高保真数据的实时通信可以显著提高智能电动交通用电池的性能和安全性。电力线通信(PLC)可由智能仪表单元用于在电池组内联网，以及作为电池电动汽车和智能电网的一部分与外部电池管理系统联网。本文研究了以锂离子电池为通信通道的PLC系统在5%、40%、60%和80%荷电状态(SOC)时的有效性。通过使用高达1024-QAM的正交幅度调制和从10 MHz到200 MHz的载波频率来实现高比特率通信。结果表明，对于256、512和1024-QAM，80%的SoC对特定频率下的通信性能有显著影响。详细分析了电池充电状态对现场PLC系统的影响，并根据实验结果对现场PLC系统的参数提出了建议。
Real-time communication of high-fidelity data can lead to significant improvements of the performance and safety of batteries used in intelligent electric transportation. Power line communication (PLC) may be used by smart instrumented cells to network within a battery pack, as well as with an external battery management system as part of battery electric vehicles and smart grids. This paper studies the effectiveness of a PLC system through a Lithium-ion cell as a communication channel, when it is at 5 %, 40 %, 60 %, and 80 % state of charge (SoC). High bit-rate communication is realised through the use of quadrature amplitude modulation up to 1024-QAM and for carrier frequencies from 10 MHz to 200 MHz. The obtained results illustrate that in particular a SoC of 80 % has a significant impact on the communication performance at specific frequencies for 256, 512, and 1024-QAM. The impact of cell state of charge on an in-situ PLC system is analysed in detail, and recommendations on the parameters of such system based upon experimental results are provided.
