CHARGING SYSTEM FOR DYNAMIC CHARGING OF ELECTRIC VEHICLES

Description

Field of invention

[0001] The invention relates to a charging system for the dynamic charging of electric vehicles with a corresponding software application and a corresponding method, as well as a data storage product with a software application stored thereon. Background of the invention

[0002] To meet the energy needs of electric vehicles, charging stations are used to provide the necessary electrical energy. With the increasing number of electric vehicles and the desire for improved mobility, especially for long-distance journeys, the problem arises that different users with varying charging requirements must visit charging stations that may be located far from their planned route. Furthermore, the charging capacity or availability of charging points at these stations may be exhausted due to high customer demand, necessitating detours without the electric vehicle's battery being depleted. Document US 2015 / 0298565 A1 discloses a charging support system and a corresponding method for assisting the charging of an electric vehicle, designed to prevent electric vehicles from running out of battery power and becoming stranded before reaching their destination.A control center monitors the charging status of a large number of electric vehicles and, when the charging status is low, sends a request to drive to a fixed charging station located at a specific point and guides the electric vehicles to a suitable charging station, taking into account the characteristics of the charging station (number of vehicles, amount of energy available, expected customer traffic, etc.) when selecting the charging station.

[0003] While this prevents electric vehicles from being stranded due to a depleted battery during long-distance journeys, it would be desirable to have a charging system for electric vehicle batteries that takes into account the individual needs of the electric vehicle driver along their route and charges the vehicles as efficiently as possible. WO 2018 / 021573 A1, WO 2017 / 209736 A1, and US 2012 / 203409 A1 each disclose a charging system for the dynamic charging of electric vehicles comprising a software application installed and executed on at least one mobile device that includes a navigation function or is connectable to a navigation device, and / or on at least one server, and mobile charging vehicles with charging units and a navigation device. Summary of the invention

[0004] It is therefore an object of the invention to provide a charging system for charging an electric battery which is designed to take into account the individual needs of the driver of the electric vehicle along his route and to enable effective charging of the electric vehicle.

[0005] This task is solved by a charging system for the dynamic and simultaneous charging of multiple electric vehicles, comprising a software application installed and executed on at least one mobile device that includes a navigation function or is connectable to a navigation device, and / or on at least one server, and a multitude of mobile charging vehicles, each with multiple charging units and each with a navigation device designed, among other things, to transmit a current position of each mobile charging vehicle of the charging system to the software application, wherein the software application is designed toThe mobile device located in an electric vehicle is to display at least the nearest mobile charging vehicle and, in the case of the electric vehicle's battery requiring charging, to transmit a charging request for this electric vehicle as well as at least a current position of the electric vehicle to the displayed mobile charging vehicle, wherein the charging vehicle's navigation system is configured to transmit, based on the received charging request, the coordinates of a suitable common meeting point and a suitable meeting time for charging the electric vehicle's battery to the mobile device in the electric vehicle to be charged, wherein the software application is configured to translate the meeting point and meeting time into navigation instructions for a driver of the electric vehicle to be charged.

[0006] Based on the position of both vehicles (mobile charging vehicle and electric vehicle to be charged) and the agreed-upon meeting point, dynamic charging is enabled. Both vehicles move from their respective starting positions to the meeting point, thus dynamically reaching an efficient location. This saves time and resources for the electric vehicle being charged and its driver compared to a stationary charging station. The nearest charging vehicle can be displayed on a map, such as on a mobile device, using a corresponding symbol or marker, or by providing coordinates or addresses to which the vehicle must be driven. Transmitting the agreed-upon meeting point can serve as implicit confirmation of the charging order for the electric vehicle, as requested.However, an order confirmation can also be explicitly sent from the loading vehicle to the software application on the mobile device.

[0007] The term "electric vehicle" refers to all vehicles with an electric motor, including hybrid vehicles with additional motor types. The term "charging vehicle" refers to vehicles that include an energy reservoir for conversion into electrical energy and can therefore provide this electrical energy at any location to charge a vehicle battery for powering an electric vehicle. For example, such charging vehicles can be trucks with appropriate equipment. These charging vehicles can be powered by an electric motor themselves, but can also include other motor types such as combustion engines, hybrid engines, or other motors for their own propulsion. The navigation system of the mobile charging vehicle determines both its current position and calculates the rendezvous point.The navigation system can, for example, be a navigation system with enhanced functionality. The meeting time may be affected by other electric vehicles still charging at a previously agreed-upon meeting point, as the charging vehicle cannot immediately depart for the new meeting point in such cases. Provided the charging request is transmitted sufficiently early, this does not pose an obstacle to the meeting point itself, but at most influences its location, potentially shifting it further along the planned route of the electric vehicle being charged, closer to its destination.

[0008] The term "software application" refers to application software (also called application program, or simply application (APP)), which is a computer program used to perform or support a useful or desired non-system-related functionality. Mobile apps (on mobile devices) can, for example, be obtained from an app store integrated into the mobile operating system and installed directly on the device. Mobile web apps can be accessed via the mobile device's web browser. Installation refers to the installation of the software application on the mobile device itself or on an interface for using the corresponding application program via a website. Execution of the software application refers to its execution by the mobile device's processor or the processing of data provided to the mobile device via the interface of a web app.

[0009] The term "mobile device" refers to a device designed to establish a wireless or internet connection with other devices and equipped with a display screen. Examples of such mobile devices include smartphones, tablet PCs, laptops, digital communication devices, and navigation devices on which software applications can be installed and run. Specifically, this could be an iOS or Android smartphone, a device installed in the vehicle such as an Android device, and / or the vehicle's media system. The navigation function of the mobile device enables the navigation instructions generated by the software application to reach the appropriate meeting point to be converted into a navigation route to the meeting point, which the driver can then use to drive to the meeting point with the delivery vehicle.Alternatively, the mobile device can be connected to a navigation system, whereby the navigation instructions from the software application are processed by the navigation system in the electric vehicle into a corresponding navigation route via suitable interfaces. If the mobile device is located on board an electric vehicle, its position is identical to the electric vehicle's position. Thus, the electric vehicle's position information can be either the current position of the mobile device or the current position of the electric vehicle from a navigation system located on board, transmitted via the mobile device to the charging vehicle.

[0010] The dynamic charging system according to the invention thus enables effective charging of the electric vehicle, taking into account the individual needs of the customer of the electric vehicle and, in contrast to the prior art, does not consider the charging process exclusively from the perspective of the locally fixed charging station, but combines the conditions of the mobile charging station with the position and charging situation of the electric vehicle and, if applicable, its movement data to create a more effective charging process for the electric vehicle compared to the prior art.

[0011] In one embodiment, the software application generates the navigation instructions for the electric vehicle, based on the meeting point and time, only after the charging request has been confirmed to the charging vehicle via the software application. This allows the electric vehicle driver to first check whether the meeting point and time are acceptable for them and their vehicle's charge level. If not, the electric vehicle can continue its route and, after being shown another mobile charging vehicle available at a later time, accept the charging offer from that vehicle. This gives the charging system greater flexibility for the electric vehicle driver, allowing it to better meet their needs.

[0012] Furthermore, data exchange between the server and the mobile device and / or data storage and / or data exchange within the software application can be carried out, at least partially, using Distributed Ledger Technology (DLT), in particular a blockchain system. This increases security due to better protection against data loss and / or additional data encryption.

[0013] In a further embodiment, the common meeting point and meeting time are determined by the navigation system of the mobile charging vehicle, taking into account at least one previous route of the electric vehicle to be charged. The software application transmits the previous route, along with the charging request, to the mobile charging vehicle using appropriately recorded position data. By considering the previous route, the driving behavior of the electric vehicle, such as current speed, previous average speed, and the resulting predicted future direction of travel, can be used as a basis for calculating a suitable common meeting point. This results in even less disruption to the electric vehicle's route for the desired charging than if only the electric vehicle's current position at the time the charging request is transmitted were used.The previous route can be retrieved by the software application from a navigation device connected to the mobile device, or it can be recorded by the software application itself based on an existing navigation function in the mobile device, for example, based on the temporal sequence of GPS data that the mobile device determines itself using a GPS module.

[0014] In another embodiment, the software application transmits not only the existing route but also the route planned for the electric vehicle up to a destination to the charging vehicle. The charging vehicle's navigation system then takes this planned route into account to calculate the meeting point and time. By considering this additional planned route, the meeting point and time can be even better tailored to the electric vehicle driver's needs, thus minimizing disruption to the electric vehicle's charging route. The software application can also retrieve the electric vehicle's planned route from a navigation device connected to the mobile device or provide it directly from the mobile device's built-in navigation function.

[0015] In another embodiment, the charging vehicle's navigation system automatically calculates the fastest route to the meeting point and displays it as the route in the charging vehicle. This allows the charging vehicle to reach the meeting point as quickly as possible, thus expanding the geographical area of ​​potentially suitable meeting points while taking into account customer preferences and minimizing disruption to the electric vehicle's route.

[0016] In another embodiment, the charging vehicle's navigation system transmits its current position to the software application at least periodically while en route to the meeting point. This allows for continuous monitoring until the meeting time to ensure the charging vehicle can reach the meeting point as planned. If necessary, in the event of an unplanned delay, the electric vehicle could cancel the meeting point and arrange an alternative meeting point, possibly with another mobile charging vehicle.

[0017] In another embodiment, the software application is designed to display the current position of the charging vehicle on its way to the meeting point on a navigation display in the electric vehicle. This display provides the electric vehicle driver with simple visual and therefore immediate confirmation that the agreed meeting point and time can be met.

[0018] In another embodiment, the software application is designed to display the positions of all charging vehicles, enabling the selection of a desired charging vehicle for charging the electric vehicle. Alternatively, or in conjunction with the preceding embodiments, the electric vehicle driver can also suggest a common meeting point and is therefore not dependent on the meeting point calculated and transmitted by the charging vehicle. This allows the electric vehicle driver to plan their charging stops highly efficiently in advance of their journey. For example, they can arrange a meeting point at a rest stop with the charging vehicle at lunchtime or have the electric vehicle charged on their business partner's premises during an appointment (such as a client visit), for which the software application provides the necessary functionality.

[0019] In another embodiment, the charging vehicle has an energy or battery storage capacity of more than 300 kWh and at least one DC charging unit and at least one AC charging unit. This allows all common electric vehicles to be charged. The charging vehicle can also include more DC or AC charging stations, for example, two DC charging units and two AC charging units. This allows for a shared meeting point for more than one electric vehicle, provided that the routes of the respective electric vehicles make this practical and minimally disruptive.

[0020] The billing for charging the electric vehicle can be based on the travel time to the meeting point and the charging time, each on a time basis, or on the basis of the travel time to the meeting point and the amount of energy charged.

[0021] The invention further relates to a method for the dynamic and simultaneous charging of several electric vehicles in a charging system according to the invention, comprising a software application installed and executed on at least one mobile device that includes a navigation function or can be connected to a navigation device, and a plurality of mobile charging vehicles, each with several charging units and each with a navigation device, comprising the following steps: Transmission of the current position of each mobile charging vehicle of the charging system to the software application via the charging vehicle's navigation system; display of at least the nearest mobile charging vehicle on the mobile device located in an electric vehicle via the software application; transmission of a charging request for the electric vehicle and at least a current position of the electric vehicle to the displayed mobile charging vehicle in the case of an electric vehicle battery requiring charging via the software application; transmission of the coordinates of a suitable common meeting point and a suitable meeting time for charging the electric vehicle's battery to the mobile device in the electric vehicle to be charged via the charging vehicle's navigation system, based on the received charging request;and the conversion of the meeting point and meeting time into navigation instructions for the driver of the electric vehicle being charged, using the software application to navigate the electric vehicle to the shared meeting point.

[0022] This method according to the invention thus enables effective charging of the electric vehicle, taking into account the individual needs of the customer of the electric vehicle and, in contrast to the prior art, does not consider the charging process exclusively from the perspective of the locally fixed charging station, but combines the conditions of the mobile charging station with the position and charging situation of the electric vehicle and, if applicable, its movement data to a significantly more effective charging process for the electric vehicle compared to the prior art.

[0023] In one embodiment of the method, this includes the additional step of determining the common meeting point and the meeting time, taking into account at least one previous route of the electric vehicle to be charged from the navigation device of the mobile charging vehicle, wherein the software application has transmitted the previous route to the mobile charging vehicle together with the charging request, based on correspondingly recorded position data.

[0024] In another embodiment of the method, the software application transmits the route planned for the electric vehicle up to a route destination to the charging vehicle in addition to the existing route, and the navigation device of the charging vehicle takes the planned route into account to calculate the common meeting point and the meeting point time.

[0025] In a further embodiment of the method, this includes the additional step of at least periodically transmitting the current position of the charging vehicle on a route to the common meeting point by the navigation device to the software application for a query in the electric vehicle.

[0026] In a further embodiment of the method, this includes the additional step of displaying the current position of the charging vehicle on the way to the common meeting point by the software application on a navigation display in the electric vehicle.

[0027] In another embodiment of the method, the software application displays all positions of all charging vehicles to enable the selection of a desired charging vehicle for charging the electric vehicle, followed by the selection of one of the displayed charging vehicles as the charging vehicle for charging the electric vehicle's battery.

[0028] In another example of the process, the software application suggests a meeting point and / or a common meeting time to the charging vehicle, which the vehicle then accepts as the agreed meeting point and time. The suggested meeting point or time can be entered into the mobile device by an operator, such as the electric vehicle driver, using the software application's input form. The desired meeting point can be entered, for example, by specifying the coordinates or by marking a point on a map-style input form.

[0029] Furthermore, a data storage product can be implemented with a software application stored on the data storage product suitable for executing the steps of the dynamic charging procedure related to the software application.

[0030] Data storage products can be any data storage device suitable for storing software programs such as software applications, for example, USB drives, CDs, hard drives, servers and other suitable devices.

[0031] The embodiments of dynamic charging listed above can be used individually or in any combination to design the device for dynamic charging and the method for dynamic charging according to the invention.

[0032] It is evident that the digital access system can support dynamic charging by granting the charging vehicle, and in particular an occupant such as a driver, service personnel, or other employee, access to the electric vehicle for charging the energy storage system or battery. For example, a charging flap can be opened for charging the electric vehicle. To do this, the activation unit transmits data to the charging vehicle or the occupant to activate the unlocking unit, at least for a certain period of time.

[0033] The activation of the unlocking unit can be carried out in particular as follows.

[0034] Key components include the software application that interacts with the vehicle being charged. This software application is primarily a server-based application that evaluates incoming information from the vehicles being charged and / or the charging vehicles, controls the charging vehicles, defines meeting points, and / or handles billing.

[0035] Interaction with the vehicle to be charged can be achieved by having the software application partially installed on a mobile device and / or by having a mobile application connected to the software application installed and running on a mobile device, in particular by providing access to necessary vehicle data via an OBD2 interface of the vehicle.

[0036] Preferably, communication between the parts of the software application installed on the server and the mobile device, in particular the forwarding and storage of the data necessary for controlling access to the vehicle to be charged, the charging of the vehicle to be charged, and the billing of the charge, takes place using DLT, especially via a blockchain application. This establishes multiple layers of redundant security for all regulatory, contractual, and billing processes, which, however, remains transparent to all partners within the defined scope.

[0037] For example, the mobile device or mobile application receives all essential information from the vehicle to be charged via the OBD2 interface, such as driving style, charging capacity and state of charge of the battery, temperature and position.

[0038] Furthermore, the part of the software application running on the mobile device, or the mobile application itself, knows the destination, if necessary the parking space of the vehicle to be charged, has access to navigation data and traffic conditions, and is connected to the internet.

[0039] The software application calculates when and where the vehicle to be charged needs to meet a charging vehicle and how much electrical energy is required.

[0040] Distributed ledger technology (DLT), specifically blockchain technology, is used to transmit and store the relevant data on the server. The server, which monitors the vehicles to be charged and the charging vehicles themselves, uses the DLT / blockchain to confirm the arrival of the vehicle to be charged and the planned meeting point to the software application running on the mobile device or the mobile application. These details are not static, however, and can be adjusted based on changes detected by the software application and / or the mobile application.

[0041] The software application also receives data that enables the charging vehicle to access the vehicle to be charged via the access system. This can be done independently of the use of DLT or blockchain technology. Preferably, the data has a limited validity period, which is aligned with the planned meeting time between the charging vehicle and the vehicle to be charged. Preferably, the data only allows access a specific time before or after a calculated meeting time. The data can, for example, include a code that can only be used once. After this single use or the expiration of the validity period, the code can no longer be used to access the vehicle to be charged. The data required for access is generated or transmitted as follows.

[0042] Personal data of the individuals involved, such as movement profiles, remains as highly sensitive data within the part of the software application running on the mobile device or the mobile application in the vehicle being charged. The mobile device only transmits a customer ID and the time and location of the planned meeting point to the server. The data transmission is encrypted, particularly via distributed ledger technology (DLT) or blockchain.

[0043] A new DLT or blockchain transaction is generated for each charging process. New orders from the same customer or repeat orders also result in a new DLT or blockchain transaction. This prevents individual order data, access codes, or other data related to the charging process from being reused after the charging process is completed and the blockchain is closed. Due to the encryption provided by the DLT or blockchain, this data cannot be intercepted and misused, as it is useless for other charging or payment transactions. Thus, each charging order is unique and, thanks to the DLT or blockchain technology, cannot be altered.

[0044] Each blockchain transaction is linked to an individual order number, which can only be used to trigger a single charging process or charging order.

[0045] The server can be configured as a high-performance clustered server or as a cloud application. The server controls all charging vehicles and negotiates possible meeting points with the vehicle to be charged, based on the transmitted parameters. To this end, the software application uses blockchain technology to determine all data necessary for processing the charging transaction, compares this data with the actual conditions and possibilities, and offers the user of the vehicle to be charged an order confirmation. If the order confirmation is accepted, the data necessary for the charging process, in particular the access code, meeting point, and meeting time, are transmitted to the vehicle to be charged, the charging vehicle, and specifically to the operator of the vehicle to be charged or the operator of the charging vehicle.

[0046] Furthermore, the software application initiates and monitors the loading process. This process, particularly due to the use of blockchain technology, becomes an automated sequence after order confirmation, and is generally uninterruptible. If a loading vehicle breaks down, a new blockchain transaction is generated and then carried out with an alternative loading vehicle.

[0047] The use of DLT or blockchain offers the advantage that existing blockchain applications can be built upon, allowing not only the logistical handling of the charging process but also payment and billing processes and their formalities to be processed.

[0048] The server or software application can manage all contracts with the operators of the vehicles to be charged or the charging vehicles, bill and control all processes.

[0049] Furthermore, the server offers an interface to partners via DLT or blockchain, such as electricity providers, other providers of charging vehicles, or the fleet management of companies and organizations.

[0050] The DLT or blockchain can be implemented as an ERC20 / ERC223 solution and, in particular, can run on an existing blockchain application.

[0051] The advantage of the above is that the DLT or blockchain technology used in the charging system acts as a decentralized, multiply redundant database and also offers the possibility of carrying out and automating contract management with high security via smart contracts (electronic automatic contracts).

[0052] This makes it possible to provide an encrypted connection for exchanging the necessary data between all parties, preferably using smart contracts to regulate who has access to which data and who can view which information and how.

[0053] Settlement can preferably be carried out via proprietary tokens, which are preferably also connected via smart contracts to classic payment providers such as credit card companies, SEPA payment providers and / or providers such as PayPal.

[0054] By using DLT or blockchain technology, costs can be optimized due to the reduced hardware and software infrastructure required for processing shipments, as well as the high degree of automation and the associated reduction in manual intervention, without compromising security. Furthermore, this technology improves secure and clearly regulated communication between an unlimited number of partners. Server or cloud resources, as well as the software application or mobile application, do not need to expose any vulnerable interfaces.

[0055] Furthermore, the description includes the following figures, which are used to explain further aspects of the previously described dynamic charging system.

[0056] These and other aspects of the invention are shown in detail in the figures below. Brief description of the illustrations

Detailed description of the exemplary implementations

[0058] Fig. 1Figure 1 shows a schematic representation of an embodiment of the charging system 1 according to the invention for the dynamic charging of electric vehicles 2, comprising one or more mobile devices 3 (here, for the sake of clarity, only one mobile device in an electric vehicle 2 is shown as an example), each of which includes a navigation function or can be connected to a navigation device 22 in the respective electric vehicle 2, and a software application 4 installed and executed on the respective mobile device 3, as well as a plurality of mobile charging vehicles 5, each with a navigation device 51, which is designed, among other things, to transmit a current position P5 of each mobile charging vehicle 5 of the charging system 1 to the software application 4.The software application 4 is designed to display at least the nearest mobile charging vehicle 5 on the mobile device 3 located in an electric vehicle 2 and, in the case of an electric battery 21 of the electric vehicle 2 needing charging, to transmit a charging request for this electric vehicle 2 as well as at least a current position P2 of the electric vehicle 2 to the displayed mobile charging vehicle 5, whereby the current position of the mobile device is equated with the current position P2 of the electric vehicle 2, since the mobile device 3 is located on board the electric vehicle 2.The navigation device 51 of the charging vehicle 5 is configured to transmit the coordinates of a suitable common meeting point TP and a suitable meeting time TZ for charging the electric battery 21 of the electric vehicle 2 to the mobile device 3 in the electric vehicle 2 being charged, based on the received charging request. The software application 4 is configured to convert the meeting point TP and meeting time TZ into navigation instructions for a driver of the electric vehicle 2 being charged. The software application 4 can also generate the navigation instructions for the electric vehicle 2 based on the common meeting point TP and meeting time TZ only after the software application 4 has transmitted confirmation of the charging request at the common meeting point TP to the charging vehicle 5.In one embodiment, the software application 4 can also be configured to display all positions P5 of all charging vehicles 5 in order to enable an operator of the mobile device (for example, the driver of the electric vehicle 2) to select a desired charging vehicle 5 for charging the electric vehicle 2. Fig. 2Figure 1 shows a schematic representation of an embodiment of the electric vehicle 2 with an electric battery 21 for operating the electric vehicle 2 and with a mobile device 3 and a software application 4 according to the invention installed thereon. The software application 4 can be configured to translate the meeting point TP and meeting time TZ into navigation instructions for a driver of the electric vehicle 2 being charged, wherein the software application 4 can display the current position P5 of the charging vehicle 5 on the way to the common meeting point TP on a navigation display in the electric vehicle 2. The navigation display can be the screen of the mobile device 3 or the screen of the navigation device 22 connected to the mobile device 3 in the electric vehicle 2. For this purpose, the mobile device 3 can be connected to the navigation device 22, for example, via a cable or an interface for wireless near-field communication (e.g., Bluetooth).The software application 4 provides corresponding interfaces for data transmission to the navigation device 22. In one embodiment, the navigation device 51 of the charging vehicle 5 can, at least periodically, transmit the current position P5 of the charging vehicle 5 to the software application 4 for querying in the electric vehicle 2 on its way to the common meeting point TP, until the charging vehicle 5 has reached the common meeting point TP. Fig. 3Figure 1 shows a schematic representation of the calculation of the common meeting point TP based on position and movement data of the electric vehicle 2, as well as the routes FRE, FRL of the charging vehicle 5 and the electric vehicle 2 to the common meeting point TP. If only the current position P2 of the electric vehicle 2 is transmitted to the displayed mobile charging vehicle 5 along with the charging request, the navigation device 51 of the charging vehicle 5, without knowledge of the previous route BR and the planned future route GR of the electric vehicle 2, can only use a meeting point area TG1 (represented by a circle with a dash-dot line) around the current position P2 of the electric vehicle 2 to calculate a suitable common meeting point TP, the diameter of which is determined, for example, by the road conditions and the assumed speeds of the two vehicles 2 and 5.If, on the other hand, the common meeting point TP and the meeting time TZ are determined by the navigation system 51 of the mobile charging vehicle 5, taking into account the previous route BR of the electric vehicle 2 to be charged, a different meeting point area TG2 can be assumed, based on the assumption that the previous route will continue in approximately the same way. This is extrapolated from the previous route BR of the electric vehicle 2 into a corresponding forward movement, shown here as a teardrop-shaped area TG2 with a dashed line. A common meeting point in area TG2 disrupts the route of the electric vehicle 2 significantly less than a meeting point in area TG1 based solely on the current position P2 of the electric vehicle 2 at the time the charging request is transmitted. For this purpose, the software application 4 transmits the previous route BR, along with the charging request, to the mobile charging vehicle 5 using appropriately recorded position data.If the software application 4 transmits the route GR planned for the electric vehicle 2 to a route destination RZ to the charging vehicle 5 in addition to the existing route BR, the navigation device 51 of the charging vehicle 5 can take the planned route GR into account to calculate the common meeting point TP and the meeting point time TZ, as shown in . Fig. 3This is shown. Here, the common meeting point TP lies exactly on the planned route GP of electric vehicle 2 to the destination RZ. Therefore, the planned charging of the electric battery 21 of electric vehicle 2 does not interfere with the route BR,GR of electric vehicle 2 at all, since the common meeting point TP and the travel distance FRE of electric vehicle 2 to meeting point TP correspond to the planned route GR, and thus no detours and associated additional travel times are necessary. The navigation system 51 of charging vehicle 5 can automatically calculate the fastest route for charging vehicle 5 to meeting point TP and display it as route FRL in charging vehicle 5. Fig. 4Figure 1 shows a schematic representation of the charging vehicle 5 according to the invention, which here, in addition to the navigation device 51, has a battery storage unit 52 of more than 300 kWh and a DC charging unit 53 and an AC charging unit 54. Other charging vehicles can also have more DC and / or AC charging units 53, 54. The multiple charging units 53, 54 enable the simultaneous charging of several electric vehicles 2, each with an electric battery 21, and mobile devices 3, on which the software applications 4 are installed and executed. Fig. 5 Figure 1 shows a schematic representation of the data storage product 10 according to the invention with a software application 4 stored thereon, which is used to execute the steps of the method 100 relating to the software application 4 according to the invention. Fig. 6is suitable. Data storage products 10 can be any data storage device suitable for storing software programs such as software applications, for example, USB drives, CDs, hard drives, servers and other suitable devices. Fig. 6Figure 1 shows a schematic representation of an embodiment of the inventive method 100 for the dynamic charging of electric vehicles in a charging system according to the invention, comprising a software application 4 installed and executed on at least one mobile device 3, which includes a navigation function or can be connected to a navigation device 22, and a plurality of mobile charging vehicles 5, each with a navigation device 51. In this embodiment, the method comprises the steps of transmitting 110 the current positions P5 of each mobile charging vehicle 5 of the charging system 1 to the software application 4 via the navigation device 51 of the charging vehicle 5; displaying 120 at least the nearest mobile charging vehicle 5 on the mobile device 3 located in an electric vehicle 2 via the software application; and transmitting 130 a charging request for the electric vehicle 2 and at least one currentThe method comprises: transmitting the position P2 of the electric vehicle 2 to the displayed mobile charging vehicle 5 in the case of an electric battery 21 of the electric vehicle 2 requiring charging by the software application; transmitting 140 coordinates of a suitable common meeting point TP and a suitable meeting time TZ for charging the electric battery 21 of the electric vehicle 2 based on the received charging request to the mobile device 3 in the electric vehicle 2 requiring charging by the navigation device 51 of the charging vehicle 5; and converting 150 meeting point TP and meeting time TZ into navigation instructions for a driver of the electric vehicle 2 requiring charging by the software application 4 for navigating the electric vehicle 2 to the common meeting point TP. In one embodiment (dashed arrow), the method includes the additional step of at least periodically transmitting 170 the current position P5 of the charging vehicle 5 on a route to the common meeting point by theNavigation device 51 to the software application 4 for a query in the electric vehicle 2, and the display 180 of the current position P5 of the charging vehicle 5 on its way to the common meeting point TP by the software application 4 on a navigation display in the electric vehicle 2.
