Publication number: 20230347746Abstract: A power distribution device comprises a system main relay, i.e., SMR, a pre-charge circuit and a control board. The SMR selects between on and off of a current between a power conversion device and a battery. The pre-charge circuit includes a charge resistor and a charge switch which are provided to charge the smoothing capacitor with power supplied from the battery. The control board enables a current smaller than a current flowing through the SMR. The SMR and the control board are arranged in the x-direction via the pre-charge circuit.Type: ApplicationFiled: July 11, 2023Publication date: November 2, 2023Applicant: DENSO CORPORATIONInventors: Koichi UMEDA, Tatsuki NISHIMATA, Takashi KAWASHIMA

Patent number: 11223091Abstract: An electric power storage device includes at least one electric power storage cell having a first end provided with a first electrode, and a second end provided with a second electrode; a first electrode bus bar that is disposed on a side of the first end and is connected to the first electrode; and a second electrode bus bar that is disposed on a side of the second end and is connected to the second electrode. The first electrode bus bar is provided with a connection line connected to the first electrode. The first electrode bus bar and the second electrode bus bar are joined to each other by ultrasonic joining. A joint portion between the first electrode bus bar and the second electrode bus bar is disposed at a position that is closer to the second end than to the first end.Type: GrantFiled: February 6, 2019Date of Patent: January 11, 2022Assignee: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Kenta Watanabe, Nobuyoshi Fujiwara, Koichi Umeda

Patent number: 10411312Abstract: A first fin is formed on a first inside wall surface to protrude therefrom. The first fin exchanges heat between fluid and the first inside wall surface. A first fluid passage is divided between a first region that is a space where the first fin is arranged, and a second region that is a space where the first fin is not arranged. Fluid flows from the second region into the first region. The first fin includes an inflow port through which fluid flows into the first region, and an outflow port through which fluid flows out of the first region. The first fin is formed to extend from the inflow port to the outflow port. An area of the inflow port is larger than a cross-sectional area of the first fluid passage when viewed in a flow direction of fluid.Type: GrantFiled: December 22, 2015Date of Patent: September 10, 2019Assignee: DENSO CORPORATIONInventors: Yoshimitsu Inoue, Koichi Umeda, Koji Yamashita, Hiroyoshi Yamamoto, Shota Iguchi
