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
