Abstract
To minimize temperature differences between batteries and also between battery cells for effectively cooling the batteries uniformly, a fan structure is disposed on one side of a box assembly of a battery box and four of six surfaces of each of the batteries which are box-shaped are covered with thermally insulating members. When a motor of the fan structure is energized, the fan structure introduces cooling air forcibly into the box assembly to cool the two exposed surfaces of each of the batteries. The battery box with the fan structure is relatively simple in structure, lightweight, economical, and can easily be inspected and serviced for maintenance.
Claims35
A temperature control structure for controlling the temperatures of batteries, comprising:
- a casing;
- a plurality of batteries housed in said casing, each of said batteries being of a box shape having six surfaces;
- thermally insulating members covering four of said six surfaces of each of said batteries and leaving two uninsulated surfaces;
- air passages defined in said casings, the two uninsulated surfaces of each of said batteries being exposed to said air passages;
- and
- means for forcibly applying cooling air through said air passages to the two uninsulated surfaces of each of said batteries.
A battery box comprising:
- a casing;
- at least one box-shaped battery housed in said casing;
- air passages defined in said casing along side surfaces of said battery;
- and
- thermally insulating members disposed in said casing out of said air passages in covering relation to surfaces of said battery other than said side surfaces.
A temperature control structure for controlling the temperatures of batteries for propelling an electric vehicle, comprising:
- a casing having a bottom plate;
- a plurality of batteries housed in said casing, each of said batteries being of box shape having six surfaces;
- at least one air duct mounted on a lower surface of said bottom plate of the casing for applying cooling air to two parallel side surfaces of said six surfaces of each of said batteries and
- a support mounted on said casing and supporting at least the bottom plate of the casing, said support having a hollow structure serving as a duct for applying cooling air to the side surfaces of said batteries.
A temperature control structure for controlling the temperatures of a plurality of batteries in an electric vehicle, each of which batteries is box-shaped and has two parallel side surfaces perpendicular to the cells in the battery, comprising:
- a casing having a bottom plate for receiving the plurality of batteries;
- and
- at least one air duct mounted on a lower surface of said bottom plate of the casing for applying cooling air only to the two parallel side surfaces of each of said batteries.
