Patent number: 11881731Abstract: A control system for a battery system is provided. The control system includes a master controller and a slave controller using light-based communication. The master controller includes a light source and a transmission controller controlling the light source, and the slave controller includes a photo-sensitive element, a wake-up circuit, a power supply node, and a receiver circuit. The photo-sensitive element receives the light signals emitted by the light source and, in response to receiving a wake-up light signal, outputs a wake-up signal to the wake-up circuit, and in response to receiving the wake-up signal from the photo-sensitive element, the wake-up circuit connects the receiver circuit to the power supply node or to the photo-sensitive element. When the receiver circuit is connected to the power supply node and the photo-sensitive element, the receiver circuit receives an operation voltage from the power supply node and receives reception signals from the photo-sensitive element.Type: GrantFiled: April 12, 2021Date of Patent: January 23, 2024Assignee: SAMSUNG SDI CO., LTD.Inventors: Maximilian Hofer, Roland Klobasa, Gernot Kraberger
