Access control system for electric vehicle charging
An access control system for electric vehicle charging is provided that includes an access device, a secure reservation interface, a reservation server and a smartphone application installed on the smartphone. The access device includes a short-range wireless communication module connected to a processor having control of an electric vehicle charger. The secure reservation interface receives a reservation request for a reservation at a given destination. The reservation server receives the reservation request for the destination, issues a reservation certificate, and transmits the reservation certificate from the reservation server to a smartphone. The smartphone application has access to a short range wireless communication setting corresponding to the access device. The access device receives the reservation certificate from the smartphone application based on use by the smartphone application of the short-range wireless communication setting. The processor activates the electric vehicle charger based on at least the receipt of the reservation certificate.
1. An access control system for electric vehicle charging comprising:
