OVERVIEW

Introducing CCU

The CCU is an OpenECU™ Charge Control Unit designed as a standalone EVCC for xEV hybrid and battery electric powertrains, including battery electric and plug-in hybrid vehicles. It provides a compact, dedicated charge controller for vehicles that already have a supervisory ECU or need a drop-in CCS charging solution.

The CCU includes onboard DC fast-charging PLC communication according to ISO 15118 and supports ISO 15118-2 CCS, ISO 15118-20, DIN 70121, and SAE J1772. It is designed to meet ISO 26262 up to ASIL-B functional safety requirements and is developed according to ISO 21434 with integrated HSM support for cybersecurity requirements.
