A current collector for a non-track-bound, electrically driven vehicle for feeding electrical energy from a two-pole overhead line system with two contact wires. Two upper arms are rotatably connected to an adjustable lower arm by toggle joints. Each upper arm carries a contact rocker for contacting the contact wires. Coupling bars are rotatably connected to the upper arms and articulated so that adjustment of the lower arm forces adjustment of the upper arms. A compensating rocker compensates for a height difference between the contact rockers with a rocker stand and a rocker beam. The rocker stand can be rotatably connected to the vehicle and the rocker beam is connected to the coupling bars by way of compensating joints on either side of the rocker joint. At least one stop element limits a rotational movement of the rocker beam about a rocker joint axis of the rocker joint.

A vehicle is provided that determines a first triggering event in predetermined triggering event information has occurred, in response to a first event, automatically forwards a first communication to a selected third party vendor to preorder a product or service of the selected third party vendor in connection with a transaction with the user, determines a second triggering event in the triggering event information has occurred, and in response to the later second event, automatically sends an authorization to complete the transaction by providing financial information to the selected third party vendor.

An electrically driveable vehicle, in particular a rail vehicle, includes an intermediate DC circuit, an in-vehicle, three-phase on-board electrical system fed by the intermediate DC circuit, at least one drive motor fed by a converter, and at least one coolant pump for pumping a coolant that cools the converter. In addition to the in-vehicle three-phase on-board electrical system, the vehicle also has a second on-board electrical system. The at least one coolant pump is connected to the second on-board electrical system.
