Abstract: The cost of hardware and the cost of calculation are reduced in the case where a plurality of assembled batteries are used. The amount of change in the voltage of each battery constituting an assembled battery is sequentially measured with a voltage monitor and abnormality is detected from the correlation between the amounts of changes in the voltages of batteries at the same period. Furthermore, abnormality is detected on the basis of the amounts of changes up to the previous step. Inference is made by a reference parameter acquisition system using an IIR filter or an FIR filter.

Abstract: An anomaly detection system for a secondary battery which detects the remaining capacity of the secondary battery on an electric vehicle, cautions against the secondary battery with anomalous characteristics, stops using the secondary battery, changes the secondary battery, or changes charging conditions of the secondary battery is provided. The anomaly detection system is provided; the system compares a value obtained by estimating internal resistance or SOC of a secondary battery based on the measured value of a current or a voltage of the secondary battery with the use of a nonlinear Kalman filter and a value input to an anomaly detection system (network) of AI to predict a change in the internal resistance; the system regards a case where the difference is large as an anomaly; and the system detects an anomaly.

Abstract: To improve image quality of a full-color organic EL display panel. A partition has a stacked structure formed using different materials. A lower partition has a curved shape, and an upper partition has a flat top surface. An angle formed between a plane surface connecting a lower end of a side surface with an upper end of the side surface of the upper partition and the top surface of the upper partition is less than or equal to 90°. The height of the partition is controlled to be greater than or equal to 0.5 μm and less than or equal to 1.3 μm. With such a structure, a large color organic EL display panel achieves high-definition display.

Abstract: It is difficult to know the remaining amount and the degradation state of a power storage device, and it is also difficult to estimate how long the power storage device can be used. Data obtained through midway discharge and mid-to-full charge is used as the learning data to calculate the degradation state and the capacity. In other words, the learning data includes both a discharge curve of midway discharge and a charge curve of mid-to-full charge, and neural network processing is performed with the use of the learned data.
