Plug&Charge
Plug&Charge refers to the automatic authentica-
tion of a vehicle when the charging cable is
plugged into an intelligent charging station.
An electronic certificate is stored in the PLGW for
this purpose. This means that the customer does
not require any additional authentication via PIN,
RFID card etc.
When the vehicle is connected to an intelligent
charging station, the vehicle is recognised and
invoicing by the power supplier takes place auto-
matically.
The owner of the vehicle receives the electronic
certificate (Plug&Charge certificate) from their
power supply when the contract is signed.
There are two ways of installing the certificate in
the vehicle:
• Via the smart Vehicle Homepage
(connected services)
• Via diagnosis service in the workshop: the
vehicle owner brings the Plug&Charge
certificate + personal password to the
workshop on a USB stick. After the customer
enters the password, the file is decrypted with
the certificate. The certificate is then
installed via Star Diagnosis by a service
employee.

Two other electronic certificates are installed in
the vehicle ex factory:
• Root certificate
• Provisioning certificate
The certificates can be updated in the workshop
using Star Diagnosis if they become invalid or
require an update.
The root certificate applies across different
power suppliers and is required in order to check
a public charging station for "authenticity". This
prevents communication with unauthorised part-
ners.
The vehicle-specific provisioning certificate
contains an individual identification number
(PCID). The vehicle owner needs this PCID in
order to be able to conclude a Plug&Charge power
supply contract. It is handed out to the customer
when the vehicle is handed over.
If necessary, the workshop can print out this PCID
for the customer at any time (e.g. in the event of
loss or change of owner).
i Note
Before installing the Plug&Charge certificate, it
is necessary to ensure that the Plug&Charge
certificate file has been decrypted by the
customer with their password.
