Abstract

A trailer includes a first power equipment having an equipment battery pack, a charging device having a primary battery pack, and a docking station electrically connected to the primary battery pack. When the first power equipment is positioned in the docking station, the docking station supplies power from the primary battery pack to the equipment battery pack to recharge the equipment battery pack.

Claims (41)

1 . A trailer comprising:

a floor;

a wall;

a first power equipment including a plurality of wheels and a first equipment battery pack;

a second power equipment including a second equipment battery pack;

a charging device including a primary battery pack, wherein the charging device and the primary battery pack are separate from the first power equipment, and wherein the primary battery pack is supported on the floor or coupled to the wall;

a charging station configured to store and charge the second equipment battery pack; and

a docking station electrically connected to the primary battery pack, wherein when the first power equipment is positioned in the docking station, the docking station supplies power from the primary battery pack to the first equipment battery pack to recharge the first equipment battery pack.

2 . The trailer of claim 1 , wherein the docking station is arranged on a floor.

3 . The trailer of claim 2 , wherein the docking station includes a pair of recesses in the floor.

4 . The trailer of claim 3 , wherein the pair of recesses are each configured to receive a wheel of the first power equipment.

5 . The trailer of claim 1 , wherein the docking station includes a sensor configured to detect a presence of the first power equipment within the docking station.

6 . The trailer of claim 1 , further comprising a power outlet arranged on a sidewall, wherein the power outlet is externally accessible.

7 . The trailer of claim 6 , wherein the power outlet is configured to receive a utility connection and supply power from the utility connection to the primary battery pack.

8 . The trailer of claim 1 , further comprising a controller in communication with the first power equipment, wherein the controller is configured to determine a duration of time for the first equipment battery pack to recharge.

9 . The trailer of claim 1 , wherein the docking station wirelessly supplies power to the first equipment battery pack.

10 . A trailer comprising:

a floor;

a plurality of walls;

a first power equipment including a plurality of wheels and a first equipment battery pack;

a second power equipment including a second equipment battery pack;

a charging device including a primary battery pack, wherein the charging device and the primary battery pack are separate from the first power equipment, and wherein the primary battery pack is enclosed within an interior volumed defined by the floor and the plurality of walls;

a charging station configured to store and charge the second equipment battery pack; and

a docking station arranged on the floor, wherein the docking station is electrically connected to the primary battery pack and configured to wirelessly supply power to the first equipment battery pack via inductive charging.

11 . The trailer of claim 10 , wherein the docking station is configured to initiate inductive charging of the first equipment battery pack in response to the first power equipment being secured over the docking station.

12 . The trailer of claim 10 , wherein the docking station includes a pair of recesses in the floor.

13 . The trailer of claim 12 , wherein the pair of recesses are each configured to receive a wheel of the first power equipment.

14 . The trailer of claim 10 , wherein the docking station includes a sensor configured to detect a presence of the first power equipment within the docking station.

15 . The trailer of claim 10 , further comprising a power outlet arranged on a sidewall, wherein the power outlet is externally accessible.

16 . The trailer of claim 15 , wherein the power outlet is configured to receive a utility connection and supply power from the utility connection to the primary battery pack.

17 . The trailer of claim 10 , further comprising a controller in communication with the first power equipment, wherein the controller is configured to determine a duration of time for the first equipment battery pack to recharge.

18 . A trailer comprising:

a floor;

a wall;

a first power equipment including a plurality of wheels and a first equipment battery pack;

a second power equipment including a second equipment battery pack;

a charging device including a primary battery pack, wherein the charging device and the primary battery pack are separate from the first power equipment, and wherein the primary battery pack is supported on the floor or coupled to the wall;

a charging station configured to store and charge the second equipment battery pack; and

a docking station arranged on the floor, wherein the docking station is electrically connected to the primary battery pack and configured to wirelessly supply power to the first equipment battery pack via inductive charging.

19 . The trailer of claim 18 , wherein the docking station includes a pair of recesses in the floor.

20 . The trailer of claim 19 , wherein the pair of recesses are each configured to receive a wheel of the first power equipment.
