  • Publication number: 20230222848
    Abstract: An information processing center that is communicable with a vehicle includes: a reception unit configured to receive a state quantity of a battery mounted in the vehicle such as an internal resistance value, a temperature, and a state of charge of the battery from the vehicle; a derivation unit configured to derive estimated resistance information which is data obtained by estimating correspondence between the temperature and the internal resistance value of the battery based on the state quantity received by the reception unit when the internal resistance value received by the reception unit is equal to or greater than a predetermined resistance value; and a determination unit configured to determine whether an abnormality has occurred in the battery based on the estimated resistance information and deterioration resistance information which is data indicating the correspondence between the temperature and the internal resistance value in a deteriorated state of the battery.

  • Patent number: 11383736
    Abstract: A vehicle battery controller includes a sensor configured to acquire information on a subordinate battery configured to back up a main battery during autonomous driving, a DDC provided between the main battery and the subordinate battery, a switching circuit configured to switch a connection state of the subordinate battery between a connection state for manual driving and a connection state for the autonomous driving, and an electronic control unit configured to control charging and discharging of the subordinate battery by controlling the DDC and the switching circuit based on the information acquired by the sensor. The electronic control unit permits the autonomous driving when determination is made, through first battery control, that the subordinate battery can output backup power. The electronic control unit determines whether the subordinate battery can output the backup power by executing second battery control having higher accuracy than that of the first battery control.

  • Patent number: 11351940
    Abstract: A vehicle control device includes a connection switching unit configured to switch the connection state to a state in which a second battery is solely connected to a first load when a voltage of a first battery is determined to be equal to or smaller than a first threshold value in a state in which the first and second batteries are connected to the first load, and after a first time has elapsed from switching to the second state, continue the state while the state of charge of the second battery is equal to or greater than a second threshold value, and switch the connection state to a state in which neither the first battery nor the second battery is connected to the first load when the state of charge of the second battery is smaller than the second threshold value.

  • Patent number: 7195869
    Abstract: Each gene in a group comprising many genes is cloned into an expression vector so that its gene product should be expressed as a fusion protein with a protein emitting self-fluorescence to construct a gene expression library. The gene expression library is introduced into cells of two groups to express the fusion proteins in the cells, and only one cell group is stimulated by a drug or the like. Then, cells in which the fusion proteins are localized in the nuclei or their nuclei are isolated from cells of the two groups, respectively. By comparing these cells, genes coding for proteins that are transported into the nuclei specifically in response to a certain stimulus when the stimulus is applied to the cells are retrieved.
