In March 2019 the BBC Shared Data Unit reported a "patchy" network of charging points was discouraging UK drivers from embracing electric cars.
Our analysis found more than a third of local authorities had ten or fewer locations where drivers could plug in their vehicles, with wide variation across the country.
We analysed data from Open Charge Map, a crowd-sourced website of charging locations. Not every location will feature in Open Charge Map, but it aims to be a "reliable single point of reference for charging equipment location information". There is no similar resource from the government.
As part of the story we used the Haversine formula to perform 49 million calculations for each distance (as the crow flies) between each of the 7,000 points, and then store the shortest one.
This piece of content was produced by a regional newspaper reporter working alongside BBC staff.
In a Twitter thread, Peter Sherlock explained why the data was used and how the team worked with that

- The Guardian Money's article ‘Why did it take nine hours to go 130 miles in our new electric Porsche?’ describes problems with the charging network as "as one after another [charging stations] were either out of order, already had a queue or were the slow, older versions that would never be able to provide a fast enough charge in the time."
