Publication number: 20240140246Abstract: A method for informing of a battery station (battery replacement facility) includes acquiring information (condition information) about a condition emphasized by a user of an electric vehicle, out of a plurality of conditions for a plurality of battery stations for replacement of a battery (secondary battery) mounted on the electric vehicle. The method for informing of the battery station includes determining at least one battery station, which is recommended to the user out of the plurality of battery stations, by evaluating each of the plurality of battery stations based on the information. The method for informing of the battery station includes notifying the user of information about the at least one battery station.Type: ApplicationFiled: October 11, 2023Publication date: May 2, 2024Applicant: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Soshiro MURATA, Hiroshi UMENO, Takahiro NOMURA, Yuya ONOZUKA

Patent number: 10376839Abstract: It is an object to provide an exhaust gas purification catalyst for a lean burn engine having sufficient NOx purification performance. The exhaust gas purification catalyst for a lean burn engine according to the present invention has a catalyst component including noble metal and ceria supported on a three-dimensional structure. In the whole catalyst, the supported amount of ceria per 1 L of catalyst is 140 to 300 g/L, and in the whole catalyst, is 50 to 98% by mass with respect to the whole coated amount. Furthermore, it is characterized that 50% by mass or more of ceria is included in the same catalyst layer in which noble metal is included, and the amount of noble metal included in the catalyst layer is 0.1% by mass or more with respect to the amount of ceria included in the catalyst layer.Type: GrantFiled: January 19, 2015Date of Patent: August 13, 2019Assignee: UMICORE SHOKUBAI JAPAN CO., LTD.Inventors: Takahiro Umeno, Masaya Hanzawa, Yoshiyuki Hayashi

Patent number: 10226755Abstract: The present invention is to provide a NOx storage reduction catalyst for purifying exhaust gas capable of efficiently removing carbon monoxide (CO), a hydrocarbon (HC), and a nitrogen oxide (NOx), in particular NOx, which are harmful components contained in exhaust gas. The NOx storage reduction catalyst for purifying exhaust gas of the present invention is characterized by being obtained by using a complex oxide of strontium and cerium as a catalytic active component, in which the complex oxide of strontium and cerium adsorbs 1.0 mL or less of oxygen per gram in a 400° C. atmosphere, and sinters a precursor at 300° C. or more.Type: GrantFiled: February 7, 2014Date of Patent: March 12, 2019Assignee: UMICORE SHOKUBAI JAPAN CO., LTD.Inventors: Takahiro Umeno, Masaya Hanzawa, Yoshiyuki Hayashi
