Claim 0:
1. A control system for a battery system, the control system comprising a master controller and a slave controller configured to perform light-based communication with each other,
wherein the master controller comprises a light source and a transmission controller configured to selectively operate the light source to emit light signals,
wherein the slave controller comprises a photo-sensitive element, a wake-up circuit, a power supply node, and a receiver circuit,
wherein the photo-sensitive element is configured to receive the light signals emitted by the light source and, in response to receiving a wake-up light signal, to output a wake-up signal to the wake-up circuit,
wherein, in response to receiving the wake-up signal from the photo-sensitive element, the wake-up circuit is configured to connect the receiver circuit to the power supply node or to the photo-sensitive element, and
wherein, when the receiver circuit is connected to the power supply node and the photo-sensitive element, the receiver circuit is configured to receive an operation voltage from the power supply node and to receive reception signals from the photo-sensitive element.
