‘Talkative batteries’: Battery cells send temperature data through existing terminals, simplifying battery management

A battery that “talks” does not use words—it communicates through data. Researchers at Kiel University have demonstrated how sensors inside a battery cell can transmit measurement data to the outside without the need for additional communication wires. Instead, the system uses the existing power connections as well as the electronics that already control the battery’s charging and discharging process.
