5.8 Plug and Charge
The VC-EVCC supports Plug and Charge (PnC) according to ISO 15118. Plug and Charge
provides an automatic authentication and authorization process via TLS-secured charging
communication.

The following preconditions must be fulfilled in order to use Plug and Charge with the VC-
EVCC.
Activation of TLS via UDS
Successful configuration of a TLS certificate via UDS
Activation of Plug and Charge via UDS
Availability of an ISO 15118-compliant Public Key Infrastructure (PKI)
An ISO 15118-compliant PKI contains certain certificates which must be installed on the
VC-EVCC. It is mandatory to install the following certificates/private keys.
PnC Root Certificate
OEM Provisioning Certificate and Private Key
PnC Sub Certificate (at least one Sub Certificate must be installed)
PnC Contract Certificate and Private Key
> Use Case 1: Contract certificate installation via UDS

Installation/Certificate Update)
The VC-EVCC supports both use cases to install the contract certificate. All other
certificates can be installed only via UDS.
Note
Details about the activation of Plug and Charge/TLS and the configuration of
certificates are included in the chapter “UDS communication”.
