New three-phase AC Emulator enhances existing solution for testing EV and EVSE charging standards and interoperability

It is expected that the increasing electrification of vehicles will create significant charging demands on the grid while expanding 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 play importance grid modernisation initiatives across the globe to meet this demand. This further leads to test challenges within EV/EVSE charging and grid-edge applications.

With the launch of the SL1200A Series Scienlab Regenerative 3-Phase AC Emulator, a one-vendor solution has been created that consists of hardware, software, consulting and support services for electric vehicle (EV) and electric vehicle supply equipment (EVSE) charging applications and grid-edge applications

The SL1200A series handles 3-phase AC test needs of up to 1200 voltage alternating current (VAC), from 30 kVA to 630 kVA, without requiring a transformer. Two voltage ranges are available: 600 VAC for low voltage inverter test, as well as EV and EVSE charging test applications, and the 1200 VAC allows for high voltage ride through (HVRT) testing without the need for a large, complex test setup. 

Key Features and Benefits:

  • High-power, 3-phase AC and DC power source integrates with EV/EVSE charging and inverter test solutions for a complete test of devices.
  • DC output (Option SDC) enables a high-power DC charging test, up to 1,000 V DC and 120 kW; eliminating the need and expense for extra equipment. 
  • 100% regenerative (bidirectional) power solution with > 85% efficiency to reduce the cost of test with highly integrated capabilities.
  • Achieve 1200 V line-to-line (L-L) at full specifications without extra equipment to reduce cost, increase performance and save space.

“Keysight’s new SL1200A series extends Keysight’s EV and EVSE charging and grid-edge test portfolio,” said Thomas Goetzl, vice president and general manager of Keysight’s Automotive and Energy Solutions business unit. “Along with the company’s SL1040A and SL1047A Scienlab Charging Discovery System, it provides a complete solution that enables our customers to create real-world charging scenarios with confidence in the ability to meet global standards.”
