Megger EVCC300 Offers

Capable of checking mode 2 and single-phase mode 3 (level 1 and two-phase level 2) chargers, this EV charger checker can perform four EV charger safety and operation checks. In addition, this checker increases ground/earth leakage current until the protective device trips to ensure it trips at the correct leakage current level. If the leakage current that trips the device is too low, it will indicate there is an issue with the device or that there is already a high level of leakage present.

Features

Checks mode 2 and single-phase mode 3 (level 1 and two-phase level 2) chargers
Checks chargers with SAE J1772 Type 1 and Type 2 connectors
Performs four EV charger safety checks
Performs four EV charger operation checks
Checks to see if nuisance tripping or RCD/GFCI is likely to occur
Reads control pilot state response from EV charger to IEC61852-1


Four important safety checks

PE touchpad to check ground connection and hazardous voltages
PE resistance (RPE) test to check any exposed metal work is properly grounded/earthed
Touch voltage test to ensure the charger ground/earth does not rise to a hazardous level when charger output is on
RCD/GFCI protection check by timing the device tripping speed. This test causes a calibrated ground/earth leakage current appropriate to the trip rating of the device to flow and time how long it takes for the device to break the supply. If an RCD/GFCI was to take too long to trip it would not protect the charger user from electrocution, so it is an important safety check


Nuisance charger supply tripping check
This test will help determine whether the EV charger user is likely to experience nuisance tripping of the RCD or GFCI. This charger checker slowly increases ground/earth leakage current until the protective device trips to ensure it trips at the correct leakage current level. If the leakage current that trips the device is too low it will indicate either an issue with the device or there is already a high level of leakage present.

Four key EV charger operation checks

Proximity detection operation check: Checks that proximity is detected and also whether, when testing a type 1 connection, that latching detection has worked correctly
Control pilot operation check: Not only can this charger checker set CP states to operate the EV charger, but it can also read the response state of the charger. The codes A, B, C, D, E, and F can be set and the response of the charger is displayed on the instrument's color display. The charger PC state is displayed together with the charger indicated maximum charge current, all to IEC61851-1 requirements
Control pilot signal check: Measures the CP signal voltage, frequency, and duty cycle, and repeated measurements will highlight instability in the signal
EV charger output check: Measures the output voltage and frequency of the EV charger when charging is in progress, and when appropriate it also checks for correct L - N supply polarity


Applications

Safety and operation checks on mode 2 and single-phase mode 3 charge points (level 1 and two-phase level 2 in USA)
Connecting to SAE J1772 type 1 and type 2 charger connectors
Checking charger following installation and repair before hand over to customer
Checking charger as part of a regular maintenance schedule
Checking charger following manufacturing as part of a QA inspection
Fault checking when customer reports charger issues to car dealership/service center
