  • Publication number: 20240027870
    Abstract: An optical nonlinearity measurement method according to the present disclosure utilizes photon pair generation through a spontaneous four-wave mixing process, to observe photon pairs using an optical waveguide loaded with a two-dimensional material. Compared with the Z-scan method, the influence of free carriers on nonlinear refractive indexes is only indirect. With a parameter being the length of the attached two-dimensional material in the optical waveguide direction, a theoretical value of the coincidence rate of the photon pairs based on the coupled wave equation is fitted to a measured value of the coincidence rate of the photon pairs. For the coincidence rate of the photon pairs, the theoretical value based on the coupled wave equation is fitted to the measured value in a state reflecting the structure of the optical waveguide loaded with the two-dimensional material, and nonlinear coefficients ?1 and ?2 at that time are obtained.

    Abstract: A deterioration diagnosis apparatus of a battery includes one or more processors. The one or more processors are configured to execute discharging of each of a plurality of cells included in an assembled battery while measuring a voltage of each of the cells, estimate a deterioration degree of each of the cells using voltage data indicating a transition of the voltage of each of the cells from a discharging start voltage to a predetermined discharging end voltage, and end the discharging when voltages of all the cells included in the assembled battery reach the predetermined discharging end voltage. The predetermined discharging end voltage is a cell voltage at which a change degree of the cell voltage per unit discharging amount starts to sharply rise while the cell voltage is dropping due to the discharging.
