A charging-space app needs to distinguish parking availability from access to a working charger. A reservation may depend on connector type, vehicle access and the way the charging equipment is operated.
Integration with a charger or existing network requires confirmation of supported interfaces and permissions. Customers should see whether they are reserving a space, a charging session or both. A failed or unavailable charger needs an explicit support and refund process.
Pilot one site and test an overstaying vehicle and equipment offline after booking. Avoid promising a particular amount of charge without a validated basis. The app can organise reservations and status information, while the actual charging service depends on the installed equipment and operator arrangements.
