Sweet spot speed for longer distances?

Let's say I want to travel 250km in one direction. Two riders start riding with full charge at the same time and charge in between when the battery gets empty.

They want to reach their destination as soon as possible with partial recharges on the way.
Which one will reach their destination faster if they ride at 40km/h, 60km/h or ... what is the sweet spot speed?

One must be aware, that partial charge takes aprox. 120 minutes and that if you travel at 40km/h, you make 80km with one charge and if you travel at 80km/h, you can make 50km and need more recharges.

I did a basic calculation by myself, but I'm interested in your opinion also :-)

Re: Sweet spot speed for longer distances?

My calculation for distance of 250km:

40km/h:
- 80km (120min)
- R (120min)
- 80km (120min)
- R (120min)
- 80km (120min)
- R ( 20min)
- 10km ( 15min)
= 635 minutes

80km/h:
- 50km ( 40min)
- R (120min)
- 50km ( 40min)
- R (120min)
- 50km ( 40min)
- R (120min)
- 50km ( 40min)
- R (120min)
- 50km ( 40min)
= 680 minutes

Option 1 is a bit faster, but it's much more easier and safer to ride out of towns roads at 80km/h than at 40km/h.

If one adds the time and distance margin needed to find working recharging locations, it gets ... worse.

Let's say, that you know the locations of charging spots or that you travel with Honda EU2000i Portable Generator ;-)

I'm very tempted to get one for my longer trips.
