Definitions

  • the present invention relates to a charging station for mobile electrical consumers such as electric vehicles and a method for operating such a charging station.
  • Mobile electrical consumers such as electric vehicles with an exclusively electrical energy supply or vehicles with so-called hybrid drives usually have accumulators to supply electric drive motors with electrical energy. Since the electrical energy stored in the accumulators is used up while driving, the vehicles must be constantly supplied with new electrical energy to recharge the exhausted accumulators.
  • Such a charging station or charging column normally has a standardized connection, which can be designed, for example, as a charging cable with a connecting plug arranged at the end or as a charging socket or as a socket with defined connection dimensions.
  • a further aim of the invention can be seen as proposing an improved and simplified method for carrying out service and/or maintenance work on such an improved charging station, with this improved and simplified method also focusing on largely avoiding difficulties caused by calibration law.
  • the present invention proposes a charging station for mobile electrical consumers with the features of independent claim 1, wherein this charging station according to the invention can be used in particular for charging battery-operated electric vehicles, which have an electrical coupling point and an electrical connection connected to it Connecting line can be coupled to the charging station.
  • the term charging station used here can mean almost any type of spatially localized connection and transfer point that can fulfill the intended purpose of the controllable transmission of electrical charging energy to mobile units such as vehicles or the like, the charging station being particularly free-standing or a charging station assigned to a building can be implemented.
  • the charging station comprises at least one charging module, which is located between an electrical energy supply, in particular between a publicly accessible energy supply network or a separate long-distance line network, and the coupling point that can be coupled to the electrical consumer.
  • the at least one charging module has at least the individual components listed below and suitably interconnected.
  • the at least one charging module comprises a counting device for detecting a charging current flowing when an electrical consumer is connected. This counting device is necessary in order to record the amount of energy transmitted and to be able to provide a database for billing and cost allocation of the transmitted packets of electrical energy to the connected consumer.
  • the at least one charging module comprises a controllable output interface that is in electrically conductive connection to the coupling point.
  • This output interface can already form the connection socket into which a cable can be plugged in to begin the respective charging process.
  • controllable output interface can also mean an internal transfer point to an external electrical coupling point.
  • the at least one charging module includes a switchable separation unit located between the counting device and the output interface, which, for example, enables a remote-controlled release or interruption of a charging process, the term remote control used here meaning both control via one of the Input terminal assigned to the charging station as well as a radio transmission-based or other wirelessly transmitted control input can mean.
  • the charging module comprises a central control module, which is in control and/or data processing communication connection with the counting device, with the controllable output interface and with the switchable separation unit, the central control module having at least one spatially assigned to the charging station and/or one spatially from the
  • the charging station has an input and/or display terminal that is separate from the charging station and is in communication with the central control module via a remote data connection.
  • the term input and/or display terminal used here includes in particular any conceivable or sensible variant of user interface, for which the term human-machine interface (abbreviated: MMS or HMI for Human Machine Interface) has also become established.
  • the special feature of the charging module which forms a central and important part of the charging station according to the invention, is that the charging module, together with its components described above and possibly other components, are spatially and functionally combined within the charging station and separated from other components within the charging station. In this way, it is possible to view the charging module as a structural unit and to handle it as a unit from a calibration perspective.
  • the charging module is structurally and functionally encapsulated within the charging station and protected against interference and manipulation. This also includes, and it follows from this, that the charging module can be inserted into the charging station as a whole and removed from it as a whole, while maintaining protection against interference and manipulation, without the charging station otherwise having to be impaired or influenced in any way.
  • the input and/or display terminal which is in communication connection with the central control module and forms a user interface (HMI), can in particular be a component of the charging module and be structurally integrated there.
  • HMI user interface
  • the input module that is in communication connection with the central control module and/or display terminal is or forms a component that is spatially distant from the charging module and is not an integral part of the charging module.
  • At least two separate and individually usable input and/or display terminals are provided at the charging station, each of which has a communication connection with the central control module of the charging module.
  • a further equipment option in the charging station according to the invention can be formed in that the central control module of the charging module is assigned an input or reading device, in particular an RFID reader for processing authentication data of a user of the charging station, the input or reading device in particular being an integral part of the charging module and structurally there is integrated.
  • legal regulations may make it necessary to connect the input or reading device or the RFID reader and the input and/or display terminal (also referred to as HMI) to the charging module, in particular by Formation of an inseparable unit with the loading module.
  • the calibration regulations make it necessary to provide such a unit. This means that in order to be able to implement a design of the charging module that complies with calibration law, it is currently necessary to design both the input module and the display module as inseparable components of the charging module.
  • the above-mentioned central control module of the charging module can optionally have a data interface for data communication with a remote communication partner, wherein the data interface can be assigned a device for authentication and/or for signing the exchanged data. It makes sense for data communication to be implemented via a stand-alone communication unit.

  • the insert housing of the charging module can preferably be sealed and/or sealed to prevent tampering and tampering, which ensures that the entire charging module conforms to calibration law as a replaceable component of the charging station.
  • the present invention essentially aims to use the practical experience of recent years in the operation, maintenance and repair of charging stations or charging columns and to improve and optimize the structure and construction of the individual charging stations or charging columns to the extent that any Service work can be made easier and recommissioning can be made easier after service, maintenance or repair work has been successfully carried out. It has turned out that the calibration requirements and regulations in particular can lead to difficulties and in many cases, even after minor service work, a new calibration is necessary, which would not be necessary in all cases for technical reasons. However, as soon as the structure of the calibrated components is intervened and, for example, a housing section is opened and/or an individual component is replaced, a new calibration must be carried out, since the intervention often no longer guarantees that there will be no manipulation.
  • the charging station according to the invention with the at least one charging module designed according to the above combination of features eliminates the identified disadvantages and helps to reduce downtimes and can overall ensure a significant reduction in the identified disadvantages and risks in that the charging module essentially combines the entire charging line and therefore also as an independent one and self-contained modular unit is suitable for handling, placing on the market and exchanging for similar charging modules.
  • the charging train and the charging control makes sense to combine at least all of the above-mentioned components of the charging train and the charging control in a common module housing, which makes it possible, as an essential step, to seal this common module housing of the charging module and thus secure it by calibration, which ensures closure and security against interference, manipulation or changes by third parties.

  • the charging module combines the charging connection for the mobile consumer, especially for an electric vehicle to be charged (e.g. Type2 socket or fixed cable), the necessary fuses, a disconnecting relay, if necessary an RFID reader, and the entire charging control in accordance with EN-61851 Human-machine interface (HMI) and the meter that complies with calibration law.

In this way, the calibration regulations can be adhered to at any time and the charging modules can be easily replaced and put back into circulation again and again.
  • Communication with third-party systems can, for example, take place in such a way that a communication system is integrated into the charging station.
  • This communication system preferably converts the transaction data provided by the loading module into the operator's respective target format and forwards this data to the operator's system via the selected interface.
  • the communication module can be connected either to just one charging module or, if necessary, to several charging modules. If no communication module is used, the transaction data must be downloaded from the loading module using the software provided.

At this point it could be added that the operator of the charging stations no longer has any influence on the further use of the data by a higher-level operator or in the backend system, but this is due to the logging option for the data packets that leave the charging station and the charging modules. does not have to mean any disadvantages.
