Structure for mounting batteries onto electric vehicles
View Patent ↗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.
1. A structure for mounting a battery onto an electric vehicle including a pair of first body members extending in a longitudinal direction of the electric vehicle and a battery case, which contains a battery, disposed between said pair of first body members, said structure comprising:
a high-voltage cable, which is disposed between at least one of the first body members and a side surface of said battery case, connecting said battery and an external device disposed outside of said battery case, a dent portion being formed on a side surface of said battery case facing the first body member; and
a first supporting member extending in a transversal direction connecting between the pair of first body members to support the bottom surface of the battery case,
said dent portion including a concave side wall, which faces the first body member, having a cable hole portion through which said high-voltage cable is installed,
said high-voltage cable being supported by said first supporting member to extend in parallel to said first body member,
said concave side wall being kept at a distance, which becomes greater while the outer diameter of the high-voltage cable becomes greater, from said first body member.
2. The structure for mounting the battery onto the electric vehicle according to claim 1 wherein
said high-voltage cable has a hole connector being connected to the battery in the battery case.
3. The structure for mounting the battery onto the electric vehicle according to claim 1 wherein
an expansion coefficient of the battery case and an expansion coefficient of a cover plate are substantially the same.
