Patent number: 10629887Abstract: When a temperature inside a secondary battery becomes high and a gas pressure inside a battery case increases, an inversion plate is pressed due to the gas pressure so as to project and curve in a projecting manner toward an external terminal board. Due to such a deformation, a load is transmitted to a current interruption piece via a load transmission portion. At this time, due to a pushing-up force of the load transmission portion, a vulnerable breaking portion forming part of a peripheral edge of the current interruption piece breaks, so that the current interruption piece is displaced to bend in a V-shape via a folding portion. As a result, the secondary battery is brought into an unusable state. Such a configuration can attain simplification of a structure to interrupt a current.Type: GrantFiled: May 9, 2016Date of Patent: April 21, 2020Assignee: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Yuta Nemoto, Toshinori Okura, Takeshi Iida, Noriyuki Maruyama, Hiroaki Yoshida

Patent number: 10566927Abstract: An optimization engine determines an optimal configuration for a solar power system projected onto a target surface. The optimization engine identifies an alignment axis that passes through a vertex of a boundary associated with the target surface and then constructs horizontal or vertical spans that represent contiguous areas where solar modules may be placed. The optimization engine populates each span with solar modules and aligns the solar modules within adjacent spans to one another. The optimization engine then generates a performance estimate for a collection of populated spans. By generating different spans with different solar module types and orientations, the optimization engine is configured to identify an optimal solar power system configuration.Type: GrantFiled: November 14, 2012Date of Patent: February 18, 2020Assignee: Sunrun, Inc.Inventors: Billy Hinners, Gary Wayne
