Description

Electrical supply device The present invention relates to an electrical supply device, and in particular but not exclusively to an electrical supply device for charging an electric vehicle.
Electrically powered vehicles, including both private and public service vehicles, are becoming increasingly popular owing to their low environmental impact.
However, electric vehicles generally have a very limited range as compared to petrol or diesel fuelled vehicles. Therefore, to encourage further use of electric vehicles, it is : : essential to provide charging points in publically accessible locations (for example hospitals, hotels and supermarkets), as well as at private homes, so that the users of those S...
vehicles can recharge them readily, both between journeys and also en route. S... * S
* C5 Because electric charging points for electric vehicles must be capable of providing large electrical currents and of necessity are generally located in public places, it is important S.....
that they should be strong and safe to use, and capable of withstanding the rigours of poor ** weather, accidental or deliberate damage and misuse. Where the user is to be charged a fee for use of the charging point, it is also important that this should be provided for and that use without payment of the appropriate fee should be prevented.
Various designs have been proposed for public charging points. Often, these charging points take the form of a post that is mounted by the side of a road or a public parking bay.
The post carries a socket into which a charging lead for the vehicle can be plugged.
Usually, a hinged door is provided, which can be opened to provide access to the socket, and then closed and locked after insertion of the charging lead to prevent unauthorised removal. The locking mechanism for the door may be linked to a fee payment system, which prevents access to the socket unless the appropriate fee has been paid. The door also helps to protect the socket from rain and snow, and from accidental or deliberate damage and misuse.
One disadvantage of this type of charging point is that the hinged door is vulnerable to damage and can sometimes be broken off, leaving the socket and/or the inserted charging lead exposed. This creates a risk of damage to the socket and/or the lead, and possibly gives rise to a risk of electrical shock. Furthermore, if the door is removed, the socket may then be exposed to rain or snow.
It is an object of the present invention to provide an electrical supply device that mitigates at least some of the aforesaid disadvantages.
According to the present invention there is provided an electrical supply device including a housing having a compartment with a window that provides access to the compartment, an *: electrical socket mounted on a movable wall of the compartment, and a drive mechanism * connected to the movable wall, said drive mechanism being operable to adjust the position of the socket between a first position in which it is accessible through the window and a second position in which it is inaccessible. *
*:..: The drive mechanism allows the socket to be shifted to position in which it cannot be :. accessed by a plug, so preventing unauthorised use of the device. This also protects the socket from damage and from snow and rain. It also reduces the risk of foreign objects being inserted into the socket. Furthermore, after a plug has been inserted into the socket, it is driven to the inaccessible position, which prevents the plug from being removed by an unauthorised person. The use of a hinged door, which is vulnerable to damage, is thus avoided.
Advantageously, the socket is mounted within a sliding wall of the compartment.
Advantageously, the wall is ananged for vertical movement between a lower position in which the socket is accessible and an upper position in which the socket is inaccessible.
Advantageously, the socket is positioned at least partially above the upper edge of the window when it is located in the inaccessible upper position.
Advantageously, the electrical supply device includes an electrical supply system for supplying electrical current to the socket and a control system for controlling the supply of electrical current to the socket, wherein the control system is constructed and arranged to disconnect the electricity supply from the socket when the socket is in the accessible position.
Advantageously, the electrical supply device includes a fee charging device for charging a fee to a user of the system.
Advantageously, the electrical supply device includes an indicator device for indicating the status of the system. * * * *. .
* * Advantageously, the electrical supply device is mounted within a vertical post structure.
Certain embodiments of an electrical supply device will now be described, by way of S.....
* 20 example, with reference to the accompanying drawings, in which:
S
S..... * S
*:. Figure 1 is a sectional side view of a first electrical supply device, Figure 2 is a front view of the first electrical supply device, in partial cross-section, Figure 3 is a front view of a second electrical supply device, Figure 4 is a partial front view of the second electrical supply device in a first configuration, Figure 5 is a partial front view of the second electrical supply device in a second configuration, and Figure 6 is a partial front view of the second electrical supply device in a third configuration.
The electrical supply device shown in figures 1 and 2 comprises a housing 2 that can be secured to an anchor point 4, for example with a bolt 6. The anchor point 4 may be provided on a support post or alternatively it may be embedded in the ground.
The housing 2, which may for example be made of steel or another suitable material, includes a generally cylindrical circumferential wall 8 and a closed top plate 10. A domed top cover 12, made for example of glass or a clear plastics material, is attached to the top plate 10 by bolts 14.
A section of the cylindrical wall 8 is cut away to form a window 16 in the front part of a housing. Internally, the housing 2 is divided into two parts by a vertical dividing wall 18 and an inclined dividing plate 20 that extends downwards from the lower end of the vertical dividing wall 18 to the lower edge of the window 16. The internal volume of the housing 2 is thus divided into an open part 22 that is accessible through the window 16 and an inaccessible closed part 24 that is enclosed by the cylindrical wall 8, the dividing wall * : 18 and the dividing plate 20. * .
The vertical side edges of the dividing wall 18 are mounted in runners 26 formed on the *.*.
inner surface of the cylindrical wall 8. These runners 26 allow the wall 18 to slide S.....
* 20 vertically within the housing 2. A drive mechanism (not shown) is provided for setting the * * vertical position of the wall 18 according to control signals received from a control system (not shown).
An electrical socket 28 is mounted in an aperture of the dividing wall 18 and has a front face that is accessible from the open part 22 of the housing 2, into which a plug 30 of a vehicle charging lead can be inserted. The rear part of the socket 28 extends into the closed part 24 of the housing and is connected to an electrical supply system (not shown).
The socket 28 moves vertically with the plate 18 between a lower position shown in continuous lines and an upper position 28' shown in broken lines. When the socket 28 is in the lower position, it is aligned with the window 16, allowing the plug 30 to be inserted or removed. When the socket 28' is in the upper position, it is positioned at least partially above the upper edge of the window 16, which prevents access to the socket. When the socket is in this upper position, a plug 30' that has already been inserted cannot be removed. Likewise, an unplugged plug cannot be inserted into the socket until the socket 28 has moved down to the lower position.
The electrical supply device includes an electronic control system (not shown) for controlling operation of the device, including, for example, controlling the flow of electrical current to the socket 28, controlling operation of the drive mechanism that adjusts the vertical position of the plate 18 and the socket 28, charging a fee to the user (if required), and indicating the operational status of the charging device by means of one or more illuminated indicators 32 located beneath the transparent top cover 12. The control system is largely conventional and will not therefore be described in full detail. However, some aspects of its operation will now be discussed.
When the electrical supply device is not in use, the drive system sets the vertical wall 18 to the upper position, so preventing access to the socket 28'. In this position, a plug 30 *:::: cannot be inserted into the socket. The socket 28' is also protected from rain and snow and * * it is hidden from view, reducing the risk that children or others will try to insert fingers or * other objects into the socket. The electrical supply to the socket is also turned off to ensure * that there is no risk of electrical shock.
** SS S. * 20 * : ...: When a user wishes to recharge a vehicle, the electrical supply device must first be :. activated. This may be done in various ways according to the circumstances for which it is intended. For example, if the electrical supply device is intended for public use, it may be activated by instigating a procedure for charging a fee to the user. This could be done for example by inserting a credit card or payment card, inserting coins or a token, using a keypad to enter a personal identification number (PIN) allowing access to a back account, or electronically, for example using a mobile phone. If the electrical supply device is intended for private use, it may simply have an on/off switch and/or a locking mechanism such as a key or a device for entering a security code that prevents unauthorised use by others.
Once the electrical supply device has been activated, the drive mechanism drives the sliding plate 18 downwards to the lower position in which the socket 28 is accessible through the open window 16. The plug 30 of a vehicle charging lead can then be inserted into the socket 28.
Once the plug has been inserted, the drive mechanism drives the sliding plate 18 back upwards to the upper position in which the socket 28' and the plug 30' are located at least partially above the upper edge of the window 16. This prevents the plug 30' from being removed from the socket 28'. The control system then activates the charging system, which supplies an electric current to the socket so as to recharge the vehicle.
When charging has been completed, the control system deactivates the charging system to cut-off the supply of electric current to the socket. It then activates the drive mechanism, which lowers the plate 18 and the socket 28 to the lower position, allowing the plug 30 to be removed. Alternatively, after cutting off the supply of electric current, the socket may .. : be held in the upper position to prevent removal of the plug until the control system *::: :* receives an appropriate control signal from the user. This may be achieved for example by reinserting a credit card or entering a PIN on a keypad. This prevents unauthorised * S... removal of the plug and the charging lead.
S..... * 20
* . . The control system also controls operation of the indicator lights 32 so as to indicate, for *:. example, that the electrical supply device is available for use, charging is taking place, or that charging has been completed.
A second embodiment of the electrical supply device is shown in Figures 3-6. This device is similar in many respects to the first embodiment of the invention and so will not be described in great detail.
The electrical supply device 40 is attached to the upper end of a post 42 that is embedded in the ground. In this embodiment, the open part of the housing that is accessible through the window 44 includes a vertical rear wall 46, two side walls 48 that extend forwards from the edges of the rear wall to the side edges of the window 44, an inclined lower plate and a horizontal upper plate 52. The socket 54, which in this embodiment is intended for use with a British 3-pin plug, is mounted on a sliding panel 56 that is located behind a slot 58 in the rear wall 46. The position of the sliding panel 56 and the socket 58 can be adjusted between an upper position shown in Figure 4 and a lower position shown in Figure 6. When the socket 58 is in the lower position shown in Figure 6 it is accessible through the window 44, allowing a plug to be inserted or removed. When it is in the upper position shown in Figure 4, the socket 54 is aligned with the horizontal upper wall 52, which prevents access to the socket and prevents an already inserted plug from being removed. A small clearance is provided between the rear edge of the upper wall 52 and the rear wall 46, to accommodate a plug that has been inserted into the socket 54.
In this embodiment, the inclined lower plate 50 carries a device 60 for receiving a token or a credit card, allowing the user to pay a fee for use of the electrical supply device.
Various modifications of the electrical supply device described herein are of course : possible and will be apparent to a person skilled in the art. Furthermore, the electrical *::: * supply device described herein may also be used for other purposes, for example for supplying electricity to caravans or boats, or at camping sites. *.. * *
