Modern automotive battery management systems (BMS) compete with challenging performance and safety requirements and need to monitor a large amount of battery parameters. In this paper, we propose power line communications (PLC) for high voltage (HV) traction batteries to reduce the BMS wiring effort.
Recently, high voltage (HV) power line communication (PLC) has been proposed as an attractive and innovative communication technique to improve cost efficiency and reduce weight and wiring overhead in the battery system [ 20, 21, 22, 23, 24 ].
High Frequency Model of a Single Battery such as DC/DC converters and motor drives a re being connected to the HV battery. To eling of batteries recently gained increasing attention . However, as most of the re- valid for frequencies from 1 kHz to 300 MHz in . The derived e quivalent electrical specific frequency ba nds.
6. Conclusions Power line communications for HV battery systems is an attractive alternative com-munication technique for BMS data transmission and can pave the way for advanced sin-gle-cell monitoring methods such as electrochemical impedance spectroscopy being im-plemented in future smart cells and smart battery systems.
The results demonstrate that battery PLC is a demanding task due to low access impedances and cell coupling effects, yet transfer characteristics can be improved by optimal impedance matching. PLC for HV BMS not only saves weight and cost, but also improves flexibility in BMS design.
Li-ion battery cells provide a low-ohmic access impedance to PLC devices. In consistence with [ 37 ], the access impedance defines the impedance seen by a PLC modem connected in parallel to a PLC access point, which in our case is a single Li-ion cell as indicated in Figure 2 a.
