Publication number: 20230060964Abstract: A power management system includes a photovoltaic power generator connected to a power network, an energy storage device configured to be connected to the power network, and a server. The server is configured to: acquire a predicted value of solar radiation at a prediction time at a point where the photovoltaic power generator is installed; calculate a predicted value of power generated by the photovoltaic power generator at the prediction time by using the predicted value of solar radiation; set a target range of an SOC of the energy storage device by using the predicted value, and control the SOC in such a way that the SOC falls within the target range by the prediction time; and set the target range to a wider range when reliability of the predicted value is low than when the reliability of the predicted value is high.Type: ApplicationFiled: August 11, 2022Publication date: March 2, 2023Applicant: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Tamaki OZAWA, Toru NAKAMURA, Akinori MORISHIMA, Yusuke HORII, Wataru MATSUMURA

Publication number: 20220396171Abstract: A power management system includes a plurality of power adjustment resources electrically connected to a microgrid MG, and a CEMS server that manages the power adjustment resources. The CEMS server outputs a power adjustment request to the power adjustment resources when suppression of power consumption or consumption of surplus power in the microgrid MG is requested, and gives an incentive to a “responding resource” as the power adjustment resource that performs power adjustment in response to the power adjustment request among the power adjustment resources. The CEMS server increases the incentive more as a deviation of a time period during which the power adjustment is performed by the responding resource, with respect to a time period determined in the power adjustment request is smaller.Type: ApplicationFiled: April 25, 2022Publication date: December 15, 2022Applicant: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Tamaki OZAWA, Tohru NAKAMURA, Akinori MORISHIMA, Yusuke HORII, Wataru MATSUMURA

Patent number: 9738266Abstract: An engine controller includes: a warm-up control unit that performs warm-up operation for letting the engine continuously operate until an integration value of air intake of the engine comes to a predetermined integration value in order to warm up a catalyst provided in an exhaust system when the engine is first started after start-up of the vehicle; and a continuation control unit that lets the engine continuously operate for a predetermined period subsequent to an end of the warm-up operation. The continuation control unit takes an output value of the engine as a request output value when the request output value of the engine is a predetermined idling output value or more that is smaller than the predetermined warm-up output value and takes the output value as the warm-up output value when the request output value is less than the predetermined idling output value.Type: GrantFiled: March 25, 2014Date of Patent: August 22, 2017Assignee: MITSUBISHI JIDOSHA KOGYO KABUSHIKI KAISHAInventors: Jun Aizawa, Wataru Matsumura, Shingo Sonoda
