After installation, MobilityPlus will arrange for inspection by an independently recognised inspection body to ensure compliance with legal requirements. An appointment for the inspection may take several weeks.
In theory, you can use the charging station as soon as the installation is completed and the charging station is activated. Definitely ask the technician for more information.
Is the charging station offered to you by your employer? Then be sure to check your car policy. With some employers, you can only start using the charging station after a positive inspection.
