Prove how your AC charger supervises export
Your bidirectional AC EVSE connects a vehicle’s onboard inverter to the grid. UL 1741 SC testing evaluates the EVSE’s role in authorizing and supervising that connection. QualityLogic helps you turn those requirements into a practical validation plan.
Make the charger’s responsibilities testable
Plan checks for the EVSE’s recognition of the vehicle’s declared capability, delivery of required settings, authorization to discharge and response to unauthorized or abnormal export. Include the upstream communications and grid-response functions applicable to the certification scope.
Create the conditions a real vehicle may not provide
A production EV normally tries to behave correctly. Testing the EVSE’s supervision requires controlled conditions that can include missing messages, unexpected behavior and unauthorized export. Define the required vehicle simulation and power equipment with the lab so the test environment can reproduce those conditions.
Follow a request through to the measured response
Record what the upstream system requested, what the EVSE communicated to the vehicle and what happened electrically. This helps your team separate a protocol translation issue from a timing, protection or power-response issue.
Use QualityLogic to define and support the workflow
Build from QualityLogic’s established grid-code test environment and J3072 IEEE 2030.5 profile support. Work with us to identify the available protocol testing, equipment control and analysis functions, and any additional simulation or integration work your SC test plan requires.
Give your program a clearer path to the lab
Agree the test scope and equipment configuration early. Run repeatable development checks, resolve failures and organize the results for the certifying lab. The resulting evidence supports the lab’s evaluation and your team’s readiness decisions.
