Abstract
A battery management system includes more than three monitoring devices arranged inside a housing with a battery. The monitoring devices monitor the battery and acquire battery monitoring information. The monitoring devices and a controller that controls the battery voltage perform wireless communication via a communication path from the controller through each of the monitoring devices to the controller. The controller transmits a request signal to a receiving device that is one of the monitoring devices, and receives the battery monitoring information of all the monitoring devices from a transmitting device that is another of the monitoring devices. Another monitoring device is a far device farther in distance from the controller than the receiving device and the transmitting device are. The far device receives the request signal through the receiving device, and transmits the battery monitoring information to the controller through the transmitting device in response to the request signal.
