Abstract
Description
Technical field:
[0001] The invention relates to mobile energy supply, in particular a technical system for the automated, branch-wide lending and return of power banks by means of a digital infrastructure with a user app. State of the art:
[0002] Existing systems usually only allow location-based return options and have shortcomings in terms of automation, real-time monitoring and integration into existing digital customer platforms. Technical problem:
[0003] The task is to provide an automated, location-independent system for the flexible lending and return of mobile chargers, which can be seamlessly integrated into existing digital customer apps and efficiently managed. Solution to the problem:
[0004] The invention comprises at least one stationary rental station equipped with integrated, rechargeable power banks, a mobile user app for authentication and control of the rental and return process, and a cloud-based central management unit that automatically monitors and updates the condition, location, and availability status of the power banks in real time. Returns are automated to any participating rental station, regardless of the original rental location. Usage is billed immediately and automatically via the central data processing unit. Advantages of the invention: • Automatic, cross-branch return detection • Real-time monitoring and management of devices • Full integration into existing digital customer platforms • User-friendly, transparent tariffs • High scalability through easy integration of new partner locations Example implementation:
[0005] A user authenticates themselves via QR code using the mobile app at a rental station in a supermarket. They automatically receive a fully charged power bank. After use, the user returns the power bank to another partner store. The return is automatically detected, the usage time recorded, and the usage is immediately and automatically billed and confirmed via the app.
Claims
[1] (Main claim): System for location-independent, automated lending and return of mobile chargers (power banks), comprising: • at least one stationary rental station comprising several power banks, each power bank having an integrated charging unit, • a mobile application (app) which is set up to identify and authenticate the user using a QR code or similar digital authentication methods, • a cloud-based, central data processing unit for automatic monitoring and management of the rental status, charge level and location data of each individual power bank, whereby • the rental station is connected to the central data processing unit and the user app via a digital communication interface, • the lending process is only triggered after successful user authentication via the app, • the return of the power bank to any participating rental station is automatically detected, regardless of the original rental location, • the usage period directly and automatically from the central The data processing unit is recorded and billed. [2] (Subclaim to claim 1): System according to claim 1, characterized by , that a usage-based tariff is billed automatically and on a time-based basis via the central data processing unit. [3] (Sub-claim to claim 1 or 2): System according to claim 1 or 2, characterized by that a digital deposit system for securing the borrowed devices is integrated via the user app
