    DK 2021 00817 A1 1 Title: Protective pliable bollard Field of the Invention The present invention relates to means of protecting any structure or area from accidental vehicular damage. This objective is achieved by way of a bollard, which is pliable and thus able to withstand the impact of a slow moving vehicle without causing damage to the vehicle or bollard, while preventing unintentional contact with any structure or area in front of which the bollard is placed.
    Background of the Invention As the number of electrical vehicles or hybrid-vehicles is increasing, there is a need for electrical vehicle (EV) charging stations, electric recharging points, or charging points. Such units are provided with electrical Vehicle Supply Equipment (EVSE). Such units may be a part of an element in the infrastructure that supplies electric energy for the recharging of electric vehicles, the unit being provided with plug-in equipment.
    An electric vehicle charging station, also called EV charging station, electric recharging point, charging point, charge point and EVSE (Electric Vehicle Supply Equipment), is an element in an infrastructure that supplies electric energy for the recharging of electric vehicles, including electric cars, neighborhood electric vehicles and plug-in hybrids.
    As plug-in hybrid electric vehicles and battery electric vehicle ownership is expanding, there is a growing need for widely distributed publicly accessible charging stations, some of which support faster charging at higher voltages and currents than are available from residential EVSEs. Many charging stations are on street facilities provided by electric utility companies located or located at shopping centres and operated by many private companies.
    Charging stations fall into four basic contexts: - Residential charging stations: An EV owner plugs in when he or she returns home, and the car recharges overnight. A home charging station usually has no user authentication, no metering, and may require wiring a dedicated circuit. Some portable chargers can also be wall mounted as charging stations.
    DK 2021 00817 A1 2 - Charging while parked (including public charging stations) — a commercial venture for a fee or free, offered in partnership with the owners of the parking lot. This charging may be slow or high speed and encourages EV owners to recharge their cars while they take advantage of nearby facilities. It can include parking stations, parking at malls, small centres, and train stations (or for a business's own employees).
    - Fast charging at public charging stations >40 kW, delivering over 60 miles (100 km) of range in 10-30 minutes. These chargers may be at rest stops to allow for longer distance trips. They may also be used regularly by commuters in metropolitan areas, and for charging while parked for shorter or longer periods.
    - Battery swaps or charges in under 15 minutes. A specified target for CARB credits for a zero-emission vehicle is adding 200 miles to its range less than 15 minutes.
    Battery capacity and the capability of handling faster charging are both increasing, and methods of charging have needed to change and improve. Super chargers are free connectors that charge batteries in minutes instead of hours. Stations are strategically placed to minimize stops during long distance travel and are conveniently located near restaurants, shopping centres, and WIFI hot spots.
    In order to speed up the charging or re-charging effect and thus reducing down-time due to such charging or re-charging, the systems and facilities used are continuously improved, allowing a battery to for example an 80% charge in 30 minutes or less, for example with a charging rate of more the 90 kW. In order to cater for higher charges, there will be a demand for more robust cables, transporting away the heat caused by such volumes of energy over a short time span. Hence, development of liquid cooled charging cables is in progress, enabling handling of such high powered energy without causing detrimental effect or harm to persons handling and disconnecting such cables.
    In general, charging stations are expensive to purchase, install, maintain and repair.
    Commonly, the charging or recharging stations are situated such that a suitable, rechargeable vehicle is parked in close proximity to the charging station when charging. In connection with parking maneuvering, and in view of heavy traffic and large number of vehicles awaiting or queueing for the possibility of access to
    DK 2021 00817 A1 3 such charging stations, there is an inherent risk for accidental vehicular damage to the charging station, inter alia due to existing stress situations. Such damage may also cause serious injury to personnel, users or bystanders.
    Hence, there is a need for means of conveniently protection of charging stations, eliminating or substantially reducing the risk of accidental vehicular damage to the gear and resulting injury to personnel, users or bystanders.
    Means for protecting structures or areas against vehicles are not new, and bollards are often placed around parking lots or along sidewalks in order to prevent vehicular contact with pedestrians, structures or fragile areas. However, existing means of protecting structures or areas against unintentional vehicular damage are generally fixed rigidly to the ground. Contact with a rigid bollard may cause significant damage to a slow moving vehicle, for example during parking maneuvering. Other existing bollards may be fashioned from a fragile material or they may not be fixed to the ground at all. This provides inadequate protection against unintentional vehicular contact, as even a slow moving vehicle will destroy the bollard or render it inoperable.
    Hence, there is a need for means of conveniently and effectively protecting structures or areas against unintentional contact with slow moving vehicles, while also preventing damage to vehicles or bollards.
    Summary of the Invention An object of the present invention is to provide a convenient way of protecting any structure or area against unintentional contact with a slow moving vehicle.
    Another object of the present invention is to eliminate or substantially reduce the possibility of personal injury as a consequence of unintentional contact between a vehicle and a structure or area.
    Yet another object of the present invention is to avoid or at least substantially reduce the risk of causing damage to any structure or area as a consequence of unintentional contact with a slow moving vehicle.
    Yet another object of the present invention is to provide a system for avoiding or at least substantially reducing the risk of causing damage to a vehicle as a
    DK 2021 00817 A1 4 consequence of unintentional contact with the protective means established for protecting structures or areas.
    Yet another object of the present invention is to provide a system for avoiding or at least substantially reducing the possibility of causing damage to the protective means established for protecting structures or areas against unintentional contact with a slow moving vehicle.
    Yet another object of the present invention is to provide a charging station for the charging and recharging the batteries of electric vehicles, where the possibility of causing accidental injury to persons or damage to vehicles, equipment or the protective means established in connection with parking and/or leaving the charging station is eliminated or at least substantially reduced.
    The objects are achieved by means of a pliable bollard as defined in the independent claim, while variants or alternative embodiments are defined by the dependent claims.
    According to the invention, a pliable bollard for the protection of structures or areas against unintentional vehicular contact is provided. The pliable bollard comprises a suitable threaded connection, anchored to a device, which is laterally arranged within the outer walls of the bollard. The outer walls of the bollard extend below the laterally arranged device, forming a skirt spanning the circumference of the lower end of the bollard. A suitable washer is arranged so that it surrounds the threaded connection. The washer is limited upward by the laterally arranged device and surrounded by the skirt, while also extending below the skirt. The pliable nature of the bollard according to the present invention, will allow the bollard to withstand the impact from a slow moving vehicle without causing damage to the bollard or the vehicle, while protecting the structure or area in front of which the bollard is situated against unintentional vehicular contact.
    According to an embodiment of the invention, the bollard may be made of powder coated, hot-dipped galvanized steel.
    According to an embodiment of the invention, the bollard may be fixed to the base structure or ground by a suitable threaded connection and provided with a neoprene washer surrounding the threaded connection, intended to be arranged between the lower end of the bollard and the upper surface of the base structure or
    DK 2021 00817 A1 ground, serving as an intermediate flexible part between the bollard and the base structure or the ground.
    The neoprene washer may for example have a thickness of 10-30 mm and the neoprene may be configured such that it may be compressed by 2-6 mm, when the 5 bollard is fixed to the base structure or the ground, providing a gap of 1-2 mm between the lower end of the bollard and the base structure or the ground.
    According to an embodiment of the invention, at least one of the provided bollards may be placed in front of a charging station for electric vehicles, protecting said charging station against accidental vehicular damage in connection with parking and/or leaving the charging station.
    It should be noted that the charging station also may comprise an electric source, a charging unit supported by base structure or a ground, the charging unit being provided with a cable, the end of which being provided with an end plug configured to be connected to a connector on the vehicle or with at least one plug-in point for plugging in an end to a charging cable from the vehicle. The base structure may preferably also be provided with a surface layer of a soft, resilient material, securing that an end plug is not damaged if it unintentionally is dropped o to the ground or base structure in front of the charging point. The bollards installed may preferably be positioned on top of and fixed to the base structure below such resilient mat or material, so as to reduce the possibility of causing vehicular damage to the charging station, particularly in connection with parking.
    Because the at least one bollard is situated in front of the charging point and fashioned in such a way that it is resilient against impact from slow moving vehicles, it will effectively eliminate or at least substantially reduce the risk of vehicular damage to the charging station. As a consequence, the risk of serious injury to users or personnel due to damaged charging equipment is eliminated or at least substantially reduced correspondingly.

    Description of preferred embodiments of the Invention The following description of the exemplary embodiment refers to the accompanying drawings. The same reference numbers in different drawings identify the same or similar elements. The following detailed description does not limit the invention. Instead, the scope of the invention is defined by the appended claims.
    Reference throughout the specification to “one embodiment” or “in an embodiment” means that a particular feature, structure, or characteristic described in connection with an embodiment is included in at least one embodiment of the subject matter disclosed. Thus, the appearance of the phrases “in one embodiment” or “in an embodiment” in various places throughout the specification is not necessarily referring to the same embodiment. Further, the particular features, structures, or characteristics may be combined in any suitable manner in one or more embodiments.
    Figure 1 shows schematically in perspective a view of an embodiment of a fast public charging station 10. The station shown comprises a protective shed 11 resting on a base structure 12. The base structure 12 as such is preferably made of concrete, preferably with an anti-slippery surface. The protective shed 11 comprises a roof structure 13, and vertical walls 14 arranged on three sides of the shed 11.
    Access to the shed is from the front side. On the base structure 12, beneath the roof structure 13, two charging racks 15 with female connectors (not shown) for connection with a male plug are arranged. The station 10 may be configured with
    DK 2021 00817 A1 7 parking lanes 16, each positioned in front of the charging racks 15. As indicated, a vehicle 17 may be parked in the parking lane 16 in front of one of the charging racks
    15. On both sides and in front of each of the charging units 15, the base structure 12 is provided with bollards 18. The bollards 18 are positioned such that they will be hit by a vehicle 17, which, during parking and/or leaving, has moved too far toward the charging rack 15. The charging units 15 may be of the super charging type with multiple charging points. Figure 2 shows schematically in perspective a possible configuration of an embodiment of the base structure 12, suitable for use in connection with a fast public charging station 10 of the type disclosed in figure 1, also showing the bollards 18. Figure 3 shows schematically a top view of the base structure 12 shown in figure 2. As shown, the base structure 12 is provided with two foundation recesses 15’ for the charging units 15. At each corner and along the back side the base structure 12 is provided with holes or embedded elements 19 for fixing the supporting structure 20 of the protective shed 11 to the base structure 12. Moreover, the base structure 12 may also be provided with a recess 21 forming a well for the infra structure. As shown in the Figures, the base structure 12 is provided with bollards 18 placed on each side and in front of each of the charging units 15. The bollards 18 may be made of powder coated, hot-dipped galvanized steel, and fixed to the ground by at least one bolt 23. Surrounding the bolts 23 are neoprene washers 22, 20 mm thick, which are compressed by 4 mm, providing traction and reducing the risk of the bollards 18 coming lose from the base structure 12. The bollards 18 are fixed to the base structure 12 such that there is a gap 24 of 1 mm between the base structure 12 and the bollards 18, allowing some movement of the — bollard before the edge of the bollard hits the base structure 12 and thus reducing the risk of damage to bollards 18 or vehicles 17. The gap 24 may be formed by extending the plate forming the surface body of the bollard 18 down below a laterally arranged device 25 at the lower end of the bollard 18, serving as fixing point or attachment for the bolt 23, but ending above the lower end of the neoprene washer 22 when assembled at the lower end of the bollard 18, thus creating a periphery skirt 26 at the lower end of the bollard. The bolt 23 extends a distance below the
    DK 2021 00817 A1 8 periphery skirt end of the bollard plate and also down below the neoprene washer
    22.
    Figure 4 shows a vertical cross section of the bollard 18 with the bolt 23, laterally arranged device 25, periphery skirt 26 and washer 22. Figure 5 shows a detailed view of the bollard 18, with the bolt 23, washer 22, laterally arranged device 25 and periphery skirt 26, fixed to a base structure 12, such that there is a gap 24 between the base structure 12 and the periphery skirt 26.
    As indicated in Figure 1, the shed is of a simple weatherproof type. It should be appreciated that the shed may be substituted by a more closed, dry and warm housing type with external with a number of charging points while the interior is suitable for longer stays under warm and dry conditions.
    As shown in the Figures, the bollard 18 has a circular cross sectional area. It should be appreciated however, that the bollard 18 may have any suitable cross sectional area, preferably, but not necessarily without any sharp corners causing damages to a vehicle bumping unintentionally into a bollard. An alternative cross sectional area may for example have a polygonal cross sectional area.
    Moreover, it should be appreciated that the height of the bollard may be such that the top is higher than the lower end of a vehicle.
    According to one embodiment the height of the bollard 18 may be chose to be so large the top of the bollard 18 will be visible from the driver seat when approaching the charging station.
    The end fixation point in the supporting base structure 12 may be of a type securing fixing of the threaded bolt in an appropriate manner.
