Megger EVCC300 EV Charger Checker
The Megger EVCC300 introduces a convenient way of checking electric vehicle (EV) charge points. This all-in-one solution checks both the safety and operation of mode 2 and single-phase mode 3 (level 1 and two-phase level 2) EV chargers. The instrument is ideal for fault-finding following manufacture or repair, or as part of a regular maintenance schedule.

    
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 if nuisance tripping of RCD/GFCI is likely to occur
    
Reads control pilot state response from EV Charger to IEC61852-1

Features
Four important safety checks:

1. PE touch pad to check ground connection and hazardous voltages

2. PE resistance (RPE) test to check any exposed metalwork is properly grounded/earthed

3. Touch voltage test to ensure the charger ground/earth does not rise to a hazardous level when charger output is on

4. RCD / GFCI protection check by timing the device tripping speed.
Nuisance charger supply tripping check:

This test helps determine whether the user is likely to experience nuisance tripping. The Megger EVCC300 slowly increases leakage current until the protective device trips to ensure it trips at the correct level.
Four key EV charger operation checks:

1. Proximity detection operation check.

2. Control pilot operation check (States A, B, C, D, E, and F).

3. Control pilot signal check (Voltage, Frequency, and Duty cycle).

4. EV charger output check (Output voltage, frequency, and L-N supply polarity).
