EV Charging and Convenience Retail: Measuring the Commercial Connection

EV charging can create an opportunity for a store visit, but charging time is not a guaranteed retail sale. A driver may stay in the vehicle, arrive after the kitchen closes or choose a competing outlet. Forecourt investment decisions should measure that connection instead of assuming a fixed basket multiplier.

Three services with different responsibilities

Charging operation, retail checkout and roaming should be specified separately. The Open Charge Alliance describes OCPP as communication between charging stations and their management systems. That does not establish a supported connection to every forecourt POS or give a vehicle permission to buy merchandise. Open Charge Point Protocol

Plugsurfing announced on 1 September 2026 that its Roam OCPI service would expand Circle K customers’ access to a network of more than one million European charge points. The announcement concerns charging access, not universal redemption of retail loyalty points. Plugsurfing and Circle K roaming partnership

Analysis: test conversion and contribution

For a pilot, record charging sessions, store visits, purchases and gross contribution by time of day. Use a defined comparison period and account for changes in prices, promotions and traffic. A rise in basket value among purchasers can coexist with a low proportion of charging customers entering the store.

Choose amenities around the intended customer: safe walking routes, clear opening hours, available toilets, food that can be served within the visit and a straightforward return to the vehicle. Treat those as service design choices to test, rather than proven revenue guarantees.

Keep the energy model separate

Estimate electricity purchasing costs, demand charges where applicable, maintenance, payment costs and charger utilisation. Storage may help a constrained site, but its additional cost and operating limits belong in the investment case. The national-laboratory guide explains these trade-offs; it does not supply a universal charging-profit percentage. Battery Energy Storage for Electric Vehicle Charging Stations

Before committing to a combined platform, test customer support, failed authorisations, receipts and refunds across all involved providers. Commercial integration is successful when staff can resolve a real transaction problem—not merely when several services appear on one dashboard.
