The IntLion consortium aims to use power line communication for battery management.

Robert Bosch GmbH is leading a new €4.3 million German research project to use the power circuitry in a lithium-ion battery for the secondary purpose of transmitting data about the health of the individual cells. Dual use of the battery's power circuit would eliminate the need for costly extra data-transmission wiring that has been necessary in Li-ion battery systems used to date, according to Bosch. Germany's Federal Ministry of Education and Research will provide €2.5 million in funding through May 2016 for the project called IntLiIon (Intelligent data bus concepts for Lithium-Ion batteries in electric and hybrid vehicles). Other participants are Pro Design Electronic GmbH, the University of Applied Sciences and Arts Hannover, and the Karlsruhe Institute of Technology. Funding from the Ministry of Education and Research comes as part of the “Energy-efficient and safe electromobility” initiative (STROM 2) within the German federal government's “ICT 2020 - Research for Innovation” program.
