Presentation

Boundary testing electric vehicle supply equipment (EVSE)

Electric vehicle charging station manufacturers face a number of challenges, including connectivity issues, component problems and incompatibility. In this presentation, you will learn how to ensure EVSE product reliability and operability is at its optimum before field issues arise. For example, how to control the EVSE to output multiple connectors at the same time based on specified test conditions, and simulate plugging in at different times to test the equipment’s power-sharing capabilities. This test scenario provides realism and, compared with conventional single-coupler testing, reduces the overall testing time by up to 40%, significantly expanding test capacity.
