Keysight expands E-Mobility Charging Test Portfolio

04 April 2023 - Keysight Technologies expanded its electric vehicle (EV) and electric vehicle supply equipment (EVSE) charging test portfolio to create an industry-leading toolset of design, emulation, and test solutions for e-mobility. The newly introduced tools complement Keysight's EV / EVSE charging test portfolio with component-level and field testing solutions.

The EV market is experiencing dynamic growth with the number of electric cars expected to reach more than 300 million globally by 2030 according to the International Energy Agency. To meet this demand, automakers and electric charging infrastructure manufacturers are working quickly to design and release new products to the market. However, interoperability among e-mobility products is a growing concern for the industry, as is the rising complexity of charging use cases ranging from fast charging to bidirectional power transfer such as vehicle-to-home.

The expansion of Keysight's e-mobility charging test portfolio helps EV / EVSE manufacturers tackle these complexities with solutions addressing the underlying communications protocols used in e-mobility products. Keysight's new charging test solutions improve interoperability between EVs and EVSE products through conformance testing and type approvals by focusing on the complete range of communications protocols employed by the Combined Charging System (CCS) standards.

Keysight's new e-mobility charging test solutions include:

• SL1550A EV – EVSE Charging Communication Interface Tester (Com Tester) – A fully integrated test adapter for electric vehicle communication controllers (EVCC) or supply equipment communication controllers (SECC) enabling equipment emulation or test case execution to test charging communication and protocols. The Com Tester provides component-level testing for development tests, type approval tests, manufacturing tests (end-of-line), and hardware-in-the-loop tests.
• SL1556A CCS Charging Protocol Tracer (Protocol Tracer) – A portable power line communication (PLC) sniffer enabling seamless observation of the CCS communication channel between EV and EVSE in the lab or in the field through conductive or inductive coupling with the charging cable. When used with the Keysight SL1487A CCS Charging Protocol Trace Viewer (CPT), over-the-wire data transfer between EV and EVSE can be analyzed to resolve interoperability issues.
• SL156XA EV – EVSE Charging Test Robot Series – A test automation process that can be used with the Com Tester to incorporate mechanical actuators to simplify the testing process and enable fully automated testing sequences with hundreds of test cases.
• TTCN-3 Charging Communication Test Automation Software (CCT) – An automated conformance testing solution for CCS charging communication-based on ISO 15118 conformance testing standards that empowers design engineers to prepare for type approvals and certification tests.
• Smart Charging Emulation Software (SCE) – A highly customizable and configurable emulation environment for scenario- and functional-driven EV and EVSE tests based on CCS Basic, CCS Extended, and CCS Advanced profiles supporting DIN 70121, ISO 15118-2/-3, and ISO 15118-20/-3.
• CCS Charging Protocol Trace Viewer (CPT) – A software application that enables decoding of CCS charging protocols and supports the DIN 70121, ISO 15118-2/-20 for vehicle-to-grid communication standard as well as other proprietary messages defined for the hardware abstraction layer.
