    [001] [001] The present invention relates to a retractable charging station for charging a vehicle's battery. BRIEF DESCRIPTION OF THE STATE OF THE TECHNIQUE
    [002] [002] Electric vehicles include vehicles entirely powered by electricity, the driving force of which is provided solely by electricity, and hybrid vehicles, whose driving force is provided by a combination of electricity and another source, such as an internal combustion engine. Electric vehicles are becoming increasingly popular. Most electric vehicles depend on their power reserve (for example, a battery) being charged from a charging station when the vehicle is stopped. Charging stations can be provided in service areas and car owners' garages. This may be sufficient in regions of the world where it is normal to park in a garage. However, in some areas, it is normal to park on the street.
    [003] [003] Vehicle-to-grid (V2G) systems, in which electric vehicles communicate with the grid to return electricity to the grid or reduce its charging rate, provide a mechanism flexible to meet grid power requirements at peak times, as well as allowing the vehicle owner to recharge the vehicle during off-peak hours at cheaper prices. Improper use / control and damage to charging stations can adversely affect the vehicle owner and the grid operators.
    [004] [004] If the owner of an electric vehicle parks on the street in front of His house, it would be possible for him to run an electric cable from the house to the vehicle to charge the vehicle. However, this cable can cross a sidewalk between the house and the street, which would pose a danger to passersby.
    [005] [005] An improved mechanism is required for loading vehicles on the street. SUMMARY OF THE INVENTION
    [006] [006] In accordance with the present invention, a charging station is provided to charge a vehicle battery, comprising a base portion configured for mounting on a substructure, a charging portion with a charging outlet for connection to a vehicle and a retraction mechanism for moving the loading portion between an extended position in which it extends out of the base portion and a retracted position and a controller for controlling the retraction mechanism, the controller being configured to determine whether a period of predetermined time has elapsed since the most recent charging of the charging outlet has ceased and causes the retract mechanism to move from the charging part to the retracted position, if it is determined that the predetermined period of time has elapsed since the most recent electrical supply to the outlet .
    [007] [007] The controller can also be configured to adjust the predetermined time period, depending on the previous behavior of at least one user.
    [008] [008] The charging station may further comprise a user interface configured to receive input from a user and the controller is further configured to adjust the predetermined period of time depending on the input received.
    [009] [009] The charging station may further comprise a receiving apparatus for receiving wireless signals and the controller is further configured to adjust the predetermined period of time depending on the received wireless signals.
    [010] [010] The receiving device can be configured to receive wireless signals via at least one via Bluetooth (RTM), Wi-Fi, NFC (near field communication) or RFID.
    [011] [011] The controller can also be configured to adjust the predetermined period of time, depending on a measure of user proximity derived from the received wireless signal.
    [012] [012] The controller can also be configured to determine the load of a connected vehicle.
    [013] [013] The controller can also be configured to adjust the predetermined time period, depending on the most recently determined load of a connected vehicle.
    [014] [014] The controller can also be configured to adjust the predetermined time period, depending on the time of day.
    [015] [015] The controller can also be configured to adjust the predetermined time period, depending on the signals received from nearby charging stations.
    [016] [016] The controller can also be configured to adjust the predetermined time period, depending on the weather.
    [017] [017] The controller can also be configured to determine if the movement of the loading part or retraction mechanism is obstructed and to prevent movement if an obstruction is detected.
    [018] [018] The charging part can be connected to the charging socket using a charging cable. The controller can further be configured to cause the loading part to be wrapped around the loading cable before causing the retract mechanism to move the loading part to the stowed position.
    [019] [019] The loading part may comprise a telescopic column.
    [020] [020] The charging socket may comprise at least one of an electrical outlet and a wireless electrical charging device.
    [021] [021] The charging station may further comprise a data entry cable, and the controller may extend or retract the charging portion depending on the data received via the data entry cable.
    [022] [022] The charging part can be configured to charge the battery of an electric road vehicle.
    [023] [023] The retraction mechanism can be configured to move the substantially vertical loading part between an extended position and a retracted position.
    [024] [024] The base part can be configured for mounting on a substructure that comprises a road or passage.
    [025] [025] The controller can also be configured to detect an oscillation in the energy supplied to the charging station. The controller can also be configured to stop charging when a power surge is detected. The controller can also be configured to cause the retraction mechanism to retract the loading part when a power surge is detected.
    [026] [026] The controller can determine that charging has stopped by determining that a vehicle has been electrically disconnected.
    [027] [027] The controller can determine that charging has stopped by determining that the battery of a connected vehicle is fully charged.
    [028] [028] The base part can also comprise an anchoring portion to fix the base part to the substructure.
    [029] [029] The distal end of the loading part can be substantially flush with one face of the base part when the loading part is retracted.
    [030] [030] The distal end of the loading part can be substantially flush with a surface of the substructure when the loading part is retracted.
    [031] [031] One face of the base part may be substantially flush with a substructure surface when the load portion is retracted.
    [032] [032] The base and loading parts can form a seal to resist the entry of fluids into the base part when the loading part is retracted. BRIEF DESCRIPTION OF THE DRAWINGS

    [039] [039] The following description is presented to allow anyone skilled in the art to make and use the invention, and is provided in the context of a specific application. Several changes in the disclosed modalities will be readily clear to those skilled in the art.
    [040] [040] The general principles defined here can be applied to other modalities and applications without departing from the spirit and scope of the present invention. Therefore, the present invention is not intended to be limited to the modalities shown, but must be in accordance with the broader scope consistent with the principles and characteristics disclosed herein.
    [041] [041] Figure 1 is a schematic diagram of a charging station 100. The charging station comprises a charging part 101 with a charging socket 104 for connection to a vehicle 300. The charging part is a column, pillar or another structure that can carry the charging socket. The charging socket can be any structure suitable for transferring electrical charge to a vehicle, for example, one or more electrical outlets, plugs or wireless charging systems. The charging socket can be located directly on the charging part or can be connected to the charging part by an electric cable. If a charging cable is used, the charging portion may contain a receptacle or for storing the retracted charging cable or a station to which the charging socket can be attached when not in use. The charging part may comprise a drive mechanism for mechanically removing the charging cable when not in use. The drive mechanism can pull the charging cable into the receptacle, or so that a charging socket on the distal end of the cable is flush with the outside of the charging part. The charging station 100 can receive its electricity wirelessly through a wireless receiving device 107 and / or via an underground / built-in cable 108. The charging station can generally be referred to as a bollard, point, pole, pillar, stake, column etc. The loading part does not have to be prismatic and can be in any way arbitrary. The loading part can be monolithic or can be segmented to allow it to collapse telescopically. An
    [042] [042] The vehicle to be charged can be of any type (provided it has a battery, which means any electrical storage device), for example, the vehicle can be fully electric, an electric / internal combustion hybrid or fully powered by internal combustion. Although the preferred modality is related to charging a road vehicle, the system could also be used to charge the battery of any other type of vehicle, for example, aircraft, boats, trains, electric wheelchairs and mobility scooters. Conveniently, the vehicle uses electrical energy to provide its driving force. The vehicle can engage in “Vehicle-to-grid” (V2G) activities by communicating with the grid to return / sell electricity to the grid or accelerate its charging rate.
    [043] [043] The loading system also comprises a base part 102 which defines a recess in which the loading part can be retracted.
    [044] [044] The base part and / or the distal end of the loading part can comprise a load sensor to detect a load.
    [045] [045] The loading system further comprises a retraction mechanism 103. The retraction mechanism can comprise any apparatus suitable for moving the loading part in relation to the base part. Examples include hydraulic, pneumatic, thermal or magnetic drives or a mechanical system that can use one or more scissor mechanisms, gears, rails, pulleys and / or chains. An example comprising a drive 113 acting on a scissor mechanism 114 in a 'scissor monkey' arrangement is shown in Figures 4 and 5. In the telescopic arrangement shown, one end of the scissor mechanism is movably attached to the base part 102 and / or substructure 105 with the other end being movably attached to part 101, while one end of the driver 113 is attached to the base part 102 and / or substructure with the other end being attached to the scissor mechanism 114. It is evident that this arrangement could be applied to examples where the loading part is not telescopic.
    [046] [046] The retract mechanism can be used to cause the loading part to move between an extended position and a retracted position, as appropriate, for example, the loading part can be extended while loading is taking place, but ideally must be retracted when there is no loading. In the preferred embodiment, the retraction mechanism will move the substantially vertical loading portion from a substantially hidden retracted position to an elevated extended position. The system in its extended state is shown in Figures 2 and 5, where the loading part extends out of the base part and in its retracted state in Figures 3 and 4, where the upper part of the loading part is substantially inside the top of the base part.
    [047] [047] The retraction mechanism 103 can be partially (as shown in Figures 4 and 5) or totally inside the loading part. The retraction mechanism may alternatively be completely outside the loading part and simply acting outside the loading part.
    [048] [048] The ability to retract can help prevent the loading part from being an obstacle that may disturb or harm other users in the area, for example, when retracted pedestrians will not be able to enter it and cars will not be able to collide with it. The ability to accommodate the loading part in its retracted state also helps maintain the aesthetic appeal of the environment in which the system is installed, as it will have a lower profile when the loading part is housed.
    [049] [049] More than one retraction mechanism can be used, which can be the same type of mechanism or different mechanisms. This can help to ensure that the forces acting on the loading part during extension are applied as desired (for example, symmetrically) and also reduces the load on each individual retraction mechanism, reducing wear and the need for regular maintenance.
    [050] [050] A 112 controller is used to control the retraction mechanism. The controller 112 can be located in the base part 102 or totally or partially inside the loading part 101. The controller is configured to control the retraction mechanism to drive the loading part from its retracted state to its extended state or from its extended state to its retracted state. These actions can occur in response to various stimuli. These will be discussed in more detail below, but some examples are as follows. The controller can be configured to control the retract mechanism to trigger the loading part from its retracted state to its extended state in response to any one or more of the following factors, in any combination: * A physical user input device associated with the charging station being triggered by a user. The physical user's input device can be a push button or touch screen. It can be on the charging station itself or on a board or nearby operating station.
    [051] [051] The controller can be configured to control the retract mechanism to drive the loading part from its extended state to its retracted state in response to any one or more of the following factors, in any combination: * A physical input device of the user associated with the charging station being triggered by a user. The user's physical input device can be a push button or touch screen. It could be at the charging station itself or at a nearby operating board or station.
    [052] [052] The controller can determine that charging from the charging socket has stopped, for example, by detecting that no current is flowing from the charging socket or by determining that the battery of a connected vehicle is fully charged. The controller can determine if the movement of the loading part is obstructed and to prevent the retraction mechanism from operating if an obstruction is detected. In case the loading part comprises a cable system, the controller can cause the cable to be retracted before the loading part is retracted. You can block the retraction of the loading part if the cable cannot be fully retracted. The controller can cause the charging cable to be wound up before the charging part is moved to the stowed position. The controller can prevent the retraction mechanism from extending if the load sensor detects a load that exceeds a predetermined limit, for example, to prevent damage from trying to extend the loading part when a person or vehicle is blocking it.
    [053] [053] The charging system can also comprise one or more components configured to receive external signals. An underground / embedded cable 108 can be used to transfer data related to user information, weather or information about nearby posts. This cable can also transfer energy to the system or the energy can be transferred using a separate cable. A wireless receiver 107 can be used instead of or in combination with an underground / built-in cable to receive data. Wireless data can be in the form of Bluetooth (RTM), Wi-Fi, NFC (near field communication) or RFID (Radio Frequency Identification Signals). Wireless data can be provided by an Internet server. This wireless receiver device can also receive power which is then transferred to the system or these functions can be performed by two separate receivers. The wireless receiver can be located in the charging or base part or in the retract mechanism. A user interface 109 can also be used to provide and / or receive information to or from a user. The user interface can comprise one or more of: a touch screen, a compact keyboard / keypad, a screen, one or more LEDs. Other external signals may be able to interact with the user interface 109. Such external signals may, for example, be generated in response to the reading of a 1D, 2D or 3D bar code (such as visual ID 111), located at charging station. User interface 109 can provide the user with information about the vehicle status (eg charge level, remaining charge time, time since connection, charge cost) and / or the charging system status (for example , if the system is operating optimally or is damaged in any way, if it is for maintenance).
    [054] [054] In one embodiment, the controller causes the retraction mechanism to retract the loading part if the controller determines that a predetermined period of time has elapsed since the most recent electrical supply. Although a user normally has control over the extent and retraction, it is also advantageous to have an automatic or semi-automatic device to retract the loading part, for example, if the user forgets to retract the loading part after use, if the system has finished loading or is damaged or simply not requiring a user command. The time period after which the retraction occurs can be set to a fixed value, but it can be set alternatively, depending on several factors, which can be used individually or in combination to define the time period. Examples of such factors are: * A user's past behavior, which may have been previously recorded and data recorded in memory. This data is derived from just one user or defined according to the behavior of a large number of users. These data can constitute, for example, the average time between the disconnection of the vehicle and the connection of a subsequent vehicle.
    [055] [055] These factors can influence the length of time before the loading part retracts after loading is complete, individually or in combination. If they are used in combination, some factors may have a greater weight or even completely overcome other factors, for example, if the weather is considered too hot for safe operation, this may exceed the user's preferred time of entry.
    [056] [056] Any of the factors listed above can also be arranged to cause the loading part to retract immediately after loading is complete, that is, a period of time before the retraction equals zero seconds. Other factors, particularly those that can affect a user's safety, such as detecting an increase in the power supplied to the charging station, can cause the charging part to finish charging and / or retract immediately. In the event that wireless charging is taking place, the system can automatically stop charging and retract the charging portion.
    [057] [057] The wireless receiver mentioned above can also be used for control when the retraction mechanism extends the loading part. If the presence of an RFID tag, which may be in the possession of a user, is detected, this could cause the loading part to be extended. Alternatively, an external device in the user's possession (a smartphone, smart watch, car computer system, etc.) can be used to detect the presence of an RFID 110 tag inside the charging system and send signals that take part of loading to be extended. The RFID tag can be located on the base part 102 or totally or partially inside the loading part 101. Likewise, a user can use a device to read a visual ID 111, such as a 1D, 2D or 3D barcode, located at the charging station, which would cause the device to generate a signal indicating that the charging part should be extended.
    [058] [058] Generally, the control of any of the components described above can be implemented in software, firmware, hardware (for example, fixed logic circuit) or any combination thereof.
    [059] [059] The present invention separately discloses each individual characteristic described here and any combination of two or more of these resources, insofar as these characteristics or combinations can be performed based on this report as a whole, in the light of the common general knowledge of that skilled in the art, regardless of whether such features or combinations of features resolve any problems disclosed herein and without limiting the scope of the claims. Aspects of the present invention can consist of any individual feature or combination of features. In view of the foregoing description, it will be apparent to one skilled in the art that various modifications can be made within the scope of the invention.
