2kw to 20kw Hybrid Power Systems for Recreational and Special Vehicles
2019100177 17 Feb 2019
Abstract
This innovation relates to electrical power systems in recreational and special vehicles that do not use electrical power exclusively for locomotion. When stationary, if energy demand is greater than 2-3kw, an independent electrical generator or site power may be required to meet this energy demand. This innovation introduces in-vehicle power generation greater than 2kw used in conjunction with renewable power sources to charge Lithium Batteries on an independent subsidiary electrical system at 48VDC with conversion to 12VDC/24VDC network of appliances and energy consumers on an independent network with a battery (ies) and with conversion to 110-240V A/C network of appliances and energy consumers .
Background.
Vehicles powered by fossil fuel for locomotion are available with the utility of accommodation, cooking, living, office and bathroom facilities. This utility is either in the body of the vehicle or in a directly towed caravan or trailer. They are also available with or without the aforementioned utility with emergency functions, ambulance function, law enforcement functions, communications functions, firefighting and protection functions, aircraft support functions, healthcare functions, community services functions, agricultural support service functions and similar base operating Stationary Functions when not in locomotion. Collectively vehicles with these functions and utility are called Recreational and Special Vehicles (RSV) in this Specification.
RSV require electrical power to serve the functions described in the paragraph above. Electrical power is the instantaneous measurement of voltage and current flow following the equation of Power= V (Volts) x I (Current). Current may be either alternating current (A/C) with a alternating phase sinusoidal curve or direct current (DC). Electrical energy is the integration of the instantaneous power overtime. When electrical power is measured in SI units of watt, electrical energy may be measured in watt hours.

2019100177 17 Feb 2019
Batteries store electrical energy up to the limit of their rated capacity. The rated capacity of a battery is a function of the battery chemistry of charged material type and the volume of charged material. Different material types have varying density of stored energy when fully charged. Lithium ion (called just Li is this specification) describes a range of battery chemistries that all have lithium and may have one or more of other elements or their derivatives that combine to form charged material. Li has superior charging efficiency and greater electrical energy storage density than lead/acid based batteries. This makes Li superior for charging and discharging with little energy loss converting charged material to and from electrical power. Batteries deliver electrical power only as Direct Current (DC). An inverter may be used to convert this Direct Current power to Alternating Current (A/C) power. A battery charger may be used to transfer electrical Direct Current power to charged material stored in the battery. An inverter/charger is a device that serves both these functions but not simultaneously.
RSV may require electrical power to operate refrigeration, air-conditioning, heating, lighting, communication, water pumps, computers, cooking, broadcast communication, opening and closing functions and other functions that require electrical power to complete that function.
Power generators of renewable electrical power are photovoltaic panels (called “solar” in this specification) and wind generators. Renewable energy generators may be stored on-board the Special vehicle and may be operated when the Special vehicle is either in locomotion or stationary. Solar power output scales with the efficiency of the Photovoltaic cells, the area of exposure to the sun at the incidence angle to the sun and the sun’s intensity. For RSV, a typical PV system on a large 7m x 2m free roof area can not produce more than 2kw power at peak efficiency and direct 90degree angle on incidence to the sun. This occurs for a short period of time with PV power output ranging from close to zero at sunrise to peak power and back to close to zero at sunset. The sun’s intensity cannot be guaranteed and this form of renewable energy can not be relied on as a consistent power source.
Fossil fuel power sources that convert fossil fuel to electrical energy may include mobile A/C or DC generators, Fuel Cell generators may use Methanol or LPG.
2kw to 20kw Hybrid Power Systems for Recreational and Special Vehicles
2019100177 17 Feb 2019
Collectively these are referred to as “fossil fuel generators” in this specification.
These fossil fuel generators may operate independently to the RSV’s propulsion engine. These fossil fuel generators may be stored on-board the RSV and may be operated when the RSV is either in locomotion or stationary.
Methanol and LPG Fuel Cell power generation may be limited to less than 1 kw.
A/C and DC Power generator choice for a RSV may be constrained by volumetric space, weight, access, fuel availability and /or noise restrictions on use.
RSV may use a 12V or 24V direct current electrical system to start and operate the engine and ancillary systems needed for locomotion. To preserve the electrical energy available for these systems, a dedicated engine battery system may be used. This system may be charged from the RSV engine using an alternator and/or it may be charged from other generator sources.
RSV have a separate 12V / 24V DC electrical system to provide power to appliances and electrical devices that may be connected. Other appliances and electrical devices may be connected to a 220-240V A/C electrical system. This may be compatible with the Australian electrical grid power supply to consumers.
Solar power generation has a limit of the power capacity installed on the RSV joined by additional mobile or portable systems carried with the RSV and the time of day, sun’s incidence angle to the solar system and the sun’s intensity. These factors collectively place the solar power as an unreliable power source. In perfect conditions, the solar power is unlikely to exceed 2kW because of the physical size of solar systems needed to support this power level.
RSV may have a power demand greater than the available power source or sources for a given period of time. This difference in power demand less power supply is filled by drawing power from the batteries over time. This power over time is the electrical energy consumed. If the electrical energy consumed exceeds the available stored energy in the batteries, electrical power may fail. Failure of the electrical power supply may have significant inconvenience and even safety impact to users
2kw to 20kw Hybrid Power Systems for Recreational and Special Vehicles
2019100177 17 Feb 2019 who may be dependent on electrical power for cooking, heating, cooling and other functions that are more than comfort.
RSV may therefore require deployment of additional power sources to be used in combination with on-board power sources to collectively have the capacity to provide sufficient electrical energy to meet the collective electrical energy demand over a given period of time. These additional power sources may not be able to be deployed all the time. This may be because of a requirement for the Special Vehicle to be available to move to a new location at short notice for operational or safety reasons. It may also be because there is a noise level restriction which prevents power generation from sources that create a specified noise level. It may also be because the A/c or DC generator fuel has been consumed in full with no more available on the RSV at that location.
In such circumstances, curtailment and/or failure ofthe electrical power supply may have significant inconvenience and even safety impact to users who may be dependent on electrical power for cooking, heating, cooling and other functions that are more than comfort.
Related Material
A current method used to increase the electrical energy available by increasing the battery capacity to accommodate the forecast electrical energy shortfall. The difficulty is to have sufficient power charging sources to replenish the forecast energy consumed in a given period of time. Without sufficient replenishment electrical energy, the finite battery storage capacity will ultimately become insufficient to operate the RSV stationary functions.
Another current method used is to operate additional A/C and DC generators adjacent to the RSV or in spaces that are accessible from the exterior of the RSV. These may be started remotely and may have their own independent fuel supply. These A/C and DC generators may have restrictions on time of use because of noise, or emitted carbon restrictions in certain geographical locations or there may be restrictions on use because of immediate locomotion ofthe RSV, or they may be insufficient fuel remaining for the additional A/c or DC generators.

  4. 4), and/or 240V A/C appliances and electrical devices and does not require external access nor create increased noticeable noise and can replenish increased electrical energy demand by operating the propulsion engine (
  5. 5) in the RSV.
    Description of Claims
    The system in accordance with this invention comprises a 48VDC generator driven from either the engine directly or from the PTO shaft directly or indirectly and capable of greater than 2kw output. This provides power to charge 48VDC battery(ies) which may be Li. If PV solar is a power source, it may convert to the 48vDC level to the battery(ies). If 240V A/C power is available at any time, it may convert to the 48VDC battery(ies). There will be a 48VDC converter to either 24VDC or 12VDC for direct current connected devices on a 24VDC and/or 12VDC electrical circuit. A 124VDC and/or 12VDC battery(ies) may be added to this circuit. There may be a 240V A/C Inverter that converts the 48VDC electrical energy to 240V A/C. The 48V DC battery(ies) may comprise a combination of 12V DC battery(ies) in series or 24VDC battery(ies) in series.
    This invention has been specially devised to give peace of mind for users of RSV that energy demand greater than 2kW can be met. The length of time that this can be met is dependent on the size of the various battery systems and the time of use of the DC Generator attached to the RSV engine. This invention gives convenience of use and may be available in any geographic location at any time of the day.
