Patent number: 11912217Abstract: A vehicle is positively charged with static electricity due to an external factor. The vehicle includes a battery, a static eliminator sheet, and a holding member. The battery includes at least one cell, an electrolyte, a resin case, and negative and positive terminals. The resin case accommodates the components and electrolyte of each cell. The negative terminal is grounded to the vehicle body. The positive terminal is supplied with electric power from a charger. The static eliminator sheet is made of a material on a positive side of a triboelectric series with respect to a material of the resin case. The holding member holds the static eliminator sheet and the resin case in contact with each other. The holding member holds the battery at a predetermined location of the vehicle body in a state where the resin case and the static eliminator sheet are slidable due to vehicle body vibrations.Type: GrantFiled: February 24, 2023Date of Patent: February 27, 2024Assignee: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Koushi Yamada, Junichi Sudo, Kenichiro Sakurai, Kazuhiro Maeda, Toshio Tanahashi

Publication number: 20230304632Abstract: In a vehicle having a microscopic dynamics friction mechanism formed of at least two parts and charged to a positive potential due to traveling, a lubricant in which first additive fine particles made of a resin that generates a negative potential are uniformly mixed with an electrically insulating base oil is disposed in a clearance between members of the friction mechanism. While the first additive fine particles are in frictional contact with the member, neutralization and elimination of the positive potential of the member are started. The first additive fine particles are attracted by a Coulomb force to the positive potential of the surface of the member other than a frictional contact part of the member when floating in the electrically insulating base oil and moving and circulating. The neutralization and elimination of the positive potential of the member are continued.Type: ApplicationFiled: March 30, 2021Publication date: September 28, 2023Inventors: Junichi SUDO, Youji KANEHARA, Koushi YAMADA, Kenichiro SAKURAI, Toshio TANAHASHI, Ko TANIMURA, Tomonobu KOMORIYA
