Description

Technical Field

[0001] An aspect of the present invention relates to a method for connecting and disconnecting multiple electrical wires in a vehicle and an electrical road system. Background Technology

[0002] Instead of using the vehicle's own battery pack, internal combustion engine, or any other electrical energy source, such as one or more fuel cells, to provide power to the vehicle, for example, for propulsion, some vehicles can be connected to an Electrical Road System (ERS), which includes multiple wires, for example, for providing DC power to the vehicle. These multiple wires can include multiple overhead wires, multiple ground wires, or multiple lateral wires, or combinations thereof. When the vehicle is on the correct path on the road associated with the ERS, the vehicle can connect to and remain connected to the multiple wires according to certain processes, thereby saving fuel and / or its own electrical energy. Summary of the Invention

[0003] The inventors of this invention have discovered drawbacks in conventional solutions regarding the connection and / or disconnection of multiple wires between the vehicle and the electrical system (ERS). For example, some conventional solutions provide inefficient connection and disconnection processes for the multiple wires of the ERS, leading to inefficient use of the ERS and thus higher fuel and / or electricity consumption from the electrical energy (such as battery packs) carried by the vehicle.

[0004] The purpose of this invention is to provide a solution that alleviates or resolves the drawbacks and problems of conventional solutions.

[0005] The above and other objectives are achieved through the subject matter of the independent claims. Further advantageous embodiments of the invention can be found in the dependent claims.

[0006] According to a first aspect of the invention, the above-mentioned and other objects are achieved by a method for connecting and disconnecting multiple wires in a vehicle and an electrical road system, wherein the connecting and disconnecting process includes:

[0007] In response to a disconnect warning and if the vehicle is connected to multiple power lines (e.g., if the vehicle is connected relative to multiple power lines), the current from the multiple power lines to the vehicle's powertrain is interrupted.

[0008] This method includes:

[0009] While interrupting the current from multiple power lines to the vehicle's powertrain in response to a disconnection warning, the connection between the vehicle and the multiple power lines is maintained.

[0010] It should be understood that, according to the connection and disconnection process, the connection between the vehicle and the multiple wires of the electrical road system ERS is both mechanical and electrical, i.e., providing both mechanical and electrical connections between the vehicle and the multiple wires. It should also be understood that, according to the connection and disconnection process, the disconnection between the vehicle and the multiple wires of the electrical road system ERS is both mechanical and electrical, i.e., performing or implementing both electrical and mechanical disconnection between the vehicle and the multiple wires. Therefore, since the connection between the vehicle and the multiple wires (i.e., both mechanical and electrical connections) is maintained according to the method according to the first aspect and its embodiment, the current from the multiple wires to the vehicle itself is not interrupted. Conversely, according to the method according to the first aspect and its embodiment, the current from the multiple wires to the vehicle's power system is interrupted while maintaining the connection between the vehicle and the multiple wires.

[0011] It can be defined that the multiple power lines and / or electrical road system ERS are configured to provide power supply or electricity to vehicles connected to the multiple power lines. It can be defined that the multiple power lines and / or electrical road system ERS are configured to provide DC power to the connected vehicles. It can be defined that the multiple power lines and electrical road system ERS are configured for DC. It can be defined that the multiple power lines include or consist of two DC lines, one for DC+ and the other for DC-. The multiple power lines and electrical road system ERS can be configured for high voltages, such as above 60V, for example above 400V, or above 450V, for example above 650V. For example, the multiple power lines and electrical road system ERS can be configured for voltages up to 1500V and / or above 1500V.

[0012] The advantage of the method according to the first aspect is that, since the vehicle is maintained connected to the multiple wires, but current is blocked from the multiple wires to the vehicle's powertrain, the vehicle's powertrain can be reconnected to the electrical system ERS more quickly, for example, when the disconnection warning is cleared or disappears. Therefore, the advantage of the method according to the first aspect is that the step of reconnecting the vehicle to the electrical system ERS takes less time, which leads to more efficient use of the electrical system ERS, i.e., the vehicle remains connected to the electrical system ERS for a longer period and the electrical system ERS are used more by the vehicle, or in other words, the time the vehicle is disconnected from the electrical system ERS is reduced. This results in a reduction in fuel and / or electricity consumption of the electrical energy carried by the vehicle (such as the battery pack). Therefore, the efficiency of the electrical system ERS is improved. The advantage of the method according to the first aspect is that it improves the vehicle connection and disconnection process. The advantage of the method according to the first aspect is that it provides a more efficient connection and disconnection process for multiple wires, including, for example, a less time-consuming step of reconnecting the vehicle to the electrical system ERS. Because the amount of disconnection between the vehicle and the electrical road system ERS is reduced, and therefore the amount of reconnection is reduced, the wear and tear on the equipment used to connect and disconnect the vehicle is reduced. This results in less maintenance of the devices used to connect and disconnect the vehicle, which in turn leads to an increase in the vehicle's uptime—the time the vehicle is started, running, and actively used (e.g., driving on the road). The powertrain may include one or more electric motors or motors. It can be defined that the powertrain and / or one or more electric motors are configured to propel or drive the vehicle.

[0013] According to an advantageous embodiment of the method in the first aspect, the vehicle includes or is composed of electric vehicles or is an electric vehicle.

[0014] The connection and disconnection process involves connecting and disconnecting multiple wires between the electric vehicle and the electrical road system.

[0015] The connection and disconnection process includes:

[0016] In response to a disconnect warning and if the electric vehicle is connected to multiple power lines, the current from the multiple power lines to the electric vehicle's powertrain is blocked.

[0017] This method includes:

[0018] While interrupting the current from multiple power lines to the electric vehicle's powertrain in response to a disconnection warning, the connection between the electric vehicle and the multiple power lines is maintained.

[0019] An electric vehicle (EV) may, for example, include or consist of a hybrid electric vehicle (HEV) or a battery electric vehicle (BEV). Thus, a hybrid electric vehicle (HEV) and a battery electric vehicle (BEV) are versions or examples of an electric vehicle (EV). Alternatively, the vehicle or electric vehicle (EV) may be of the type described below in conjunction with the fifth aspect of the invention and / or in the detailed description.

[0020] According to other advantageous embodiments of the method according to the first aspect, the interruption of current from multiple wires to the vehicle's powertrain is performed within the vehicle. Since the multiple wires and the electrical system ERS can be configured to simultaneously supply power to two or more vehicles, the interruption of current from multiple wires to the vehicle's powertrain within the vehicle is advantageous. This embodiment has the advantage of improving the vehicle's connection and disconnection process. It provides a more efficient connection and disconnection process with respect to the multiple wires, including, for example, a less time-consuming step of reconnecting the vehicle to the electrical system ERS. An embodiment with a more specific location for interrupting the current from multiple wires to the vehicle's powertrain is disclosed below.

[0021] According to another advantageous embodiment of the method according to the first aspect, blocking the current from the multiple wires to the vehicle's powertrain includes reducing the current from the multiple wires to the vehicle's powertrain below a first threshold. This embodiment has the advantage of improving the vehicle's connection and disconnection process. It provides a more efficient connection and disconnection process with respect to the multiple wires, including, for example, a less time-consuming step of reconnecting the vehicle to the electrical road system (ERS). It can be defined that the reduction of the current from the multiple wires to the vehicle's powertrain below the first threshold is performed within the vehicle.

[0022] According to another advantageous embodiment of the method according to the first aspect, the current interruption from multiple wires to the vehicle's powertrain includes reducing the current from the multiple wires to the vehicle's powertrain to zero. The advantage of this embodiment is that it improves the vehicle's connection and disconnection process. The advantage of this embodiment is that it provides a more efficient connection and disconnection process with respect to multiple wires, including, for example, a less time-consuming step of reconnecting the vehicle to the electrical road system (ERS). It can be defined that the reduction of the current from the multiple wires to the vehicle's powertrain to zero is performed within the vehicle.

[0023] According to another advantageous embodiment of the method according to the first aspect, the method includes:

[0024] When the vehicle's connection to the multiple wires is maintained and the disconnection warning is cleared, current is transferred from the multiple wires to the vehicle's powertrain.

[0025] The advantage of this implementation is that the vehicle's powertrain can be reconnected to the ERS (Electrical Circuit System) more quickly when the disconnection warning is cleared or disappears. Therefore, this implementation results in less time spent reconnecting the vehicle to the ERS, leading to more efficient use of the ERS—the vehicle remains connected to the ERS for a longer period, and the ERS are used more frequently by the vehicle. This implementation improves the vehicle's connection and disconnection process.

[0026] According to an advantageous embodiment of the method according to the first aspect, the transmission of current from multiple wires to the vehicle's powertrain is performed in the vehicle. The advantage of this embodiment is that it improves the vehicle's connection and disconnection process. Specifically, it provides a more efficient connection and disconnection process for the multiple wires, including, for example, a less time-consuming step of reconnecting the vehicle to the electrical road system (ERS).

[0027] According to another advantageous embodiment of the method according to the first aspect, the transmission of current from the multiple wires to the vehicle's powertrain includes increasing the current from the multiple wires to the vehicle's powertrain to a level exceeding a second threshold. The advantage of this embodiment is that the vehicle's powertrain can be reconnected to the electrical system ERS more quickly when the disconnection warning is cleared or disappears. Therefore, the advantage of this embodiment is that the step of reconnecting the vehicle to the electrical system ERS takes less time, which leads to more efficient use of the electrical system ERS, i.e., the vehicle remains connected to the electrical system ERS for a longer period, and the electrical system ERS is used more frequently by the vehicle. The advantage of this embodiment is that it improves the vehicle's connection and disconnection process.

[0028] According to other advantageous embodiments of the method according to the first aspect, an increase in current is performed in the vehicle from multiple wires to the vehicle's powertrain.

[0029] According to another advantageous embodiment of the method according to the first aspect, the method includes:

[0030] When the vehicle is connected to multiple electrical wires and the disconnection warning is not cleared, the vehicle is disconnected from the multiple electrical wires while simultaneously cutting off the current from the multiple electrical wires to the vehicle's powertrain in response to the disconnection warning. The step of disconnecting the vehicle from the multiple electrical wires may be performed after the time period triggered by the issuance of the disconnection warning has expired, and if the disconnection warning has not been cleared within said time period.

[0031] According to another advantageous embodiment of the method according to the first aspect, the disconnect warning includes one or more of the following groups:

[0032] • The appropriate path for the vehicle to leave the road associated with the electrical road system;

[0033] • The voltage associated with the current in the powertrain system from multiple wires to the vehicle drops below the third threshold;

[0034] • The vehicle is about to leave the first predetermined area associated with the electrical road system; and

[0035] The vehicle is about to enter a second predetermined area associated with the electrical road system.

[0036] The advantage of this implementation scheme lies in its improved vehicle connection and disconnection process. Specifically, it provides a more efficient connection and disconnection process for multiple electrical lines, including fewer steps such as reconnecting the vehicle to the Electrical Road System (ERS). Additional disconnection warnings are also possible. The appropriate path can be defined and / or monitored by the Lane Keeping Assist / Assistance (LKA) system and / or Lane Departure Warning System (LDWS) and / or Global Positioning System (GPS). The first and / or second predetermined areas can be defined and / or monitored by GPS.

[0037] According to another advantageous embodiment of the method according to the first aspect, the vehicle includes an interface for providing a connection between the vehicle and multiple electrical wires, and

[0038] The interface includes a connecting device that can move between a connected position and a disconnected position, in which the connecting device and the vehicle are connected to multiple power lines, and in the disconnected position, the connecting device and the vehicle are disconnected from the multiple power lines.

[0039] The step of maintaining the connection between the vehicle and the multiple wires while cutting off the current from the multiple wires to the vehicle's powertrain in response to a disconnection warning includes keeping the connection device in the connected position.

[0040] By reducing the amount of disconnection between the vehicle and the electrical road system ERS, and thus the amount of reconnection, wear on the interface connection devices is reduced. This leads to less maintenance of the connection devices, which in turn increases the vehicle's uptime—the time spent starting, running, and actively using the vehicle (e.g., driving on the road). The advantage of this implementation is the improved vehicle connection and disconnection process. It provides a more efficient connection and disconnection process for multiple wires, including fewer steps such as reconnecting the vehicle to the electrical road system ERS. The connection devices may include, for example, mechanical linkages and / or foldable configurations, such as pantographs, or any other suitable configuration movable relative to the vehicle's chassis, such as telescopic configurations.

[0041] According to an advantageous embodiment of the method according to the first aspect, the step of disconnecting the vehicle from the multiple wires while blocking the current from the multiple wires to the vehicle's powertrain in response to a disconnection warning includes moving the connecting device from the connected position to the disconnected position.

[0043] The interface includes a DC-DC converter.

[0044] This method includes controlling a DC-DC converter to block and / or transmit current from multiple wires to the vehicle's powertrain.

[0045] The advantage of this implementation is that it provides effective interruption of current from multiple wires to the vehicle's powertrain without disconnecting the vehicle from the multiple wires. The advantage of this implementation is that it improves the vehicle's connection and disconnection process. The advantage of this implementation is that it provides a more efficient connection and disconnection process for multiple wires, including fewer steps such as reconnecting the vehicle to the Electrical Road System (ERS).

[0119] refer to Figure 5 and Figure 6 This schematically illustrates an aspect of an embodiment of a method 300 for connecting and disconnecting multiple wires 202 of a vehicle 100 and an electrical road system ERS200, according to the first aspect.

[0120] refer to Figure 5 The connection and disconnection process 400 includes:

[0121] • In response to or reacting to a disconnection warning and if vehicle 100 is connected to multiple wires 202 (e.g., if vehicle 100 is in a connected state relative to multiple wires 202, such as...) Figure 1 and Figure 2 (As shown), this blocks the current from multiple wires 202 to the power transmission system 104 of the vehicle 100.

[0122] The step of blocking the current from the multiple wires 202 to the powertrain 104 of the vehicle 100 may include interrupting the current from the multiple wires 202 to the powertrain 104 of the vehicle 100. In some embodiments, a disconnection warning is issued or occurs before the step of blocking the current from the multiple wires 202 to the powertrain 104 of the vehicle 100 (see [link to relevant documentation]). Figure 5 (Step 300a). In some embodiments, the connection and disconnection process 400 may include receiving or obtaining a disconnection warning. In some embodiments, blocking 401 current from multiple wires 202 to the powertrain 104 of vehicle 100 includes blocking current from multiple electrical contacts 122 to the powertrain 104 of vehicle 100.

[0123] refer to Figure 5 The method 300 includes:

[0124] • While blocking (e.g. interrupting) the current from the multiple wires 202 to the powertrain 104 of the vehicle 100 in response to a disconnection warning, 302 the connection between the vehicle 100 and the multiple wires 202 is maintained.

[0125] It should be understood that, according to the connection and disconnection process 400, the connection between vehicle 100 and the multiple wires 202 of the electrical road system ERS 200 is both mechanical (or physical) and electrical, i.e., providing both mechanical and electrical connections between vehicle 100 and the multiple wires 202. Therefore, since the connection between vehicle 100 and the multiple wires 202 (i.e., both mechanical and electrical connections) is maintained according to the embodiment of the method 300 of the first aspect, the current from the multiple wires 202 to vehicle 100 itself is not interrupted. Conversely, according to the embodiment of the method 300 of the first aspect, the current from the multiple wires 202 to the powertrain 104 of vehicle 100 is interrupted 401 while maintaining the connection between vehicle 100 and the multiple wires 202 (i.e., both mechanical and electrical connections).

[0126] It can be defined that the current blocking 401 from the multiple wires 202 to the powertrain 104 of the vehicle 100 is performed within the vehicle 100. It can be defined that the current blocking 401 from the multiple wires 202 to the powertrain 104 of the vehicle 100 is performed within the vehicle 100 or within the interface 110 but outside the multiple electrical contacts 122. It can be defined that the current blocking 401 from the multiple wires 202 to the powertrain 104 of the vehicle 100 is performed within the vehicle 100 but outside the multiple electrical contacts 122 and outside the connection device 112. For example, the current blocking 401 from the multiple wires 202 to the powertrain 104 of the vehicle 100 can be performed in the tower 132 of the interface 110 or elsewhere in the vehicle 100 but outside the multiple electrical contacts 122 and / or outside the connection device 112.

[0127] In some implementations, when vehicle 100 includes an interface 110 for providing a connection between vehicle 100 and multiple wires 202, and when interface 110 includes multiple electrical contacts 122, the blocking step 401 may be defined as blocking current from the multiple electrical contacts 122 to the powertrain 104 of vehicle 100, so as to block current from the multiple wires 202 to the powertrain 104 of vehicle 100.

[0128] refer to Figure 1 and 2 Disconnect warnings can include one or more of the following groups:

[0129] • Vehicle 100 is about to leave the correct path 206 of road 208 associated with the electrical road system ERS 200;

[0130] • The voltage associated with the current from the multiple wires 202 to the powertrain 104 of the vehicle 100 drops below the third threshold.

[0131] Vehicle 100 will leave or exit the first predetermined area 210 associated with the electrical road system ERS 200; and

[0132] Vehicle 100 is about to enter the second predetermined area 212 associated with the electrical road system ERS 200.

[0133] exist Figure 2 and Figure 3The appropriate path 206, schematically illustrated, can be a path 206 along an extension of the plurality of wires 202, along which the vehicle 100 can be appropriately (e.g., safely) maintained connected to the plurality of wires 202, for example by means of the interface 110 disclosed above. Furthermore, the correct path 206 can be a path 206 along an extension of the plurality of wires 202, along which the vehicle 100 can be correctly (e.g., safely) connected (e.g., performing one or more steps for connection) to the plurality of wires 202, for example by means of the interface 110 disclosed above. The appropriate path 206 can be defined and / or monitored by a lane keeping assist / assistance system (LKA) and / or a lane departure warning system (LDWS) and / or a global positioning system (GPS).

[0134] The meaning of vehicle 100 leaving the correct path 206 or the first predetermined area 210 can correspond to vehicle 100 leaving the correct path 206 or the first predetermined area 210 soon or within a short period of time. In other words, it is about to leave the correct path 206 or the first predetermined area 210. The meaning of vehicle 100 entering the second predetermined area 212 can correspond to vehicle 100 entering the second predetermined area 212 soon or within a short period of time. In other words, it is about to enter the second predetermined area 212.

[0135] See Figure 1 The first predetermined area 210 can be an area where vehicle 100 is registered as a user, for example, via a subscription and is permitted to use the Electric Road System ERS 200. The second predetermined area 212 can be an area where vehicle 100 is not registered as a user, for example, without a subscription, and therefore is not permitted to use the Electric Road System ERS. The first predetermined area 210 and / or the second predetermined area 212 can be defined and / or monitored by a Global Positioning System (GPS), or a cellular communication network, or a combination thereof, or any other system.

[0136] refer to Figure 2 and Figure 5 When vehicle 100 includes an interface 110 providing a connection between vehicle 100 and multiple wires 202, and when interface 110 includes a connection device 112, for example, according to any of the embodiments disclosed above, the step of maintaining the connection between vehicle 100 and multiple wires 202 while blocking 401 current from multiple wires 202 to the powertrain 104 of vehicle 100 in response to a disconnection warning may include maintaining 302a the connection device 112 in a connected position (e.g., as shown in the diagram). Figure 1 and Figure 2 (As shown).

[0137] refer to Figure 5In some embodiments of the method 300 according to the first aspect, blocking 401 of the current from the multiple wires 202 to the powertrain 104 of the vehicle 100 may include reducing the current from the multiple wires 202 to the powertrain 104 of the vehicle 100 to below a first threshold.

[0138] refer to Figure 5 In some embodiments of the method 300 according to the first aspect, blocking 401 of the current from the multiple wires 202 to the powertrain 104 of the vehicle 100 may include reducing 401b of the current from the multiple wires 202 to the powertrain 104 of the vehicle 100 to zero.

[0139] refer to Figure 4 and Figure 5 When vehicle 100 includes an interface 110 for providing a connection between vehicle 100 and multiple wires 202, and when interface 110 includes a DC-DC converter 126, embodiments of the method 300 according to the first aspect may include controlling 301a the DC-DC converter 126 to block 401 current from the multiple wires 202 to the powertrain 104 of vehicle 100. Some embodiments may include controlling the DC-DC converter 126 to block current from multiple electrical contacts 122 to the powertrain 104 of vehicle 100 in order to block 401 current from the multiple wires 202 to the powertrain 104 of vehicle 100.

[0140] refer to Figure 4 and Figure 5 When vehicle 100 includes an interface 110 for providing a connection between vehicle 100 and multiple wires 202, and when interface 110 includes an electrically operable switch 128 switchable between an open and closed position, embodiments of the method 300 according to the first aspect may include switching switch 128 301b to an open position to block current 401 from the multiple wires 202 to the powertrain 104 of vehicle 100. Some embodiments may include switching switch 128 to an open position to block current from multiple electrical contacts 122 to the powertrain 104 of vehicle 100, thereby blocking current 401 from the multiple wires 202 to the powertrain 104 of vehicle 100.

[0141] refer to Figure 5In some implementations, for example for safety reasons, the steps of controlling the 301a DC-DC converter 126 and switching the 301b switch device 128 to block the current from the multiple wires 202 to the powertrain 104 can be combined. When combining the steps of controlling the 301a DC-DC converter 126 and switching the 301b switch device 128, it may be advantageous to first control the 301a DC-DC converter 126 to block the current from the multiple wires 202 to the powertrain 104 of the vehicle 100, and then switch the 301b switch device 128 to the off position, because this process or strategy can reduce wear on the switch device 128 (e.g., wear from arcing or welding), since the switch device 128 is switched to the off position when the circuit has already been disconnected or interrupted by the DC-DC converter 126.

[0142] refer to Figure 2 and 5 The figure, according to some implementations of the method 300 of the first aspect, may include:

[0143] • When the connection between the vehicle 100 and the multiple wires 202 is maintained 302 and the disconnection warning is cleared (e.g., cleared for a period of time), current is transferred from the multiple wires 202 304 to the powertrain 104 of the vehicle 100.

[0144] The phrase “disconnect warning cleared” can be alternatively expressed as “disconnect warning withdrawn”, “disconnect warning disabled”, or “disconnect warning disappeared”.

[0145] It can be defined that the transmission 304 of current from the multiple wires 202 to the powertrain 104 of the vehicle 100 is performed within the vehicle 100. It can also be defined that the transmission 304 of current from the multiple wires 202 to the powertrain 104 of the vehicle 100 is performed within the vehicle 100 but outside the multiple electrical contacts 122. Furthermore, it can be defined that the transmission 304 of current from the multiple wires 202 to the powertrain 104 of the vehicle 100 is performed within the vehicle 100 but outside the multiple electrical contacts 122 and / or outside the connecting device 112. For example, the transmission 304 of current from the multiple antennas 202 to the powertrain 104 of the vehicle 100 can be performed in the tower 132 of the interface 110 or elsewhere in the vehicle 100 but outside the multiple electrical contacts 122 and / or outside the connecting device 112.

[0146] In some implementations, when vehicle 100 includes an interface 110 for providing a connection between vehicle 100 and multiple wires 202, and when interface 110 includes multiple electrical contacts 122, it can be defined that the transmission 304 of current from the multiple wires 202 to the powertrain 104 of vehicle 100 includes transmitting current from the multiple electrical contacts 122 to the powertrain 104 of vehicle 100, so as to transmit current from the multiple wires 202 304 to the powertrain 104 of vehicle 100.

[0147] refer to Figure 5 In some embodiments of the method 300 according to the first aspect, the transfer 304 of current from the plurality of wires 202 to the powertrain 104 of the vehicle 100 may include increasing the current from the plurality of wires 202 to the powertrain 104 of the vehicle 100 by 304a to above a second threshold. It may be defined that, within the vehicle 100, for example at any location mentioned above for the transfer 304 of current from the plurality of wires 202 to the powertrain 104, the increase 304a of current from the plurality of wires 202 to the powertrain 104 of the vehicle 100 is performed.

[0148] refer to Figure 4 and Figure 5 When vehicle 100 includes an interface 110 for providing a connection between vehicle 100 and multiple wires 202, and when interface 110 includes a DC-DC converter 126, embodiments of the method 300 according to the first aspect may include controlling 303a the DC-DC converter 126 to deliver current 304 from the multiple wires 202 to the powertrain 104 of vehicle 100. Some embodiments may include controlling the DC-DC converter 126 to deliver current from multiple electrical contacts 122 to the powertrain 104 of vehicle 100, so as to deliver current 304 from the multiple wires 202 to the powertrain 104 of vehicle 100.

[0149] refer to Figure 4 and Figure 5 When vehicle 100 includes an interface 110 for providing a connection between vehicle 100 and multiple wires 202, and when interface 110 includes an electrically operable switch 128 switchable between an open and closed position, embodiments of the method 300 according to the first aspect may include switching switch 128 303b to a closed position to transfer current from multiple wires 202 304 to the powertrain 104 of vehicle 100. Some embodiments may include switching switch 128 to transfer current from multiple electrical contacts 122 to the powertrain 104 of vehicle 100 to transfer current from multiple wires 202 304 to the powertrain 104 of vehicle 100.

[0150] refer to Figure 5 In some embodiments, the steps of controlling the 303a DC-DC converter 126 to deliver the 304 current and switching the 303b switching device 128 to deliver the 304 current can be combined, for example, when both the DC-DC converter 126 and the switching device 128 block the 401 current in the preceding steps for safety reasons. When combining the steps of controlling the 303a DC-DC converter 126 and switching the 303b switching device 128 to deliver the 304 current, it may be advantageous to first switch the switching device 128 to the closed position and then control the 303a DC-DC converter 126 to deliver the current from the multiple wires 202 to the powertrain 104 of the electric vehicle 100.

[0151] refer to Figure 5 Some implementations of method 300 according to the first aspect may include:

[0152] • When the connection between vehicle 100 and multiple wires 202 is maintained 302 and the disconnection warning is not cleared (e.g., not cleared for a period of time), vehicle 100 is disconnected from multiple wires 202 305 while the current from multiple wires 202 to the powertrain 104 of vehicle 100 is interrupted 401 in response to the disconnection warning.

[0154] It is important to disconnect vehicle 100 from multiple power lines 202 305 if the disconnection warning is not cleared. For example, if vehicle 100 leaves the correct path 206 of road 208 associated with the electrical road system ERS 200 without disconnecting vehicle 100 305, for example, by not removing the connection device 112 from the connection position (e.g., as...). Figure 1 and Figure 2 (As shown) Move 305a to the disconnect position (e.g., as shown) Figure 3As shown), both the multiple wires 202 and the connecting device 112 may be damaged. For example, the connecting device 112 may come into contact with at least one of the multiple wires 202 from the side or laterally, or it may be sandwiched between the multiple overhead wires 202 and the multiple lateral wires. Regarding the multiple ground wires, if the connecting device remains in the connected position for too long, the connecting device may be damaged by the road 208 or by any object on the road 208. Therefore, if the vehicle 100 leaves the correct path 206 of the road 208, it is recommended to quickly move the connecting device to the disconnected and / or retracted position.
