Clearing the roadblocks to electrification of heavy-duty trucks
Q&A with electric truck expert Rustam Kocher Medium- and heavy-duty vehicles make up a small fraction of the vehicles on the road, but they generate a disproportionate amount of pollution. Therefore, electrifying them is critical to reducing emissions. Furthermore, the case for electric trucks and buses would seem to be an easy one to make…. Read more »
Tesla is outselling Toyota in California
Tesla’s founders set out to sell “not just the best electric cars, but the best cars.” In several markets around the world, the company’s EVs have now become the best-selling cars. In Q2 of this year, Tesla had the two best-selling cars in California by a wide margin, helping to push the market share of… Read more »
Li-S Energy claims to boost energy density by 45% with new 20-layer lithium-sulfur battery
Li-S Energy has revealed its first 20-layer battery cells using its third-generation semi-solid-state lithium-sulfur (GEN3 Li-S) technology. GEN3 Li-S 20-layer battery cells use a patented low-flammability electrolyte Li-nanomesh technology and Boron Nitride Nanotubes (BNNTs) to prevent dendrite formation. Compared to the company’s second-generation lithium-sulfur cells, the new cells offer greater energy density and more safety,… Read more »
PowerCo says its new cell production procedure saves huge amounts of energy and floor space
Volkswagen Group-owned battery manufacturer PowerCo SE plans to introduce a new battery cell manufacturing method in its plants in Europe and North America. PowerCo predicts that its new Dry Coating procedure may save 30% of energy consumption and 15% of floor area, saving hundreds of millions of euros annually. According to a Joint Development Agreement,… Read more »
Does Toyota’s BEV Factory really represent a new direction?
Toyota has a credibility problem when it comes to e-mobility. The giant automaker’s corporate right hand pursues a number of EV initiatives around the world, while its left hand continues to spread misinformation and lobby against pro-EV policies. Many are hopeful that the recent changes in the company’s executive suite portend a new, more electric… Read more »
Microchip launches E-Fuse Demonstrator to protect power electronics in EVs
US IC manufacturer Microchip Technology has released a high-voltage circuit protection board for 400-800 V batteries with a current rating of up to 30 amps for hybrid and electric vehicles. Due to its high-voltage solid-state architecture and silicon carbide (SiC) technology, the six-variant E-Fuse Demonstrator Board can detect and interrupt fault currents in microseconds, which… Read more »
