When the charging station is (solely) 93 million miles away » Behind the Headlines


Lightyear has had an ideal month. First, they introduced that their prototype automobile drives over 440 miles (770 km) on a single cost.  And that’s on a battery cost of simply 60 kWh.

The Lightyear One prototype zipped across the take a look at monitor with a little bit assist from the massive charging station within the sky. This energy supply is, on common, 93 million miles ( 149.6 million km) from Earth.

“440 miles is a giant deal, however the greater deal is that the Lightyear One did it a comparatively small battery pack,” Motortrend reported. “’So what?’ you may be considering. Lucid and Tesla each have high-dollar, high-range EVs that may crack the 400 mile mark. That’s true, however the Lightyear One did what Tesla and Lucid can do however with a a lot smaller battery pack.”

And, as Motortrend famous, Lightyear is focusing on supply to its first clients in 2022. This brings us to the second splash of stories from Lightyear. Lightyear has partnered with a producer to construct its solar-powered automobile. Based on The Verge, Lightyear is working with Valmet Automotive, a producer that has constructed automobiles for Mercedes-Benz, Saab, and Porsche.

Aerodynamics vs. photo voltaic panel floor tradeoff

The important thing to the vary of the Lightyear One has been maximizing photo voltaic charging whereas minimizing air drag.

Lightyear One’s aerodynamic form provides to the automobile’s excessive effectivity. It’s lengthy with a slope that resembles the cross-section of an airplane wing. Different choices, corresponding to including wheel covers to the rear tires and changing aspect mirrors with cameras, squeezed out much more effectivity. Wind tunnel checks confirmed that Lightyear One broke the file for being essentially the most aerodynamic five-seater electrical automobile so far.

When contemplating the automobile’s roof, they wanted to seek out the correct stability between a very flat, large form that might maximize daylight publicity, and one with curves that would cut back wind resistance. By operating simulations in Simulink, they have been capable of scrutinize these sorts of design tweaks and see the place one of the best tradeoffs have been to enhance effectivity.
