1. A battery-changing vehicle comprising:
- a mobile carriage defining a loading deck for receiving and transporting a battery, the mobile carriage being longitudinally movable along a first axis;
a transfer assembly connected to the mobile carriage, the transfer assembly comprising a transfer arm capable of horizontally transferring a battery to and from the loading deck without supporting the full weight of a battery and configured to rotate about a vertical axis;
a frame disposed above and connected to the mobile carriage; and
a boom assembly connected to the frame, the boom assembly comprising a lift hoist capable of lifting a battery from the loading deck, the lift hoist being at least laterally movable relative to the loading deck along a second axis that is perpendicular to the first axis, the lift hoist being laterally movable between an extended disposition, at which the lift hoist is cantilevered away from the loading deck, and a withdrawn disposition, at which the lift hoist is disposed above the loading deck.

Abstract
A battery-changing vehicle includes a mobile carriage, a frame disposed above the mobile carriage, and a boom assembly connected to the frame. The mobile carriage defines a loading deck for receiving and transporting a battery. The boom assembly includes a lift hoist that lifts a battery to and from the loading deck. The lift hoist is capable of lateral movement between an extended disposition, at which the lift hoist is cantilevered away from the loading deck, and a withdrawn disposition, at which the lift hoist is disposed above the loading deck. The battery-changing vehicle may also include a transfer arm capable of transferring a battery to and from the loading deck.
