Problems solved by technology

The known mobile charging points have the disadvantage that the internal energy store should be operated within a predetermined temperature range in order to keep the losses (Verschleiß), ie capacity loss (Kapazitätsverlust) of the internal energy store as small as possible
[0007] The charging stations known from the prior art all have the disadvantage that only cooling of the internal energy store of the charging station is provided

Embodiment Construction

[0038] exist figure 1 , a preferred embodiment of a mobile charging post 1 according to the invention is schematically depicted in front view. The mobile charging post 1 has a charging post housing 17 which is designed to be movable by means of wheels 15 of the mobile charging post 1 . The wheels 15 can, for example, be arranged in a retractable manner and be configured in the charging post housing 17 . Inside the charging post housing 17 are arranged the first internal energy store 2 , the second internal energy store 13 , the power electronics 4 and the fluid cooling circuit 5 . The fluid cooling circuit 5 and the components of the mobile charging point 1 which are technically connected to the fluid cooling circuit are in figure 2 is further clarified in. In order to electrically couple the mobile charging point 1 to the electric vehicle, the mobile charging point 1 has a charging point connection 3 with two charging sockets 18 . The mobile charging point can be operate...

Abstract

A mobile charging pile (1) for charging a battery pack of an electric vehicle is provided with a first internal energy storage device (2) for storing and outputting electric energy; a charging pile interface (3) which is used for electrically coupling the mobile charging pile (1) with an electric vehicle interface of the electric vehicle; a power electronic device (4) for controlling a charging current for charging a battery pack of the electric vehicle with electrical energy from the first internal energy store (2); a fluid cooling circuit (5) cooling the first internal energy store (2); anda heating device (6) having at least one heating element (7), which is designed separately from the power electronics, for heating the first internal energy store (2). The power electronic device (4)can be thermally coupled to the fluid cooling circuit (5) such that lost heat of the power electronic device (4) can be introduced into the fluid cooling circuit (5) to heat the first internal energystore (2). The invention also relates to a method for operating the mobile charging pile (1).

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 method for operating a mobile charging point according to the invention. 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 charging point plug with a charging cable. The charging process...
