🚛 Electric Heavy Truck Lab: Payload, Range, Hills and Regeneration

Long-haul battery-electric truck physics with a generic Blender-modelled tractor-trailer, battery cutaway, megawatt-class charger and a 400 km editable route: road load, the payload-versus-battery weight budget (the payload-range curve), regeneration on descents, charging during the mandatory 45-minute driver break, an optimal-battery-size search and an order-of-magnitude diesel comparison. Inspired by publicly reported electric tractor-trailers; unlike the car range and EV-versus-petrol pages it is about freight, weight limits and logistics.
