  • Patent number: 9428075
    Abstract: Disclosed is a battery charging management system of an automated guided vehicle that travels in an unpiloted manner by using a mounted battery as a driving source, the mounted battery being charged in a charging station, wherein a battery charging controller that monitors a remaining capacity of the mounted battery is mounted on the automated guided vehicle, the battery charging controller starts a charging operation for the mounted battery in the charging station when the remaining capacity of the battery is lower than a predetermined value, and a charging route of the vehicle is cut off when a charging amount of the mounted battery reaches a predetermined capacity during the charging operation.

  • Patent number: 9325192
    Abstract: A battery charging management system for an automated guided vehicle that travels in an unpiloted manner by using a battery as a driving power source and performs a charging operation for the battery using a battery charger provided in a charging station, comprises a charge/discharge monitoring part that monitors a charge/discharge amount of the battery, a charging needlessness threshold voltage setting part that sets a charging needlessness threshold voltage for the battery, and a charging control part that performs the charging operation for the battery using the battery charger when it is determined that a voltage of the battery of the automated guided vehicle arriving at the charging station is lower than the charging needlessness threshold voltage set by the charging needlessness threshold voltage setting part. The charging needlessness threshold voltage setting part is configured to lower the charging needlessness threshold voltage during a particularly set time period.

  • Patent number: 9243903
    Abstract: A wrinkle detection device (100) includes: a light projector (110) which, while moving relative to a layered body (40) formed by stacking electrodes (50) and separators (60), projects slit light onto an outermost one of the separators (60); a camera (120) which shoots a shape of the slit light on the separator (60); and a control unit (130) which calculates a gradient of the separator (60) on the basis of the shot shape of the slit light, and determines the existence of a wrinkle on the basis of the calculated gradient.
