Claims20
A material handling vehicle, comprising:
- a battery compartment;
- and
- a battery disposed in the battery compartment and contained within an enclosure, the enclosure comprising:
- a first piece of bent sheet metal;
- a second piece of bent sheet metal bolted to the first piece of bent sheet metal;
- a metal base plate positioned below a bottom surface of the first piece of bent sheet metal and below a bottom surface of the second piece of bent sheet metal, the first piece of bent sheet metal and the second piece of bent sheet metal being bolted to the metal base plate;
- and
- a lid assembly comprising a gasket, the lid assembly positioned above a top surface of the first piece of bent sheet metal and above a top surface of the second piece of bent sheet metal such that the lid assembly seals the enclosure together with the first piece of bent sheet metal, the second piece of bent sheet metal, and the metal base plate;
- wherein the first piece of bent sheet metal, the second piece of bent sheet metal, the metal base plate, and the lid assembly are not welded.
A method for manufacturing an industrial battery for a material handling vehicle, the method comprising:
- forming a lower metal tray on a top surface of a metal base plate;
- disposing a battery cell on the lower metal tray;
- bolting the battery cell to the metal base plate;
- bolting a first piece of bent sheet metal to a second piece of bent sheet metal;
- bolting the first piece of bent sheet metal and the second piece of bent sheet metal to the metal base plate;
- and
- bolting a lid assembly comprising a gasket to the first piece of bent sheet metal and the second piece of bent sheet metal such that the first piece of bent sheet metal, the second piece of bent sheet metal, the metal base plate, and the lid assembly together form a sealed enclosure for the battery cell;
- wherein the method does not include welding of the first piece of bent sheet metal, the second piece of bent sheet metal, the metal base plate, or the lid assembly.
A battery for a material handling vehicle, comprising:
- a plurality of battery cells;
- and
- an enclosure comprising:
- a first piece of bent sheet metal;
- a second piece of bent sheet metal bolted to the first piece of bent sheet metal;
- a metal base plate positioned below a bottom surface of the first piece of bent sheet metal and below a bottom surface of the second piece of bent sheet metal, the first piece of bent sheet metal and the second piece of bent sheet metal being bolted to the metal base plate;
- and
- a lid assembly comprising a gasket, the lid assembly positioned above a top surface of the first piece of bent sheet metal and above a top surface of the second piece of bent sheet metal such that the lid assembly seals the plurality of battery cells within the enclosure together with the first piece of bent sheet metal, the second piece of bent sheet metal, and the metal base plate;
- wherein the first piece of bent sheet metal, the second piece of bent sheet metal, the metal base plate, and the lid assembly are not welded.
