Patent number: 10170807Abstract: A secondary battery cooling system includes a temperature sensor for detecting a temperature of a battery, an electrically operated cooling fan, and a control unit. The control unit determines whether or not cooling of the battery is necessary based on the battery temperature detected by the temperature sensor and a heat value of the battery estimated when an ignition switch is turned off, and, if the battery temperature is lower than a predetermined temperature and the estimated battery heat value exceeds a predetermined value in the determination, extends a length of time from the determination to a start of driving of the electrically operated cooling fan compared to when the heat value does not exceed the predetermined value, and cools the battery while the ignition switch of the vehicle is turned off. The battery can be thus cooled efficiently while charge and discharge is suspended.Type: GrantFiled: February 8, 2016Date of Patent: January 1, 2019Assignee: TOYOTA JIDOSHA KABUSHIKI KAISHAInventor: Takuro Kikuchi

Patent number: 9862246Abstract: An air conditioning control device of a vehicle in which an air conditioner for adjusting a temperature in a cabin is mounted is provided. The air conditioning control device includes a setting portion, a detector, and an electronic control unit. The setting portion is configured to set an execution schedule of pre-air conditioning that the air conditioner is actuated before a user gets in a vehicle. The detector is configured to detect boarding on the vehicle. The electronic control unit is configured to actuate the air conditioner in accordance with the set execution schedule of the pre-air conditioning, and is also configured to notify the user about execution of the pre-air conditioning when the boarding of the user on the vehicle is detected after the air conditioner is actuated in accordance with the set execution schedule of the pre-air conditioning.Type: GrantFiled: August 11, 2014Date of Patent: January 9, 2018Assignee: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Takuro Kikuchi, Yoshihiro Nomura

Patent number: 9634498Abstract: An electrical storage system includes electrical storage elements connected in series with each other and being charged or discharged; discharge circuits respectively connected in parallel with the electrical storage elements and discharging the corresponding electrical storage elements; and a controller controlling operations of the discharge circuits. The controller calculates a first SOC difference using a full charge capacity of each electrical storage element. The first SOC difference is a difference in SOC between the electrical storage elements and arises due to a difference in full charge capacity between the electrical storage elements. The controller calculates a second SOC difference that is a difference in SOC between the electrical storage elements at the moment the second SOC difference is calculated.Type: GrantFiled: August 6, 2013Date of Patent: April 25, 2017Assignee: TOYOTA JIDOSHA KABUSHIKI KAISHAInventor: Takuro Kikuchi

Patent number: 9365129Abstract: A motor generates a kinetic energy for use in running of a vehicle. An electric storage apparatus is charged and discharged and outputs a driving electric power for the motor through the discharge. A display displays a cruising distance over which the vehicle can be run with the motor. A controller calculates the cruising distance based on a full charge capacity of the electric storage apparatus and displays the cruising distance on the display. When the full charge capacity at a present time is smaller than the full charge capacity at a past time and the electric storage apparatus is not discharged, or when the full charge capacity at the present time is larger than the full charge capacity at the past time and the electric storage apparatus is not charged, the controller displays the cruising distance based on the full charge capacity at the past time on the display.Type: GrantFiled: April 20, 2012Date of Patent: June 14, 2016Assignee: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Takuro Kikuchi, Koji Aridome, Junta Izumi
