Jeremy - I appreciate your calcs helping us to estimate what the Tesla Semi might be capable of doing. Its estimated range seems high for 900 mWh, based on the Ford Lightning's (1 ton 130 kWh battery) actual observed range when towing a travel trailer (80 miles to 20% charge per The Fast Lane Truck's YouTube site, with the charge kept between 20-80% to allow some backup range and to avoid the delay associated with charging the last 20% from 80-100%). A highway semi won't be taken to 0%, so a 20% minimum in practice, allowing leeway for wind and rain mileage impacts, seems reasonable. Perhaps the Tesla battery can be fast-charged to 100% although actual experience with the Lightning, Rivian and Hummer seems to indicate that after 80% the charge rate is slowed by the charger to protect the battery, leading to generally unacceptable charging delays. But, let's give the Tesla Semi the benefit of the doubt and say it's battery will be operated between 20 and 100%, or 80% of its 900 kWh capacity: 720 kWh. Tesla advertising says it has a 500 mile range, so that would reduce it to a 400 mile range. That range seems unlikely to me.

Is there an expert, non-Tesla review, with the Semi towing a full payload of, say, 45,000 lbs, at the same max weight of a diesel rig over a typical Interstate run, followed by a measured recharge time to 100%? Done in both directions and at maximum allowed Interstate highway speeds of 65-70 mph?

I'm new to your site so apologize if you've already answered this question.

Thanks. -Bob
