Autocharge Procedure to authenticate and to authorize a vehicle automatically at a charg-
ing station. The EVCC ID of the vehicle is used as identifier. The Combined Charging
System (CCS) standard is required, since the EVCC ID is exchanged via V2G communica-
tion (DIN 70121 or ISO 15118). The recommended integration with OCPP is described in the
Whitepaper “WhitePaper Identification of Electric Vehicles in Charging Station Management
System via OCPP” published by Vector.
Certificate Authority In cryptography, a certificate authority (CA) is an entity that issues
digital certificates. A CA acts as a trusted third party, which is trusted both by the subject
(owner) of the certificate and by the party relying upon the certificate. A CA is required e.g.
for TLS and PnC Certificates.
Charging Station The term charging station describes a physical system where an EV can
be charged. Each vSECC unit corresponds to one charging station.
CHAdeMO is a DC charging standard for electric vehicles. It enables seamless commu-
nication between the car and the charger via CAN communication. Since the standard was
developed in Japan, it is applied mainly by Japanese and North-American car manufactur-
ers.
Combined Charging System is an open, universal and international charging system for
electric vehicles based on international standards. The CCS combines single-phase with
fast 3-phase AC charging using alternating current of maximum of 43 kW. It also provides
very fast high-power DC charging within a single system. The CCS system includes the con-
nector, the managing of control functions and the charging communication between electric
vehicle and infrastructure over Powerline Communication.
Connector The term connector describes an electrical outlet on a charging station. It is
connected to a single EVSE. An EVSE can have multiple connectors attached to it, e.g. one
CCS and one CHAdeMO compliant outlet. However, an EVSE will always use only one of
its connectors exclusively.
Control Pilot See chapter 2.2.5 for more information.
External Identification Means Any external means that enable the user to identify, authen-
ticate and authorize his contract or the EV for a charging session at the charging station,
e.g. an RFID card.
Electric Vehicle Supply Equipment is defined by its ability to deliver energy to one EV at a
time. A charging station can be connected to one or more EVSEs.
