Problems solved by technology

[0006]The known mobile charging points have the disadvantage that they can only be moved with difficulty, especially due to their large dead weight, usually up to 3 tons, and are often expensive only in use can only be moved under the condition of auxiliary tools
Furthermore, the charging of the internal energy storage is disadvantageous due to the inaccessible charging station interface
Finally, such mobile charging points are relatively expensive to produce, especially because of the two power electronics required

Embodiment Construction

[0036] exist figure 1 , a preferred embodiment of a mobile charging point 1 according to the invention is schematically depicted in a side view in a transport situation. The mobile charging point 1 has a charging point housing 9 with a plurality of rollers 10 . In this exemplary embodiment, the mobile charging point 1 has an optional electric motor 11 arranged in the charging point housing 9 for driving the wheels 10 . Preferably, the electric motor 11 or another device is configured for raising or lowering the wheel 10 . exist figure 1 In the transport situation shown, the wheels 10 are extended so that the mobile charging point 1 can be moved (verfahr bar). An internal current store 2 is arranged in the charging post housing 9 for storing and for outputting electrical energy. The mobile charging point 1 has a charging point connection 3 with a plurality of charging plugs 8 , which are electrically coupled to the internal energy store 2 via invisible charging cables. Alt...

Abstract

The invention relates to a mobile charging pile (1) for charging a battery pack of an electric vehicle, and the mobile charging pile (1) comprises an internal energy store (2) for storing and outputting electrical energy; a charging pile interface (3) which is used for electrically coupling the mobile charging pile (1) with an electric vehicle interface of an electric vehicle; and a power electronic device (4) for controlling a charging current for charging a battery pack of the electric vehicle with electrical energy from the internal energy store (2). The charging pile interface (3) is designed to be electrically coupled to an external current source, and the power electronic device (4) are designed to control a charging current for charging the internal energy store (2) with electricalenergy from the external current source (5). The invention further relates to a mobile charging pile system (20) and to a method for operating a mobile charging pile system (20).

Description

technical field [0001] The invention relates to a mobile charging pile for charging a battery pack of an electric vehicle. Furthermore, the invention relates to a mobile charging point system with a charging station and a mobile charging point and to a method for operating the charging point system. Background technique [0002] Different charging infrastructures are known for charging the battery packs of electric vehicles. Basically, a distinction is made here between two charging point infrastructures, namely charging point infrastructures with fixed charging points and charging point infrastructures with mobile charging points. [0003] Stationary charging piles are fixedly installed at one location and connected to the grid. The fixed charging pile has a charging pile interface for electrically coupling the charging pile with the electric vehicle interface of the electric vehicle. The charging point connection is designed, for example, as a charging point socket or a...
