Introduction

1. Introduction

This user guide details the operational and functional details of the Megger EVCC300 Electric Vehicle Charger
Checker.

Please read this user guide fully before attempting to use the EVCC300.

1.1 Product description

The new EVCC300 represents a new concept in electric vehicle charger checking, providing a simple, all in one
solution. The name simply means: Electric Vehicle Charger Checker 300 = mode 3 chargers.

The compact, ergonomically designed instrument allows the user to quickly ensure a charger is in a safe, working
condition. This could be done prior to putting back into use following maintenance, or simply as a regular health
check to ensure everything is safe and working as it should be.

The EVCC300 is capable of checking both the safety and operation of a mode 2 and single-phase, mode 3 electric
vehicle charger and does it in a simple, easy-to-use manner.

One of the benefits of the new EVCC300 is that it not only sets control pilot conditions to allow other electrical tests
or to observe the charger’s reaction, it can also read the code received from the charger. The control pilot signal (CP)
is then compared with the requirements of IEC 61851-1:2017, without the need for a separate oscilloscope.
This makes the EVCC300 a unique solution to ensuring EV charger safety and reliability.

1.2 Features

The EVCC300 incorporates several grouped safety tests: protective earth integrity, nuisance tripping of an RCD or
GFCI, and connection communication and charging control, as follows:

1. Safety checking tests:

1.1. Protective Earth (PE) touch pad test: To detect faults such as open circuit ground connection, voltage present
on ground connection and other charger supply problems.

1.2. Protective conductor resistance measurement (R

1.3. Touch voltage measurement (inherent part of any RCD / GFCI tests)

1.4. Personal protection check

 RCD / GFCI trip time measurement

2. Nuisance tripping check test:

2.1. RCD / GFCI trip current measurement

3. EV charger operation checking tests:

3.1. Proximity pilot (PP) check

 Indicate connection and latching

3.2. Control pilot (CP) check

Tests

5. Tests

5.1 Introduction

5.1.1 Correct testing sequence

The EVCC300 incorporates effectively four safety tests (1.1 to 1.4 in the list below), one test to determine if nuisance
tripping of an RCD or GFCI is likely to occur (2.1 in the list below) and two operational (charger output enabled) tests
(3.1 to 3.2 in the list below) :

Warning: It is important for safety reasons to apply these tests in the order shown below:

1. Safety checking tests:

1.1. Protective Earth (PE) touch pad test: This test can indicate a number of faults:

 Charger is not earthed / grounded

 Charger earth / ground has live voltage present

 Charger is not able to output a charging voltage

1.2. Protective conductor resistance measurement (R

1.3. Touch voltage measurement (inherent part of any RCD / GFCI tests)

1.4. Personal protection check

 RCD / GFCI trip time measurement

 This includes the DC current trip time as this is essential to ensure the AC current element of the

protection remains functioning.

2. Nuisance tripping check test:

2.1. RCD / GFCI trip current measurement

3. EV charger operation checking tests:

3.1. Proximity pilot (PP) check

3.2. Control pilot (CP) check

 Simulates electric vehicle (EV) control pilot (CP) states (A, B, C, D, E and F)

 Reads back the set state from charger (CP voltage, duty cycle and frequency)

 Displays the current available being communicated to the car

Warning: This sequence is important because it ensures the charger is safe before performing the
operational tests in the charger.

Tests

5.2 Tests, PE (protective earth) touch pad test

5.2.1 Description

This is the first test that should be performed when using the EVCC300 to test a mode 2 or 3 vehicle charger.
During this test the charger is quickly powered up. If there is a ground / earth connection present the instrument will
indicate PROCEED. Should there be no ground / earth connection to the charger, or a voltage present on the ground
/ earth the test will indicate FAULT. This test is done by using a touch pad, in conjunction with a series of voltage
measurements.

Fig 1: Pass screen Fail screen

NOTE: This test is disabled when the mains supply is set to 240 V 2 Ph US. This is because this test will not work on

2 phase 180° supply.

WARNING: The PE contact / touch-pad test is not a bonding test and must not be relied on to check
protective earth integrity. It is an ‘open-circuit’ detect test and will not indicate a high impedance earth
connection.

5.2.2 To perform the test

1. Switch the instrument ON.

2. Ensure the mains supply to the charger is powered up and on.

3. Plug the EVCC300 into the charger outlet, either directly into
a type 2 connector or using the adaptor provided into a type
1 connector.

Find Quality Products Online at: [e-mail]

www.GlobalTestSupply.com

Tests

Ensure the connection method indicated in the top left corner of
the MENU screen is correct.

As a reminder the menu screen connection indicator looks like
this.

In this screen the EVCC300 is set to direct connection. If the red
cross is not present the instrument is set for connection to the
charger via a tethered cable or plug in charging cable.

4. Use the softkeys 1 and 3 (Left and right) to select the “PE
contact” test indicated in black.

5. Press softkey 2 to SELECT the test.

6. Firmly press a finger on the PE contact pad.

7. Press and hold the TEST button while keeping a finger on the
contact pad.

During the test the EVCC300 will apply a charging code to the charger to put it into the charging state. This
is to allow the PE contact test to detect if a ground or earth connection is not present. The EVCC300 will then
measure the voltages between L to N, L to PE and N to PE (referring to the plug connections) to ensure the
voltages correct before progressing to the PE touch pad test. The test conditions for the voltage may be found
in the specification section of this manual.

5.2.3 Interpreting test results

The EVCC300 uses input voltage measurements as well as touch pad to detect EV charger’s PE wiring irregularity.
Hence it is essential for users to place fingers on touch pad when instructed on EVCC300’s screen during each PE test
in order to avoid inaccurate test outcome.

 When incorrect wiring causes PE to be live such as shown below:

 EV charger’s L -> L

 EV charger’s N -> N

 EV charger’s PE -> L

The EVCC300 will not detect this fault unless the user’s finger is on the pad.

 When an EV charger’s Earth is open-circuit such as shown below:

 EV charger’s L -> L

 EV charger’s N -> N

 EV charger’s PE -> Open-circuit ( >600 kΩ)

The EVCC300 will detect this fault

Find Quality Products Online at: [e-mail]

www.GlobalTestSupply.com

 When an EV charger’s Earth is incorrectly wired to main neutral such as shown below:

 EV charger’s L -> L

 EV charger’s N -> N

 EV charger’s PE -> N

Neither the voltage measurements nor the touch pad with detect such fault.

Failure to follow test instructions on screen may result in hazardous PE wiring undetected.

These conditions are applicable to UK 230 V, US 120V 1 Ph and US 208 V 2 ph.

 If the EVCC300 has not detected a problem the instrument will indicate PROCEED. This means it is OK to

proceed to the next tests

Tests

If the EVCC300 detects a problem the instrument will indicate FAULT

Should this occur do not proceed with further testing. The charger should be isolated from the mains supply and a
qualified electrician consulted.

The fault could be caused by a number of issues, but they can be summarised as being in one of these three
categories:

 Charger is not earthed / grounded

 Charger earth / ground connection has a live voltage present

 Charger is not able to output a charging voltage. The EVCC300 will apply a C code to enable charging during

the test.

5.4 Tests, personal protection check

5.4.1 Description

EV chargers will always be protected by a residual current device (RCD) or a ground fault circuit interrupter (GFCI).
Both these devices have the same functions, protecting users from electrocution and preventing fault current causing
a fire. They work by detecting an imbalance in the circuit current, if less current returns from the circuit it must be
flowing to ground. If this ground leakage current becomes large the RCD or GFCI will trip.

Personal protection test on the EVCC300 will apply a calibrated ground / earth leakage current matching the rating

5.5 Nuisance trip check

5.5.1 Description

EV chargers will always be protected by a residual current device (RCD) or a ground fault circuit interrupter (GFCI).
These devices have the same function to protect the user from electrocution or to prevent fault current causing a fire.
They work by detecting an imbalance in the circuit current, if less current returns from the circuit it must be flowing
to to ground. If this ground leakage current becomes too large the RCD or GFCI will trip.

The nuisance tripping test on the EVCC300 will apply a calibrated earth ground leakage current starting at approx
half of the trip rating of the chargers protective RCD or GFCI device selected. The instrument will then increase the
current until the RCD or GFCI trips. The result will be the actual current at which the device tripped, and is displayed
in mA. Should the trip current be low this will indicate a high probability the charger will suffer from nuisance
tripping of the RCD or GFCI.

The EVCC300 can perform four different tests as follows:

230 V Ph to N (UK / Europe tests)

 AC current ramp test

 Test current: Ramp up to 30 mA in 2 mA steps of 300 ms duration

5.6 Tests, Proximitary check

5.6.1 Description

Proximity circuit on the EVSE (Electric Vehicle Service Equipment) connector provides the EV with a signal so it knows
it is connected to a charger. When connected the proximity signal will prevent the EV from moving. When not
connected the voltage on the EV proximity pin will be 4.5 V. Once the charger is connected and the button / lever on
the J1772 type 1 connector resistors in the J1772 connector will cause the voltage to drop to 1.5 V. The EVCC300
tester will check to see if this happens correctly by simulating the circuit in the EV.

In chargers that use separate connecting charging cables, the connector applies a PP resistance signal to the charger
to indicate to the charger the rating of the connection cable being used. The maximum current available indicated to
the vehicle via the CP signal will be adjusted accordingly. The EVCC300 can be used to check this happens correctly
by testing with different rated connecting cables.

5.6.2 How to perform the test

The proximity circuit check is performed as part of the testing for the control pilot. Refer to 5.7.2 How to perform the
test on page 31

5.6.3 Interpreting test results

In the top left of the EVSE interface screen next to “Prox:” two symbols will appear. One of them indicates that
proximity has been correctly detected, and the other indicates if the latch has locked on the type 1 connector.

a. No proximity

b. Proximity detected, not latched

c. Proximity detected and latched

5.7 Tests, Control pilot and charger output check

5.7.1 Description

The control pilot signal is the communication between the charger and the electric vehicle and cover three main areas
of communication.

1. The state of the vehicle / charger

a. Disconnected

b. Connected

c. Charging

2. The Maximum current to be drawn by the vehicle

3. Whether digital communication indicates current

The CP signal uses a 1 kHz square wave signal with the charger state communicated using the signal voltage level.
The maximum current and whether digital communication is in use is indicated by the signal duty cycle.

The EVCC300 takes the place of the vehicle and allows the user to set the desired CP code. The EVCC300 will then
read the code back from the charger as set out in table A8 of IEC61851-1. This allows the user to verify the correct
operation of the charger, ensuring that the charger responded as expected.

In addition, when testing the control pilot signal the EVCC300 will also measure the charger output voltage and
frequency. The EVCC300 will measure the output of single phase chargers, using phase T1 only.

measurement.

13. Re-pressing the TEST key will repeat the test measurements

Repeating the measurements will assist in looking for stability in
voltages etc.

5.7.3 Interpreting test results

Generally the user should check that all of the measured parameters are as expected. The EVCC300 performs a single
measurement of each parameter every time the test button is pressed.

1. The output charging voltages and frequency should be as expected for the type of supply the charger is
connected to.

2. The polarity of the charger should read OK. If the polarity is incorrect the result will be INV.

3. The IMAX read by the EVCC300 should match what the rating of the charger is or the rating of the connecting
cable used.

NOTE: when EVCC300 is plugged directly into a charger the PP resistance applied sets the lead rating to 32A.

4. The control pilot voltage, duty cycle and frequency measurements should be repeatable when the test
is repeated.

5. The CP state read from the charger by the EVCC300 should match the code set for the test. Should the code
measured be different from that set the charger indicates it is faulty.

6. Should the read back control pilot indicate a code “F – Fault” it means that there is a fault or error with the
charger itself.
