    Abstract: A battery management system includes a monitoring device and a control device. The control device transmits request data requesting transmission of battery information, and the monitoring device transmits response data including the battery information to the control device. The control device makes next request data include communication establishment information and transmits the next request data. The monitoring device includes a transmission buffer capable of individually accumulating the battery information for multiple times. The monitoring device deletes the battery information corresponding to communication establishment from the transmission buffer, and holds the battery information corresponding to communication failure in the transmission buffer based on the communication establishment information.

    Abstract: A battery monitoring system includes battery measuring devices and a battery monitoring device. Each of the battery measuring devices detects voltage information on a corresponding battery. The battery monitoring device is configured to: acquire the voltage information from each of the battery measuring devices by using wireless communication; and acquire current information on current flowing through the corresponding battery from an electric-current sensor. The battery monitoring device includes a control unit and a wireless communication unit. The wireless communication unit executes wireless communication with the battery measuring devices with a predetermined period. The control unit is configured to: cause the wireless communication unit to output a voltage measuring instruction; and based on a timing at which the wireless communication unit transmits the voltage measuring instruction to the battery measuring device, acquire the current information during a time interval in which the battery measuring device acquires voltage information.

    Abstract: A battery management system includes multiple monitoring devices and a control device. The monitoring devices are disposed in a housing that accommodates a battery of a vehicle and monitors battery information indicating a state of the battery. The control device performs wireless communication with each of the monitoring devices and acquires data including the battery information to execute a predetermined process. The control device sets a cycle in which the multiple monitoring devices make a round in order to perform wireless communication with each of the monitoring devices, and is capable of adjusting the cycle.

    Abstract: A voltage monitoring device has a capacitor circuit having capacitors connected in series, first switches connecting end terminals of the capacitor circuit to specific electrode terminals of unit cells in a battery pack, second switches connecting remaining electrode terminals of the unit cells to the connection nodes between the capacitors, first voltage detection sections corresponding to each of the capacitors, a second voltage detection section connected to the end terminals of the capacitor circuit, and a microcomputer which selectively performs a first process of charging each capacitor, and a second process of charging the capacitors simultaneously. The respective specific electrode terminals correspond to the unit cells, and are arranged at an interval corresponding to the number of connection nodes formed between the capacitors. The microcomputer performs a polarity switching process of adjusting for the adjacent capacitors to have a same polarity of the charged voltage before performing the second process.

    Abstract: A battery management system in a vehicle includes: monitoring devices arranged in a housing accommodating battery; and a control device arranged in the housing, acquiring battery information from the monitoring devices, and performing a predetermined process. The control device stores, in advance as learning data, data that correlates with an electric field intensity in the housing for frequency channels that are usable to transmit and receive data to and from each of the monitoring devices performing wireless communication. The control device determines a target frequency channel of the frequency channel hopping based on the learning data.

    Abstract: A battery management system includes monitoring devices arranged in a housing that houses batteries and a control device. The monitoring device includes (i) a monitoring IC capable of acquiring battery information and (ii) a wireless IC. At a start-up time of the plurality of monitoring devices, each of the wireless ICs performs an advertising operation in a cyclic advertising event for establishing a connection of wireless communication between the plurality of monitoring devices and the control device, and the control device performs a scan operation. The wireless IC of each of the two or more monitoring devices has, respectively, an event management unit that manages a generation cycle of the adverting event, for performing the advertising operation at respectively different timings.
