Abstract

A sealed lead-acid battery assembly for motive power vehicles is provided for. The battery tray assembly comprises a battery tray having a tray base adapted to support one or more sealed lead-acid batteries. The battery tray has three upstanding tray walls, consisting of two side walls and a front wall, which are connected to the tray base, a tray top connected to the upstanding tray walls, and one or more divider walls. The tray base, side walls, front wall, tray top, and divider wall define one or more compartments adapted to receive batteries and a compartment adapted to receive a battery charger. The battery tray has a generally open back which provides access for loading batteries into the battery compartments and for loading a charger into the charger compartment. Otherwise, the battery and charger compartments are substantially enclosed by the battery tray. The battery tray assembly further comprises a battery charger mounted in the charger compartment, and two or more sealed lead-acid batteries supported in the battery compartments. The batteries are electrically connected together to provide positive and negative termination.

Claims

1. A sealed lead-acid battery tray assembly for motive powered vehicles which comprises:

a battery tray including a tray base to support one or more sealed lead-acid batteries, three upstanding tray walls connected to the tray base, the upstanding tray walls consisting of two side walls and a front wall, a tray top connected to the upstanding tray walls, and one or more divider walls, the tray base, side walls, front wall, tray top, and divider walls defining one or more compartments to receive batteries and a compartment to receive a battery charger, the battery tray having a generally open back providing access for loading batteries into the battery compartments and loading a charger into the charger compartment, the battery and charger compartments being otherwise substantially enclosed by the battery tray;

a battery charger mounted in the charger compartment; and

two or more sealed lead-acid batteries supported in the battery compartments and electrically connected together to provide positive and negative termination.

2. The sealed lead-acid battery tray assembly of claim 1, wherein the divider walls include a vertical divider wall and wherein the charger compartment is defined by the vertical divider wall, front wall, tray base, tray top, and one of the side walls.

3. The sealed lead-acid battery tray assembly of claim 2, wherein the divider walls include a horizontal shelf to support one or more batteries and wherein the battery tray has two battery compartments defined by the horizontal shelf, front wall, tray base, tray top, vertical divider wall, and the other side wall.

4. The sealed lead-acid battery tray assembly of claim 1, wherein the depth of the tray top is greater than the depth of the tray base.

5. The sealed lead-acid battery tray assembly of claim 3, wherein the depth of the tray top is greater than the depth of the horizontal shelf.

6. The battery tray assembly of claim 1, wherein one of the tray walls defining the charger compartment has an access opening to allow access to controls of the charger mounted therein.

7. The battery tray assembly of claim 1, wherein a portion of the charger compartment is available for storing a power cord of the charger mounted therein and one of the tray walls defining the charger area has an opening adjacent to the power cord storage portion adapted to allow withdrawal and replacement of the power cord therein.

8. The battery tray assembly of claim 1, wherein the tray base has a lip projecting upwardly from the back edge thereof, the depth of the tray base being substantially equal to the width of a battery supported thereon.

9. The battery tray assembly of claim 3, wherein the horizontal shelf has a lip projecting upwardly from the back edge thereof, the depth of the horizontal shelf being substantially equal to the width of a battery supported thereon.

10. The battery tray assembly of claim 1, wherein the width of the battery compartments is substantially equal to the combined length of the batteries supported therein.

11. The battery tray assembly of claim 3, wherein the width of the battery compartments is substantially equal to the combined length of two batteries.

12. The battery tray assembly of claim 1, wherein the battery tray assembly comprises one or more brackets mounted within the battery compartments to restrict upward movement of batteries supported in the battery compartments.

13. The battery tray assembly of claim 3, wherein the battery tray assembly comprises one or more brackets mounted within the battery compartment on the vertical divider wall and the side wall defining the battery compartments, the brackets restricting upward movement of batteries supported in the battery compartments.

14. The battery tray assembly of claim 3, wherein the battery tray assembly includes one or more brackets mounted within the battery compartments on the vertical divider wall and the side wall defining the battery compartments, the brackets restricting upward movement of the batteries supported in the battery compartments and at least one of the brackets spacing one of the batteries from the vertical divider wall or side wall, wherein the width of the battery compartment is substantially equal to the combined length of two batteries and the space from the vertical divider wall or side wall.

15. The battery tray assembly of claim 1, wherein the tray base, front wall, and tray top are fabricated from a single sheet of metal.

16. A motive-powered vehicle which comprises a battery receptacle area, the battery tray assembly of claim 1 mounted on the battery receptacle area, and connectors for accepting the positive and negative termination from the battery tray assembly.

17. A motive-powered vehicle which comprises the battery tray assembly of claim 2 and connectors for accepting the positive and negative termination from the battery tray assembly.

18. A motive-powered vehicle which comprises the battery tray assembly of claim 3 and connectors for accepting the positive and negative termination from the battery tray assembly.

19. A motive-powered vehicle which comprises the battery tray assembly of claim 4 and connectors for accepting the positive and negative termination from the battery tray assembly.

20. A motive-powered vehicle which comprises the battery tray assembly of claim 5 and connectors for accepting the positive and negative termination from the battery tray assembly.
