MILPITAS, Calif., March 13, 2023 (GLOBE NEWSWIRE) -- Lumissil Microsystems, a division of Integrated Silicon Solution, Inc. (ISSI), NXP® Semiconductors, and CarMedialab have teamed up to develop a complete reference development platform based on the Lumissil Microsystems IS32CG5317 Green PHY and the NXP i.MX 93 applications processor. CarMedialab provides their very latest software stacks for ISO 15118 and OCPP, resulting in a fully integrated solution for ISO 15118 compliant communication between the EV and the charging station. 

IS32CG5317 is a Green PHY modem chip designed with stringent automotive and industrial requirements in mind, from chip design to manufacturing. IS32CG5317 complies with HomePlug Gr​een PHY and ISO/IEC 15118 specifications. The IS32CG5317 brings new capabilities of collecting statistics not available thus far with other products. This product development follows the automotive industry’s standards to meet AEC-Q100 grade 2 specification and is available in industrial grade as well. 

NXP's i.MX 93 family of applications processors provide cost-effective integration and affordable performance for smart, reliable, power-efficient devices requiring graphics, vision, voice control, secure connectivity, intelligent sensing and general-purpose processing. The newly released i.MX 93 family is particularly well positioned for EV Charging when taking advantage of its innovative combination of Arm® Cortex®-A55 application cores and an Arm® Cortex® -M33 MCU core. This allows developers to easily partition, and design applications based on real time behavior and high level functionality.

CarMedialab offers software for Smart Charging that can be integrated easily into the charging point. From electric vehicle to charge point, ISO 15118 helps to charge in a smart manner. Authorization, charge start and stop, exchanges of demand and availability, charging profiles and tariffs are all handled by the stack. In addition, OCPP supports managing charge points, and by that influences charging processes, from charging station to central charge management or cloud. With that, it is possible to set charging schedules, show maximum power over time, start or stop transactions, handle authorization, use metering to bill, or even reserve charge points. In summary, the protocols ISO 15118 and OCPP provide a comprehensive interface to control the power consumption of charging procedures for electric vehicles.

“We deliver a complete reference design to help manufacturers a simple and quick development process based on the most advanced ICs in the market,” said Nadav Katsir VP and GM of the Connectivity unit at Lumissil Microsystems.

“NXP continues bridging the gap between development concepts and real products with innovative platforms, technologies and partnerships. The latest electric vehicle charging reference development platform will enable developers to focus on their application while reducing time to market, risk and cost,” commented Mark Swinburn, Electric Vehicle Charging Vertical Manager at NXP Semiconductors.

“We’re very happy having our software stacks run on the new platforms  NXP i.MX 93 with Lumissil CG5317, which  supports  DIN70121 and ISO 15118 with different energy transfer modes AC, DC, Panto Up, ACD,” said Dimitri Shkadarevich, Head of R&D Smart Charging, CarMedialab GmbH.
