Elon Musk is aware of how to make promises. Even with the aid of his very own standards, the promises made last week simultaneously as introducing new Tesla cars—the heavy-duty Semi Truck and the fast Roadster—are monuments of envelope-pushing. To deliver, following shut observers of battery generation, Tesla would have to some distance exceed what is presently possible.
Take the Tesla Semi: Musk vowed it would haul an unheard of 80,000 kilos for 500 miles on an unmarried fee, then recharge four hundred miles of range in the half-hour. That would require, based on Bloomberg estimates, a charging gadget that is ten instances more powerful than one of the quickest battery-charging networks on the street today—Tesla’s personal Superchargers. As a result, the diminutive Tesla Roadster is promised to be the fastest production car ever built. But that achievement might imply squeezing into its tiny body a battery twice as powerful as the most important battery presently to be had in an electrically powered vehicle.
These claims are up to now beyond cutting-edge industry standards for electric-powered automobiles that they would require both advances in battery generation or brand new information of ways batteries are put to use, stated Sam Jaffe, battery analyst for Cairn Energy Research in Boulder, Colorado. In a few cases, professionals suspect Tesla is probably banking on technological upgrades between now and when new automobiles are surely prepared for transport.

“I do not suppose they may be mendacity,” Jaffe said. “I just assume they left something out of the general public screen that might have defined how those numbers paintings.” So here are 4 of Tesla’s most provocative battery claims—and a try and puzzle out how they are probably accomplished. When Musk took the level in an airport hangar in Hawthorne, California, his first proclamation turned into the Tesla Semi’s range: A fully loaded truck could be capable of the journey at highway speeds for 500 miles. The preceding record-holder, unveiled by Daimler in October, is a truck that maxes out at 220 miles.
A heavy-obligation, the long-range truck is the toughest car to electrify while nevertheless turning earnings, stated Menahem Anderman, president of Total Battery Consulting Inc., in Oregon House, California. Anyway, Tesla can be doing it to show a factor. “If you could make a semi-truck with batteries,” Anderman said, “then you can make the whole thing else with batteries.” Tesla is making its vehicles more efficient by reducing wind drag to degrees corresponding to those of sports automobiles.
But even though Tesla achieves document-breaking performance for the truck, it would nevertheless require a battery ability someplace from six hundred kilowatt-hours to 1,000 kilowatt-hours to supply Musk’s claims, in keeping with estimates from Bloomberg New Energy Finance. Split the distinction at 800 kWh, and it would imply a battery that weighs more than 10,000 pounds and expenses more than $ 100,000—even before you construct the truck around it. Tesla has priced the car with 500-mile variety at $one hundred eighty,000, less than the predicted prices of 7 analysts surveyed through Bloomberg, and says gas financial savings will bring about a –year payback compared to diesel.
One aspect Tesla has going for its miles is the falling rate of batteries. Musk may be banking on battery upgrades between now and the early 2020s for its truck to make monetary sense. The first Tesla Semis may not hit the road until past due 2019; even then, production might start slowly. Most fleet operators will need to test the vans before considering going all-in. By the time Tesla gets massive orders, batteries need to be valued significantly much less.
Tesla Megachargers: Four Hundred Miles in 30 Minutes
Musk’s claim that the truck may accumulate four hundred miles of price in half-hour would allow the Semi to reap the first authentic lengthy-haul levels in the enterprise. A motive force may start the day with 500 miles of variety, top off the battery at lunch, and be able to complete driving the U.S. Criminal limU.S.f eleven hours in a day with variety to spare. But doing so would require a charger in contrast to something visible earlier. “I don’t understand how that works,” said Salim Morsy, electric car analyst at Bloomberg New Energy Finance. “I sincerely don’t.” Tesla is claiming charging speeds that might be faster than something to be had now, and its customers pay well beneath common marketplace rates to get entry to the network.
Tesla’s modern technology of high-speed Superchargers has an electrical output of 120 kilowatts. It may add about a hundred and eighty miles to the battery in a Model S sedan in a half-hour. But that’s for a passenger car, not a loaded truck. So, to meet Tesla’s claim of four hundred miles in a half-hour for a semi-wearing eighty 000 kilos might require its new Megachargers to obtain the output of greater than 1200 kW—or more than ten times higher than Tesla’s quickest chargers to be had nowadays.
Joe Fath, the fund supervisor for T. Rowe Price Group Inc., Tesla’s 7th-biggest shareholder, stated that previous to the disclosing idea, Tesla’s heavy-responsibility truck was probably able to deal with approximately 1 / 4 of the hauling duties achieved by the most important heavy-obligation freight vehicles, referred to as Class 8 semis. In North America on my own, these large trucks account for about $30 billion in sales each year, in line with industry information tracked via Bloomberg. The guarantees in Musk’s presentation persuaded Fath that Tesla could compete in almost -two-thirds of the Class 8 market. “If they execute,” he stated, “they have a massive opportunity.”
Guaranteed Charging Rates of 7 Cents consistent with kWh
The sticky label rate of any electric-powered truck, irrespective of length, is better than its diesel equivalent because of the batteries, which on my can price as plenty as a few well-known diesel vehicles. The $one hundred eighty,000 Tesla Semi will compete with diesel that cost as low as $one hundred,000. The trick is to offset those higher upfront fees through decreased maintenance and gasoline savings. Perhaps Tesla’s maximum head-scratching revelation is that it will assure truckers energy rates of 7 cents consistent with kilowatt-hour. That may want to bring about fuel savings of greater than $30,000 a year for a few truckers, in step with Bloomberg estimates. Partly, Musk said, this could be done by adding solar energy and massive battery packs at the charging stations.
While the economics of the sort of plan range by using region, under any situation that BNEF’s Morsy expects, Tesla could be closely subsidizing the ones strength prices for customers. He hoped that Tesla would pay at least forty cents in keeping with kilowatt-hour, in common, for every 7 cents paid using a trucking company. “There’s no way you could reconcile 7 cents a kilowatt-hour with whatever on the grid that puts a megawatt-hour of strength into a battery,” Morsy said. “That does not exist.” That can also sound like a disastrous economic plan. However, it is no one-of-a-kind from what Tesla does for its present-day Supercharger community. Tesla gives free energy to a maximum of its Model S and Model X customers even as it pays nearly $1 per step per kilowatt-hour to supply it, Morsy said. That quantity to a subsidy of as much as $1,000 in line with the vehicle in 2017.
Many electric-powered utilities base their business costs on the peak quantity of electricity that a customer attracts simultaneously, even though that peak occurs simplest for a short length. Tesla’s Mega charger stations would incur extraordinarily high costs by drawing much strength quickly. The pleasant chance for mitigating those charges is to build Megachargers at present truck terminals that already draw quite a little power, Morsy stated, and by way of including big battery packs that can spread demand over the years. From another attitude, these subsidies to aid Megachargers will be a boon to Tesla’s stability sheet as it wades into an entirely new enterprise. It permits the organization to maximize its upfront revenue by charging lots for the vans while spreading out the value of a building and operating the charging community through the years.
A Tiny Roadster With a 620-mile Range
Tesla claims its new $ 2,000 Roadster is the fastest production car ever made, clocking 0 to 60 in 1. Nine seconds. Even crazier is the auto’s exceptional battery range: some 620 miles on an unmarried rate. That’s an extended range than any battery-powered vehicle on the street—nearly twice as long as Tesla’s class-leading Model S and Model X. To acquire such energy and variety, Musk stated the tiny Roadster would want to percent a large two hundred-kilowatt-hour battery. That’s twice the size of any battery Tesla presently has on the street. Musk has previously stated he won’t make the packs larger at the Model S and Model X because of space constraints. So how can he double the % length of the smaller Roadster? BNEF’s Morsy has a twofold answer. First, he expects Tesla will likely double-stack battery packs, one on top of the alternative, underneath the Roadster’s floor. That creates some engineering problems for the battery-management gadget. However, the ones have to be now, not insurmountable. Still, Morsy said, the batteries required might be too huge to fit in such a small frame.
“I certainly don’t think the auto you noticed final week had the total 200-kilowatt hours in it,” Morsy stated. “I don’t think it’s physically viable to try this right now.” But, again, Musk may be banking in the future. While Tesla commenced taking deposits on the Roadster immediately—$50,000 for the bottom version—the primary cars might not be brought until 2020. Meanwhile, battery density has been improving at a 7.5 percent month fee, which means that packs may be smaller and extra powerful by the time manufacturing begins, even without a chief leap forward in battery chemistry. “The fashion in battery density is, I suppose, significant to any declaration Tesla made about both the Roadster and the Semi,” Morsy stated. “That’s completely fair. The assumptions on p.C. In 2020, it shouldn’t be the identical ones you operate today.” The Semi and Roadster unveilings raised many questions about Tesla’s battery competencies and plans for expanding the markets in which electric-powered vehicles are aggressive. Even Musk may need a few more years to figure out all the solutions.
