Structure for securing batteries used in an electric vehicle

A structure for securing each battery of a plurality of batteries for driving an electric vehicle in the electric vehicle in a condition in which said plurality of batteries have been compactly disposed and wherein each said battery has a bottom, sides and upper surface, comprising;

• a battery box having a box body,
• an inner spacer member in said box body for accommodating said plurality of batteries in said box body of said battery box, wherein said inner spacer member has an upper inner spacer member for pressing and holding said upper surface of each said battery of said plurality of batteries, said upper inner spacer member having concave portions for defining predetermined spaces between said upper surface of each said battery of said plurality of batteries and said upper inner spacer member, and
• said inner spacer member further including partition members formed as an integral body, said partition members defining a plurality of spaced compartments for fixedly disposing each said battery of said plurality of batteries in a compartment of said plurality of spaced compartments in a condition in which each said battery is spaced and separated on all said sides of that said battery from all other said batteries of said plurality of batteries, each said compartment of said plurality of spaced compartments receiving only one said battery of said plurality of batteries in said compartment.

• a battery box having a box body,
• an inner spacer member in said box body for accommodating said plurality of batteries in said box body of said battery box,
• said inner spacer member including partition members formed as an integral body, said partition members defining a plurality of spaced compartments for fixedly disposing each said battery of said plurality of batteries in a compartment of said plurality of spaced compartments in a condition in which each said battery is spaced and separated on all said sides of that said battery from all other said batteries of said plurality of batteries, each said compartment of said plurality of spaced compartments receiving only one said battery of said plurality of batteries in said compartment, and
• an intake air passage member for introducing cooling air into said box body, said intake air passage member comprising a chamber in which the cooling air is received, at least one first passage for introducing external cooling air into a lower side of said chamber from an upper portion of said chamber, and a second passage provided on an upper side in said chamber and used to introduce the cooling air brought into said chamber into said body.

A structure for securing each battery of a plurality of batteries for driving an electric vehicle in the electric vehicle in a condition in which said plurality of batteries have been compactly disposed and wherein each said battery has a bottom, side walls and top, comprising;

• a battery box having a box body,
• an inner spacer member in said box body for accommodating said plurality of batteries in said box body of said battery box,
• said inner spacer .member further including partition members formed as an integral body, said partition members defining a plurality of spaced compartments for fixedly disposing each said battery of said plurality of batteries in a compartment of said plurality of spaced compartments in a condition in which each said battery is spaced and separated on all said sides of that said battery from all other said batteries of said plurality of batteries, each said compartment of said plurality of spaced compartments receiving only one said battery of said plurality of batteries in said compartment, and
• wherein said partition members of said inner spacer member include wall means extending between at least portions of adjacent said side walls of all of said plurality of batteries, said wall means including upwardly extending wall means extending vertically upward from said bottom of each said battery of said plurality of batteries and downwardly extending wall means extending vertically downward from said top of each said battery of said plurality of batteries thereby providing a cooling air space between said plurality of batteries in a vertical space between said upwardly extending wall means and said downwardly extending wall means.
