CCS2 charger testing

CCS2 EV Charger Testing Equipment and Workflow

A CCS2 test system must match the Combo 2 connection, charger voltage and current, PLC communication scope and planned power path. Define the required DIN SPEC 70121 or ISO 15118 edition, diagnostic evidence and external-load arrangement before selecting a portable tester or integrated laboratory.

Define the test scope

Combo 2 connector and cable ratings
Control-pilot and PLC communication sequence
Requested versus measured DC output
External load, protection and shutdown behavior

Plan the equipment and evidence

  1. STEP 1

    Identify the protocol boundary

    Record charger firmware and the exact DIN SPEC 70121 or ISO 15118 parts and editions required by the project.

  2. STEP 2

    Define the electrical path

    Confirm tester connection limits separately from the external load voltage, current, continuous power and facility requirements.

  3. STEP 3

    Choose portable or integrated equipment

    Use portable equipment for field diagnosis and acceptance, or an integrated platform for repeatable laboratory automation and wider instrumentation.

  4. STEP 4

    Specify retained evidence

    Align PLC messages, pilot state, requested values, charger output and protective responses on one reviewable timeline.

Common questions

Does a CCS2 charger tester include a full-power load?

Not necessarily. Many testers simulate the vehicle interface and connect to a separate compatible load. Confirm both connection and load ratings.

Can connector compatibility prove ISO 15118 coverage?

No. Confirm communication hardware, software, protocol editions and test cases separately from the physical Combo 2 connection.
