SL1047A-HP4 Scienlab Charging Discovery System – High-Power Series

The Keysight SL1047A‑HP4 Scienlab Charging Discovery System – High‑Power Series (CDS HP Series) represents the second generation of Keysight’s high‑performance platform for validating state‑of‑the‑art fast‑charging technologies. Designed to meet the rapidly evolving demands of e-mobility, the CDS HP Series delivers exceptional power capability, forward‑looking architecture, and robust test automation to accelerate development, validation, and certification of both Electric Vehicles (EVs) and Electric Vehicle Supply Equipment (EVSE). Supporting charging power levels up to 1,200 kW, the SL1047A‑HP4 empowers engineers to qualify the next generation of fast charging solutions with accuracy and confidence.

At the core of the CDS HP Series is its comprehensive support for major global charging standards and communication protocols. The system enables complete conformance, interoperability, and functional testing across CCS (Type 1, Type 2, NACS), GB/T, and CHAdeMO technologies. This makes it a single, unified platform capable of covering regional differences in charging infrastructure and ensuring seamless EV–EVSE communication worldwide. For detailed, version‑specific compatibility, related data sheets for the Keysight SL2000A, SL1470A, SL1471A, and SL1300A outline the full range of supported charging standards and profiles.

The SL1047A‑HP4 is certified as CharIN Conformance Test System (CCTS) for both Basic and Extended application profiles. This certification underscores its qualification to support recognized industry processes for CCS‑based conformance and interoperability testing. For OEMs, Tier 1 suppliers, and test labs, this ensures alignment with globally accepted validation workflows, critical for consistent EV and EVSE performance across diverse market environments.

A major advantage of the CDS HP Series is its modular, future‑proof architecture. Users can start with a baseline configuration of 400 A and 1,000 V DC and expand system capabilities as test requirements grow. Voltage options scale between 1,000 V and 1,500 V DC, while current levels are upgradable to 400 A, 600 A, or 800 A DC. Importantly, all upgrades can be performed in the field, without returning hardware to the manufacturer, maximizing system availability and reducing operational downtime. This design approach ensures long‑term usability and reduces lifecycle costs as high‑power charging standards continue to evolve.

The CDS HP Series combines precision measurement, reliable operation, and advanced control interfaces to deliver reproducible test conditions across a wide spectrum of scenarios, from functional evaluations and communication debugging to high‑power performance analysis and failure‑mode testing. These capabilities help shorten development cycles and ensure robust EV/EVSE behavior under real‑world charging conditions. For organizations focused on bringing fast‑charging innovations to market, the SL1047A‑HP4 provides an essential toolset for validating hardware, communication stacks, and system integration in a controlled, standards‑compliant environment.

Beyond the high‑power platform, Keysight offers a complete portfolio of CDS variants tailored to specific application needs. These include EMC‑shielded systems for testing in environments with strict electromagnetic requirements, portable units for mobile test scenarios, and megawatt‑level solutions for heavy duty vehicles. Each variant is described in detail in its respective data sheet, available through Keysight’s charging test equipment and solutions portfolio.

With its blend of scalability, certification compliance, global standards coverage, and high‑power capability, the Keysight SL1047A‑HP4 CDS HP Series provides a reliable, future‑ready foundation for advancing EV charging technology. Whether supporting R&D, conformance certification, interoperability programs, or end‑of‑line testing, the system empowers developers and manufacturers to deliver safe, efficient, and standards‑aligned fast‑charging solutions for today’s and tomorrow’s e-mobility landscape.
