A vehicle includes: an electronic device accommodated in an accommodation case of a power storage device; and a signal wiring connected to an electronic device and an in-vehicle device, the signal wiring being a signal wiring in which a signal to be received or transmitted by the electronic device or the in-vehicle device travels. An exhaust pipe is disposed at a position adjacent to a first side surface, and the signal wiring is drawn out from the second side surface to outside of the accommodation case.

Vehicle

Defective assembling of a duct to a battery module is reduced. A distribution duct has a plurality of distribution paths supplying refrigerant to each of a plurality of ventilation paths. A distribution path and a ventilation path are connected by an insertion structure in which the distribution path is inserted into the ventilation path. A distribution path has an open outlet end surrounded by a coupling portion, and is connected to a ventilation path via a planar sealing structure in which a sealing material is held on the coupling portion in a compressed state.

Power storage device cooling structure

An electrical connection box mounted on a vehicle and used for connecting a plurality of on-board loads to an on-board power supply, comprising: a box main body that is provided with an opening at a side and that accommodates an electrical component for the connecting; a cover body that covers the opening and that is provided with a protrusion portion protruding outward beyond the opening; an insertion hole that is provided a side wall of the box main body and that allows for insertion of an electric wire to be connected to the electrical component; and an extension portion that extends outward from a portion of the protrusion portion corresponding to the insertion hole and that bends arcuately.

Electrical connection box

An electrical connection box comprising a box main body that accommodates an electrical component and a connector for connection with an electrical wire that is provided in a protruding manner on an outer surface of the box main body, the electrical connection box being mounted on a vehicle and used for connection of a plurality of on-board loads to an on-board power supply comprises a protector that is provided in a protruding manner along a protrusion direction of the connector and protects the connector.

A battery pack includes a plurality of battery modules that includes a plurality of battery cells, a battery cell holder, a second-electrode assembly including a plurality of second-electrode bus bar plates, a first-electrode assembly, and a cover. The first-electrode assembly includes a plurality of first-electrode bus bar plates, a first-electrode terminal, a second-electrode terminal connected to one of the plurality of second-electrode bus bar plates, and an inter-electrode bus bar connecting the second-electrode bus bar plate and one of the first-electrode bus bar plate and the first-electrode terminal. The first-electrode assembly is in a first pattern or a second pattern. An arrangement of the first-electrode terminal and the second-electrode terminal in the battery module differs according to the pattern of the first-electrode assembly.

Battery pack

A battery pack structure includes a chamber, a cooling duct arranged outside the pack case, and a connector that communicates the chamber and the cooling duct with each other. The connector includes a first opening, which is connected with the chamber in a state of being sealed by a first sealing member, a second opening, which is connected with a cooling duct in a state of being sealed by a second sealing member, a first sealing surface, which is formed in a peripheral part of the first opening and is either a tube-shaped surface or a plane that faces a chamber inlet surface though the first sealing member, and a second sealing surface, which is formed in a peripheral part of the second opening and is a tube-shaped surface or a plane that faces a duct outlet surface through the second sealing member.

Battery pack structure including cooling duct outside pack case connected to chamber inside pack case by connector and first and second sealing members

Disclosed is a battery pack that is mountable in a vehicle. The battery pack includes a plurality of battery modules, and a battery case that accommodates the battery modules. The battery case includes a first frame, a second frame provided across the battery modules from the first frame, and a connection portion that connects the first frame and the second frame. The second frame is provided with a protrusion that protrudes in a direction from the first frame toward the second frame.

A protective frame structure includes: a lower frame; an intermediate frame that is interlinked with the lower frame and is situated above the lower frame; and an upper frame that is interlinked with the intermediate frame and is situated abobe the intermediate frame, wherein a mounting space in which a battery module is configured to be mounted is formed between the lower frame and the intermediate frame, an upper space is formed between the intermediate frame and the upper frame, and the intermediate frame is deformed upward when an external load has been applied to the protective frame structure.

Protective frame structure

An electricity storage device includes a first battery stack (), a second battery stack (to), and a case () that accommodates the first battery stack and the second battery stack. Each of the first battery stack and the second battery stack includes a plurality of cells () that are aligned and the second battery stack is placed under the first battery stack. The supporting member () that supports the first battery stack is placed between the first battery stack and the second battery stack and is fixed to the case.
