EV Charger Test Adapter
An EV charger test adapter (EVSE simulator) plugs into a Type 2 charger and pretends to be a car, so an installer can switch the charger through its states and run safety tests
EV Charger Test Adapter Overview
Key Specifications
- Function: Simulates an EV so an AC charger can be tested and commissioned
- Connector: Type 2 (all three); Smart EV Chargers unit also tests Type 1 tethered chargers with the included Type 1 to Type 2 adapter
- CP Simulation: Rotary switch for vehicle states, e.g. connected, ready to charge
- Fault Simulation: PE Error and CP Error (Smart EV Chargers unit)
- Cable Simulation: 13A to 63A (Smart EV Chargers unit)
- Phases: Single and three phase; LEDs show live status per phase
- Tester Connection: Works with compatible multifunction testers for RCD and 6mA DC testing
- Safety Standard: IEC 61010 (Smart EV Chargers unit)
- NZ Price: $480 (Smart EV Chargers) to $2,201.33 inc GST (Fluke FEV300/TY2, RS NZ)
How Installers Use One
- • Connect the adapter to the charger socket or tethered plug
- • Press the PE test button first: if it lights, there is voltage on the earth (Smart EV Chargers unit)
- • Step from Position B (connected, not requesting charge) to Position C (ready to charge); the charger should switch its output on
- • Trigger PE Error and CP Error: the charger should stop and show a fault
- • Connect a multifunction tester to run RCD trip-time and DC leakage tests
Benefits
- • Tests a charger without needing a car on site
- • Shows whether the charger responds correctly to earth and pilot faults
- • Gives a multifunction tester access to the charger output for RCD testing
- • Helps installers meet the RCD function-testing rules that apply to new work from 13 November 2026
Considerations
- • A tool for registered electricians, not something EV owners need
- • RCD and DC leakage tests need a separate compatible multifunction tester
- • For chargers without built-in RCD testing, check the tester is on the adapter maker's compatible list
- • Prices vary widely; the Fluke kit at RS NZ was out of stock on 5 November 2026, shipping from 20 November 2026
About EV Charger Test Adapters
An EV charger test adapter, also called an EVSE simulator, plugs into an AC charger and imitates an electric vehicle. A rotary switch steps the charger through the control pilot (CP) states: connected but not requesting charge, then ready to charge, so the installer can see whether the charger switches its output on. LEDs show when voltage is present on each phase, and terminals or 4mm sockets let a multifunction tester connect to the charger's output.
The adapters also simulate faults. The Smart EV Chargers EVSE simulator has a PE test button that lights if voltage is present on the protective earth, plus PE Error and CP Error buttons that should make a working charger stop and enter a fault state. Its cable simulation selects charging cable ratings from 13A to 63A. Used with a compatible multifunction installation tester, such as models from Metrel, Fluke or Megger, it allows RCD and 6mA DC residual current testing.
Testing matters more from 13 November 2026. WorkSafe says new electrical installations where construction begins after 12 November 2026 must comply with AS/NZS 3000:2018 including Amendments 1, 2 and 3. The New Zealand changes to clause 8.3.10 remove the option of testing an RCD only by pressing its integral test button, and require function testing to include trip time, confirmation that the RCD works as intended and protects against electric shock, and, for residual sinusoidal AC and residual pulsating DC, the presence of DC leakage and constant DC where applicable.

EV Charger Testing Advice
A test adapter is a tool for registered electricians, not a part you fit to your car. If you are having a charger installed, ask your electrician how it will be tested. Browse other EV parts or find an EV service centre near you.
