Megger EVCC300 Electric Vehicle Charger Checker

Overview

The Megger EVCC300 is a comprehensive electric vehicle charger checker designed for Mode 3 charging points. It provides an integrated solution for verifying both the safety and operation of Level 1 and two-phase Level 2 EV chargers with SAE J1772 Type 1 and Type 2 connectors. The instrument is ideal for post-manufacture, post-installation, and post-repair checks, as well as routine maintenance and inspection schedules.

Safety Checks

• PE touch pad verification to check ground connection and detect hazardous voltages
• PE resistance (RPE) test to ensure exposed metalwork is properly grounded
• Touch voltage test to verify the charger ground does not rise to hazardous levels during output
• RCD/GFCI protection check to measure device tripping speed and verify operator protection

Operation Checks

• Proximity detection operation check with Type 1 latching detection verification
• Control pilot operation check with codes A, B, C, D, E, and F state testing and charger response reading
• Control pilot signal check measuring voltage, frequency, and duty cycle for signal stability
• EV charger output check including voltage and frequency measurement with L-N supply polarity verification

Key Features

• Nuisance tripping check to assess risk of RCD/GFCI interference
• Color display for clear state indication and diagnostic information
• Automatic leakage current testing to calibrated device trip ratings
• IEC61851-1 compliant operation and safety verification

Applications

• Manufacturing and factory acceptance testing of EV charging equipment
• Installation commissioning and initial safety verification
• Post-service and maintenance inspection of existing chargers
• Routine periodic safety and function verification
