A battery unit comprises a battery case, and a plurality of battery modules stored and held in the battery case. The battery case includes a bottom wall and a partition. The plurality of battery modules are mounted on the bottom wall. The partition is provided and erected on the bottom wall. The partition separates the battery modules adjacent in a second direction traversing a first direction. The first direction is oriented from a first end of the battery case at which an inlet is formed to a second end at which an outlet is formed. The partition extends along a plane where the battery modules face each other in the second direction along the battery modules. The partition is inclined in the extending direction.

Battery unit

A battery unit is provided under a floor panel. The battery unit is arranged between a pair of right and left side members. The battery unit is provided with a battery case. The battery case includes a tray member and cover member. Electric components are contained in the battery case. Beam members made of metal are attached to the tray member. Both end portions of these beam members are supported by the side members. The tray member includes a resin and insert members made of metal provided inside the resin. The insert members include metal plates arranged on the front side and rear side of the electric components.

Electric vehicle

A battery case for containing therein battery modules includes a tray member, cover member, and seal member. The seal member is applied to a joint part between the tray member and cover member. Insert members made of metal are embedded in the resin of the tray member. Each of the insert members is provided with an embedded bolt a threaded part of which protrudes upward, and embedded nuts. The battery case is provided with first fastening sections and second fastening sections. In the first fastening section, a nut member is screwed onto the embedded bolt from above the cover member. In the second fastening section, a bolt member is screwed into the embedded nut from above the cover members.

Battery case for electric vehicle

A structure for mounting a battery onto an electric vehicle comprising: a body member, which is made from metal, forming a body of the electric vehicle a battery case, which is made from resin, containing the battery charging electric power for driving the electric vehicle; a framework member, which is made from metal, being embedded in the battery case; and a connecting member connecting between the framework member and the body member.

Structure for mounting batteries onto electric vehicles

A structure for mounting a battery onto an electric vehicle comprises: a high-voltage cable, which is disposed between at least one of first body members of the vehicle and a battery case containing a battery, connecting the battery and an external device disposed outside of the battery case; and a dent portion being formed on a side surface of the battery case faces to the first body member. The dent portion includes a concave side wall, which faces the first body member, having a cable hole portion through which the high-voltage cable is installed. The concave side wall is kept at a distance from the first body member defined based on a diameter of the high-voltage cable.
