6 tips for creating high-throughput battery production in record time
Batteries represent nearly one third of the total price of a typical EV, and there’s a push to get that down to 20% or less by the end of this decade. In an effort to lower costs and accelerate production, the EV industry has been searching for ways to make the assembly process more efficient… Read more »
A closer look at high-power interconnects and disconnects
In the electrical/electronic world, the terms interconnect and disconnect both refer to a means of joining two sides of a circuit together. The subtle—and entirely informal—difference is that an interconnect is directly or manually operated (inserting a plug into a jack, for example) while a disconnect is indirectly or automatically operated, for example the moving… Read more »
How to make heavy-duty electric trucks work in practice
Fleets tested Volvo VNR Electric Class 8 tractors for three years: Here’s what they learned. Large commercial trucks and other heavy equipment have run on diesel fuel for many decades now. Requirements for more aggressive emission after-treatment and the hardware to achieve that add cost and complexity for fleet operators. Rising fuel-economy standards during the… Read more »
Researchers aim to improve rare-earth-free magnets through microstructure engineering
Researchers from the DOE’s Critical Materials Institute (CMI) and Ames National Laboratory have developed a new method of manufacturing manganese bismuth (MnBi) magnets based on microstructure engineering. They describe their wok in “Engineering microstructure to improve coercivity of bulk MnBi magnet,” published in the Journal of Magnetism and Magnetic Materials. Permanent magnets used for electric… Read more »
Here’s why oil and gas companies are racing to invest billions in EV charging
As regular Charged readers know, oil companies have been on an EV charging spending spree. They’re getting into public charging in a big way, and it goes far beyond just installing chargers at their gas stations. Oil majors including bp, Shell and Total have been buying up companies at all points along the charging value… Read more »
Planning permission granted for lithium hydroxide refinery in Teesside, UK
Tees Valley Lithium (TVL), a subsidiary of Alkemy Capital Investments, has received planning permission to build a lithium hydroxide refinery at the Wilton International Chemicals Park in Teesside, UK, following an environmental impact assessment and local consultation over an 18-month period. Construction on the $300-million facility, which will supply the EV battery industry, will begin in 2023, and… Read more »
Ukraine signs COP27 pledge to electrify medium- and heavy-duty vehicles
It might seem that the government of Ukraine has more urgent matters to worry about at the moment than promoting EVs. However, the war has provided the most powerful reminder imaginable of the importance of phasing out fossil fuels. Furthermore, Ukraine is one of the largest markets for trucks in Europe. So in fact, it’s… Read more »
It’s about time: the 6 phases of thermal runaway propagation
Sponsored by Aspen AerogelsThermal runaway propagation is a complex challenge. No matter the cell chemistry or pack architecture, lithium-ion batteries are at risk of experiencing a thermal runaway event. Although there is no one-size-fits-all solution, battery engineers do not need to reinvent the wheel when developing a solution to meet critical safety requirements. By understanding… Read more »
Swiss startup Morand launches fast charging energy storage system combining batteries and ultracapacitors
Swiss technology startup Morand has launched a hybrid energy storage system that combines the characteristics of an ultracapacitor with that of a chemical battery to create “a durable and ultra-fast energy pack that can be usefully recharged in seconds.” Morand says its eTechnology is designed for applications that require fast, frequent charges of around 5… Read more »
