Description

The present invention relates to a method for electrically charging an electric vehicle, a related device and a related electromobile.

Although first motor vehicle electric vehicles are manufactured in series, the development of such electric vehicles is far from mature. In particular, the electric charging of electric vehicles presents developers as well as users of these electric vehicles with challenges that are no longer known in motor vehicles with internal combustion engines nowadays. Both the charging infrastructure and the range of electric vehicles does not correspond approximately to the comfort known from motor vehicles with internal combustion engines.

Currently, it is very limited for the user of a scooter to charge his vehicle outside his own living environment.

Therefore, it would be desirable to provide a way to further simplify and / or flexibilize the electric charging of an electric vehicle.

It is an object of the invention to propose an electric charging device which is simpler and / or more flexible for the user of an electromobile and which avoids or at least reduces at least some of the disadvantages known in the prior art.

The object is achieved by a method according to the main claim, and by means of two devices according to independent claims.

The subject of the main claim relates to a method for electrically charging an electric vehicle, preferably for electrically charging an electric motor vehicle, the method comprising: determining at least one charging location with a limited charging capacity. Displaying a charging price and the charging capacity for each determined charging location, wherein the charging capacity of the charging location corresponds to a maximum amount of electrical energy to be delivered. After selecting the loading location and starting the selected loading location with the scooter: initiate a charging from the appropriate charging location to the scooter. Charging the scooter with a charge energy amount, the amount of charge energy corresponds to a maximum of the corresponding amount of electrical energy to be delivered. Further debit or charge the corresponding loading price for the amount of energy.

An electric vehicle in the sense of the invention can be a vehicle with an electric drive. In particular, an electric vehicle may be a two or more-wheeled electric motor vehicle, such as a two-wheeled motor vehicle, a passenger car, a bus, a truck, and the like.

An electric charging of an electric vehicle in the sense of the invention means the charging of one or more installed in the electric vehicle electric rechargeable energy storage, such as an accumulator, so for example a rechargeable battery, in particular such electric rechargeable energy storage, for the operation of the electric drive of the scooter needed. Such an electric drive can be realized for example by means of one or more electric motors for the wheel drive of the scooter.

A loading location in the sense of the invention may be a geographical location, at which a corresponding charging facility for the electric vehicle is kept. A loading location to be approached can be selected automatically, for example, according to predefinable criteria such as loading price, distance, maximum load and other criteria. A loading location to be approached can also be selected manually by the user of the electromobile.

A limited charging capability in the sense of the invention can be a charging option which provides electrical energy only to a limited extent. In particular, this can be a charging option, which does not receive its charge energy amount to be delivered at the time of delivery from a public or private power grid. The maximum amount of charge energy to be delivered can be identifiable.

A debiting or invoicing within the meaning of the invention may be a payment or billing process that allows the operator of the charging a corresponding remuneration for the amount of charged energy.

The teaching according to the invention achieves the advantage that the electric charging of an electric vehicle is simplified by providing charging locations that are flexible and individual, which can be selected and approached and which ensure that a corresponding amount of charging energy is available.

The subject of a first independent claim relates to a device for a scooter, the device comprising a visualization means, a selection means and a Means of communication. The visualization means is set up to visualize charging locations for charging the electric vehicle with electrical energy. The selection means is set up to select a loading location from the set of visualized loading locations. The communication means is adapted to receive loading locations. And the device is adapted to carry out any method according to the invention.

The teaching according to the invention achieves the advantage that the electric charging of an electric vehicle is simplified in that charging locations can be displayed which can be selected and approached and which ensure that a corresponding amount of charging energy is available.

The subject matter of a further independent claim relates to an electric vehicle, preferably an electromobile motor vehicle, comprising any device according to the invention.

The teaching according to the invention achieves the advantage that an electric vehicle can be provided with which the electric charging of this electromobile is simplified by displaying loading locations which can be selected and approached and ensuring that a corresponding amount of charging energy is available ,

Before describing embodiments of the invention in more detail below, it should first be noted that the invention is not limited to the described components or the described method steps. Furthermore, the terminology used is not a limitation, but has only exemplary character. Insofar as the singular is used in the description and the claims, the plural is also included, unless the context explicitly excludes this.

Hereinafter, further exemplary embodiments of the method according to the invention will be explained.

According to a first exemplary embodiment, the method further comprises that the charging process is wireless.

A wireless charging in the context of the invention means a charging process, which can take place wirelessly, for example via induction.

This embodiment has the advantage that the charging process can be made particularly simple without the user of the electromobile to be charged having to first establish a wired connection between the electromobile to be charged and the charging location.

According to a further exemplary embodiment, the method further comprises that the loading price for the loading location can be predetermined by a provider of the loading location.

This embodiment has the advantage that it is already known before the start of the charging location, which costs may arise for the charging of the scooter. Thus, the user of the scooter can be provided a way to go to the least expensive charging location for charging. This can also be done automatically, for example, without explicit user selection.

According to a further exemplary embodiment, the method further comprises that upon debiting of the corresponding loading price for the corresponding amount of charging energy debiting by means of a micro-payment payment method is vornehmbar.

A micro-payment payment method in the sense of the invention can be a payment method, which allows simple payment of small amounts of money, for example via a payment provider. In particular, this can be a mobile-based payment method, as can be made possible for example by means of a so-called smart technology such as a smart phone, a smart pad, a smart watch or smart glasses. Such smart technology-based terminals may be, for example, an iPhone, an iPad, an iWatch, a Google glasses and the like. However, it may also be devices that are installed directly in the scooter and, for example, can make the micro-payment payment via a SIM card or terminals which are incorporated in the clothing of the user and, for example, the micro-payment over a payment Sim card can make.

This embodiment has the advantage that it can be possible to provide a particularly simple payment method for the settlement of the amount of energy consumed.

According to another exemplary embodiment, the method further comprises that the loading location is a non-commercial loading location.

A non-commercial loading location in the sense of the invention can be a loading location which can be provided by non-professional providers.

This embodiment has the advantage that it can be possible to considerably expand the charging possibilities in which private persons, clubs, public institutions and other non-commercial providers can provide loading locations.

According to a further exemplary embodiment, the method further comprises that the loading location is an electromobile parking space.

An electric scooter parking space according to the invention may be a charging location, on which, for example, an electric vehicle is ready, which is currently not used and by means of which rechargeable energy storage a limited amount of energy for charging a further electric vehicle is available. For example, it may be possible for a first user of a first electric vehicle to park his electric vehicle on a parking space and to decide that he does not need a certain amount of available energy of the first electric vehicle and wants to hand it over. For this he provides the first electric vehicle as a loading location. A second user of a second electric vehicle can now approach this charging location and charge the second electric vehicle accordingly.

This embodiment has the advantage that it can be possible to further expand the charging possibilities even further, in that in principle any parked electric vehicle can act as the charging location.

According to a further exemplary embodiment, the method further comprises that the loading location is a mobile loading location.

A mobile loading location in the sense of the invention means a loading location which is mobile and thus movable. This may be, for example, a loading location that is locally movable, such as an electric vehicle, which is only for a short time, such as in a traffic jam or slow-moving traffic or at a traffic light or train gate. For example, a user of an electromobile could be set to release as a mobile loading location each time a certain marginal speed, such as walking speed, is reached or undershot.

This embodiment has the advantage that it is also possible to charge a scooter during short service lives and / or at slow speeds, as a result of which the charging locations can be further increased and the electric charging of an electric vehicle can be made even more flexible.

According to a further exemplary embodiment, the method further comprises that the charging location is an electric vehicle.

In contrast to an electric scooter parking place as a charging location my electric scooter as a loading location that the scooter itself released as a loading location, so can be made available. This makes it possible, for example, to provide electric vehicles specifically as loading locations. In this case, it is possible, for example, for an electric vehicle, for example an autonomous electric vehicle, to be requested as a loading location and to drive against the requesting electric vehicle in order to charge it.

This refinement has the advantage that an electromobile can itself be a charging location and thus an even more flexible electrical charging possibility of an electromobile can be made possible.

According to a further exemplary embodiment, the method further comprises that the maximum amount of electrical energy to be delivered at the charging location can be determined based on an energy consumption behavior of the electromobile which functions as a corresponding charging location.

This refinement has the advantage that the maximum amount of energy to be delivered can be determined flexibly in order to ensure that the electromobile, which functions as the charging location, still has sufficient electrical energy for a future journey.

According to a further exemplary embodiment, the method further comprises that the maximum amount of electrical energy to be delivered at the place of loading can be determined by the provider of the corresponding loading location.

This embodiment has the advantage that the provider of the corresponding charging location can independently determine what amount of energy he would like to make available for acceptance by an electric vehicle to be charged.

According to a further exemplary embodiment, the method further comprises that the maximum amount of electrical energy to be delivered at the place of loading can be released by the provider of the corresponding loading location.

A release of a maximum amount of electrical energy to be dispensed within the meaning of the invention means that the provider of the corresponding loading location itself must make a release.

This embodiment has the advantage that a provider of the corresponding charging location must make the release of the maximum amount of electrical energy to be dispensed independently, and thus can not be prevented by the provider provided removal of electrical energy at its charging location.

Hereinafter, further exemplary embodiments of the device according to the invention will be explained.

According to a first exemplary embodiment, the device further comprises that the communication means is adapted to allow a debit of the corresponding charge price for the corresponding amount of charge energy at the selected charging location.

This embodiment has the advantage that an accounting of the loading price can be made possible directly at the place of loading.

According to a further exemplary embodiment, the device further comprises that the debiting of the corresponding charge price by means of a micro-payment payment method is vornehmbar.

This embodiment has the advantage that it can be possible to carry out the billing by means of the device itself.

The invention thus makes it possible to approach different types of charging by means of an electric vehicle to be charged electrically and to remove electrical energy according to the specifications at the place of loading.
