19.9 Checking the Operating Statuses of Electric Vehicles at
Charging Stations per IEC 61851 ((PROFITEST MTECH+ &
PROFITEST MXTRA)
A charging station is a facility designed to charge electric vehicles
in accordance with IEC 61851-1, and is equipped with essential
elements including a plug connector, conductor protection, an
RCD, a circuit breaker and a safety communication device (PWM).
Depending on where it’s used, other function modules may be
added, for example for mains connection and metering.
Selecting the Adapter (test box)
Simulation of Operating Statuses per IEC 61851-1 with the MEN-
NEKES Test Box
(Statuses A through E)
The MENNEKES test box is used exclusively to simulate the vari-
ous operating statuses of a fictitious electric vehicle connected to
a charging station. Settings for the simulated operating statuses
can be found in the operating instructions for the test box.
The simulated operating statuses can be saved to as a visual
inspection and documented in the report generating program.
Select the respective status to be checked with the
SECLECT STATUS key at the test instrument.
Status A – charging cable connected to charging point only
• CP signal is activated.
• Voltage between PE and CP is 12 V.
Status B – charging cable connected to charging point and vehicle
• Charging cable is locked into place at the charging point and
the vehicle.
• Vehicle is not yet ready for charging.
• Voltage between PE and CP: +9 V / -12 V
Status C – non-gassing vehicle detected
• Vehicle is ready for charging / power is connected
• Voltage between PE and CP: +6 V / -12 V
Status D – gassing vehicle detected
• Vehicle is ready for charging / power is connected
• Voltage between PE and CP: +3 V / -12 V
Status E – cable is damaged
• Short-circuit between PE and CP
• Charging cable is unlocked at the charging point.
• Voltage between PE and CP is +0 V.
Semi-Automatic Changing of Operating Statuses
As an alternative to manual sta-
tus changing via the parame-
ters menu for the
SECLECT STATUS softkey at the
test instrument, quick and con-
venient switching amongst the
statuses is also possible. The
AUTO status parameter has to
be selected to this end. After
responding to the visual
inspection prompt and saving
the results, automatic switching
to the next status ensues – the
01/05 key display corresponds
to A/E (01 = A, 02 = B, 03 = C, 04 = D, 05 = E).
Status variants can be skipped by pressing the I
N
key at the test
instrument or the test plug.
