随着新能源技术的发展，越来越多的插电式电动汽车（PEV）出现在我们的生活中。在车辆到电网（V2 G）信息交换中，电动汽车接入电网获取信息和采集车辆数据的方式是影响V2 G通信可靠性和实时性的关键因素。车载电力线通信（VPLC）重新使用车载电力电缆作为通信介质，这避免了需要额外的车载通信线路，并优化了车内空间。VPLC被认为是一种更具竞争力的解决方案，可以降低与车辆（尤其是PEV）中安装的电子设备快速增长相关的设计复杂性、重量和成本。然而，有一些因素会影响VPLC，从而破坏可靠性并引入问题。这些挑战之一是VPLC信道噪声，它会降低通信可靠性。为此，本文介绍了一种基于电力线通信的V2 G信息交互系统结构，建立了车载数据采集系统的VPLC信道模型。该模型在Simulink中开发，利用各种车辆噪声模型和二进制频移键控（BFSK）调制;它还通过检查基于BFSK的不同类型的噪声来分析信道特性。仿真结果验证了纯电动汽车常用的BFSK调制解调方式下PLC的可行性，为实际工程中VPLC的实现提供了指导。
With the development of new energy technology, more and more plug-in electric vehicles (PEVs) have appeared in our lives. In vehicle to grid (V2G) information exchange, the method that PEVs use to access the grid for information and vehicular data collection is the key factor that affects the reliability and real-time nature of V2G communication. Vehicular power line communication (VPLC) reuses vehicular power cables as a communication medium, which avoids the need for an additional vehicular communication line and optimizes the in-vehicle space. VPLC is being considered as a more competitive solution to reduce the complexity of design, weight, and cost associated with the rapid growth of electronic devices installed in vehicles, especially for PEVs. Nevertheless, there are factors that impact VPLC in such a way that disrupts reliability and introduces problems. One of these challenges is VPLC channel noise, which can reduce communication reliability. Hence, in this paper, we introduce a V2G information interaction system structure, based on power line communication, to establish a VPLC channel model for the vehicular data collection system. The model is developed in Simulink and leverages various vehicular noise models and binary frequency shift keying (BFSK) modulation; it also analyzes the channel characteristics by examining different types of noise based on BFSK. Our simulation results demonstrate the feasibility of PLC under BFSK modulation and demodulation, often used in PEVs, which could provide guidance to the implementation of VPLC in support of practical engineering.
