If I go for a 580 kilometers trip, does it make sense to divide it into two parts? For example, I can start the trip at 7am and arrive at a destination approx 300km away at around 11am. This would require 2 fast charges to reach it (also I need the juice for later to continue the trip). Then I could leave the car on parking from 11am to 6pm, and then continue the trip for next 300km approx. I need another 2 fast charges to reach final destination.
So I would have a 7h downtime from driving, would it help cool down the battery? Presumably this is during the Summer so outside temperature would be 30c approx.
So the question is, with the outside temp being 30c, will the battery cool down in 7h of rest? Noticably.
This is what I actually do: I'm going to Austria, and this time Tirol. A little bit further away than Vorarlberg, where I went in the summer. My strategy is as follows.
I would drive the first day approximately 500km, and the second day only 300km. Then the first day I will do 3 quick charges, and perhaps a fourth one if I really can't make it.
By lowering your speed: let's say you drive max 90km/h, and only faster while you have the advantage of going down hill? Then you could perhaps, drive maximum 230km or perhaps even a little more: before needing to quick charge.
But I plan my chargings stops, also according to the availability of quick chargers. So if there isn't a quick charger in 180km, then I prefer to do the first quick charger earlier.
If you don't drive to fast, do your quick charges strategic. For example, I plan the second quick charge at a free IKEA CHAdeMO charger. Being limited at 20kW, so it takes longer. But in the meantime we would eat in the IKEA restaurant, so it doesn't matter. And while it counts as a QC session: it doesn't heat the car up as much, when using a CHAdeMO charger that I have to pay for.
I wouldn't limit myself, going on roadtrips: just because of the limitations of the Nissan Leaf. But yeah on a hot summer day, the battery might overheat more quickly. Sadly this year summer was a lot of rain....
