The difference between the four scenarios almost never lies in the charging station, but in who owns the electricity and who ends up paying for it. With company charging, money flows back from the employer to the employee, because that employee charges the company car at home. In a business park it flows the other way: you sell your electricity to tenants and visitors and pay off the installation with it.
In a residential building it is about neither profit nor reimbursement, but about clean pass-through via service charges – and about a building connection that copes with ten vehicles without being upgraded. In a hotel, by contrast, charging is a guest service: it has to work without registration and must not create a single minute of extra work at reception.
Technically, the same platform sits under all four: the CPMS portal for management and billing, the app for the people at the charge point, and smart charging for capacity and energy costs. How those blocks work together is on the products page.
