[0002] As more and more vehicles adopt electric drive, electrification becomes increasingly important. With the increase in the number of electric vehicles, the need for efficient charging of vehicle batteries also increases. Furthermore, vehicle batteries have larger capacities, requiring more energy to charge in order to avoid long charging times. However, if electric vehicle batteries must be charged with higher energy, the battery temperature rises during charging. The battery can reach temperature levels that require cooling. In some use cases, charging uses up to or exceeds 1000kW of electrical energy. This high-power charging generates heat, causing temperature increases. The temperature rise during high-power charging can be even higher, depending on the ambient temperature. Therefore, ambient temperature can also affect the temperature of the vehicle battery being charged by a charging station.

Attached Figure Description

[0025] In the following, feasible embodiments of various aspects of the invention will be described in more detail with reference to the accompanying drawings.

[0026] Figure 1A block diagram illustrating a feasible exemplary embodiment of a charging station according to a first aspect of the present invention is shown.

[0027] Figure 2 A flowchart is shown illustrating the steps to be performed when using a charging station according to the present invention to load a vehicle battery. Detailed Implementation

[0028] from Figure 1 As can be seen from the block diagram, the charging station 1 according to the first aspect of the present invention can be used to charge at least one vehicle battery 2A of an electric vehicle 2 connected to the charging station 1. The charging station 1 can be used to simultaneously charge the vehicle batteries 2A of multiple electric vehicles 2 connected to the charging station 1. The charging station 1 can be used to charge the vehicle batteries 2A of different types of electric vehicles 2, including electric cars or trucks, but can also be used for smaller devices such as electric bicycles. Figure 1 In the illustrated embodiment, the electric vehicle 2 can be connected to the charging station 1 via a pluggable charging connector 3 inserted into a corresponding socket 7 in the vehicle 2. The charging connector 3 is adapted to transfer electrical energy from the charging station 1 to the vehicle battery 2A of the vehicle 2 during charging. A valve in the charging station 1 and / or a valve in the vehicle 2 opens before, during, and / or after the charging process to supply a medium M of appropriate temperature into the battery conditioning unit 2B of the vehicle 2 to optimize the temperature of the vehicle battery 2A for the corresponding charging process. The supplied medium M may include a fluid with high heat capacity.

[0029] The battery conditioning unit 2B of vehicle 2 receives medium M from charging station 1 through at least one open valve and is adapted to optimize the temperature of vehicle battery 2A before, during, and / or after the charging process. Vehicle battery 2A. In a preferred embodiment, charging station 1 has at least one such... Figure 1 The portable charging station shown is equipped with an integrated battery pack 1A. The integrated battery pack 1A is adapted to store electrical energy, which can be transferred at least partially during the charging process via power lines 9 within cable 4 and a pluggable charging connector 3 to the vehicle battery 2A of an electric vehicle 2 connected to the portable charging station 1 via cable 4. Figure 1 In the illustrated embodiment, charging station 1 is a mobile charging station not connected to the public power grid. Charging station 1 can be integrated into a housing that can be lifted by a crane from a transport truck. The crane of the transport truck can lift the housing of charging station 1 onto the truck's transport platform, which transports charging station 1 to a central recharging facility adapted to recharge at least one battery pack 1A of charging station 1 that has been depleted while performing a charging process for charging vehicle battery 2A. After the central recharging facility recharges battery pack 1A, mobile charging station 1 can be transported back to the desired location by a transport truck and deployed on-site by lifting the housing of charging station 1 to the ground using a crane. Therefore, Figure 1The mobile charging station 1 shown can be easily relocated to other locations to provide the local possibility of recharging the vehicle battery 2A.

[0030] Charging station 1 includes a medium temperature regulating unit 1B, which regulates the temperature of medium M, such as a fluid, to an appropriate temperature before supplying medium M through at least one open valve of charging station 1 and / or vehicle 2. The medium temperature of medium M can be regulated by medium temperature regulating unit 1B according to the battery temperature of vehicle battery 2A of vehicle 2. This regulation can also occur before vehicle battery 2A of vehicle 2 is connected to charging station 1 via cable 4, for example, for vehicle 2 approaching charging station 1. In this case, the current battery temperature of vehicle battery 2A can be notified to charging controller 1C of charging station 1, for example, via a wireless communication link. Charging controller 1C can control medium temperature regulating unit 1B to pre-adapt the temperature of medium M before vehicle 2 arrives at charging station 1, so that medium M with an appropriate temperature is available when vehicle 2 is connected to charging station 1 via cable 4. This reduces the time required to recharge vehicle battery 2A. In an alternative embodiment, medium temperature regulating unit 1B regulates the temperature of medium M after vehicle 2 has been connected to charging station 1. In a feasible embodiment, the battery temperature of vehicle battery 2A is regulated by means of, Figure 1 The temperature is determined by the vehicle 2 temperature determination unit 2C, as shown in the block diagram. The determined battery temperature can be notified by the vehicle 2 temperature determination unit 2C to the charging controller 1C of the charging station 1. The charging controller 1C of the charging station 1 uses the received information about the battery temperature to control the charging station 1's dielectric temperature regulation unit 1B. For example... Figure 1 As shown, the charging controller 1C and the dielectric temperature regulation unit 1B can be interconnected via an integrated control and data bus. The temperature determination unit 2C may include at least one temperature sensor adapted to measure the current temperature of the vehicle battery 2A and notify the integrated battery management unit 2D of the vehicle 2 of the temperature of the vehicle battery 2A, such as... Figure 1As shown. The temperature determination unit 2C and the battery management unit 2D can also be connected via an integrated control and data bus that allows communication. The battery regulation unit 2B is connected to the battery management unit 2D of the vehicle 2 via the control and data bus. The temperature measured by the sensor of the temperature determination unit 2C is notified to the battery management unit 2D of the vehicle 2, which can be transmitted to the charging controller 1C via a wireless communication link and / or via a communication line extending through the charging cable 4. The temperature data can also be provided to the charging controller 1C via a wireless network, such as a mobile phone network, which is used to forward the temperature data from the battery management unit 2D to a transceiver integrated in the charging station 1, which supplies the received information. Therefore, a wireless communication link can exist between the battery management unit 2D and the charging controller 1C, which is adapted to provide bidirectional communication for exchanging data and / or information.

[0031] exist Figure 1 In the illustrated embodiment, the medium temperature regulating unit 1B of the charging station 1 is connected to the battery regulating unit 2B of the vehicle 2 via a medium feed line 5. The medium feed line 5 is configured to feed medium M with a suitable temperature T into the battery regulating unit 2B. A medium feedback line 6 is also provided to feed medium back to the medium temperature regulating unit 1B of the charging station 1. Therefore, in the illustrated embodiment, if the controllable valve is opened, the medium temperature regulating unit 1B and the battery regulating unit 2B form a closed loop, and the medium M can circulate within this closed loop.

[0032] exist Figure 1 In the illustrated embodiment, cable 4 includes a power supply line 9 through which electrical energy can be transferred from battery pack 1A to vehicle battery 2A connected to charging station 1. Cable 4 also includes a feed line 5 and a return line 6 for circulating the medium M. Figure 1 In the illustrated embodiment, controllable valve 8A is located in feed line 5, and another controllable valve 8B is located in feedback line 6. Both controllable valves 8A and 8B can be controlled by the charging controller 1C of charging station 1. If valves 8A and 8B are open, the medium M can be supplied to the battery conditioning unit 2B of vehicle 2 at an appropriate temperature T to optimize the temperature of vehicle battery 2A for the charging process. Different valves 8A and 8B can be opened and closed simultaneously (i.e., in parallel) or in a predetermined sequence. For example, before closing valve 8A after a predetermined waiting time, the first valve 8A can be opened and the medium pumped to the battery conditioning unit 2B of vehicle 2. After valve 8A has been closed, the other valve 8B can be opened to pump the medium back to the medium conditioning unit 1B of charging station 1. This serial process can be executed at high speed. Charging station 1 may include an integrated pump that provides sufficient pressure to transfer the medium M from medium temperature conditioning unit 1B via feed line 5 to battery conditioning unit 2B and back via feedback line 6.

[0033] exist Figure 1 In the illustrated embodiment, controllable valves 8A and 8B are integrated into the charging station 1. In an alternative embodiment, at least one controllable valve may be integrated into the pluggable charging connector 3 to open and close in response to a valve control signal CRTL received from the charging controller 1C of the charging station 1 via a control signal line. In yet another feasible alternative embodiment, at least one controllable valve may also be integrated into the socket 7 of the vehicle 2. In yet another feasible implementation, the medium M supplied by the medium temperature regulating unit 1B of the charging station 1 can also be used to heat and / or cool the passenger compartment of the vehicle 2 during charging.

[0034] In one feasible embodiment, the insertion of the pluggable charging connector 3 of charging station 1 into the corresponding socket 7 of vehicle 2 can be detected by the insertion detection unit of vehicle 2 and / or by the insertion detection unit of charging station 1. The detected insertion can be notified to the charging controller 1C of charging station 1 and / or the battery management unit 2D of vehicle 2. In one feasible embodiment, if the insertion of the pluggable charging connector 3 into the socket 7 of vehicle 2 has been detected by the insertion detection unit of charging station 1 and / or the insertion detection unit of vehicle 2, then at least one controllable valve, such as... Figure 1 The controllable valves 8A and 8B shown in the diagram open automatically.

[0035] In a preferred embodiment, the battery conditioning unit 2B of vehicle 2 includes a heat exchange device adapted to exchange heat between the medium M supplied by charging station 1 and the battery cooling circuit of vehicle 2. In this embodiment, vehicle 2 includes two independent cooling circuits connected by a heat exchange device integrated into the chassis of vehicle 2. In an alternative embodiment, the connected electric vehicle 2 includes only one cooling circuit, to which the medium temperature conditioning unit 1B is connected via feed line 5 and feedback line 6. In this embodiment, vehicle battery 2A can be cooled during charging, and vehicle 2 does not require a separate cooling device.

[0036] In one feasible embodiment of charging station 1, charging station 1 includes a first communication interface that allows communication between the charging controller 1C of charging station 1 and the battery management unit 2D of vehicle 2 via a pluggable charging connector 3 of charging station 1. In another feasible embodiment of charging station 1, charging station 1 includes a second communication interface for providing communication between the charging controller 1C of charging station 1 and the battery management unit 2D of vehicle 2. The second communication interface may include a wireless communication interface that allows communication between the charging controller 1C and the battery management unit 2D of a remote vehicle near charging station 1 for the intended charging process of its vehicle battery 2A. The charging power provided by charging station 1 can vary depending on usage. In one feasible embodiment, vehicle battery 2A of vehicle 2 is charged at a power greater than 100kW via the power line 9 of charging cable 4 during the charging process.

[0037] Figure 2 The operation of a charging station 1 according to the present invention is illustrated. In the exemplary process shown, in step S0, the driver or user of the electric vehicle intends to recharge the vehicle battery 2A of its vehicle 2 and initiates the process.

[0038] In one feasible implementation, charging station 1 can be displayed to the user of vehicle 2 by the navigation system of vehicle 2. In step S1, the driver or user of vehicle 2 can make a reservation at charging station 1 for a future scheduled charging process. The reservation message is transmitted from the battery management unit 2D of vehicle 2 to the charging controller 1C of charging station 1 via a wireless communication link. The reservation message can reserve a time slot for the scheduled charging process for the corresponding vehicle 2. In one feasible embodiment, the reservation message may include additional information about the vehicle battery 2A, namely its battery capacity. In addition, the current battery temperature measured by temperature determination unit 2C can be sent to charging controller 1C. Other information, such as an indication of the required medium temperature for the expected charging process, may also be transmitted. The charging controller 1C of charging station 1 can process the received message and reserve a corresponding time slot TS for the upcoming future charging process of vehicle 2. The required time period can be calculated based on the received information, and the time slot TS can be reserved by controller 1C. In one possible implementation, the charging controller 1C may control the medium temperature regulating unit 1B to heat or cool the medium M to an appropriate temperature based on information and / or other parameters received from the battery management unit 2D, such as the chemical composition of the medium M and / or the current ambient temperature. In another possible implementation, the medium temperature regulating unit 1B may include a container or tank filled with a predetermined volume of the medium M, which may be heated and / or cooled in response to a control signal from the charging controller 1C, such that an appropriate medium temperature can be achieved even before the vehicle 2 arrives at the charging station 1.

[0039] In step S2, the vehicle 2 is driven to the charging station 1, and the user can open the charging cover.

[0040] In another step S3, for example, if the insertion detection unit has detected that the pluggable connector 3 is inserted into the socket 7 of vehicle 2, charging station 1 can be activated. Once charging station 1 is activated, further processes can be triggered, such as authentication of the user of vehicle 2 and / or vehicle 2 itself. Furthermore, a payment procedure can be initiated in response to the insertion detected in step S3. In an alternative embodiment, activation of charging station 1 can be performed before vehicle 2 arrives at the location of charging station 1. The navigation system of vehicle 2 can determine the instantaneous position of the moving vehicle 2 and, for example, signal that vehicle 2 is about to arrive at charging controller 1C if vehicle 2 is within a predetermined range of charging station 1.

[0041] In another step S4, an electrical connection is established between the battery pack 1A of the charging station 1 and the vehicle battery 2A via the power line 9 integrated in the cable 4.

[0042] In another step S5, communication between the battery management unit 2D and the charging controller 1C can be performed via a first and / or second communication interface or via power line communication with the PLC along the power signal line 9. For example, the controller 1C can identify the type of vehicle 2, specifically whether it includes a separate battery cooling circuit.

[0043] In another step S6, the controller 1C can activate a pumping device adapted to pump the medium M from the medium temperature regulating unit 1B to the battery regulating unit 2B of the vehicle 2 via the feed line 5, and back to the medium temperature regulating unit 1B via the feedback line 6. In a feasible embodiment, the pumping rate can be adjusted according to the rate of electrical power used during charging.

[0044] In step S7, the medium M begins to flow from the charging station 1 via the feed line 5 of the cable 4 to the battery conditioning unit 2B of the vehicle 2. For this purpose, an internal valve integrated in the charging station 1 can be opened in step S7. The battery conditioning unit 2B may include a heat exchange device adapted to perform heat exchange between the received medium M and the separate battery cooling circuit of the vehicle 2.

[0045] When the fluid pump starts, the charging controller 1C can also control the opening of other controllable valves in the medium transfer circuit in step S8, specifically socket 7 in connector 3 or integrated in vehicle 2. The number of controllable valves may vary depending on the use case. Furthermore, valves may be as follows: Figure 1The device is located in charging station 1, or in an alternative embodiment, in vehicle 2. In a feasible embodiment, at least one controllable valve is located in the pluggable charging connector 3 and / or socket 7. The valve can be controlled by charging controller 1C, for example, via power line communication of power line 9 of cable 4, such that a control signal is transmitted via power line 9 to the controllable valve integrated in the pluggable connector 3 of cable 4.

[0046] Simultaneously, in step S9, electrical energy can begin to flow from battery pack 1A to vehicle battery 2A via power line 9. In a feasible embodiment, in step S9, charging controller 1C can control an electromechanical or electronic switch to connect battery pack 1A to vehicle battery 2A. Depending on the location of the electronic switch or electromechanical relay, in a feasible embodiment, the control signal can also be transmitted via power line communication PLC using power line 9. Since the medium M flows parallel to power line 9 through the cable, it also cools power line 9 during charging.

[0047] Therefore, in a feasible embodiment, in step S10, the current I for charging the vehicle battery 2A and the medium M having a suitable temperature T are transmitted in parallel via cable 4. The temperature of the medium M flowing through the feed line 5 and the medium M returned via the feedback line 6 can be continuously measured and notified to the charging controller 1C and / or the battery management unit 2D of the vehicle 2. Additional temperature sensors may be provided in the pluggable connector 3, the socket 7, and / or along the cable 4.

[0048] In another step S11, the charging process is stopped. After the charging process is stopped, the flow of the medium M may be maintained for a predetermined period of time to provide the cooling and / or heating required by the vehicle battery 2A.

[0049] In another step S12, in response to a control signal provided by the charging controller 1C of the charging station 1, the medium flow is stopped by closing at least one controllable valve. After the medium flow is interrupted in step S12, the user of the vehicle 2 can disconnect the charging connector 3 from the socket 7 of the vehicle 2 in step S13. This triggers the closure of the internal valve integrated in the housing of the charging station 1.

[0050] By providing a medium M at an appropriate temperature, the charging process of the vehicle battery 2A can be optimized, thus improving charging performance. An appropriate temperature allows for faster loading of the vehicle battery 2A and also increases the battery's operational life. The supply of medium M at an appropriate temperature also improves process safety by avoiding the unacceptable temperature range of the vehicle battery 2A. Therefore, the charging process can be performed faster and more reliably. The temperature of the medium, regulated by the medium temperature regulation unit 1B, can be adjusted according to the capacity of the vehicle battery 2A and the amount of electrical energy to be transferred to it. Furthermore, the temperature of the supplied medium M can be adjusted according to the desired charging rate and / or the available charging time.

[0051] In one feasible embodiment, the charging controller 1C can be connected via a communication link to a remote central server that provides cloud services to the charging station 1.

[0052] Depending on the application, different types of media M can be used, such as different types of fluids and / or gases. Furthermore, different types of controllable valves can be used depending on the application or use case.

[0053] The fast charging method according to the present invention can be executed in the background, so that the client or user may not even be aware of the fast charging method. In an alternative embodiment, the user is notified of the fast charging. Furthermore, the charging time saved through temperature regulation can be calculated by the processor of the charging controller 1C and notified to the user.
