Charging Dwell Time and Store Spending: How to Test the Opportunity
The possibility that charging visitors will spend in the shop is commercially useful. It becomes misleading when a single assumed dwell time or basket multiplier is presented as a fact across all sites.

Distinguish a service idea from a measured result
In his MobilityPlaza opinion piece, Jörg Heilingbrunner argues for better-connected customer journeys and presents in-car services as possibilities whose value depends on acceptance and integration. That is an executive perspective, not a dataset proving retail uplift. Invisible by design
Similarly, the Circle K–Plugsurfing announcement concerns access to charging networks. It does not turn a charging credential into universal permission to purchase food. Plugsurfing and Circle K roaming partnership
Analysis: define a fair comparison
Start with the question you want to answer: are charging customers entering the store, buying more often or contributing more after costs? These are different measures.
Use a defined observation period and a suitable comparison group. Document how charging-related purchases are identified, with appropriate transparency and data handling. Account for promotions, seasonal travel, pricing changes and the availability of the food offer.
Report sample size and variation as well as the average. A small group of high-spending visitors can raise a mean without demonstrating broad customer conversion. Distinguish spending per purchaser from spending per charging session.
Turn findings into an operating decision
Test practical changes such as clearer pedestrian routes, visible opening hours or a food offer suited to the observed visit. Change a limited set of variables so the effect is easier to interpret.
Include the cost of the intervention and any additional workload. If the project needs a link between charging accounts and retail loyalty, specify permission, identity matching, refunds and supplier responsibilities before launch.
Use the results to decide which sites merit expansion. The aim is a repeatable commercial case, not a headline that treats every charging minute as automatic store revenue.
