Meet the SL1047A Scienlab Charging Discovery System – High-Power Series

The Scienlab Charging Discovery System – High-Power Series from Keysight enables you to test charging interfaces of electric vehicles (EVs) and EV supply equipment (EVSE) during high-power charging up to 1,500 V DC and ±600 A DC. With the CDS can perform all necessary conformance and interoperability tests according to worldwide charging standards. Our new solution, which features the separate Scienlab Cooling Unit with interchangeable liquid-cooled charging adapters, also enables a high-power upgrade of the SL1040A Scienlab Charging Discovery System - Portable Series.

  • Automated functional, conformance, interoperability and quality testing for R&D and end-of-line (EOL) applications
  • Time synchronous measurement and decoding of communication and power signals
  • Scalable and future-proof hardware design according to CharIN e.V. CCS Test System
  • CE, UL, and KC-mark conformance
  • Extensive Test Case Library for automated conformance testing of CCS, CHAdeMO, and GB/T standard

High Performance for all your Applications

The Scienlab Charging Discovery System – High-Power Series provides an all-in-one system that covers all test areas:

  • Provides independent, reproducible test of any EV and EVSE charging interface through real-time emulation of all electrical interfaces of counterpart (including communication signals and energy transfer)
  • Automatically verifies product performance and prototypes (including fault conditions) long before market release
  • Includes real-time man-in-the-middle mode for easy analysis of interoperability issues between EV and EVSE
  • Integrates with custom hardware-in-the-loop (HiL) solutions through open and fully documented remote interface (LAN)

Scienlab Charging Discovery System Family of Solutions

With Scienlab Charging Discovery System – Portable, EMC and High-Power Series, Keysight helps you comply with the relevant charging standards and ensures conformance and interoperability:
