Testing Charging Technology

Overcoming the challenges of interoperability in e-mobility

One of the decisive factors for the breakthrough of e-mobility is to enable all drivers to charge their electric vehicle (EV) conveniently and safely. This places high demands on the charging interfaces at both sides of the charging adapter – at the charging station and within the vehicle. Alongside to the power itself, error-free communication between the EV and EV supply equipment (EVSE) guarantees a reliable charging process. This requires standard-compliant procedures and compatible technologies. Other factors to consider are the local grid supply, regional climatic conditions, and compatibility with different EVs and EVSEs.

Charging Test Solution

Keysight’s Scienlab Charging Discovery System (CDS) is an all-in-one system that covers all charging test areas from mobile use to comprehensive application in the laboratory and provides independent, reproducible testing of any AC and DC charging interface of EVs and EVSEs through real-time emulation of all electrical interfaces (including communication signals and energy transfer) of the counterpart.

The Scienlab CDS – Portable, EMC, and High-Power Series helps you to comply with current and future charging standards up to 900 kW, to ensure conformance and interoperability.

SL1040A Scienlab Charging Discovery System – Portable and EMC Series

Thanks to its modular and innovative design, the SL1040A Scienlab CDS can be configured to your specific needs and replace multiple real EVs/EVSEs with one test solution to ensure an optimal priceperformance ratio.

The SL1040A Scienlab CDS – EMC Series is intended for use inside an anechoic chamber for immunity and emission tests (conducted or radiated) of electric vehicles and charging infrastructure. Due to the special EMC shielded design and built-in low-noise components, the emission of the CDS – EMC Series is reduced to a minimum level so tests could be performed without undesired test environment interference. Furthermore, it is immune to external electro-magnetic fields and can be placed close to the test object during immunity tests.

SL1047A Scienlab Charging Discovery System – High-Power Series

The Scienlab Charging Discovery System – High-Power Series (CDS HP Series) from Keysight is a modular solution for conformance and interoperability testing of EVs and EVSEs high-power charging interfaces up to 900 kW. The Scienlab Cooling Unit of the CDS HP Series allows the use of liquid cooled charging adapters and thus enables to increase the charging current up to 600 A DC. The CDS HP Series can be ordered with the maximum voltage of 1500 or 1000 V DC.

Highlights of the SL1040A and SL1047A Charging Discovery System:

• Automated functional, conformance, interoperability and quality testing for R&D, end-of-line (EOL) and electromagnetic compatibility (EMC) applications (only CDS – EMC Series)

• 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, certified by CSA Group

• Extensive test case library for automated conformance testing of CCS, CHAdeMO and GB/T standards

Optimum Features for Every Test Requirement

All-in-one

The CDS provides all necessary functions required for the testing of charging infrastructure components. Additional analysis or measurement systems are not necessary. Predefined test sequences enable quick tests. Digital inputs and outputs allow locking of charging inlets as well as triggering of LEDs and other freely-usable I/Os.
