Title:
Battery system
Document Type and Number:
Japanese Patent JP6194857
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a battery system in which a plurality of batteries are reliably monitored/controlled by wireless communication.SOLUTION: The battery system includes: a plurality of battery subsystems; and an overall management device for managing the battery subsystems. The battery subsystem includes: a battery module; and an intermediate management device. The battery module includes: one or a plurality of batteries; and a terminal management device for managing states of the batteries. The intermediate management device performs wireless communication with the battery module to manage the battery module. The overall management device transmits, to the intermediate management device, a communication measurement instruction signal including information on a measurement content and measurement timing for a battery and information on communication timing for the wireless communication and a frequency channel hopping pattern used for the wireless communication. On the basis of the communication measurement instruction signal, the intermediate management device transmits, to the terminal management device, a measurement instruction signal including information on a measurement content and measurement timing and information on communication timing between the intermediate management device and the terminal management device and a frequency channel hopping pattern.
