    摘要： Battery system diagnostic data may be generated at battery node controllers in a battery system. A battery node controller may selectively couple a power bus with a battery node including one or more battery cells. An unsupervised machine learning model may be trained based on the battery system diagnostic data. Outlier values may be determined by applying the machine learning model to the battery node diagnostic data. A battery node may be identified as anomalous based on a comparison of a designated outlier value associated with the designated battery node with the plurality of outlier values. A battery node operation profile controlling operation of the designated battery node may be updated.

    摘要： A battery monitoring method and a battery monitoring device are provided in the embodiments of the present disclosure. The battery monitoring method includes: obtaining a first difference value between a state of charge (SOC) of each of a plurality of cells and an average SOC of the plurality of cells according to first time information; obtaining a second difference value between the SOC of each of the plurality of cells and the average SOC of the plurality of cells according to second time information; determining self-discharge rates of the plurality of cells according to the first difference value and the second difference value; and sending a prompt message when the self-discharge rates meet a preset condition. According to the battery monitoring method provided in the embodiments of the present disclosure, the self-discharge rate of the battery can be monitored, and the safety of usage of the battery is improved.

    摘要： Systems and methods for monitoring and management of an electronic device are discussed here. An authentication request is received from a user for access to an electronically secured compartment of an electronic device. Authentication data is obtained from the user. An authentication request that includes a device identifier for the electronically secured compartment and the authentication data is transmitted to a cloud-based authentication service. Access to the electronically secured compartment is provided upon receipt of an indication of an association between the user and the electronically secured compartment from the cloud-based service provider.

    摘要： 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.
