Test systems for e-mobility include Smart Charging Emulation Software

Component level Conformance and Type Approval test capability improve product interoperability

Keysight Technologies has expanded the range of its electric vehicle (EV) and electric vehicle supply equipment (EVSE) charging test products to create a full toolset of design, emulation and test systems for e-mobility. The newly introduced tools add to Keysight’s existing 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, car manufacturers and electric charging infrastructure suppliers 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.

This new set of testing products help EV / EVSE manufacturers tackle these complexities by addressing the underlying communications protocols used in e-mobility products. The charging test products 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. There are a number of products in the range.

EVSE Charging Communication Interface Tester

This is 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. It provides component-level testing for development, type approval and manufacturing tests as well as hardware-in-the-loop tests.

CCS Charging Protocol Tracer

The protocol tracer is 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 CCS Charging Protocol Trace Viewer (CPT), over-the-wire data transfer between EV and EVSE can be analysed to resolve interoperability issues.

EVSE Charging Test Robot

This 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.

Charging Communication Test Automation Software (CCT)

Automated conformance testing for CCS charging communication-based on ISO 15118 that empowers design engineers to prepare for type approvals and certification tests.

Smart Charging Emulation Software (SCE)

This software provides a highly customisable 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.

According to Thomas Goetzl, Vice President and General Manager for Keysight’s Automotive & Energy Solutions, with the introduction of new communications-based charging test systems to Keysight’s an already strong EV / EVSE test portfolio, Keysight is giving the industry the tools it needs to respond to the accelerating e-mobility market.

“Keysight is the only vendor offering a complete turn-key system that can be deployed throughout the tested products lifecycle from R&D to maintenance,” he concludes.
