Description
Electric Vehicle Charging System The present invention relates to an electric vehicle charging system. More particularly the present invention relates to a retractable charging system installed in a sub-vehicle surface, and a vehicle having a charging receptacle for such a system.
Elecfrically powered or "zero emission" vehicles and part-electrically powered (hybrid) vehicles are becoming increasingly common. A problem with such vehicles is the charging of on-board electrical storage means. Unlike liquid fuel powered vehicles, transfer of electrical charge into an onboard battery of an electric vehicle is slow, in particular when using a conventional single phase domestic power supply.
This is a problem because many electric vehicles have a limited range and charging may be required during a journey. Therefore charging can significantly increase journey times.
In addition, known electrical charging systems require user intervention to plug in the vehicle in to the power supply. This restricts the amount of power that may be transferred without causing unnecessary risk to the user. It is also an inconvenience to the user and may even be forgotten.
It is an aim of the present invention to provide an improved electric vehicle charging system.
According to a first aspect of the invention there is provided an electric vehicle charging system comprising a charging element movable from an extended position to a refracted position within a sub-vehicle surface.
Preferably the majority of the charging element is under the sub-vehicle surface in the retracted position. More preferably the charging element does not protrude from the floor surface in the retracted position.
Preferably the charging element comprises a vehicle electrical contact disposed at a first end for contact with a corresponding electrical contact of a vehicle.
Preferably the charging element comprises a conductive elongate body sheathed to expose the vehicle electrical contact proximate the first end. Preferably the conductive elongate body is sheathed in an electrically insulating material.
Preferably there is provided a power supply contact positioned below the sub-vehicle surface, the power supply contact configured for connection to an electrical power supply, wherein in the retracted position no electrical contact is made between the charging element and the power supply contact, and in the extended position electrical contact is made between the charging element and the power supply contact.
Preferably there is provided a seal between the charging element and the sub-floor surface to prevent the passage of fluids to below the sub-floor surface.
Preferably the charging element comprises a feed contact and an electrically insulating surface, wherein in the retracted position the electrically insulating surface contacts the power supply contact, and in the extended position feed contact contacts the power supply contact. Preferably the feed contact is positioned at an end of the charging element. Preferably the power supply contact is a sleeve positioned around the charging element. Preferably the electrically insulating surface is an insulating coating on the charging element.
Preferably the charging element is an elongate member and is axially extendable
and retractable.
Preferably the charging element is circular in cross section. More preferably the charging element in tubular.
The charging element may be inflexible. Alternatively the charging element may be telescopic. The charging element may be deformable between the extended and retracted positions. In this case the charging element may be surrounded by a flexible boot.
Preferably the charging element is configured to resile to the retracted position.
Preferably the charging element comprises a magnetic portion.
The charging element may comprise an electromagnet.
The charging element may comprise an induction coil disposed at a first end for power transfer to a corresponding induction coil of a vehicle.
A wireless data reader may be provided to identify a wireless data tag of a vehicle being charged.
The charging system may comprise a wireless data tag comprising identification data of the charging system.
According to a second aspect of the invention there is provided an electric vehicle comprising a charging element positioned proximate an underside of the vehicle.
The charging element may be movable from an extended position in which the charging element extends from the underside of the vehicle to a retracted position proximate the underside of the vehicle, In this way, a stationary charging receptacle can be positioned within a sub-vehicle surface to contact the charging element extended from the vehicle.
Preferably in the retracted position the charging element is retracted within an underside surface of the vehicle.
Preferably he charging element is an electrical contact. Preferably electrical contact is an electrically conductive plate.

Preferably there is provided a power meter configured to record the amount of power transmitted to an electric vehicle during charging.
Preferably there is provided a timer configured to record the amount of time taken to charge an electric vehicle.
According to a fourth aspect of the invention there is provided an electric vehicle comprising a charging element and a wireless data reader configured to identify a wireless data tag of a vehicle charger proximate the vehicle.
By electric vehicle we mean a vehicle which can store electrical energy and is at least partly propelled by electrically powered actuators. Such vehicles may have alternative means for propulsion (e.g. internal combustion engines) and therefore may be hybrid vehicles.
An example electric vehicle charging system will now be described in accordance with the present invention and with reference to the accompanying drawings in which:-Fig. 1 a is a schematic view of a first electric vehicle charging system in accordance with the present invention; Fig.lb is a schematic view of the charging system of Fig.la in a second configuration, Fig. 1 c is a schematic view of a charging system of Fig. 1 a in a third configuration, and Fig.2 is a schematic view of a second charging system in accordance with the present invention.
Referring to Fig. 1 a, an electric vehicle charging system 100 is shown. The system 100 is shown embedded in a sub-vehicle surface 102, which in this case is the ground surface of a parking garage. The electric vehicle charging system 100 comprises a charging element 104 and a power supply subassembly 106. The charging element 104 comprises a hollow metal cylinder 108 having a first end 110 and a second end 112. The cylinder 108 is coated with an insulating material coating 114 from the first end 110 to a boundary 116 partway along its length. An annular region 118 at the first end 110 is uncoated. The power supply subassembly 106 comprises a conductive collar 120 having a first end 122 and a second end 124. The first end 122 is positioned proximate the surface 102, whereas the second end 124 is buried below the surface 102. An insulating ring 126 is positioned between the first end 122 of the collar 120 and the surface 102. As such, the conductive collar 120 is not exposed to the surface 102. The conductive collar 120 is charged by way of a three-phase electric supply 128.
According to the invention there is also provided a vehicle (not shown) which comprises a conductive plate 130 on its underside connected to a vehicle battery 132 such that the battery 132 can be charged by applying an electrical charge to the conductive plate 130.
The charging element 104 is arranged such that it is movable within the conductive collar 120 in an axial direction A. In the retracted position shown in Fig. 1, the insulating material coating 114 of the charging element 104 contacts the entire inner region of the conductive collar 120. Therefore, no electrical connection is made between the cylinder 108 and the conductive collar 120. When a vehicle is positioned over the electric vehicle charging system 100 the charging element 104 can be deployed axially in the direction A towards the conductive plate 130 of the vehicle.
Fig. lb shows an intermediate position of the charging element 104 whereas Fig. 1 c shows the charging element 104 in a position in which the annular region 118 is contacting the conductive plate 130. It will be noted that the boundary 116 has passed the second end 124 of the collar 120. Therefore the cylinder 108 is in electrical connection with the conductive collar 120 in this position and as such current can flow from the conductive collar 120 through the cylinder 108 to the conductive plate 130 and consequently charge the battery 132. It will be noted that in this position the only exposed surfaces of the charging element 104 are those protected by the insulating material coating 114. The annular region 118 is in contact with the conductive plate 130 and thus only a very small or non-existent amount of conductive charged material is exposed.
Once the vehicle has finished charging the charging element 104 is retracted to the position of Fig. 1 a and the vehicle can be driven away safely.
The charging element 104 may be deployed and retracted in a number of ways.
In the above embodiment the charging element 104 comprises a permanent magnet proximate the first end 110. Once the user of the vehicle has deactivated the ignition, an electromagnet within the underside of the vehicle is activated thus drawing the permanent magnet of the charging element 104 towards the conductive plate 130.
The permanent magnet may be constructed from a plurality of magnetic elements held within a matrix coating the first end 110 of the charging element 104.
Alternatively, the charging element 104 may be powered by a motor or linear actuator driven by a control circuit responsive to the presence of a vehicle above the surface 102.
According to the invention, the electric vehicle charging system 100 is provided with a vehicle recognition system comprising an RFID chip reader capable of reading an RFID chip mounted inside the vehicle (or within the user's key). The system is also provided with a meter which can calculate the amount of power consumed by the vehicle during the charging process and communicate such information to a provider who can bill the vehicle owner appropriately. The vehicle recognition system may interface with the vehicle's existing wireless communication systems (e.g. Bluetooth RTM).
Turning to Fig.2 an alternative charging system 200 is shown which has some common components with a charging system 100. Such common components are number 100 greater. In the electric vehicle charging system 200, the cylinder 208 does not move within the conductive collar 220. Rather a charging plate 234 is provided in electrical connection with the cylinder 108 by virtue of a conductive shaft 236 which is slidable within a bore 238 within the cylinder 208. The conductive shaft 236 is concealed by a flexible, extendable rubber boot 240 which can extend and retract as the charging plate 234 moves.
Variations of the above embodiments may fall within the scope of the present invention. For example, the charging element may comprise one or more rods which lie flat on or just under the surface of the surface 102 and pivoted about one end such that the other end rises to contact the conductive plate 130. Alternatively, a scissor-type linkage arrangement may be provided between a charging plate and an electrical supply to extend the charging element towards the conductive plate.
In addition to the above it will be understood that contact is not necessarily required between the charging element and the vehicle. For example, the invention may be used to bring a charged induction coil of the charging element closer to an induced coil able to charge the battery of a vehicle.
The sub-vehicle surface need not be a ground surface, but may be any horizontal surface positioned proximate a car supporting surface. For example, the sub-vehicle surface may be the top surface of a sub-vehicle charging unit, mat or plate.
A proximity detector may be positioned within the vehicle to alert the driver to the correct position of the vehicle over the charging element.
A single phase (domestic) power supply may be used instead of a three-phase supply.
The system may be powered by an on-site power generator.
The system may be configured with the retractable charging element positioned within the underside of the vehicle. The element can therefore extend to contact the power supply embedded within the sub-vehicle surface.
Alternatively, both the vehicle and the sub-vehicle surface may comprise extendable charging elements which mate between the vehicle and the sub-vehicle surface.
