Mega charger at 3kwh a min or 2kwh min? 44 seconds to 1 min? Wild guess based on Protera with much worse CD and 1/3 weight and 600khw battery? 1800 kwh if linear? Would be 3 min 20 seconds? Well someone can do a real guess based on 7 kwh locked for semi and operational cost comparison to diesel. Of course car would have to be able to take that charge that quick and robotic cable arm or connector for weight. Also 10000 nm torque is like 7375 ftlbs torque which torque to HP would shows a pattern in locomotived where a 6600 hp locomotive will have 177500 ft lbs torque.
