That seems broadly sensible and workable. Questions that occur to me are:
Not being familiar with your layout, can a person easily comply while having their expensive e-bike or scooter or its detached battery secured against theft or interference?
Are there power points in parking spaces allocated to individual units so that one can plug in when it is convenient without needing to wait for someone else to get off a shared facility?
Have you checked the capacity of the relevant circuits to handle multiple instances of charging? Multiple e-bikes and scooters that might each only pull 1-2 Amps are probably not an issue but you couldn’t have multiple electric cars each pulling 10A on a circuit with multiple 10A power points behind perhaps one 16A breaker.
