Test EV and EVSE Charging Interfaces

Charging Test Solution

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.

SL1040A Scienlab Charging Discovery System – Portable Series

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 Series helps you to comply with current and future charging standards up to 400 kW to ensure conformance and interoperability.

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.

Highlights

• Automated functional, conformance, interoperability and quality testing for R&D, and endof-line (EOL)

• 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.

Open system architecture

Realistic emulation of EV and EVSE requires standard-compliant emulation of the behavior of each emulated side. The CDS offers a freely-parameterizable state machine that provides the required degree of freedom. Errors can thus be emulated in a controlled environment to examine the response of the DUT in all use cases and failures.

The CDS supports the following charging communication standards:

• AC charging mode according to IEC 61851-1 (PWM)

• AC charging mode according to SAE J1772 (PWM)

• AC charging mode according to GB/T 18487.1 (PWM)
