锂离子电池内的电力线通信允许高保真度传感器数据在电池组内的每个仪表化单元的传感器节点之间传输到外部电池管理系统。在本文中，在各种充电状态下的锂离子电池的变化特性进行测量，分析和比较，以了解其有效性的载波频率为10 MHz至6 GHz的电力线通信系统的通信信道。此外，正交幅度调制（QAM）的使用进行了研究，以确定其有效性作为一个国家的最先进的调制方法相同的载波频率范围。总体结果表明，某些载波频率和QAM阶数可能不适合于原位电池组电力线通信，这是由于电池阻抗随着某些锂离子电池单元的充电状态而变化，这导致误差矢量幅度、误码率和符号误码率的增加。本文还提出了基于实证结果的这些变化特征的影响的建议和趋势。
Power line communication within a lithium-ion battery allows for high fidelity sensor data to be transferred between sensor nodes of each instrumented cell within the battery pack to an external battery management system. In this paper, the changing characteristics of the lithium-ion cell at various states of charge are measured, analysed, and compared to understand their effectiveness on the communication channel of a power line communication system for carrier frequencies of 10 MHz to 6 GHz. Moreover, the use of quadrature amplitude modulation (QAM) is investigated to determine its effectiveness as a state-of-the-art modulation method for the same carrier frequency range. The overall results indicate that certain carrier frequencies and QAM orders may not be suitable for the in situ battery pack power line communication due to changes in battery impedance with certain lithium-ion cell states of charge, which cause an increase in error vector magnitude, bit error ratio, and symbol error ratio. Recommendations and trends on the impact of these changing characteristics based upon empirical results are also presented in this paper.
