Abstract: The present disclosure provides a control device for a secondary battery, and the control device includes a controller configured to correct battery characteristics on an open circuit voltage to a remaining capacity of the secondary battery. In the control device for the secondary battery, the controller acquires data of a plurality of open circuit voltages in the battery characteristics during charging the secondary battery. When the secondary battery is fully charged, the controller corrects the open circuit voltages between respective pairs selected and combined from at least one part of the data of the plurality of open circuit voltages. The controller weighted-averages and corrects full charge capacities, which are calculated by the correction of the open circuit voltages between the respective data pairs, with differences each between respective remaining capacities each corresponding between the respective data pairs.

Abstract: A battery controller used in an electronic device supplied with electric power from a battery pack including a rechargeable battery includes a battery monitor for monitoring remaining battery charge in the rechargeable battery, and a power supply controller. The battery monitor issues an alarm when the remaining battery charge lowers to a threshold or below, and, after that, shuts down upon receiving a shut-down command from the power supply controller. The power supply controller sends the shut-down command to the battery monitor upon receiving the alarm from the battery monitor and determining that the remaining battery charge is equal to or below the threshold.

Abstract: A replacement support apparatus is provided for supporting replacement of a plurality of electronic apparatuses each including a plurality of device components. The replacement support apparatus is provided with: a communication circuit, a storage, a processing circuit, and an output device. The communication circuit receives, from a plurality of existing electronic apparatuses, operation information indicating operation conditions of the device components during operation of the existing electronic apparatuses. The storage stores specifications information indicating specifications of new electronic apparatuses as replacement candidates. The processing circuit statistically aggregates the operation information received from the plurality of existing electronic apparatuses, and selects a new electronic apparatus having specifications enabling operation conditions similar to operation conditions of a predetermined ratio of electronic apparatuses among the existing electronic apparatuses, based on the statistically aggregated operation information and the specifications information. The output device presents information on the selected new electronic apparatus.

Abstract: A method executed by an arithmetic circuit of one or a plurality of computers includes periodically collecting log information from an electronic device, inputting the log information collected before a current clock time from the electronic device to a prediction model, causing the prediction model to predict an abnormal or normal operating state of a recording medium after the current clock time, and transmitting replacement notification information that is based on a prediction result to the electronic device. The prediction model is generated by performing machine learning using, as training data, training log information collected within a predetermined period up to a reference clock time from a plurality of training electronic devices each including a training recording medium, and state information indicating an operating state of the training recording medium determined after the reference clock time.

Abstract: An electronic device charges a battery. The electronic device includes a charging circuit, a power supply controller, and a detector. The charging circuit charges the battery. The power supply controller controls charging of the battery performed by the charging circuit. The detector detects information about a use environment where the electronic device is used. When the power supply controller determines that the use environment for the electronic device is a specific environment based on the information detected by the detector, the power supply controller regulates the charging performed by the charging circuit.
