Abstract: A method of manufacturing adhered components includes a process of applying adhesive to application areas on a surface of a first component, a process of placing a second component above the first component, and a process of pressurizing the second component toward the first component. In the pressurization process, the load applied to a pressurizer changes while sequentially undergoing a curvilinear increase period in which the load increases in a curved line as the compression amount of the adhesive increases, and a rapid increase period in which the load increases in a polygonal line with respect to the trajectory of the load in the curvilinear increase period as the compression amount increases. During pressurization by the pressurizer, the load is detected by a load sensor, the rapid increase period is detected based on the detection value of the load sensor, and the pressurization is stopped during the rapid increase period.

Abstract: A voltage control method for a secondary battery includes: calculating a voltage difference between a first voltage value as an initial voltage of the secondary battery and a second voltage value as a voltage of the secondary battery after being charged by constant-current charging during a predetermined time period; calculating an internal resistance of the secondary battery based on the voltage difference and a value of constant current applied in the constant-current charging; calculating an additional voltage based on the internal resistance and a value of constant current applied during voltage control, and calculating a target voltage by adding the additional voltage to a predetermined required voltage; controlling the voltage by charging the secondary battery with constant current until the target voltage is reached; and determining that the secondary battery is defective when the target voltage is not reached within a predetermined permissible time period while the voltage is controlled.
