I just spent 2 weeks driving a Chevy Bolt EV in Canada. That car has a 60kWh battery and real world 400km range. My longest drive was 282km from Port Severn, Ontario to Azilda, Ontario (just west of Sudbury). I was on 85% charge at the start and arrived in Azilda on 23%.
I was able to drive from Ottawa to Sarnia (725km) with just two short charging stops....and could have done with just one charging stop if i was willing to cycle the battery deeply (I wasn't).
With a car like this......you'll have to stop before the car runs out of juice.
I'm looking forward to the Tesla Model 3 or Hydundai Kona more than ever now......range just isn't an issue, nor is battery temperature. I drove to Bolt EV over 800km one day when the ambient temp was 35C. No heating issues at all.
