3. Features

This 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 electrical safety 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.

Fig.3-1 Examples of connection

Note: This adapter is designed for testing Type 1 EVSE Mode 2 and Mode 3 for AC charging.

Available functions:

● Pre-Test verifies that there is no presence of dangerous voltage at the grounded PE terminal.

CP (Control Pilot) state check varies 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.

• PE (Earth fault) error simulation simulates an interruption of PE conductor (or disconnected state) and confirm 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.
  ● Measuring terminals are available for connection with a measuring instrument (multi-function tester, etc.) to perform various tests.

5. Test procedures

5.1 Connection

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

EVSE

5.2 Pre-Test

After connecting with the EVSE under test, touch the touch pad (4) with a bear finger. Normally, the PE conductor is connected to ground and no 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 phase by 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.

Fig.5-3

1) Set the CP state selector (5) to position “A” (car not connected) and connect 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 and require mechanical ventilation. If the EVSE to be tested doesn’t have ventilation system, charging process may automatically stop. In such a 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) to position C or D.

Table 1: EV state

Vehicle state State description
A Electric	vehicle not connected
B Electric	vehicle connected
C Electric	vehicle connected, ready to charge, ventilation not required
D* Electric	vehicle connected, ready to charge, ventilation required

* Vehicle state D is to simulate EVs with batteries that produce hydrogen or other flammable gases when charged. Therefore, in this state, the operation 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 for charge at vehicle state D.

5.4 CP (Control Pilot) signal error simulation

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.

1) Turn and set the CP state selector (5) to position "C" or "D".

* State “D” simulates EVs which use EVSEs installed indoors and require mechanical ventilation. If the EVSE to be tested doesn’t have ventilation, 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.

5.5 PE (Earth fault) error simulation

With a press of PE ERROR button (7) can simulate the interruption of the PE conductor (or disconnected state).

1) Turn and set the CP state button (5) to position "C" or "D".

* State “D” simulates EVs which use EVSEs installed indoors and require mechanical ventilation. If the EVSE to be tested doesn’t have ventilation, charging process may automatically stop. In such a case, please set the SP state selector to position “C”.

2) Press the PE ERROR button (7) and confirm the charging process is aborted and further charging is prevented.

CP duty cycle Din Max. charging current
8% ≤ Din < 10% 6 A
10% ≤ Din ≤ 85% D	in x 0.6 A
85% < Din ≤ 96% (D	in - 64) x 2.5 A

* Duty cycle indicating that EVSE is not generating charging current.
D_in < 3 % : Charging not allowed.
3% < D_in < 7% : Indicates digital communication will be used.
7% < D_in < 8% : Charging not allowed.
Din > 97% : Charging not allowed.
