I am with Bill on this one. Fortunately informed by a few years as a logistics manager. For Heavy Goods Vehicles at cruising speed there are two major resistances that need power to maintain speed: Air drag and Rolling resistance. Drag is independent of weight but is typically a quarter of the effect of rolling resistance which is proportional to weight. So heavy batteries will drive up your overall power demands per tonne-km moved. Acceleration is rather a small part of a long distance trucks overall energy needs so can be ignored. Trains are a different story. Rolling resistance is negligible as steel on steel has a very low rolling coefficient, so you can pile on the heavy battery packs with little impact on performance.
Thanks for weighing in. I am surprised that rolling resistance is that much higher than drag, especially after learning that 18-wheeler tires are inflated over 100 PSI. In practice, any transition toward electric trucking will be gradual, with short hauls of lighter cargo in more developed areas converting sooner. Logistics seems like an interesting field. I just started reading The Box.
