Field of the Invention
This invention relates generally to power systems and, more particularly, to a mobile, self contained electrical power generation and storage system.
Description of the Prior Art
In today's society, many of the most basic daily functions require access to electrical power. Society's ability to provide electrical power from fixed, centralized sources through a traditional electrical grid has continued to develop and evolve in such a manner that in many industrialized nations, constant and ongoing access to electricity is taken for granted under normal conditions. As a result, whenever electrical power is lost, most operations of individuals and of society as a whole tend to come to a halt.
To address the issues created by our extreme reliance on ongoing electrical power, many forms of mobile power generators have been developed for supplying power locally in the event that power from the electrical grid is lost. A problem which still exists, however, is that known mobile power generators are typically tied solely to access to non-renewable resources, such as gasoline, and do not integrate or otherwise make use of both renewable and non-renewable resources. Thus, there remains a need for a portable power station system which incorporates both renewable and non-renewable resources to maximize its electricity generation and storage capabilities. It would be helpful if such a portable power station system was able to provide power in both AC and DC. It would be additionally desirable for such a portable power station system was additionally capable of providing mechanical energy.
The Applicant's invention described herein provides for a power generation system adapted to provide electrical and mechanical power from a mobile assembly. The primary components of Applicant's portable power station system are renewable power generators, batteries/super capacitors, an inverter, an AC motor, a brushless DC motor, and an alternator. When in operation, the portable power station system allows a user to access both AC and DC electrical power generated through a plurality of types of generators. As a result, many of the limitations imposed by prior art power stations are removed.
A portable power station system for providing access to electrical power and mechanical energy in from stored and renewable sources, such as solar and wind. The portable power station system comprises a housing containing a battery, a brushless DC motor, an inverter, a gear system, an AC motor, an alternator, a rectifier, a reservoir capacitor, a charge controller, sequentially connected with the charge controller connected back to the battery. Solar panels and a wind power generator are additionally connected to the charge controller to provide an input of electrical energy. A plurality of grounds are also provided.
In operation, the components of the portable power station system convert stored energy from the battery into other forms of energy and provide access to the various forms of energy through various discrete outputs accessible from the exterior of the housing. To account for the losses that inevitably occur during such conversion and which result from the user accessible outputs, the portable power station system utilizes renewable forms of energy to continually introduce additional energy.
It is an object of this invention to provide a portable power station system which incorporates both renewable and non-renewable resources to maximize its electricity generation and storage capabilities.
It is another object of this invention to provide a portable power station system which is able to provide power in both AC and DC.
It is yet another object of this invention to provide a portable power station system that is additionally capable of providing mechanical energy.
These and other objects will be apparent to one of skill in the art.
Referring now to the drawings and in particular
The brushless DC motor 12 receives the DC electrical energy and uses it to supply mechanical energy to a mechanical system 16, defined in the as a series of gears. In an alternate embodiment, a series of pulleys can be used in the mechanical system 16.
The inverter 12 receives the DC electrical energy, converts it to alternating current (AC) electrical energy, and supplies the AC electrical energy to an AC motor 14. The AC motor 14 uses said AC electrical energy to supply mechanical energy to the mechanical system 16 and to an AC power output connector 13a. It is contemplated that a user of the portable power station system 10 can selectively activate or deactivate the brushless DC motor 12 or the AC motor 14 so as to have either or both running at a given time.
The DC power output connector 11a is configured to provide DC electrical energy from the battery 11 and supply it to an electrical outlet accessible from the exterior of the portable power station system 10 housing so as to allow a user to supply such DC electrical energy to an external device by connecting the external device to the DC power output connector 11a. The AC power output connector 13a is configured to provide AC electrical energy from to an electrical outlet accessible from the exterior of the portable power station system 10 housing so as to allow a user to supply such AC electrical energy to an external device by connecting the external device to the AC power output connector 13a
The mechanical system 16 operates as a conventional gear or pulley system, in concert with a mechanical output attachment 16a, to take the mechanical energy provided to it and act to change the speed, torque, or direction of the energy in a desired manner. It is contemplated that a plurality of differing compatible mechanical output attachments 16a can be adapted to dock with the mechanical system 16 and change the speed, torque, or direction of the gear movement. In one embodiment, the mechanical output attachment 16a is defined as a larger compatible gear system which increases the torque of the mechanical system 16 movement. In other embodiments, the mechanical output attachment 16a is defined as a rack system which increases changes the rotation movement of the mechanical system 16 from rotation to translation. The mechanical output attachment 16a can then be mechanically connected to another device which desires produced mechanical energy.
The mechanical system 16 also provides mechanical energy to an alternator 18, defined as an AC electric generator. The alternator 18 coverts mechanical energy from the mechanical system 16 to AC electrical energy. This AC electrical energy is supplied to a rectifier 19, where it is converted to DC electrical energy, and then to a reservoir capacitor 20, to produce steady DC electrical energy from a rectified AC electrical energy supply. This DC electrical energy is then routed from the reservoir capacitor 20 a charge controller mechanism 21 which controls the charging of the battery 11 so as to assist in recharging the battery 11.
In one embodiment, the charge controller mechanism 21, is defined by a plurality of discrete charge controllers, each of which is connected to a supply of DC electrical energy. As such, the charge controller mechanism 21 is additionally connected to a solar power generator 22, defined as a solar panel and a wind power generator 23. The electrical energy generated from the alternator 18, solar power generator 22, and the wind power generator 23 is used to recharge the battery 11. In some embodiments, the solar power generator 22 is used in the alternative to the wind power generator 23. In other embodiments, the wind power generator 23 is used in the alternative to the solar power generator 22.
The portable power station system 10 housing additionally includes isolated ground 24 and a ground chassis 25 to allow for proper grounding of the electrical power flowing through it.
