The PQA8000H EVSE is a Pelicase-based upgrade kit that transforms the PQA8000H into a self-contained, field-ready measurement system for EV charging station analysis. Everything needed for on-site operation (power supply, current sensors, and auxiliary interfaces) integrates directly into the case, so the instrument arrives at the measurement point ready to connect and measure.
PQA8000H – EVSE
Plug & Play Measurement for EV Charging Station Analysis
Electric Vehicle Supply Equipment
Ready to Deploy at Any Charging Station
The result is a purpose-configured system built on the full measurement capability of the PQA8000H: Class A++ power quality, supraharmonics up to 500 kHz, CP signal analysis, and simultaneous AC/DC measurement — all within a single portable case.
Optional Integrations
The kit can be configured with the following optional integrations:
- Current sensors — Rogowski or Zeroflux transducers, integrated inside the Pelicase
- Power supply CAT IV 230V / 400V for direct on-site operation
- Residual current monitor for leakage current measurement
- CP signal measurement
- Auxiliary sensors and interfaces (CAN, etc.)
- 12V vehicle board system power supply with polarity protection and fuse
- Grid Impedance Analyser
- Virtual vehicle switch for EV charging station tests

The full measurement specifications, hardware options, and software capabilities are documented on the PQA8000H product page.
Grid Impedance Analyzer
The GIA extends the EVSE setup with grid impedance measurement up to 450 kHz for resonance detection, supraharmonic propagation analysis, and PLC assessment.
Electric Vehicle Charging Station: Efficiency and Interference Analysis
EV charging station troubleshooting requires analysis across multiple domains: AC power quality, DC charging parameters, control signal integrity, and electromagnetic compatibility. Problems can originate from grid conditions, charger electronics, vehicle systems, or electromagnetic interference from nearby equipment.
Conventional power quality analyzers cannot address the full scope of charging system analysis. Engineers need measurement capabilities that cover supraharmonic emissions, CP/PP signal analysis, efficiency measurement, and communication protocol verification in a single diagnostic approach.
This application note presents comprehensive EV charging station analysis methodology covering power quality, efficiency, and communication systems. Case studies include charging interruptions caused by supraharmonic emissions at 20-40 kHz switching frequencies.
Explore measurement techniques for CP signal PWM analysis, CAN bus protocol monitoring, and simultaneous AC/DC power measurement for efficiency calculation. The note demonstrates multi-channel synchronized measurements that reveal interactions between charging operations and grid stability.
