The Challenge
This is the story of a 420 mile road trip between our home in Ilkley, West Yorkshire and our family holiday in St Ives, Cornwall. It’s unexceptional, except that I did it in an electric car — our BMW i3 battery electric vehicle (BEV) which has a working range of about 80–90 miles in the summer. The i3 is a fantastic car, and we love it, but its limited range means that it is generally viewed as a car about town, rather than a long distance workhorse. That being said, I often use it for medium distance drives such as the 170 mile round trip to Liverpool and back that I do most weeks.
However a drive of 400 miles or more is quite a different prospect. I spent quite a lot of time considering alternatives to doing the journey this way. I knew that it would be hard. Considering cost, amount of luggage, time required, and other factors, the best compromise solution turned out to be for me to drive in the i3 and for the family to go by train, plane, and taxi.
The Plan
I needed to make a plan.
There are two types of electric vehicle chargers in this world. Rapid chargers, and all of the others. Rapid chargers can charge my car from zero to 80% in half an hour. The other kinds all take several hours to complete a significant charge. I need to plot a course from here to Cornwall that includes a sequence of rapid chargers that are no more than about 70 miles…
