Patent number: 9035615Abstract: An energy management system has an integration control portion that performs control to charge a storage battery with a power of such an amount that a power consumption including a power supplied by a supply portion is equal to or smaller than a target value indicated by power consumption target information recorded in a recording portion when a power consumption detected by a detection portion is smaller than the target value, and to supply a building with a power with which the storage battery is charged such that the power consumption including the power supplied by the supply portion coincides in amount with a power equal to or smaller than the target value indicated by the power consumption target information recorded in the recording portion when the power consumption detected by the detection portion is larger than the target value.Type: GrantFiled: July 26, 2011Date of Patent: May 19, 2015Assignees: TOYOTA JIDOSHA KABUSHIKI KAISHA, TOYOTA HOUSING CORPORATIONInventors: Hiromi Tonegawa, Tetsuhiro Ishikawa, Shinji Ichikawa, Daisuke Ishii, Katsutoshi Murawaka

Patent number: 9000730Abstract: A user inputs a travel distance after last charging of a storage battery of a vehicle into an input field. A capacity of the storage battery at a current charge starting point in time is estimated from a capacity of the storage battery at a last charge ending point in time stored at the last charging and the input travel distance. The estimated capacity of the storage battery is displayed in a display field. During charging of the storage battery, detecting charge current and voltage to estimate a current capacity of the storage battery during charging, a remaining charging period of time and a distance-to-empty by the current capacity and displaying the estimated current capacity, remaining charging period of time and distance-to-empty in display fields are repeated.Type: GrantFiled: December 14, 2010Date of Patent: April 7, 2015Assignees: Toyota Jidosha Kabushiki Kaisha, Toyota Housing CorporationInventor: Katsutoshi Murawaka

Patent number: 8909390Abstract: A charging start time and preliminary air conditioning time are calculated based on the departure time that is set with a control/operation device (S108), and the charging time and preliminary air conditioning time are set (S110). Then, a control is executed to start charging when at the charging start time (S112 to 116) and preliminary air conditioning may be started when the amount of charge is sufficient for preliminary air conditioning and a preliminary air conditioning starting trigger is detected, that is locking or preparation for leaving house is detected, for example (S118 to 128).Type: GrantFiled: June 29, 2011Date of Patent: December 9, 2014Assignees: Toyota Jidosha Kabushiki Kaisha, Denso CorporationInventors: Hiromi Tonegawa, Katsutoshi Murawaka, Tetsuhiro Ishikawa, Shinji Ichikawa, Daisuke Ishii

Publication number: 20130169233Abstract: Use start date-and-time is input by use of U1. Times T1 and T2 to achieve SOC 1 and SOC 2 are set. Charging is started at T2 and is continued until it is determined that SOC 2 is achieved. Thereafter, charging is started at T1 and continued until it is determined that SOC 1 is achieved by the input use start date-and-time.Type: ApplicationFiled: August 4, 2011Publication date: July 4, 2013Applicants: TOYOTA JIDOSHA KABUSHIKI KAISHA, TOYOTA HOUSING CORPORATION, DENSO CORPORATIONInventors: Hiromi Tonegawa, Tetsuhiro Ishikawa, Shinji Ichikawa, Daisuke Ishii, Katsutoshi Murawaka
