electric vehicles will reduce pollution and help slow the effects of climate change. A significant impediment to broader EV adoption is both a public charging infrastructure that can support long-distance travel and chargers that can recharge an EV battery… Read more »
Amorim Cork Composites introduces new range of sealants for EV batteries
Portugal-based Amorim Cork Composites, building on past development of sealing and aerospace applications, has introduced a range of products for sealing, housing and cell spacing that are designed to protect key components of EV batteries by preventing heat propagation during thermal runaway episodes. According to Amorim, cork’s low density, low thermal conductivity, heat resistance, cushioning… 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 »
ORNL licenses liquid-to-solid electrolyte technology to startup Safire
The DOE’s Oak Ridge National Laboratory (ORNL) has licensed a new battery electrolyte technology to Safire Technology Group, a battery tech startup formerly known as BTRY. The collection of five patented technologies is intended to be a drop-in additive for lithium-ion batteries. It’s designed to prevent explosions and fire from impact by altering the electrolyte… Read more »
