Four key EV charger operation checks:
1. Proximity detection operation check. The EVCC300 can check that proximity is detected and also whether, when testing a type 1 connection, that latching detection has worked correctly.
2. Control pilot operation check. Not only can the EVCC300 set CP states to operate the EV charger, the instrument can read the response state of the charger. The codes A, B, C, D, E and F can be set by the EVCC300 and the response of the charger displayed on the instruments color display. The charger PC state is displayed together with the chargers indicated maximum charge current, all to IEC61851-1 requirements.
3. Control pilot signal check. The EVCC300 measures the CP signal Voltage, Frequency and Duty cycle. Repeated measurements will highlight instability in the signal. 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.
4. EV charger output check. The EVCC300 measures the output voltage and frequency of the EV charger when charging in is in progress. When appropriate the EVCC300 also checks for correct L - N supply polarity.
