Description

LOCAL ELECTRICAL POWER STATION Background of the Invention

In the near future Electric Vehicles (EV) may become the main means of transportation, as various vehicles are being manufactured with an electric battery, e.g. Electric Cars (EC), Electric Motorcycles (EM) and Electric Bicycles (EB).

Several systems have been proposed, aimed at shortening the charging time of an electric vehicle's battery, although these systems require a large amount of high DC electrical power, i.e. high voltage, high direct current (DC), approximately 25-150 kilowatt per hour (kWh) and higher. Presently the electricity is typically consumed with low efficiency from long distance AC supply electrical networks, supplied from distant power plants with low efficiency and several times conversion of high voltage to low voltage transference through several relay stations and transformers, with harmful electro-magnetic radiation to the environment and which produce electricity from, among others: fuels, oil, coal, gas and carbon.

Several systems such as solar carports and some tower based parking facilities suggest utilizing solar energy for charging EVs, although these systems generally fail to provide sufficient rates of electricity with high efficiency and high energy for charging an EV battery, at the same time, in a short time. Moreover, tower based parking facilities, such as for example those disclosed in CN205677318U, CN205677319U, CN205502656U, JP5156583, and JP2012046997, have another major drawback as they are lack the ability to continuously charge or discharge multiple EVs without cession, and thereby they are unable to be used as an actual power source core for the implementation of an autonomous_electrical charging or discharging(at least partly) or exchange power station hereinafter; local electrical power station.

Moreover, a typical battery of an EV is capable of storing or accumulating and discharging relatively high rates of energy, in terms of electricity. While a non-plug- in hybrid EV comprises a battery with capacity of a few single kWh, full-electric EVs comprise batteries with capacity of up to -250 kWh and more for each individual channel (as of the date of the present patent application). This obviously describes a strong and available source of energy for everyday electricity consumers. For sake of comparison, a typical apartment consumes an average of ~2-5kWh (day use), when considering both AC and DC electrical power. It would be immensely advantageous to have a system capable of utilizing the electric power stored or accumulated or exchange on batteries of cluster EVs, EMs, EBs to supply power to DC electrical power consuming devices, domestic appliances, apartments, buildings, etc.

Evacuate one or more pathways from parked vehicles, in particular vehicles that remain in the streets without daily uses (especially in periphery cities parking facility), into robotic parking power station, and thereby creating a pathway designated for electric bicycle, cycling, or public transportation (bus, train, shared vehicle, etc.), reducing the use of vehicles and creates beyond the safe use and economical.

Accordingly, it is an object of the present invention to provide a system which is capable of utilizing energy stored in parked vehicles for continuously charging and discharging other electric vehicles or other DC consumers.

It is therefore another object of the present invention to provide a local autonomous power station capable of continuously providing high DC solar or PV-based, electrical power to EV batteries and to other local DC electricity consumers in an urban or other domestic environment, such as a single building, or a plurality of buildings, apartment's domestic appliances_^

Today, many domestic appliances and other consumers in the apartment, convert AC voltage power to low DC voltage. It is yet another object of the present invention, to provide a new local DC voltage electric grid that will enable users to easily switch from AC source usage to only DC voltage while eliminating the need to convert AC to DC, so that all appliances, consumers and users will change the electric motors, heating elements, air condition compressors to work from the new DC voltage network. It is another object of the invention to provide an electric power station capable of continuously providing high DC electrical power from one or more EV batteries and from other electricity accumulators to DC electricity consumers.

It is yet another object of the present invention to use batteries of electric vehicles (EVs) as "electricity generators", "conductors" and "power suppliers", as a substitute for cables and transformers on electricity poles pylons of existing electricity grid.

Presently many streets are designed so that approximately the equivalent width of a driving lane is reserved on each side of the road for parking spaces. It would be advantageous to save this street area while maintaining a standard amount of roadside parking spaces and allowing other uses of the spared roadside area. It is therefore another object of the invention to spare roadside parking space area and provide alternative parking spaces, the number of which is equal or larger than the spared roadside parking spaces by providing novel parking facilities that are capable of charging/discharging EV without cessation (i.e., as long as the EV is located within the parking facility and connected to a charging or discharging port), wherein the parking facilities may include rotary & robotic layers-based parking facilities, and various PV solar panels above buildings, streets and junctions.

Moreover, it is common to have storage boxes, rooms, and parking areas located beneath buildings, houses and on the ground floor thereof. It would be advantageous to spare this building area. It is therefore still another object of the present invention to spare storage and parking areas within building allowing other uses of the spared building area by utilizing regions in the novel parking facilities as alternative storerooms for bicycles, motorcycle, merchandise and equipment.

Other objects and advantages of this invention will become apparent as the description proceeds.

Detailed Description of the Invention

The present invention describes a stand-alone local electrical power station adapted to obtain electrical DC power from solar panels such as Photovoltaic Cells (CPV), Concentrator Photovoltaic Cells (CPVC), High-Concentrator Photovoltaic Cells (HCPVC) and High-Concentration Photovoltaic Thermal Cells (HCPVTC) (collectively solar panels) and other alternative renewable energy sources, such as wind (e.g., wind turbine), seaweed, sea waves energy, etc. In addition, electrical power is obtained and received from one or more batteries of one or more Electric Vehicles (EVs). The local electrical power station is capable of providing, without cessation, electrical DC power to several power consumers, such as batteries of EVs (including Electrical Cars (EC), Electric Motorcycles (EM), Electric Bicycles (EB), electrical powered wheelchairs, etc.) Residential, commercial buildings, instruments and domestic appliances which consume and will use DC electricity (e.g. domestic or public LED light fixtures, computers, battery chargers, and oven, Air conditions, refrigerator etc.) via DC electric Locally grid and DC electrical outlet, as is known in the art.

The local electrical power station comprises a rotative robotic parking facility in which EVs (e.g., ECs, EMs, EBs) can be parked and be electrically connected via one of a plurality of parking cabins that are part of the rotative robotic parking facility and as will be described in further details hereinafter. The electrical connection between EVs (such as ECs, Ems and EBs) and the robotic parking facility is appropriate for charging the batteries of the EVs parked in the robotic parking facility, and to discharge electricity accumulated in the batteries of the EVs (e.g., the energy of a charged battery of an EC can be discharged (e.g. 10%-50%)/exchange and used for charging an EM, EB and an electrical powered wheelchairs).

Fig. 1 schematically illustrates an upright rotative robotic parking facility 100, according to an embodiment of the invention. Parking facility 100 comprises plurality of cabins 102, each cabin 102 may include one or more charging or discharging or exchange ports (e.g., as indicated by numeral 108 in Figs. 10 and 11). Cabins 102 are capable of accommodating EVs and charging or discharging the EVs without cessation (as long as an EV remains electrically connected to the charging or discharging port). Furthermore, each of the cabins 102 comprises sufficient space for accommodating a plurality of EVs, i.e. an EC, one or more EMs and/or one or more EBs, all in one cabin. According to some embodiments, in addition to their charging or discharging capabilities, cabins 102 can also be used as a storage unit, e.g., an alternative storeroom for storing personal stuff such as ski equipment.

In this embodiment, each parking cabin 102 is connected to a chain conveyor 104 (e.g., through tubed axis located along the side or top of each cabin 102, and which on its edge connected bearing to multi arms chain conveyor 104). Conveyor 104 consequently shifts the cabins 102 from one position along the robotic parking facility 100 to another position as to allow EVs to enter or exit the parking facility 100 (e.g., at a ground level entry point). In this embodiment, conveyor 104 has an elliptic form. An elliptic guide track rail carrier 200 is installed in parallel to conveyor 104. Conveyor 104 is capable of rotating both clockwise and counterclockwise. In this embodiment, the circular motion is bidirectional. Conveyor 104 can be attached to the frame 112 of the main structure of parking facility 100.

In this embodiment, guide track rail carrier 200 comprises an isolated electrical rail busbar 201 (see Figs. 2A, 2B, 2C and 2D), which is made of metal conductors (e.g., copper or brass) and deployed in an elliptic manner along the structure of the guide track rail carrier 200. Busbar 201 configured to concentrate and distribute electrical power throughout parking facility 100. Busbar 201 is adapted to transfer high voltage Direct Current (DC), via a slidable multi-axial connector 202 (see Figs. 2A- 2D), from and to parking facility 100 and in particular from and to the charging or discharging port of cabin 102.

A shown with respect to Figs. 2A-2D, Multi-axial connector 202 is a novel electric multi-connector that combines an electric rotary slips rings 204 (e.g., SR004 series electric slip ring by Rotary Systems, Inc.) with a plurality of graphite brush conductors 203 that are electrically connected to the rotating elements of the electric rotary slips rings (each graphite brush conductor 203 is connected to a different rotating element or ring of slips rings 204). Each graphite brush conductor 203 is adapted to contact and slide on a corresponding metal conductor of busbar 201. For example, connector 202 may include five (or more) graphite brush conductors 203, such that each graphite brush conductor 203 contacts a specific metal conductor on busbar 201, and through which high voltage DC is being transferred to the electric rotary slips rings.

In a charging mode, multi-axial connector 202 transfers the total high voltage DC received from all the graphite brush conductors 203 to the charging port in cabin 102. In a discharging mode, multi-axial connector 202 splits and transfers high voltage DC received from a charged battery (e.g., of an EV) to busbar 201 via the graphite brush conductors 203. In this embodiment, the graphite brush conductors 203 are located on the housing of the electric rotary slip ring 204 (as best shown in Fig. 2D). As schematically illustrated in these figures, the graphite brush conductors 203 are installed on top of the housing of slip ring 204. This novel and unique structure enables continuous distribution of bidirectional electricity throughout parking facility 100 in order to charge or discharge EVs or other DC consumers without cession, during the rotation of multi- arms chain conveyor 104 and as well as when the multi- arms chain conveyor 104 at rest. The connection between parking cabins 102 and multi-arms chain conveyer 104 is comprised of a physical connections and an electrical connection through busbar track rail 201. The electricity supplied through the electric conductors of busbar track rail 201 is in the form of Direct Current (DC) which is the form of electricity consumed, accumulated, or distributed (e.g., between EC, EM, EB in cabin 102 or with other cabins in the parking facility 100 by EV batteries) or other accumulating storage in parking facility 100.

The uprightness of parking facility 100 provides several advantages over ordinary vertical parking facility, as it enables a continuous charging or discharging or exchange of EVs. Moreover, it provides rental or taxi station, bonded warehouse, economy mobility from vehicles to refueling stations and huge multi accumulators on which parking facility 100 is built; and safe guarding and video camera survey - parking in an elevated position requires a user to perform a predefined action, such as enter a code (e.g., via a control panel or a mobile phone application), in order to bring a parking vehicle to ground level and retrieve or return the vehicle. Parking facility 100, in particular each of cabins 102, includes data communication means, as to enable to communicate and to remotely control the operation of parking facility 100 and cabins 102 , e.g., via a router (Wi-Fi or any other wireless or bi-direction data communications).

As described hereinabove, Figs. 2A-2D schematically illustrates a detailed view of the elements of the guide track rail carrier 200 and the multi-axial connector 202, according to an embodiment of the invention. Guide track rail carrier 200 comprises the busbar track rail 201 on which the multi-axial connector 202 slides (when shifting the cabins 102 from one position along the robotic parking facility 100 to another position). As aforementioned, busbar 201 is provided in an elliptical formation that corresponds to form of guide track rail carrier 200. The elliptical form of the metal track rail conductors of busbar 201 adapted to transfer high -voltage DC and may include several metal conductors each of which is capable of transferring appropriately voltage capacity (e.g., in these figures the busbar include five copper conductors that each bar may transfer around ~1000 volt DC supplied from various sources and ~250 ampere and more for each individual channel (e.g., MPVP - Multi HCPVT (High Concentrated Photovoltaic Thermal), CPV, PV Panels, and other alternative renewable energy sources, so that for applications that may require higher voltage - more metal conductor can be used).

Multi-axial connector 202 consists of plurality of connectors and may include the following:

An electric rotary slip rings connector 204 (e.g., SR004 series electric slip ring by Rotary Systems, Inc.).

- Metal (e.g., copper or brass) & graphite brush 203 that are adapted to slide on the conductors of busbar 201 and which are connected to the interior moving parts of rotary slip ring 204 (e.g., in the SR004 model through electric cables entry conduit fitting 205 for conducting current between the cables and the moving parts).

Conduit fitting 205 are used as a pathway for delivering high voltage DC & signal data.

In this embodiment, rotary electric slip rings connector 204 located below carbon brush conductors 203 in a way that its rear side faces the conductors of busbar 201 and its front side faces cabin its associated cabin 102 and it is connected to the central shaft 210 of this cabin. Rotary multi slip rings 204 continually provide high volt DC via multi-electric (i.e. copper, brass, metal leaf, touching circle copper) connectors (e.g., may include five or more connectors high voltage & low data connectors).

High voltage DC electric cable (multi electric wires) entry into conduit fitting. - An anti-rotation bracket 206 (e.g., an integral part of rotary slip rings connector 204) is used to hold the metal (e.g., copper or brass) & graphite brush 203 through elliptic guide track rail carrier 200.Brackect 206 is connected to the metal cover housing of rotary electric slip rings connector 204 (bracket mounting).

With respect to cabin 102, cabin 102 is connected through High voltage DC electric & data cable may deploy through main cabin shaft 210 consist main cabin tube shaft 210 connected to a fixing flange between rotary E- multi slip rings connector 204 to the plurality graphite brush sliding connectors 203 to the electric busbar track rail 201 to high voltage DC electric & data cable may deploy through conduit fittings high Voltas DC & data signals connected to electric insulated cables guide track rail carrier 200.

Electrical busbar track rail conductors 201 mounted on the elhptical guide track rail carrier 200, connected to the main metal frame structure of parking facility 100. In this embodiment, above each cabin 102, there is an axis holder (a mechanical axis). One end of the mechanical axis comprises the multi-axial electric connector 202 that is connected on one side of the axis holder and on another side to the busbar 201. The electrical connection between connector 202 and a cabin 102 comprises one or more wires that passes through a hole (drilled) in a bearing shaft center into the electric connector 202 (e.g., comprising brush graphite and rotary copper conductors), thereby allowing to establish electrical connection without cessation even during bi-directions rotations due to connector's 202 ability to rotate along the multi axis. The busbar side of connector 202 comprises sliding surfaces comprised of graphite, copper or other material conductors 203, each conductor 203 engaging or brushing a conductor on the busbar 201 and transferring electricity from the busbar 201 to connector 202 that is connected physically and electrically to the axis holder. The continuous connection between EVs and the busbar 201 via connector 202 allows continuous charging and discharging through connector 202 at all times an EV in a cabin 102 is connected, via the holder axis, to connector 202.

According to an embodiment of the invention, PV & solar panels (PVC, CPVC, HCPVC and/or HCPVTC) are positioned in the proximity of robotic parking facility 100.

Fig. 3 schematically illustrates a plurality of multi HCPVT 109, CPV, PV & solar panels (which are generally indicated by numeral 106) attached to the exterior walls and top of parking facility 100, also nearby parking facility 100 position other alternative renewable energy sources.

According to an embodiment of the invention, parking facility 100 may further comprise an automatic car washing machine 110 (see Figs. 1, 2, 13 and 14) that is powered by DC electricity originating from the EPS electricity sources (i.e. EV batteries and solar panels). Car washing machine 110 may automatically load an EV that is parked in cabin 102. For example, washing machine 110 may include a mechanism for automatically retrieving a vehicle from cabin 102 of parking facility 100, and transferring it through an automated washing process within washing machine 110. Upon completing the washing process the vehicle is automatically returned into cabin 102 of parking facility 100. Alternatively, car wash can be performed in the cabin during parking charging or discharge or exchange electric energy.

In addition, parking facility 100 includes a managing system (e.g., that can be located at the entrance to parking facility 100) for managing the usages and services applied to each parking vehicle, such as billing, payments, and balancing between meters (e.g., between a charging mode a discharging mode or an exchange mode).

Figs. 4-7 schematically illustrate an exemplary scenarios of an autonomous local - electric power station and energy management center for apartments, buildings that includes multiple charging, discharging and accumulating continually and without cessation EVs, EMs, EBs, multiple HCPVT, CPV, PV vertical, horizontal multiple parking cabins, (with boxes or cells storages), and an optional arrangement for suppling hot water to various consumers with meters management systems. All cabins described above, installed with communications system via router (Wi-Fi or any other wireless or bi-direction data communications).

Fig. 4 shows PV solar panels 107 attached to buildings near parking facility 100. The electrical power produced from the PV solar panels 107, and CPV panels 106 is transferred to the parking facility 100 by electric wires through (not shown in the figures). In addition, the system may include one or more HCPVT units 109 capable of providing electric power and simultaneously transferring hot water for domestic (e.g., residential buildings) or commercial usage, (e.g., producing electricity from steam electric turbine circulation) as further described with respect to Fig. 12.

The solar panels 106, 107, 109, 114 can be one or more units of Photovoltaic Cells (PVC), Concentrator Photovoltaic Cells (CPVC), High-Concentrator Photovoltaic Cells (HCPVC) and High-Concentration Photovoltaic Thermal Cells (HCPVTC).

Electrical DC power is obtained by the local electrical power station from the PV & solar panels and from nearby other alternative renewable energy sources and from batteries of EVs in the robotic parking facility 100. The electrical DC power can be used for uses other than charging batteries of EVs parking in the robotic parking facility 100, such as supplying electricity to DC powered devices in houses or buildings, apartments or streets near the local electrical power station via local novel DC electricity grid of the invention. The buildings and houses can also comprise PV & solar panels on their exterior walls and roof, different types of sunshade, over pedestrian walkway and cars, EVs parked on the street (e.g., as shown in Fig. 4), thereby allowing wider consumption of solar energy for the purpose of electricity production.

Fig. 5 schematically illustrates solar panels 107 located in different locations. Solar PV Panels 107 can be on roofs of houses or on roofs of buildings or in various places associated with the local electrical power station, such as above streets or between and above trees. The PV & solar panels are connected to an apparatus (e.g. a heliostat sun tracker) for adjusting the orientation of the panels in order to absorb sunlight optimally, as is well known in the art. According to another embodiment of the invention panels can be positioned throughout public space, e.g. on flexible poles attached to unnatural trees or natural trees located aside a street.

For example, Fig 9 schematically illustrates a rotative robotic parking facility combined with synthetic or natural plants as indicated by numeral 901, synthetic trees are connected to an apparatus (e.g. a heliostat) for adjusting the orientation of the panels in order to absorb sunlight optimally, as is well known in the art. According to another embodiment of the invention panels can be positioned throughout public space, e.g. on flexible or rigid poles attached to unnatural trees and from other alternative renewable energy sources.

According to an embodiment of the invention, while the PV & solar panels produce electricity, i.e. during daylight hours, EVs connected to the local-electric power station can be charged from the solar panels. At times that the PV & solar panels don't produce electricity, i.e. at night or in cloudy weather, the EV batteries or from nearby local-electric power station and from emergency batteries accumulators and from other alternative renewable energy sources (e.g. wind, seaweed, sea waves energy, etc.), discharge energy to other consumers that are connected to the local electrical power station and simultaneously exchange electric energy in-between consumers and local accumulators suppliers.
