Publication number: 20220069370Abstract: An ECU calculates a surface potential of a negative electrode active material relative to a lithium reference potential, according to a battery model for calculating lithium concentration distribution inside the negative electrode active material. The ECU calculates a voltage drop amount associated with charging of a battery, using a charging current to the battery and a reaction resistance, and calculates a negative electrode potential by subtracting the voltage drop amount from the surface potential. The ECU corrects the negative electrode potential, using an SOC of the battery, an average current in a charging period of the battery, and an integrated current in the charging period.Type: ApplicationFiled: November 11, 2021Publication date: March 3, 2022Applicant: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Motoyuki Oniki, Takashi Ogura, Risa Atarashi

Patent number: 9142166Abstract: Provided is a liquid crystal display device capable of improving motion blur and preventing excessive current flow into a light source with a desired balance in a structure where the light intensity of a backlight device is properly changed in conjunction with the ambient illuminance. If the ambient illuminance (S1) of a liquid crystal display device is lower than a preliminarily set predetermined illuminance, a backlight scanning process (intermittent lighting process) is implemented (Yes of S2, S3), while if the ambient illuminance is not lower than the predetermined illuminance, the backlight scanning process (intermittent lighting process) is terminated (No of S2, S21).Type: GrantFiled: March 30, 2011Date of Patent: September 22, 2015Assignee: SHARP KABUSHIKI KAISHAInventor: Motoyuki Oniki

Patent number: 8797253Abstract: In an LCD device, picture quality luminance is controlled through the combination of pulse-width modulation (PWM) system and current value control system, reducing the electrical power consumption associated with turning on an LED. In the LED backlight, the light emitting luminance of the LED is controlled by both PWM and also by current value control, which selects the value of the current supplied to the LED from a plurality of set values. At least one of the plurality of set values is a predetermined current value at which duty reaches a maximum value at the maximum luminance value used in a specified picture quality mode of the picture quality modes established in the liquid crystal display device. In the aforementioned specified picture quality mode, the greatest luminance value to be used is smaller than at least the greatest luminance value used in other specified picture quality modes.Type: GrantFiled: July 6, 2010Date of Patent: August 5, 2014Assignee: Sharp Kabushiki KaishaInventors: Kohji Iwasaki, Motoyuki Oniki
