Description
CC Com Module is intended to add full IEC 61851 and ISO 15118 functionality to any existing AC and DC charging stations or provide this functionality to pure DC charging stations as well as to existing Combined Charging Systems (CCS) to bring down system cost. The module contains a coupling transformer with a 1:1:1 winding ratio, zero-cross (ZC) analog and digital inputs, and a PWM control pilot generation circuit. CCcom module provides the necessary hardware to support ISO 15118 HomePlug GreenPHY power-line communication over the Control Pilot (CP) wire and Protective Earth (PE). The module includes NXP MCXN947VNLT MCU for executing the ISO/IEC 15118 / DIN 70121 software stack on it, using Ethernet and SPI or UART as Host Control interfaces as well as Control Pilot for PLC communication. In addition, the CC com module provides IEC 61851-1 / SAE J1772 PWM generation and detection functionality on the EVSE side. CC Com module is based on the Qualcomm QCA7005-AL33 HomePlug Green PHY automotive IC and together with its TCXO generator it makes possible operation temperatures up to +105°C.
