Since Tesla’s reveal of its new Semi and Roadster models, many technical analysts have been left scratching their collective heads. How can Tesla promise performance metrics far exceeding what’s currently physically and economically possible? According to one analyst, it may not be a...

As Elon Musk basks in the glow of meeting his 100-day challenge to install the world's largest utility battery in South Australia, another company is looking to take his crown. Hyundai Electric & Energy Systems Co. announced on November 23 it took an order for an industrial energy-storage...

As automakers develop more efficient electric motors, EVs pulling electrons from dirtier, coal-powered grids are as clean or cleaner than even the most efficient fossil-fueled cars when it comes to equivalent tailpipe emissions. But electric vehicles still have a supply-chain problem. A partnership...

Although Elon Musk is the name now associated with Tesla, the current CEO was not a founding figure in the electric-car startup. That honor goes to two men, Martin Eberhard and Marc Tarpenning. Eberhard subsequently sparred with Musk in and outside of court. Following his time at Tesla, Eberhard...

Tesla CEO Elon Musk made a bet that he'd build the world's largest lithium-ion battery in Australia in 100 days. If his company failed, Musk would personally pay for the project, but the battery is now ready for its first test ahead of full operation—and on schedule. The massive...

Electric cars provide a zero-emission driving experience, but one of the most important raw materials for their batteries—cobalt—has a supply chain that needs some work. About half of the world's cobalt supply comes from the Democratic Republic of Congo (DRC), a country with high rates...

It is just over five years since I bought my Better Place Renault 2012 Fluence ZE in Israel—and a little over five months since I returned it to Israel’s Renault importer for a cash settlement. By that time, the 22-kilowatt-hour battery capacity was down to 11.3 kwh, and a warning light...

As it stands today, Asia dominates the production of electric-car battery cells globally, with Japanese and Korean companies representing the bulk of the industry outside of booming Chinese makers. Europe, however, lacks a single major player in the fabrication and assembly of lithium-ion battery...

Electrification is starting to surge through the automotive industry as countries implement emission regulations and the cost of batteries and associated technology drops. While the automotive sector will clearly affect a larger group of people, numerous companies have shown that boats too can go...

Electric cars pale in comparison to gasoline or diesel-powered cars when it comes to the time presently required to add energy for more driving distance. Although automakers have begun to curb "range anxiety" with longer-distance electric cars, battery charging times on lengthy road trips remain a...

Many automakers have announced they will electrify entire vehicle portfolios in the years to come. With more electrified cars on the road, battery production will become increasingly more important. Adding to the positive outlook for lithium-ion cell makers is Volkswagen's potential partnership...

Dyson, the British appliance company best known for its bagless vacuum cleaners, has cleared up speculation that has persisted for nearly 10 years. Founder and chief engineer James Dyson officially confirmed his company is developing an electric car and is planning for a 2020 launch. Not only has...

While the United States federal government threatens to backslide on renewable energy, California and China continue to move at an aggressive pace to lead the world in zero-emission vehicles. However, there's another piece to the electric-car puzzle that China seems poised to lead as well: battery...

Over the past decade, advances in battery technology have progressed steadily, but not quite as quickly as impatient electric-car advocates might like. With electric cars and plug-in hybrids fast becoming part of every carmaker's lineup, durable, less expensive, and higher-capacity batteries are...

The latest reports on Tesla Model S durability and reliability should likely be considered a win for the Silicon Valley automaker. High-mileage cars aren't unusual, but we're only now starting to see the first truly high-mileage examples of electric cars. With less maintenance required compared to...

Renault hasn't tackled the home-energy storage market to the degree its alliance partner Nissan has, but it has found another use for "second-life" batteries. The French brand has worked with UK-based Connected Energy to install two electric-car DC fast-charging stations powered by second-life...

With the global introduction of the second-generation Nissan Leaf electric car due next week, one open question concerns the source of its battery cells. To date, Automotive Electric Supply Corporation—a joint venture between Nissan and Japanese electronics giant NEC—has supplied...

General Motors has informed "a few hundred" owners of 2017 Chevrolet Bolt EV electric cars that their cars could suffer from a problem with the lithium-ion battery pack that could cause it to fail without warning. The cars were among the very earliest Bolt EVs produced for public sale, so are...

Alkaline batteries have been a staple energy source for decades, but their potential has been capped by their chemical properties. Notably, alkaline batteries cannot be recharged, which means their application is often limited to single uses in small devices such as flashlights and remote controls...

The report that Toyota is planning an electric car with a solid-state battery for 2022 has led some fans and advocates to suggest huge new leaps in electric cars are imminent. The 2011 Nissan Leaf had an EPA-rated range of 75 miles combined; the comparable figure for a 2017 Chevrolet Bolt EV is 238...
