Publication number: 20240128517Abstract: Disclosed is an electrode assembly, a battery, and a battery pack and a vehicle including the same. In the electrode assembly, a first electrode, a second electrode, and a separator interposed therebetween are wound based on an axis to define a core and an outer circumference. The first electrode includes an uncoated portion at a long side end thereof and exposed out of the separator along a winding axis direction of the electrode assembly. A part of the uncoated portion is bent in a radial direction of the electrode assembly to form a bending surface region that includes overlapping layers of the uncoated portion, and in a partial region of the bending surface region, the number of stacked layers of the uncoated portion is 10 or more in the winding axis direction of the electrode assembly.Type: ApplicationFiled: January 19, 2022Publication date: April 18, 2024Applicant: LG ENERGY SOLUTION, LTD.Inventors: Hae-Jin LIM, Jin-Hak KONG, Soon-O LEE, Kyu-Hyun CHOI, Do-Gyun KIM, Su-Ji CHOI, Kwang-Su HWANGBO, Geon-Woo MIN, Min-Ki JO, Jae-Won LIM, Hak-Kyun KIM, Je-Jun LEE, Ji-Min JUNG, Jae-Woong KIM, Jong-Sik PARK, Yu-Sung CHOE, Byoung-Gu LEE, Duk-Hyun RYU, Kwan-Hee LEE, Jae-Eun LEE, Bo-Hyun KANG, Pil-Kyu PARK

Patent number: 8354910Abstract: A coil block and an electronic device using the same are provided. The coil block includes a first coil, a second coil, a core having an intermediate layer for separating the first coil and the second coil from each other, and a shield for shielding the first coil, the second coil, and the intermediate layer, wherein the first coil and the second coil have the same winding direction. According to the coil block and the electronic device, the filtering can be performed without any inductance offset even if the PWM signal having the inversed phase or the same phase is inputted. Also, since two windings can be wound on to one core using a common coil, the cost and the size of the coil block can be reduced.Type: GrantFiled: March 20, 2007Date of Patent: January 15, 2013Assignee: Samsung Electronics Co., Ltd.Inventors: Kyu-eun Park, Dae-kyoung Noh, Sung-woo Kim

Patent number: 8345886Abstract: A method and apparatus for detecting a malfunctioning speaker are provided. The apparatus detects a speaker abnormality by identifying the state of the speaker when turning the power on or off, switching from standby mode to play mode, or performing testing. The apparatus generates an audio signal having a frequency higher than a particular frequency, outputs the audio signal to the speaker, and determines that the speaker is malfunctioning if the level of a fed-back frequency signal is lower than a reference level. If the speaker is determined to be malfunctioning, the power supply is cut and the danger of a fire starting is accordingly reduced.Type: GrantFiled: January 17, 2008Date of Patent: January 1, 2013Assignee: Samsung Electronics Co., Ltd.Inventor: Kyu-eun Park
