Patent number: 11749854Abstract: In a battery cooling structure for a vehicle, a battery including a plurality of cell groups arrayed in a vehicle body front-and-rear direction. Each cell group includes a plurality of cuboid cells that are arrayed in a thickness direction of the cells. Each cell includes a positive terminal provided at one side wall extending in a short side direction of the cell and a negative terminal provided at another side wall extending in the short side direction. The positive terminals of one of the cell groups and the negative terminals of another of the cell groups, which cell groups are adjacent in the vehicle body front-and-rear direction, oppose one another in plan view.Type: GrantFiled: November 16, 2020Date of Patent: September 5, 2023Assignee: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Kenichi Ichinose, Masayuki Yoshikawa, Hiroyuki Nishimura, Kazuhisa Ori, Hidetoshi Katoh

Patent number: 11677340Abstract: A motor drive device that includes: a power control unit that drives a motor, which configures a motive power source of a moving body, by supplying a drive signal modulated according to a carrier frequency; a memory; and a processor that is coupled to the memory, the processor being configured to: predict torque demand on the motor, and change the carrier frequency of the power control unit in a case in which an increase in the torque demand on the motor has been predicted.Type: GrantFiled: November 5, 2020Date of Patent: June 13, 2023Assignee: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Hidetoshi Katoh, Masayuki Yoshikawa, Kenichi Ichinose, Hiroyuki Nishimura, Kazuhisa Ori

Patent number: 11670820Abstract: A battery mounting structure of a vehicle includes a battery case, a cable and a shielding member. The battery case includes a lower case and an upper case. In each of plural battery cell groups, plural battery cells are arrayed in a first direction. The battery cell groups are accommodated in the battery case in a state in which the battery cell groups are arrayed along a second direction, which is orthogonal to the first direction in plan view. The cable is routed at an upper face side of the battery cell groups so as to connect the battery cells in series. The shielding member is configured by a conductor so as to form an electrical loop, and is provided at the upper case so as to be overlapped with at least a portion of the cable in plan view.Type: GrantFiled: December 8, 2020Date of Patent: June 6, 2023Assignee: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Masayuki Yoshikawa, Kenichi Ichinose, Hiroyuki Nishimura, Hidetoshi Katoh, Kazuhisa Ori

Patent number: 11585875Abstract: A magnetic field measurement device measures a magnetic flux density vector or a magnetic field vector generated from each of segments obtained by segmenting a measurement target surface of a vehicle. A magnetic field evaluation device includes a propagation intensity calculation unit and a display control unit. The propagation intensity calculation unit calculates propagation intensity that is the intensity of a magnetic field or the magnitude of magnetic flux density that propagates from each of the segments to an evaluation point that is separated from the measurement target surface with use of the magnetic flux density vector or the magnetic field vector in each of the segments and a separation distance between the segments and the evaluation point. A display control unit displays on a display unit a propagation intensity distribution image indicating the position of the evaluation point and distribution of the propagation intensity in each of the segments.Type: GrantFiled: February 7, 2022Date of Patent: February 21, 2023Assignee: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Masayuki Yoshikawa, Hiroyuki Nishimura, Kazuhisa Ori, Kenichi Ichinose

Patent number: 11206751Abstract: A magnetic field shielding structure includes a magnetic field generating source configured to generate a magnetic field. The magnetic field shielding structure further includes a shielding member that includes a pair of layers. The pair of layers includes a layer having high magnetic permeability, and a layer having low magnetic permeability laminated with the layer having high magnetic permeability. The layer having high magnetic permeability is closer to the magnetic field generating source than the layer having low magnetic permeability.Type: GrantFiled: November 24, 2020Date of Patent: December 21, 2021Assignee: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Masayuki Yoshikawa, Kenichi Ichinose, Kazuhisa Ori, Hiroyuki Nishimura, Hidetoshi Katoh
