Description
Frost formation prevention composition and kit
Field of the invention [0001] The present invention relates to anti-frost compositions for the prevention of frost formation in electrical sockets and connectors for charging electrically-powered or hybrid power vehicles, to dispensers for such compositions, and to kits of parts for preventing frost formation on electrical connectors and for chemically de-icing electrical connectors.
Background art [0002] Hybrid power and electrically-powered vehicles are becoming increasingly favored by consumers worldwide as their cost-effectiveness increasingly approaches that of their internal combustion engine counterparts. [0003] As national governments seek to reduce reliance on fossil fuels, it is expected the prevalence of vehicles at least partly powered by electrical energy will be significant in the near future. The strong interest in minimizing reliance on fossil fuels has led to the creation of incentives in several countries at both the national and local level looking to promote the adoption of these vehicles as a reliable alternative to the traditional vehicle. This has resulted in the provision of attractive amenities for the end consumer such as tax allowances, preferential parking facilities, and public charging stations. Such public charging stations may be located in spaces such as in parking lanes along city streets and in parking garages, as well as in traditional gasoline stations along highways.
[0004] These types of vehicles are also increasingly popular in the Northern hemisphere, in particular Scandinavia, Northern Europe and North America. These geographical areas are characterized by relatively strong winters. In particular, the harsh winters in Canada and Scandinavia have significant impact on vehicle function, and precautions must be taken accordingly.
[0005] Users of these vehicles will frequently resort to recharging the vehicle’s battery at outdoor public charging stations in which the electrical connection point is exposed to the elements. Such exposure can naturally lead to problems such as frost and ice formation in or around the electrical connection point during particularly cold and/or humid weather, and in particular when the temperature crosses freezing point level, as the moisture that penetrates the connection area and accumulates on the external connection area freezes. The presence of frost in or around the electrical connection point can be detrimental, significantly decreasing the charging rate, and may also cause difficulty when removing the plug if it has frozen in place.
[0006] Although a more unlikely scenario, these problems may also arise with charging points in dwellings if the electrical connection point is exposed to the elements.
[0007] Therefore, it is an object of the invention to provide means to effectively address the aforementioned problems.
Summary of the invention [0008] According to the present invention, a composition for prevention of frost formation in an electrical connector is provided, the composition comprising a desiccant component and an electrically conductive component.
[0009] Such a composition advantageously prevents the formation of frost during exposure of the electrical connection point to subzero temperatures when it is applied to the electrical connector. The desiccant component effectively absorbs moisture from the surrounding environment so that it prevents the accumulation of moisture at the points of application of the composition. By removing moisture on the connector, formation of ice or frost is effectively prevented.
[0010] Examples of desiccants which may be used as the desiccant component, or as part of the desiccant component, include but are not limited to calcium chloride, silica gel, talcum powder, and similar compounds.
[0011] However, the electrical isolating nature of the desiccant component material may interfere with electrical conduction functionality in the connector. In order to minimize this interference, the composition is thus further advantageously provided with an electrically conductive component.
[0012] Examples of electrically conductive materials which may be used as the electrical conductive component, or as part of the electrical conductive component, of the composition according to the invention include but are not limited to copper, silver, ruthenium oxide, ruthenium dioxide, and similar elements and compounds.
[0013] The electrically conductive component may have a conductivity of at least 1x10E6 S/m, preferably at least 30x10E6 S/m, and more preferably at least 50x10E6 S/m. The better the conductivity properties of the electrically conductive component the greater the neutralization of the electrical isolation effect of the desiccant component. Thus, elements or compounds exhibiting higher electrical conductivity are preferred.
[0014] The electrically conductive component may comprise at least one of silver, copper, annealed copper, graphene, tungsten, aluminium, ruthenium oxide, ruthenium dioxide, bronze, iron, steel, a steel alloy, gold, brass, mercury, graphite, carbon, or any combination thereof. Any element or compound with electrical conduction ability may be employed as the electrical conductor component, preferably elements and/or compounds with superior electrical conduction properties.
[0015] In a preferred embodiment, the desiccant component comprises a material with a hygroscopicity level resulting in 100% moisture absorption per gram of mass. Hygroscopicity refers to the ability of a material to absorb humidity from its surroundings. A hygroscopic substance will actively attract and absorb water, without chemical bonding, such that its chemical structure is not compromised and its moisture absorbing function is retained throughout the absorption activity. This level of hygroscopicity maximizes the moisture absorption effect provided by the desiccant component. The desiccant component preferably absorbs all moisture that reaches the area of the electrical connection component where the frost formation prevention composition has been applied.
[0016] In an embodiment, the desiccant component and the electrically conductive component are both provided in a granulated form, comprising particles with a mean particle size between 0,01 and 50 microns. The size of the particles is preferably such that an even and thorough coating of the composition can be easily achieved on the electrical connector.
[0017] In an embodiment, the composition is inert at a temperature range between -40 and 80 degrees Celsius. This advantageously allows for a composition that is effective throughout a range of thermal conditions, including the subzero temperatures to which the electrical connector of the vehicle may be exposed.
[0018] Furthermore, as the composition is provided in a container, or in a container as part of a kit of parts, intended to be left inside the vehicle indefinitely for convenience, it is preferable that the frost formation prevention composition as well as the de-icing composition are able retain their chemical integrity and functionality regardless of exposure to extreme heat or humidity, both of which are conditions that may arise in hermetically closed vehicles. This property also as a fire hazard prevention in extreme heat conditions.
[0019] In an embodiment, the composition is a homogeneous mixture of the desiccant component and the electrically conductive component. This advantageously allows for a consistent proportion of the components throughout the composition and thus results in a substantially even distribution of the functional components.
[0020] In an embodiment, the composition further comprises an anticaking agent. This advantageously prevents the formation of clumps in the composition.
It may alternatively or additionally comprise further components for attaining complementary functions or enhancing the function(s) of the composition. For example, a glidant, such as fumed silica or magnesium carbonate or similar compounds, could be added to the composition in order to promote powder flow and reduce interparticle friction and cohesion in the case the composition is provided as a granular material.
[0021] In a preferred embodiment, the composition consists only of the desiccant component and the electrically conductive component. This advantageously increases the effectiveness of the composition per applied volume unit, as the main functional components will be present in the composition at a greater density and ratio in comparison to other implementations of the composition.
[0022] In another preferred embodiment, the composition consists essentially of the desiccant component and the electrically conductive component. That is, specific further components can be present, namely those not materially affecting the essential characteristics of the composition. For example, a glidant, such as fumed silica or magnesium carbonate or similar compounds, could be added to the composition in order to promote powder flow and reduce interparticle friction and cohesion in the case the composition is provided as a granular material.
[0023] In another aspect of the invention, a kit of parts is provided comprising a first dispensing container containing the frost formation prevention composition according to any of the above embodiments, and a second dispensing container comprising a de-icing composition.
[0024] By de-icing composition it is meant herein any composition, such as de-icing fluid, that is capable of chemically removing frost or ice from a surface. Such a kit advantageously allows the end user to shield the electrical connector from frost formation, while providing means for frost or ice removal in case of frost formation in the vicinity of the connector, such as in the external areas directly exposed to the environment.
[0025] The frost formation prevention composition is also suitable for depositing on the external parts of the electrical connector, although such use is not deemed as critical as its application on the electrical connector itself, as electrical conduction and charging are not substantially affected by frost formation on the external areas of the electrical connector.
[0026] Moreover, the frost formation prevention composition may be suitable for use in any other type of vehicles, facilities, or devices in which an electrical conduction means may be negatively affected by frost or ice formation.
[0027] The dispensing element of the first dispensing container may, for example, comprise an atomizer or spraying device for dispensing powdered or granular materials.
[0028] In a further embodiment of the kit, such a dispensing element may comprise a sifting element for sifting the composition prior to dispensation or as it is dispensed. This advantageously results in a finer and more even distribution of the composition when the composition is provided in granular form as the sifting element will break up any clumps that may have formed in the granular material in the container. The sifting element may be such that it breaks down any clumps of particles to a maximum size to ensure a desired coating effect.
[0029] Spraying and depositing the composition through such a dispenser advantageously ensures the composition is sufficiently evenly applied such that it creates a coating of composition, which prevents the formation of frost and thus minimizes detrimental impact to the electrical conduction between the charging station and the battery of the vehicle.
[0030] In a preferred embodiment, the de-icing composition is inert through a temperature range between -40 and 80 degrees Celsius. This advantageously ensures proper functioning of the de-icing composition at the subzero temperatures that may lead to frost or ice formation on the external areas of the connector.
[0031] The provided kit is preferably left in the vehicle as part of a safety kit for emergency situations. A user can spray the electrical connector prior to connecting it to the power outlet, thereby forming a protective coating of product on the connection element which will effectively act as a frost shield.
Brief description of the drawings [0032] The present invention will be discussed in more detail below, with reference to the attached drawings, in which: [0033] Figure 1 shows a schematic drawing of a dispensing container containing a composition according to an embodiment of the invention.
[0034] Figure 2 shows a kit of parts comprising first and second dispensing containers according to an embodiment of the invention.
Description of embodiments [0035] According to the invention, a composition comprising a desiccant component and an electrically conductive component is provided.
[0036] Such a composition may be conveniently provided as a granular material in a dispensing container such as the dispensing container 1 shown in Figure 1. The dispensing container 1 contains a frost formation prevention composition 5, and may comprise a dispensing element 2, 3 consisting of a nozzle 3 and an actuator 2. A sifting element 11 (shown in phantom) may be provided in the dispensing container in order to sift the granular material composition prior to or during the dispensing thereof. The actuator 2 may also simultaneously actuate the sifting mechanism thus causing the composition to be sifted as it is being dispensed. A user can thus dispense the composition via the dispensing container 1 in order to apply it to the surface of an electrical connector prior to connecting it to a power outlet. This will effectively prevent the formation of frost or ice in the electrical connector when it is expose to temperatures that would normally cause freezing of any moisture accumulated in the connector. Thus, the charging rate will not be affected by cold weather.
[0037] According to a further embodiment of the invention, a kit of parts is provided as shown in Figure 2.
[0038] The kit of parts 6 shown in Figure 2 comprises a first dispensing container 1 containing the frost formation prevention composition 5 together with a second dispensing container 8 containing the de-icing composition 9 in form of a de-icing fluid. The second dispensing container 8 contains a de-icing nozzle 10. A sifting element 11 (shown in phantom in Figure 1) may be provided in the dispensing container 1 in order to sift the granular material composition prior to or during the dispensing thereof. The actuator 2 may also simultaneously actuate the sifting mechanism thus causing the composition to be sifted as it is being dispensed. A user can thus dispense the composition via the dispensing container 1 in order to apply it to the surface of an electrical connector prior to connecting it to a power outlet. This will effectively prevent the formation of frost or ice in the electrical connector when it is expose to temperatures that would normally cause freezing of any moisture accumulated in the connector. Thus, the charging rate will not be affected by cold weather.
[0039] Moreover, according to this exemplary embodiment, the user may apply the de-icing composition on the external surface of the electrical connector if needed upon retrieval of the vehicle from the charging station. Thus the kit conveniently provides effective means of maintaining the proper functionality of the electrical connector during cold weather both before and after the electrical charging activity.
[0040] The present invention has been described above with reference to a number of exemplary embodiments as shown in the drawings. Modifications and alternative implementations of some parts or elements are possible, and are included in the scope of protection as defined in the appended claims.
