Description

The present invention relates to a communication system for an electrically operated device, in particular for an at least partially electrically powered vehicle having an electrical storage, which is rechargeable from a power grid, being provided via the mains electric current with a current mix, and wherein the power mix a percentage distribution of the energy carriers, from which the electric current is generated.

STATE OF THE ART

In addition to vehicles with gasoline and diesel engine increasingly vehicles are operated in traffic, having a fully electric or at least a partially electric drive. The vehicles with a part-electric drive are also referred to as hybrid vehicles and can switch between a gasoline engine or a diesel engine and an electric motor. If these vehicles are operated, for example, on highways, the gasoline engine or the diesel engine is used. If the vehicles are operated in metropolitan areas or inner cities, the drive can be switched to the electric drive. For operation of the electric drive, the vehicle has an electrical storage, which is designed as an accumulator and which provides the electric current for operation of the electric motor. To charge the electric storage, it is periodically connected to the public power grid, and the electric storage can be charged.

The electrical power provided via the power grid has a power mix, the power mix describing a percentage distribution of different energy carriers from which the electric power is generated. The energy carriers may, for example, relate to fossil fuels, nuclear energy or regenerative forms of energy, for example wind energy, water energy or solar energy. The electricity mix with a different distribution of energy carriers can be different in time and locally. Furthermore, various industrial suppliers of electricity are known, and the electricity mix can also have a different distribution of energy carriers, depending on the commercial supplier.

In principle, it is desirable to feed electrically operated devices such as an electrically operated vehicle with a power mix that has the highest possible ecological quality. Fossil fuels, for example, have only a low ecological quality compared with regenerative energy sources, for example by the release of carbon dioxide when fossil fuels are used. Although nuclear energy is characterized by little or no carbon dioxide release, nuclear energy is also classified as low in ecological quality, since there is a residual risk in the operation of nuclear power plants and radioactive waste, which causes a bearing problem , It follows that a power mix with a different distribution of energy sources results in a different ecological quality. This results in the requirement to load the electrical storage of the electrically operated device with a power mix of high ecological quality.

From the DE 10 2008 040 030 A1 is a driver information system is known, which allows in the form of a navigation system, a route calculation and thus a route guidance of the vehicle, for example, to a destination. In this case, map data are used for the guidance and route calculation of the route guidance, wherein the map data contain selected zones which have specific properties with regard to their passage through, for example, requiring pass-through permission rights. As a result, the existence of special zones and / or the so-called environmental zones defined in Germany is taken into account, in particular taking into account a corresponding permission to drive of the vehicle used in the control of the vehicle and / or for route calculation and / or destination guidance. If a driver of a vehicle is not allowed to drive through a zone with his vehicle due to the environmental compatibility of the vehicle, or only for a corresponding fee, the navigation system may provide the route planning in such a way that the forbidden or paid zone is not passed through.

This creates the disadvantage that the environmental compatibility of the vehicle forms a constant, which depends on the technical design of the vehicle. For example, the vehicle may belong to a specific year and meet, for example, a specific Euro emission standard. It is known to mark the vehicles, for example, with green, yellow or red badges. However, a regular recording of the environmental compatibility of the vehicle in the environmental zones is not known. The marking of the vehicles is only of regulatory relevance, so that the control of the environmental compatibility of the vehicle is only controllable by a regulatory person.

Due to the increasing share of at least partially electrically powered vehicles, the electric drive in the vehicle is characterized by a very high ecological quality, However, the environmental impact shifts to the provision of electrical energy, and thus to the electricity mix with a specific distribution of energy sources of different ecological quality. A control device with which to control the ecological quality of the operation of at least partially electrically operated vehicles is not known.

It is therefore the object of the present invention to further improve the environmental impact of electrically operated devices, in particular at least partially electrically powered vehicles.

This object is achieved on the basis of a communication system for an electrically operated device according to the preamble of claim 1 in conjunction with the characterizing features. Advantageous developments of the invention are specified in the dependent claims.

DISCLOSURE OF THE INVENTION

The invention includes the technical teaching that the electrically operated device has a communication interface, via which the current mix of the electrical current with which the electrical storage is charged, can be communicated.

The invention is based on the idea that the current mix of the electric current with which the electrical storage has been charged can be communicated with a location external to the device. The electrically operated device may be an at least partially electrically operated vehicle, however, the electrically operated device may represent any type of device having an electrical memory and through which the device is electrically operated, such as electric buses, construction machinery or other stationary or mobile devices for household or trade. Through the communication interface of the power mix can be queried in the electrical memory, wherein the communication interface is further adapted to also communicate when charging the electric power from the power grid, the power mix.

Advantageously, an external receiver device is provided with which the current mix in the electrical memory of the electrically operated device can be communicated via the communication interface. The external receiver device can be provided both to query the current mix in the electrical memory as well as for sending the data on the power mix, when the electrical storage is charged. For this purpose, the electrical device may have a data memory.

Advantageously, the electrical device may comprise a data memory in which data about the current mix supplied to the electrical memory can be stored. Furthermore, the electrically operated device can have a data memory in which data about the current mix of the current can be stored, which results from an electric charge already present in the electrical storage and a charge currently added. This results in a new division of the energy sources of the power mix in the electrical storage, when the power mix, which is already present in the electrical storage as a residual charge, a mixture results, with the current mix of the current that is used to recharge the electrical storage. Consequently, the data can be transmitted with the external receiver device via the power mix both to the data memory and queried by this.

According to an advantageous embodiment of the invention, the communication interface can be based on an air interface, in particular on a GSM technology or on a WLAN technology. If the electrically operated device is connected to the public power grid, for example via a charging cable, a communication between a transmitting device and the communication interface of the electrically operated device can be established at the same time. The communication can for example be based on a GSM technology or, for example, on a WLAN technology or the communication also takes place via the charging cable of the power grid. For example, it is known to modulate a power network with a signal, so that in addition to the power transmission, a signal transmission can take place. If the communication interface of the electrically operated device receives data via the power mix, then this data can be stored in the data memory of the electrically operated device. The data stored in the data memory via the power mix can subsequently also be interrogated via the communication interface of the electrically operated device with the external receiver device. If the data about the current mix in the electrical memory of the electrically operated device has been interrogated by the external receiver device, these can even be stored on an external server according to a further advantage.

With further advantage, the electrically operated device can have a display device with which data about the current mix in the electrical memory of the electrically operated device can be displayed. Especially in a vehicle can a display device in the cockpit of the vehicle be present, and the driver can query the current power mix or even the history of the power mix via the display device. With further advantage, the external receiver device may be part of an external interrogator, in particular for interrogating data from vehicles in traffic, with the data on the power mix in the electrical memory of the electrically operated device are queried, especially if the vehicle moves in traffic at the interrogator over becomes.

Furthermore, the interrogator may be provided for interrogating data on the power mix in the electrical memory of the electrically operated device at retraction areas of predefined zones, wherein the entry of the vehicle into the zone is preferably only approved or is free if the electricity mix a high ecological quality having.

With still further advantage, the electrically operated device can be designed as a vehicle with a navigation system, wherein the navigation system is designed in a route planning to take into account the permissibility of the entry into a zone.

The display device in the vehicle can be designed as a head unit, and data about the power mix can be displayed to the driver with the head unit when it enters special traffic zones. The query of the current power mix is done either via the interrogator and thus via an external server after the vehicle has been identified, but the query can also be made directly from the vehicle and is transmitted for example via a car-to-infrastructure or Bluetooth. The queried information about the current power mix can be used, for example, to determine, for example, a toll on the basis of the electricity mix used or to deny entry into certain traffic zones. The navigation system may in particular be designed to exclude certain zones in which the vehicle with an existing power mix that does not reach a minimum ecological quality, in the route planning. The exclusion of certain traffic zones can be automatic or manual by informing the driver of the limitations of certain traffic zones and making an entry through the display device, for example to allow a paid entry or avoid the paid traffic zone. Thus, a system is created based on the ecological quality of the electricity mix entitles or denies or raises costs when a vehicle does not meet a required ecological quality, the communication of the ecological quality on the communication system is queried.

The object of the present invention is further achieved by a method for communication of data via a communication system for an electrically operated device, in particular for an at least partially electrically operated vehicle having an electrical storage that is charged from a power grid, wherein via the power grid electric power is provided with a power mix, and wherein the power mix has a percentage distribution of the energy sources, from which the electric current is generated. It is provided that the electrically operated device has a communication interface, via which the current mix of the electric current with which the electrical storage is charged, is communicated.

According to a further embodiment of the method, an external receiver device is provided with which the current mix in the electrical memory of the electrically operated device is communicated via the communication interface, wherein the external receiver device is part of an external interrogator, in particular for interrogating data of vehicles in traffic, be queried with the data on the power mix in the electrical memory of the electrically operated device, especially when the vehicle is moved past the interrogator in the traffic.

According to an advantageous embodiment of the method, the interrogator is provided for retrieving data about the power mix in the electrical memory of the electrically operated device at Einfahrbereichen of zones, the entrance of the vehicle is preferably only approved in the zones when the power mix a high ecological quality having.

The method describes the charging of the electrical memory of the electrically operated device, wherein at the same time data on the power mix are transmitted from a transmitting device via the communication interface to a data memory in the electrically operated device. If the vehicle is operated, these data can subsequently be queried as often as desired and at different locations via external receiver devices from the data memory of the electrically operated device via the communication interface. Based on the queried data by the external receiver device, for example, a taxation of the electrically operated device or other cost collection can take place, wherein preferably the costs are set particularly low when the Electricity mix, with which the electrically operated device is operated, has a high ecological quality.
