PLC/HomePlug Green Phy
HomePlug Green Phy for E-Mobility
Communication according to ISO/IEC 15118 / DIN 70121 / SAE J2847/2 is based on HomePlug Green Phy or IEEE1901 standard. Thereby the Power Line Signal is modulated onto the Control Pilot Wire (CP) in the charging cable against protective earth. Because of the fact that the electro vehicle charging cables are short compared with cables in PLC applications in the home over mains/ 230V it is required to reduce the transmit power level of the PLC signal.
This reduction in transmit power level is achieved by using a 1:1:1 signal transformer compared with the 1:5:4 that is typically used in mains applications. In addition transmit power level is further reduced by modifying the configuration file of the Green Phy Chips. As PLC nodes in charging stations are requested to have a different behaviour than the ones in the electro vehicles more modifications of the so called PIB-File (Parameter Information Block File) are required.Samples Contacts News
Homeplug Green Phy for Other Applications
In the area of Smart Grid, Smart Meter and Home Control applications, reliable connections are mandatory. At the same time, user data need to be transmitted securely and encoded. This means that overhead data and with it the whole amount of transmit data often is increased and the data rates of Narrow Band PLC are not enough for time critical applications with many nodes involved. On the other side Broad Band PLC with it´s very high data rates are oversized for these kind of applications and the pretty high power consumption speak against the use of Broad Band PLC as well. HomePlug Green Phy Standard offers a solution to this dilemma.
Less Data Rate at Much Reduced Power Dissipation
HomePlug Green Phy dispenses entirely the subcarrier modulation and communication takes place in QPSK-Mode (Quadrature Phase-Shift Keying) of HomePlug AV only. By dispensing subcarrier modulation, it is not required anymore to characterize the channel. Both result in substantially reduced performance requirements for the integrated processor and with that in much reduced power dissipation.
At the same time the required memory can be reduced and as a result can be integrated into the MAC/PHY chip. Sensitivity can be lowered as well when running the chip in QPSK Modulation mode only compared with 1.024 QAM and so the analogue front end can be integrated as well. Both lead to a simplified system design and finally to a single chip solution. Because of the fact that frequency range, channel spacing as well as forward error correction method remain the same for HomePlug Green Phy equipment compared to HomePlug AV / AV2 / IEEE 1901 all devices are fully interoperable and are able to communicate with each other.
Choose Between ICs, Modules and Evaluation Boards
