EnglishThis adapter KEW8601, simulating an EV (Electric Vehicle), can be used
for interfacing the EV charge stations, commonly named EVSE (Electric
Vehicle Service Equipment), and performs operation check and electricalsafety tests of EVSE.
In combination with a Multi-Function tester (not included), this adapter
also allows to carry out various electrical installation safety tests from the
EVSE socket.

Examples of connection

Multi-Function tester

Note: This adapter is designed for testing Type 1 EVSE Mode 2 and Mode
3 for AC charging.
Available functions:● Pre-Testverifies that there is no presence of dangerous voltage at the grounded
PE terminal.
● CP (Control Pilot) state checkvaries Control Pilot signal (resistance between CP-PE) to simulate
various vehicle states (A/B/C/D) for EVSE operation check.
● CP (Control Pilot) signal error simulation
simulates the state that CP signal short-circuited to PE and confirm
that EVSE stops AC power flow.
—4—● PE (Earth fault) error simulation
simulates an interruption of PE conductor (or disconnected state) andconfirm that EVSE stops AC power flow.
● Live LED
indicates voltage of the charge plug of EVSE.
● CP (Control Pilot) signal output terminal
is connected to an oscilloscope to analyze Control Pilot signal.

English● Measuring terminals
are available for connection with a measuring instrument (multi-function
tester, etc.) to perform various tests.

English

5.1 Connection
Connect EVSE connection plug of KEW 8601 to an EVSE to be tested.

Fig.5-1
EVSE

5.2 Pre-Test
After connecting with the EVSE under test, touch the touch pad (4) witha bear finger. Normally, the PE conductor is connected to ground andno voltage to ground exists. If a dangerous high voltage is present at
the PE conductor, Pre-Test warning LED (4) lights up. In such a case,stop further testing immediately and check the wiring connections. (e.g.:
The PE conductor isn't connected to ground or is connected to phaseby mistake.)* Pre-Test must be conducted prior to other tests.
* Touch the touch pad with a bare finger. Do not wear insulated gloves.
Ensure a proper connection to the ground (including your shoes),
otherwise, warning indication with (4) Pre-Test warning LED may not be
reliable.

5.3 CP (Control Pilot) state check
Switch the CP state selector (5) to simulate various vehicle state (A/B/
C/D) and check the behavior of EVSE.

EnglishFig.5-3

1) Set the CP state selector (5) to position A (car not connected) andconnect KEW 8601 to EVSE.
2) Turn and set the CP state selector (5) to position B (car connected).
(The EVSE under test may require payment information.)3) Turn and set the CP state selector (5) to position C or D .
* State D simulates EVs which use EVSEs installed indoors andrequire mechanical ventilation. If the EVSE to be tested doesn t haveventilation system, charging process may automatically stop. In sucha case, please set the SP state selector to position C .
Confirm that EVSE is ready for charging and any of live LEDs light up.
* If the EVSE isn t ready for charging, turn the CP state selector (5) to
A and wait for a few minutes. Then turn the CP state selector (5) toposition C or D.

D*Electric vehicle connected, ready to charge,
ventilation required* Vehicle state D is to simulate EVs with batteries that produce hydrogenor other flammable gases when charged. Therefore, in this state, theoperation of the ventilation system is required in the test process.
Quite few EVSEs have ventilation system since most EVs use lithium-ion
batteries and that don t generate flammable gasses when charged.
Confirm that EVSEs that don t have ventilation system won t be ready forcharge at vehicle state D.

With a press of CP ERROR E button (6) can simulate the behavior of
EVSE where there s a short-circuit between CP and PE conductors.

English1) Turn and set the CP state selector (5) to position C or D .
* State D simulates EVs which use EVSEs installed indoors andrequire mechanical ventilation. If the EVSE to be tested doesn t haveventilation, charging process may automatically stop. In such a case,please set the SP state selector to position C .
2) Press the CP ERROR E button (6) and confirm the charging process
is aborted and further charging is prevented.
