Disclosed are systems for exchanging batteries of an unmanned aerial vehicle (UAV). In some embodiments, a system may include a battery holding tube that is located on the UAV and that includes a first end with a first opening and a second end with a second opening and a battery loader configured to cause a battery to move into the battery holding tube through the first opening in a direction parallel to the center axis of the battery holding tube, wherein the center axis of the battery is parallel to the center axis of the battery holding tube, and cause the battery to move out of the battery holding tube through the second opening in a direction parallel to the center axis of the battery holding tube, wherein the center axis of the battery is parallel to the center axis of the battery holding tube.

An object is to provide a technology capable of easily mounting a battery into a battery-driven machine. A solution is a battery-equipped carriage (12) which is loaded into or unloaded from a storage (20) in a battery-driven machine (14). The battery-equipped carriage (12) includes: a chassis (24); and a front wheel caster (26) and a rear wheel caster (28) which respectively support a front part and a rear part of the chassis (24) with respect to a ground (G). Here, the front part of the chassis (24) is positioned to be higher than the rear part of the chassis (24) with respect to the ground (G) such that the chassis (24) is inclined.

Battery exchange system for an electric vehicle, comprising: a battery unit; a battery receiving unit adapted for being fixed at or near a bottom surface of an electric vehicle and comprising a housing with an opening at a bottom side of housing for at least partially receiving the battery unit in the housing through the opening, wherein the battery receiving unit has a central axis which extends through the opening; wherein the battery receiving unit is adapted for allowing movement of the battery unit along its central axis between an unmounted position below the battery receiving unit and a mounted position at least partially within the battery receiving unit, wherein the battery unit comprises first engagement elements and the battery receiving unit comprises second engagement elements, each of the first and second engagement elements being adapted for engaging each other while moving relative to each other along an associated sloping path in order to lift the battery unit from the unmounted position to the mounted position or lower the battery unit from the mounted position to the unmounted position, wherein said associated sloping path slopes with respect to a plane normal to the central axis.
