Abstract: A display device whose aspect ratio can be changed is provided. The display device includes a plurality of display units and a plurality of driver circuit units. The plurality of display units each include a light-emitting portion and a connection region. The plurality of driver circuit units each include a driver circuit portion and a connection region. The connection regions of the adjacent units overlap with each other and one shaft passes through the connection regions. The adjacent units are electrically connected to each other with the one shaft.

Abstract: A highly safe power storage system is provided. If n (n is an integer over or equal to three) secondary batteries are used in a vehicle such as an electric vehicle, a circuit configuration is used with which the condition of each secondary battery is monitored using an anomaly detection unit; and if an anomaly such as a micro-short circuit is detected, only the detected anomalous secondary battery is electrically separated from the charging system or the discharging system. At least one microcomputer monitors anomalies in n secondary batteries consecutively, selects the anomalous secondary battery or the detected secondary battery which causes an anomaly, and gives an instruction to bypass the secondary battery with each switch.

Abstract: A method of estimating the state of charge of a secondary battery that has high estimation accuracy even when degradation of the secondary battery progresses is provided. Furthermore, a capacity measurement system of a secondary battery that estimates an SOC with high estimation accuracy in a short time at low cost is provided. When the capacity of a secondary battery can be estimated with high accuracy, an anomaly can also be detected in accordance with the value. A novel method of detecting an anomaly of a secondary battery is provided. In the CCCV charging method, the CC time and the CV time are used as learning parameters to construct a learning model. With this learning model, an estimated capacity value with high accuracy can be obtained with use of two data, which are the CC time and the CV time, or three data, which are the CC time, the CV time, and a charge inception voltage value as the minimum input data.

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.

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.
