Validate the onboard inverter as a grid resource
An EV that exports AC power must do more than reverse the direction of charging. Its onboard inverter must perform the grid-support functions required for the intended connection. QualityLogic helps vehicle and inverter teams plan validation around SAE J3072, the applicable grid-code tests and EV–EVSE communications.
Connect the vehicle’s grid behavior to its communications
SAE J3072 addresses the onboard grid-support inverter system and the communications used to configure and authorize export. Plan the electrical tests and message exchanges together so you can see whether the vehicle applies the required settings and responds as intended.
Build a controllable EVSE side of the test
Define how the test environment will provide configuration, authorization and abnormal communication conditions. Combine the EVSE-side simulation with the grid simulator, appropriate vehicle energy source and measurement equipment needed for the selected tests.
Reuse grid-code testing experience
QualityLogic’s IEEE 1547.1 tools provide a foundation for supported grid-code tests, equipment control, measurement capture and result analysis. Our J3072 IEEE 2030.5 profile support lets your team exercise that communications path. Confirm the selected protocol, test coverage and simulator configuration for your program.
Find regressions before the next product release
Repeat relevant tests after changes to the inverter controls, communication implementation or vehicle software. Keep the device configuration and test-suite version with the results so your team can investigate differences and explain what was tested.
Agree the evidence route with the organizations that accept it
Discuss the applicable J3072 edition, assessment process and grid-interconnection requirements with the test lab and target utility. A successful bench test supports that process; the accepted certification or interconnection route must be established for the intended market.
