CCS2 DC fast charger testing
CCS Protocol Tester for CCS2 DC Fast Charger Testing
By APEX · Published · Updated
A CCS2 DC fast charger test setup must combine the correct Combo 2 interface, control-pilot behavior, PLC communication, charger output measurement and a power-absorption path. Confirm the required ISO 15118 or DIN communication version, maximum voltage and current, load arrangement and evidence format before selecting the tester.
Need equipment for this test scope?
Send the connector, electrical range and required evidence for a configuration review.
Which test system fits your charger?
Start with the charger type and test environment, then confirm the connector, electrical range and included functions.
High-power CCS2 diagnosis
Published CCS2 connection ratings up to 1000 V / 500 A. Confirm the protocol edition, continuous-duty limits and separate load configuration.
Portable CCS2 testing
Compare the portable European DC test platform with your PLC, pilot and electrical-measurement requirements. Confirm included and optional functions.
Laboratory integration
Review the integrated DC R&D platform for repeatable sequences and evidence capture. Confirm the CCS2 interface, protocol modules and power equipment in the quotation.
A tester's connector rating is not the continuous-power rating of the complete test setup. Specify the external load, cooling and facility supply separately.

Define the CCS2 charger and communication scope
Record the charger model, firmware, Combo 2 connector rating and target market before choosing test equipment. CCS2 identifies the physical charging system, but it does not by itself define every communication version, optional function or acceptance limit required by a project.
List whether the work covers basic connection and startup, DIN SPEC 70121 behavior, a specific part and edition of ISO 15118, interoperability diagnosis or a formal conformance program. The tester, PLC module and test cases must support the same protocol scope as the charger under test.
- ✓ Confirm Combo 2 connection and cable rating
- ✓ Name the protocol and edition in scope
- ✓ Record charger firmware and configured options
Separate communication from high-power loading
The vehicle simulator establishes pilot and high-level communication states, while the external load or laboratory power system absorbs charger output. Verify the tester connection limit separately from the load voltage, current, continuous power, cooling and facility requirements.
Plan normal startup, requested-current changes, charging stop and protective shutdown before applying high power. Synchronize protocol messages, pilot state, voltage, current and load demand so a failed sequence can be traced to communication, power conversion or the test setup.
Retain evidence for diagnosis and comparison
Save the charger configuration, tester configuration, message trace, key waveform or measured values and result rule for every test. A communication trace without electrical timing can miss contactor or output behavior, while electrical data without the message sequence can hide the reason for a charger decision.
Start with one known-good reference session and one controlled fault. Review the final completed state and the first divergence between sessions before expanding the campaign to boundary conditions or repeated interoperability tests.
- ✓ Capture PLC messages and pilot state
- ✓ Record synchronized voltage and current
- ✓ Keep a known-good reference session
CCS2 configuration review
Compare the complete setup, not only the tester rating
Send these inputs with a CCS protocol tester enquiry so the quotation can distinguish included functions, options and external equipment.

Review published specifications →Communication coverage
- Specify before quotation
- Charger firmware, DIN or ISO protocol part/edition, required normal and abnormal cases, and any optional functions.
- Evidence to request
- Written hardware/software configuration and a case-coverage list; connector compatibility alone does not establish protocol coverage.
Electrical operating envelope
- Specify before quotation
- Simultaneous voltage/current points, test duration and cooling, not just separate maximum ratings.
- Evidence to request
- Tester, cable and external-load ratings, continuous-duty limits and facility requirements for the proposed combination.
Diagnostic evidence
- Specify before quotation
- Required PLC trace, pilot state and voltage/current timing; identify which measurements must be synchronized.
- Evidence to request
- An approved sample export with channel definitions, timestamps, configuration identity and documented limitations.
Acceptance scope
- Specify before quotation
- Field diagnosis, R&D regression or a defined conformance programme; list the cases that will actually be executed.
- Evidence to request
- Agreed acceptance procedure, result limits, software revision and responsibility for any additional instruments.
Scope note: This is a procurement checklist, not a claim that every model includes all functions. Request an approved sample report; no measured customer result is represented here.
Common questions
Does a CCS2 tester include a full-power load?
Not necessarily. Portable testers commonly simulate the vehicle interface and connect to a separate load. Confirm both the tester connection limit and the external load specification.
Is ISO 15118 testing the same as CCS2 connector testing?
No. The connector and electrical interface are only part of the scope. ISO 15118 testing addresses defined communication behavior and requires compatible communication hardware, software and test cases.
