Keysight adds tools to e-mobility charging test portfolio
Tools added by Keysight Technologies to its electric vehicle (EV) and electric vehicle supply equipment (EVSE) charging test portfolio extend the company’s offering for design, emulation, and test 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, vehicle makers and electric charging infrastructure manufacturers are working quickly to design and release new products to the market. Interoperability among e-mobility products is a growing concern for the industry, together with the rising complexity of charging use cases, from fast charging to bi-directional power transfer such as vehicle-to-home.
The expansion of Keysight’s e-mobility charging test portfolio helps EV / EVSE manufacturers tackle these complexities and address the underlying communications protocols used in e-mobility products. The tools are interoperable between EVs and EVSE products through conformance testing and type approvals and focus on the range of communications protocols employed by the Combined Charging System (CCS) standards.
Keysight has introduced the SL1550A EV – EVSE charging communication interface tester (com tester). This integrated test adapter for EV communication controllers (EVCC) or supply equipment communication controllers (SECC) enables 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.
Another tool is the SL1556A CCS charging 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 Keysight’s SL1487A CCS charging protocol trace viewer (CPT), over-the-wire data transfer between EV and EVSE can be analysed to resolve interoperability issues.
There is also the SL156XA EV – EVSE charging test robot series. This is 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) is an automated conformance test tool for CCS charging communication based on ISO 15118 conformance testing standards.
The Smart Charging Emulation (SCE) software is customisable and configurable 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.
Finally, the CCS Charging Protocol Trace (CPT) viewer software application enables decoding of CCS charging protocols. It also supports the DIN 70121, ISO 15118-2/-20 for the vehicle-to-grid communication standard as well as other proprietary messages defined for the hardware abstraction layer.
