Keysight introduces test for EV charging and grid edge
Hardware software, consulting and support services for electric vehicle (EV) and EV supply equipment (EVSE) charging applications and grid edge applications have been gathered together by Keysight in its SL1200A series Scienlab Regenerative three-phase AC emulator.
It handles three-phase AC test needs up to 1,200V AC from 30 to 630kVA, without the need for a transformer. Two voltage ranges are available. The 600V AC is for low voltage inverter test, as well as EV and EVSE charging test applications. The 1,200V AC allows for high voltage ride through (HVRT) testing without the need for a large, complex test setup.
The electrification of vehicles is expected to create significant charging demands on the grid, while at the same time expand the opportunity for energy storage through vehicle-to-grid (V2G) power applications. Variable renewable energy (VRE) and distributed energy resources (DERs) in the form of solar, wind and battery storage currently dominate the grid initiatives as companies battle to meet increased demand. Both the evolution and increased complexity of the grid lead to test challenges within EV/EVSE charging and grid edge applications.
The SL1200A series extends Keysight’s EV and EVSE charging and grid-edge test portfolio and is a single solution for customers creating real-world charging scenarios that meet global standards.
For example, its high-power, three-phase AC and DC power source integrates with EV/EVSE charging and inverter test solutions for a complete test of devices. The DC output (Option SDC) enables high power DC charging test, up to 1,000V DC and 120kW, eliminating the need and expense for extra equipment, explained Keysight.
It is 100 per cent regenerative (bidirectional) power with at least 85 per cent efficiency to reduce the cost of test with highly integrated capabilities. In addition, it can achieve 1,200V line-to-line at full specifications without extra equipment, for further reductions in cost, and space requirements, while increasing performance, added Keysight.
