Inhalt:
The demand of Lithium Ion batteries is increasing because of their energy and power density. For cell monitoring, a Battery Management System (BMS) becomes mandatory to control and monitor the battery states. For sharing the measured information, a dedicated communication channel is necessary. Power Line Communication (PLC) avoids extra cables. The optimal frequency range for PLC on batteries depends strongly on the impedance of the power line. Thus, this paper presents simulations and measurements of the impedance of cells between 100 kHz and 40 MHz. Namely the cylindrical 3.45 Ah Samsung INR18650-35E and the pouch 7.5Ah Kokam SLPB75106100 cell are modelled in Solidworks, simulated in HFSS Ansys and measured with the Bode 100 by Omicron.
