Your plan to travel the Wild Atlantic Way with an electric car sounds great!
I can point you in the direction of an excellent post that has all the information you need when planning such a trip. This post here
(Touring Ireland with an Electric Car) includes links to pages that break down the locations of charging stations on the island of Ireland.
On the subject of electric car trips in Ireland, you may also be interested in this page here
. It highlights a 72-hour electric road trip through Ireland's Ancient East, another region in Ireland.
I hope this information will be of help to you.
