Some of the new Evs coming out are claiming ranges of 400 miles.
Watch out, Tesla. Rivian is gearing up to produce a sleek all-electric truck that can hit 60 mph in as little as 3.0 seconds. Depending on the battery option chosen, the R1T can travel 230 to 400-plus miles on a single charge, with prices starting in the high $60,000 range for the cheapest 105-kW-hr model. Each wheel has its own 197-hp electric motor, allowing precise torque vectoring at each wheel for increased traction. On the downside, Rivian has shown the R1T having a short bed that's just 4.6 feet long and 4.5 feet wide, and towing the max 11,000 pounds will cut the truck's all-electric driving range in half.
Claims don't mean much or hold that much weight.... Real world is never predictable. And battery is not straight forward as they make it seem.... Just look at what people do with deep charge/starter batteries.... A abused great Northstar AGM TPPL battery won't put out hardly 300 deep cycles... To a depth of 50 percent of discharge... Where one taken great care of can get 1,100 deep cycles to 50 percent of discharge...
No difference between that battery circumstance and the battery running a vehicle... Lots and lots of variables there.
And if one thinks pushing 800 Volts into a battery is helpful to it's longevity... That is very, very, very hard to believe.
