TEST ENGINEERING. KNOWLEDGE

How do you test ISO 15118-20 Plug & Charge and bidirectional charging on an EVSE?

Separate protocol negotiation, authentication and energy-transfer control into explicit test cases. Define the supported ISO 15118-20 profile, credential setup and transfer direction, then check both normal sequences and the agreed failure responses.

Test area and evidence

Test areaWhat to define or record
ProtocolIdentify edition, profile and supported services.
AuthenticationDefine valid and invalid credential scenarios.
Power directionAgree source/sink equipment and operating limits.
EvidenceCorrelate messages with electrical behaviour.

Coverage depends on the configured hardware, interfaces, firmware and released test libraries. State the agreed method and normative edition in the result. No blanket certification or universal fault coverage is implied.

Questions about this test scope

What must the test record identify?

Identify the DUT, counterpart, firmware, configured interfaces, method, library version and measured result.

Can one result prove every supported variant?

No. Define which configurations and conditions the executed cases cover, and document any untested boundary.

How do I choose the related test setup?

Start with the DUT role and required interfaces, then agree the communication, electrical and power scope with the application team.
