California’s Aptera Motors today confirmed its battery supplier for its upcoming solar-supplemented, hyper-efficient three-wheeled cars: China’s EVE Energy. 

It plans to use cylindrical cells, in the same 2170 format that’s been used in the Tesla Model 3 and Model Y, as well as the Rivian R1T and others. The cells from EVE use NMC 811—meaning that their cathode composition follows a ratio of 80% nickel, 10% manganese, and 10% cobalt. 

As Aptera pushes toward production, it’s made a series of supplier announcements recently, including some technology that strays from the EV norm. It recently confirmed that it will source its in-wheel motors from industry leader Elaphe, with initial production from Slovenia potentially extending to the U.S. later. The Lordstown Endurance electric pickup, due to be made in Ohio later this year by Taiwan’s Foxconn, will also be an in-house motor trendsetter—with those motors made at a local facility. 

Although EVE Energy doesn’t yet power any high-profile EVs in the U.S., it maintains a strong reputation with Western automakers and makes a range of lithium-ion chemistries in pouch, prismatic, and cylindrical formats. It’s one of the four core battery suppliers for current BMW EVs—as BMW potentially makes a shift to cylindrical cells—and it’s made sample cells for StoreDot’s buzzworthy “100in5” cells that claim to be part of a strategy for adding 100 miles of range in five minutes of charging. 

The two-seat Aptera claims a 0-60 mph time of 3.5 seconds, with its range of up to 1,000 miles permitted with the help of a very lightweight construction, a 0.13 coefficient of drag, and solar cells that can restore up to 4.4 kwh, or 40 miles, of energy per day on a sunny day in California.

That’s led to the claim that in normal commutes, users may “never charge” for weeks or months. They also won't need to rely so heavily on fast-charging, and might be just fine with a spare 120V AC socket. 

Across versions offering a driving range from 250 miles up to 1,000 miles, the model starts at $25,900 and rises to $51,700. The company recently reported that it has more than 22,000 reservations and plans to build thousands of its vehicles starting later this year.

The federal government has put the kibosh on the possibility of some fun sounds to alert pedestrians. U.S. states are mapping out their pieces of a national EV charging network. And the Toyota Crown Hybrid Max takes a bow. This and more, here at Green Car Reports. Toyota has reconstituted its largest sedan, the Avalon, into the Crown by raising the ride height and the roofline a bit and adding some SUV cues. This “reimagined” sedan is the first Toyota model to offer its new Hybrid Max performance-hybrid system, which drives the wheels directly with electric motor torque in front...

States are submitting plans for how most of $5 billion earmarked by the infrastructure law will be allocated—with EV charging locations focused around alternative fuel corridors still being designated.

Tesla's Boombox feature might have soured regulators about flexibility in its so-called "quiet cars" rules mandating alternative artificial sounds to alert pedestrians.

The Crown offers a slightly higher ride height, two hybrid systems, and some SUV cues to veer away from the full-size Avalon it replaces.

Panasonic is building a U.S. battery “mega factory.” Hyundai revealed more about what the Ioniq 6 electric sedan gains versus Ioniq 5—and why it looks so different. And GM and Pilot are getting in the charging business. This and more, here at Green Car Reports. Look out Electrify...

Panasonic plans to achieve its energy-density boost partly with a new mix of additives that would allow individual battery cells within a pack to run at higher voltage.

Pilot and Flying J travel centers will host 500 DC fast-charging stations, all manned 24/7 and equipped with 350-kw chargers—with most to be installed by 2025.

How was Hyundai able to secure additional driving range from the Ioniq 6 given the same battery pack? An executive summed what the electric sedan gains.

The Hyundai Ioniq 6, confirmed for U.S. arrival in Q1 2023, looks very different than the Ioniq 5 crossover but has a lot in common.

Panasonic says that the $4 billion plant will make lithium-ion batteries for electric vehicles—likely for both Tesla and other automakers.
