A NASCAR pit stop is only about 15 seconds, maybe they want to race it.

The battery is built by <http://www.desten.com/> Desten Group, Limited, a Chinese/German operation based in Hong Kong. Desten is cagey with details about its batteries, but claims "exceptionally high charge rates, 10C or higher," as well as power density in excess of 1600 watts per kilogram. The company says its cells can be fast charged and discharged 5,000 times before they drop to a capacity of 80 percent, suggesting excellent longevity particularly if the cars are charged slowly overnight most of the time." Definitely not a mistake... who knows whether or not they can actually do it, but there appears to be a few different companies claiming they're making batteries that can handle 10C charge rates. I think they're just using the battery manufacturer's charging claims, and not actually expecting to be able to charge a real car that fast.

I suppose it could be something like it's possible to charge these mystery batteries that fast, but it isn't actually going to happen in a real car.

At 3.11 miles per kW that would be a 100 kWh battery. OK, within the realm of posibilities. 4:40 minutes to 80% battery capacity. So 280 seconds or .077 hours to dump 83 kWh into the battery. 83/.077=1067 kW So you have to have 1 Megawatt power source to charge? 2223 amps of 480 service.
