Description

Mobile Solar Powerplant
The present invention is mobile solar plant, i.e. an apparatus for generation of electrical energy from photovoltaic cells based on a mobile vehicle, thus called the Mobile solar powerplant. The Mobile solar powerplant consists of the electrical system installed on the mobile vehicle base, which can be any road-worthy vehicle that can be towed by another vehicle or move independently, either powerless or with independent means of locomotion. While methods for mobile power generation based on the photovoltaic principle exist, UN 7795837 (Bl), US 2010212659 (Al), US 6380481 (Bl) US 5969501 (A) they all focus on a device used for production of electrical energy, which is installed on a moving towable vehicle. The present invention however represents an upgrade of an existing towable vehicle in such manner, that the existing vehicle retains the capability of housing another vehicle , i.e. aircraft, land-based or maritime vehicle, which can receive charge from the electrical system of the present invention. The present invention removes the neccesity of one vehicle towing the trailer, which houses the aircraft, land-based or maritime vehicle to be charged, and another vehicle which would have the role of providing electrical energy via the photovoltaic principle and combines these functions in one vehicle. Furthermore, besides providing charging energy to the aircraft, land-based or maritime vehicle, which is being housed inside the vehicle base, the present invention can provide power to other electrical appliances via standardised electrical outlets. Also, as a contrast to above mentioned recognised inventions, the Mobile Solar Plant can function both during driving and when stationary and is not subject to use only when stationary and arranged for operation. All elements of the electrical system of the Mobile Solar Plant are fixed and do not need to be repositioned for their function. The components are small and lightweight, in contrast to UN 7795837 (Bl), US 2010212659 (Al), US 6380481 (Bl) US 5969501 (A), and can be installed anywhere on the vehicle using
standardised brackets and fastening elements.
Primarily, the Mobile solar powerplant is designed to transport and provide means of mobile standalone charging to an electric-powered aeroplane, but its scope also stretches to use with land- based, maritime or other vehicles and also in vehicle-free operation as a stand alone mobile powerplant, providing power to electrical appliances of DC and AC kind. The Mobile Solar
Powerplant's electrical system comprises small and lightweight elements, which permit for an installation of the system to an existing, non-dedicated towable vehicle. Because of this the capacity of housing of another vehicle on-board the towable vehicle is retained. The Mobile solar powerplant can operate either stationary or while moving. The electrical system provides for conversion of solar energy derived via photovoltaic cells into useful DC and AC circuits for connection of any electrical appliance, functioning together with the base vehicle or as an independent solar powerplant with energy storage.
The invention will be described by the figures showing:
Figure 1 - Mobile solar powerplant representation,
Figure 2 - electrical system schematic.
Any mobile vehicle can be used as a base to the electrical system. The electrical system consists of photovoltaic cells 1 either mounted directly onto vehicle base structure or in the form of panels installed anywhere on the vehicle, DC-DC power converter 2 converting the power generated by the photovoltaic cells to usable, e.g. 12 V or 24 V DC voltage, DC-AC inverter 3 converting the DC voltage to usable AC voltage, e.g. 110 VAC, 240 VAC, etc., a buffer battery 4 of any electrical energy storage principle for temporary electrical energy storage, the bypass switch 5, buffer battery charger 6, electrical inlets 7, electrical outlets 8 and wiring 9, safety elements 10 and climate control fan/heater assembly 11. Optional is a diagnostics/monitoring system 11. The schematic of the electrical system of Mobile solar powerplant is shown in Figure 2. The components are small and lightweight, in contrast to UN 7795837 (Bl), US 2010212659 (Al), US 6380481 (Bl) US 5969501 (A)
The photovoltaic cells 1 gather the energy from solar radiation and power the DC-DC power converter 2. The number of photovoltaic cells is arbitrary and depends on the desired power capability of the system. Connections of the photovoltaic cells 1 to the DC-DC power converter 2 depend on its characteristics, however in principle both serial and paralell as well as hybrid wiring configurations are covered.
The DC-DC power converter 2 receives power from the photovoltaic cells 1 and converts it to usable DC voltage, while providing for protection properties to the photovoltaic cells 1. Use of multiple DC-DC converters in serial, parallel or hybrid configurations is covered by wording »DC-DC power converter«. The DC-DC power converter 2 can take advantage of of all electronic, electromechanic,
electromagnetic or other principles to achieve its function. Output of the DC-DC power converter 2 is a stabilised DC voltage, which can be utilised by widespread appliances requring DC voltage i.e. 12V, 24V or other for its function.
The DC-AC inverter 3 converts the DC voltage to AC of desired voltage and frequency. Use of multiple DC-AC inverters in serial, parallel or hybrid configurations is covered by wording »DC-AC inverter«. The DC-AC inverter 3 can take advantage of all electronic, electromechanic, electromagnetic or other principles to achieve its function. Output of the DC-AC inverter 3 is stabilised AC electrical power, which can be utilised by widespread appliances requring AC voltage i.e. 110 VAC 60 Hz, 240 VAC 50 Hz or other for its function.
The buffer battery 4 is charged by the buffer battery charger 6. The buffer battery 4 can use any principle of storing electrical energy for shorter or longer periods of time. The properties of the battery follow desired power and storage characeristics of the system. The battery charger provides means of delivering electrical power to the buffer battery 4 in order to achieve long-term or electrical energy storage.
Bypass switch 5 provides the capability of connecting the Mobile solar powerplant to an electrical network in case its function of delivering power from photovoltaic cells is not desired or otherwise hindered. When the Mobile solar powerplant is connected to the electrical network, the capability of charging the buffer battery 4 is retained, as is the ability of the Mobile solar powerplant electrical outlets 8 to provide useful DC and AC electrical power. When activated, the bypass switch 5 disconnects photovoltaic cells 1 and DC-DC power controller 2 from the system.
There can be one or more electrical inlets 7 installed anywhere on the Mobile solar powerplant. The electrical inlets 7 are used to connect the Mobile solar powerplant to the electrical network when its function of delivering power from photovoltaic cells is not desired or otherwise hindered. The inlets can be of various shape, style and form, but can accept regular established electrical network/cable elements.
There can be one or more electrical outlets 8 on/inside the Mobile solar powerplant, delivering useful DC and AC power to be used for powering electrical appliances, including chargers of electrical vehicles being housed in the Mobile solar powerplant. The inlets can be of various shape, style and form, but can accept regular established electrical network/cable elements.
The wiring and safety elements 9 connect all components electrically. The safety elements 9 include but are not limited to circuit breakers, fuses, power relay, signal checks, diagnostics systems and other support elements.
The climate control fan/heater assembly 10 regulates the temperature inside the Mobile solar powerplant, should this be important for the vehicle stored inside the Mobile solar powerplant. The fan/heater assembly 10 uses electrical energy to heat and/or cool the interior of the Mobile solar powerplant by inducing thermal emmisions and providing for a steady flow of air through the Mobile solar powerplant. Its mounting location can be anywhere on the Mobile solar powerplant. The diagnostics/monitoring system 11 is the apparatus that gathers information from individual system components and displays it to the user. It can consist of a screen, diagostics connector or other means, including wireless signal connections, of delivering information about the system to the user. Its mounting location can be anywhere on the Mobile solar powerplant.
