Document Type and Number:
Japanese Patent JP2023077075
Kind Code:
A
Abstract:
To provide a battery monitoring system, a battery monitoring device, and a battery monitoring method that are able to acquire current information of a battery at an acquisition timing synchronized with the timing of acquisition of voltage information by a battery measuring device.SOLUTION: A battery monitoring system according to an embodiment includes a battery measuring device and a battery monitoring device. The battery measuring device detects voltage information of a battery. The battery monitoring device acquires voltage information from the battery measuring device by means of wireless communication and acquires current information of a current flowing in the battery, from a current sensor. The battery monitoring device includes a control unit and a wireless communication unit. The wireless communication unit performs wireless communication with the battery measuring device for a predetermined period. A control unit outputs a voltage measurement instruction by means of the wireless communication unit and, based on timing of transmission of the voltage measurement instruction to the battery measuring device by the wireless communication unit, acquires the current information in a period for which the battery measuring device acquires the voltage information.SELECTED DRAWING: Figure 1
