Patent number: 10511066Abstract: A battery pack cooling system includes a plurality of cells disposed in an internal space of a battery pack case so as to form a cooling passage configured to cool the cell modules by cooling air flowing in the cooling passage. The cooling passage includes a cooling air inlet passage, a cooling air exhaust passage, and a plurality of cooling branch passages disposed to connect the cooling air inlet passage and the cooling air exhaust passage in parallel. A minimum temperature sensor is disposed in the upstream position to measure a lowest temperature region in a first cell module. A maximum temperature sensor is disposed in the downstream position which becomes a highest temperature region in the first cell module. Another temperature sensor is disposed in a second cell module to measure the temperature of either the highest temperature or the lowest temperature in the second cell module.Type: GrantFiled: February 7, 2019Date of Patent: December 17, 2019Assignee: Nissan Motor Co., Ltd.Inventors: Toyoki Iguchi, Hiroaki Hashimoto, Masayoshi Saeki, Hiroaki Saitou, Shigeyuki Kiyota, Yoshiyuki Tanaka, Hiroshi Iwata, Hiroshi Hoshi, Akira Kotaki, Nayuta Yamachi, Toshiyuki Yoshida, Chikara Kikkawa, Takeshi Haga

Patent number: 9902332Abstract: An electromagnetic wave shielding structure of a console installed in a passenger compartment of a vehicle has an electrical instrument installed in the console from which electromagnetic waves are radiated, a transmission including a metal member that receives the electromagnetic waves and transmits the electromagnetic waves to the passenger compartment and separated by a distance from the electrical instrument, and a shielding member located between the electrical instrument and the transmission to function as a shield against the electromagnetic waves radiated from the electrical instrument. The transmission is located in a shield region defined such that an electromagnetic wave radiating portion provided at the electrical instrument from which the electromagnetic waves are radiated is connected to a circumferential edge of the shielding member via a straight line, and the line is continuously moved along the circumferential edge of the shielding member around the electromagnetic wave radiating portion.Type: GrantFiled: August 12, 2014Date of Patent: February 27, 2018Assignee: NISSAN MOTOR CO., LTD.Inventors: Masayoshi Saeki, Kouta Terada, Hideaki Ootsuka, Akitomo Ootake
