Too late to edit the above....
Further research shows the power used was 94% of the capacity. The Audi has a 95 kWh
battery, but is limited to 86 of those to reduce the degradation effect that gets worse when charge or discharge approaches 100% or 0%. The Coco has two 40 kWh batteries, but I didn't locate what the usable capacity was.
How close to empty do you run your fossil fueled tow vehicle before you start to squirm?
The 240 mile trip took a bit over 6 hours, or an average speed of less than 40 mph. Since air resistance is a huge power consumer, and that resistance changes at the square of the change in speed, driving that rig at 60 mph (1.5 times the 40 mph) would consume
battery at 1.5 x 1.5 times the rate. The 156 kWh used to go 240 miles at 40 mph would be used in 107 miles driving at 60 mph. I don't need to stop to eat or go pee every 100 minutes so what do I do while recharging?
The Coco can, if available, use DC fast charging at up to 50 kw rate, meaning the 74 kWh used could be put back in an hour and a half.
The Audi has a DC fast charge rate that peaks at 150 kw, but not right away, and that tapers off as full is approached. Audi claims 45 minutes are needed. Again, if a DC fast charge is available. Alternating current charge locations are more prevalent, but those require the use of on-board A/C to D/C chargers that have inherent conversion losses and power limits due to these transformer's heat production.
