The battery has no alien technology to help the electric truck is a concept

Foreign magazines recently wrote that in the eyes of Musk, electrifying the world is his ultimate goal, and electric buses and electric trucks are indispensable in this big game. Electric buses are nothing new, but the Tesla electric trucks that will unveil the mystery in September this year can’t help but imagine that if Musk’s Haikou can be realized, he can directly reduce the traffic in the United States. One quarter of the greenhouse gas emissions are gone. But the question is, can Musk really create an electric truck that revolutionizes the transportation industry?

In theory, unless Musk gets any extraterrestrial technology in battery technology, he probably won't be able to get an electric artifact that can "annihilate" American long-distance trucks. The assertion came from a paper by researchers at Carnegie Mellon University who found that electric vehicle cruising range could be stuck at the limit of 300 miles (about 482 kilometers), and such vehicles are expensive and have limited carrying capacity. After all, the weight and volume of the battery can be no small.

“The technical difficulty of an electric truck is comparable to that of an electric plane.” said Wenkat-Vistwanashan, one of the authors of the paper, and he was co-author of the study with Saxek-Spirit. . Both of them studied the truck's average load, average range and a range of truck-specific physical parameters such as towing system, air density, rolling resistance and overall powertrain efficiency.

If Tesla's electric trucks are still equipped with a lithium battery system and the power-to-weight ratio can reach the level of 243KW/KG of the existing Tesla vehicles, an electric truck will be loaded with a goal of 600 miles. 14 tons, while 900 miles requires 22 tons of batteries. According to the current price of batteries, 600 mile battery life costs up to 290,000 US dollars (about 1.97 million US dollars), while 900 mile battery life needs to buy 450,000 US dollars of batteries, but in fact the same level of diesel trucks on the market One car sold for $120,000.

Of course, cost is not the only problem. More importantly, the federal decree limits the total weight of the truck to 40 tons. If the weight of the car and the tire is added, it is feared that the actual cargo load of the 600-mile electric truck will be only 9 tons, while the average truck-loading capacity is average. Up to 16 tons. In this industry that pursues efficiency, I am afraid that the problem of weak cargo capacity is simply unacceptable. In addition, the charging time of huge battery packs has to be considered, and it is also an important factor affecting efficiency.

"Integrated with the above issues, we believe that 300-350 miles of battery life may be the limit of electric trucks. Exceeding this figure, the battery of electric trucks will not only be heavy, but the cost will be too high," said Viswanashan.

However, such endurance is more suitable for taking on short-term repetitive tasks, it will not add more pressure to the environment of heavily polluted areas. But obviously, Mask is not here, he wants to swallow the huge market of long-distance intercontinental trucks.

For electric trucks, Tesla officials have been ignorant, perhaps they really master the alien black technology. Wiswanathan believes that the next-generation battery pack will lower the price of a 600-mile battery to $180,000 and its load capacity will rise to 16 tons.

However, only three months, whether Musk can change the magic again, who can not tell.
