It is from Harding Loevner, using Circle K (owned by Alimentation Couche-Tarde) in Norway (which has electrified faster than other countries) as their case study.
Positives – charging takes a lot longer = higher conversion to spending customer + longer in store.
“About 15% of gasoline customers venture inside to make additional purchases during their car’s few minutes at a Circle K pump, while 40% of EV drivers do so during the 20–30 minutes their vehicle is charging.“
Negatives – three quarters of charging is done at home.
