Abstract

Capacitor as energy storage in combination with hand crank generator and charging extension

Description

Self-sufficient storage energy generator

Autarker hand crank / generator / emergency generator with condenser as energy storage even after long periods of use ready for use.

In transportable box (with seating on the lid, in this position can be generated by the hand crank, by a Vor-back movement of the generator rotor, electricity) to wear and pull / push / on belt device also freehand to pull.

Possibility to carry luggage / equipment on top.

With integrated LED lighting that can be switched manually, including cigarette lighter as extra equipment, voltage display in volts DC, USB charging port, 12V vehicle power socket, jump starter connection cable mounted on energy storage.

As well as inverters with 230V for use on vehicle power socket for small consumers and / or loosely mounted 230V inverters for greater short-term power draw also with jump start connection cable, for operation on an external power source, e.g. Provided car battery.

Hand crank - generator based on a brushless alternator without typical transmission gear, with fixed stator winding, and a magnet equipped with rotor by muscle power in rotary motion.

(left or right as well as back and forth / no fixed direction of rotation)

Rectification of the rotary / alternating current takes place in a built-in rectifier / bridge rectifier, which is dimensioned according to power requirements, in order to charge the installed energy store (DC capacitors) with direct current.

The mechanically converted electrical energy can be used for charging or direct operation of small or large consumers.

In an energy storage without conventional battery, such as capacitor, supercapacitor, ultracapacitor or capacitor banks together, or in the future, technically advanced hybrids with a mixture of battery and capacitor or the like, are stored.

This capacitor bank, is housed in a detachable / or permanently installed connection in the housing of the transport box, in which also a part of the mounting of the generator is located and can be removed in a more detachable connection, for. a scooter (tested on a 50cc scooter with e-start function) with a pulse power of previously stored energy

Jump start (light construction).

In this case, the capacitor bank, a starter battery, replaced with a capacity of 7 Ah (25,000 As). Other applications could arise after further testing.

Also conceivable as a car start-up aid.

The generator is mounted on a rigid and torsion-resistant mount on which the rotation axis of the generator rotor is ball-bearing. The actual generator sits outside the transport box and thus allows the load by pulling / pushing during transport via a belt drive in conjunction with a transport roller.

The electrical storage capacity is variable and expandable, adapted to the performance of the generator used accordingly.

In the demo model, a capacitor bank was installed, with the following data:
Operating voltage Max. 15V DC Capacity 58 Farad

From this data results at a maximum charging voltage of 14.4 V DC $$\begin{array}{cc}\text{Q}=\text{U}*\text{F}=\text{X}=\text{ace}& \text{Q}=14.4\text{V * 58F}=\end{array}835.2\text{A / s}$$

This means that there are approx. 835 amps available after charging for 1 second. This output can also be taken in one minute. $$\begin{array}{cc}\text{Q: T}& \text{Q}=835:60=\mathrm{13,916}\text{A}/\text{min}\end{array}$$

Or over a period of one hour Q = 835: 3600 = 0.2319 A / h (232mA)

In Watts this would be P = U * I = W $$\text{P}=14.4\text{V * 835A / s}=12042\text{W / s}\left(\text{12KW / s}\right)\mathrm{,\; 200.4}\text{W / <figure-callout id="3" label="min" filenames="DE202019000566U1\_0005.png" state="{{state}}">min</figure-callout>}\text{3}\text{, 34W / h}$$

To take this power of stored electrical energy,
Is with mechanical force to perform a mechanical work with the hand crank for about 7 minutes. By a relatively pleasant rotation speed over this period, the memory is charged with a current of about 2 amperes.

This was determined with a measuring device.

The faster cranked - the more charge current or the slower, the less charge current.

Charging behavior by pulling the transportable box:

100mV per drawn 70 meters, 7m = 10mV, fully loaded to 14.4 V after about 10 km at a walking speed of about 3.5 km / h.

Again, as in cranking, the statement, the faster pulled, the faster the energy storage is charged by increasing the charging current.

For example, as a bicycle trailer about 18 km / h, or by increasing the pace.

However, the charging time can also be changed by adjusting the gear ratio (pulley size) of the drive wheel / tire to the generator rotor.

It can be provided by appropriately sized capacitor banks, and inverters also short-term greater performance after charging the capacitors by the hand crank, or generated by modular extensions drive energy to operate various household / machine tools in the short term or longer.

Also devices from the vehicle electrical system can be supplied or external batteries, mobile phones, etc. are charged.

Overloading of the capacitors is avoided by a suitable built-in charge controller.

This ensures that from a certain generator voltage, the capacitors (or charged for charging batteries) are no longer recharged.

No matter with which rotational speed the rotor is then moved.

Reversible generator / motor operation in modular design as an extension

In the transportable box 2 main switches were installed, which enable a switch from generator to motor operation.

For switching, the main switch Q1 (Generator mode) is set to 0 and provided with a switch-on inhibit.,
In the following step becomes the main switch Q2 (Engine Operation) is set to 1, thus releasing the previously stored energy to a suitable BLDC controller.

In this mode, the rotor of the generator can be used as a drive to drive e.g. a whetstone (which has been tested in the box) or another generator (also outside the box) to drive on the rotating shaft.

The generator, here e.g. a DC generator could serve as an additional way to recharge the memory, (function and feasibility, would have to be tested in further tests) while the rotor in the motor mode takes over another drive function.

Conceivable here also to support the box uphill as a driving aid (in further development by adapting the drive ratio of the central axis of the rotor to the drive wheel and extension or exchange of the currently used component groups), or to operate with an externally connected consumer via a belt drive.

Optional accessories were continuing, clip-on handles (on the pull-out handle of the box) with an electronic throttle / cruise control that connects to the external BLDC control box (Driver Box).

The required BLDC control for motor operation was designed as an external plug-in device (Driver Box) with a supply line and plug and is not permanently installed.

Thus, it can be unplugged and stowed in generator mode.

It was only the coupling socket integrated in the housing of the transport box.

Before the BLDC control, a suitable DC step up converter or similar could be installed to increase the available DC voltage of max. 14.4 volts after charge, on e.g. 30V DC, to achieve an increase in engine speed. (Was simulated with a laboratory power supply)

At the current maximum charging voltage of 14.4 V DC, the built-in BLDC control achieves a maximum speed of 42 revolutions per minute.

The current consumption during idling here is about 180 mA (0.18 A)

Under load on the rotary shaft, which can hardly be brought to a standstill by hand without tools, the absorbed current only increases to 380 mA (0.38A).

The motor has a high torque at this power consumption!

If I increase the voltage to 30 V DC as determined with the laboratory power supply, the speed increases to around 90 revolutions per minute.

When using the reversing direction of the control, make sure that the rotor of the motor has come to a standstill before it is switched over in order to put the motor in a different direction of rotation.

Features and Benefits of Energy Storage in Capacitors with Hand Crank Generator:

The advantage of the capacitors as energy storage for the hand crank generator, is that the capacitors are much less sensitive to the ambient temperatures, as is the case with batteries.

According to the manufacturer of the capacitors, which are currently used in the portable box: - 40 to + 120 degrees Celsius

Especially at minus temperatures, where other power storage quickly reach their limits or completely fail. Long service life does not affect the capacitors, as in a conventional battery, which eventually discharges deep and thus becomes useless as energy storage.

Vibration or the location / installation of the capacitors is much more flexible than e.g. with an acidic battery.

The weight is also crucial in a portable version of the emergency power hand crank generator.

The charging cycles of the capacitors instead of about 1000 cycles in batteries at about 1,000,000 cycles in these capacitors.

In addition, a battery is based on a chemical reaction during the charging process, which takes longer than the capacitors used to save the power.

Disadvantage:

High self-discharge of the currently used capacitors.

In this case, neglect, since only electricity is generated when it is needed.

The generator was not designed for long-term energy storage.

Application / marketability:

Ideal generator for crisis prevention in general or especially for prepper, in the outdoor area, construction site / expedition / military etc. or home in case of power failure due to storm, earthquake, solar storm (EMP), energy shortage, war, terrorist attack or the like.

But also for the constant production of own electricity in small quantities.

Actually, for the entire population of all countries, which recommends that the government also provide food for crisis situations, here called, for example, the Federal Republic of Germany.

Can be stored unused for a long time (without the energy storage under deep discharge) but just as used every day to use, for. Mobile / Akkuradio, Netzbetriebenes radio (news / instructions of the authorities / government in case of crisis) / Akkulampe, etc. to load.

1. 1. Nahezu geräuschlos
2. 2. Keine Abgase
3. 3. Autark und treibstoffunabhängig
4. 4. Keine Brandgefahr / Explosionsgefahr des Treibstoffes

Advantage of this generator, which is powered by muscle power, in contrast to a gasoline / diesel power generator, as follows to see the examples:

1. 1. Virtually noiseless
2. 2. No exhaust
3. 3. Self-sufficient and fuel-independent
4. 4. No risk of fire / explosion of the fuel

What's the point 3 , In a collapse and prolonged failure of the power supply and the lack of supply of fuel would quickly lead to very quiet and dark days / nights, when gradually commodity-dependent emergency generators fail and fall silent. (or very loud / bright riots and fires where everyone will chase the last drop of fuel and batteries)

People are afraid in the dark, that has always been and will remain so.

If the last candle goes out, that is the remedy.

Actually, it is an endlessly light generator with decent performance, as long as I occasionally crank, or operate with an external drive.

The question of what I do in case of power failure, so as not to sit in the dark, inspired me to build this functional prototype.

As my previous research on the Internet showed, there is currently no comparable product in this category, which is available for purchase.

Market analysis marketability

Leaning as an example to the population of the Federal Republic of Germany, with approximately 85 million inhabitants representing 100%, I would just like to set out a possible calculation example.

Actual potential sales figures are to be determined under consideration of more accurate market research.

85,000,000 inhabitants roughly corresponds to a total of 28.3 million households divided by 3 people. That would be at 10% 2833333 households 1% 283333 households 0.1% 28333 households 0.01% 2833 households

Assuming that these 0.01% = 2,833 households are distributed in villages with about 3000 inhabitants, roughly a number of a potential provision buyer of the product would result in every third place.

This is a figure that is almost identical to the one I was able to make in the event of a power outage due to my experience in talking to customers in my profession.

Very small, in each 3 place one of the emergency care shows interest.

Personally, I find it very scary that in the event of a collapse of the energy supply the entire population would be on its own.

Even more frightening is the fact that most people are unaware of what such an outage over a longer period of time would mean for each individual.

If this were realized and disseminated through targeted marketing, in my view, an increase to the 0.1% shown above, with 28,333 households real that I could address.

From scaremongering I would like to refrain here and take distance.

But if there was a so-called run on this product, e.g. after a possible recommendation from the Federal Government to the population that would help only to protect and self-supply of electricity in very small quantities, is quite conceivable that even 1% = 283,333 of households this recommendation could follow.

Production price and selling price, as well as the resulting profit on sale, is yet to be determined in more detailed analyzes.

As an example, only the FRG now serves.

As a next step, I would think this on the 30 Economic strongest nations on.
283 thousand times 30 = 8,490,000 possible buyers.
Continuing to export almost to the whole world, I assume about 150 countries.
283 thousand times 150 = 42,450,000

Starting from around 100 € profit, I would be at 424.5 million euros profit.

Product in production about 300 -400 € Sales depending on equipment 500-600 € also only rough estimate.

Reduced again to 0.1% of households, I would still be at a profit of 42.450.000 €

This was just a thought experiment, actual profit and sales may differ.

Annotation:

Only components mass-produced in series have been used in large numbers for simplified accessory purchase.

Only various small parts and cable connections were made by hand.

Production costs of the generator are currently only approximately to be measured, since the components required are very high in terms of unit costs, to make dependent on the suppliers.

From me only single pieces were requested.

The assembly in a routine manufacturing process is according to my estimates rather low and not very time consuming.

With adequate supplier prices, I estimate the material costs for the generator / engine depending on equipment features, in the range of a commercial washing machine or rather less. (almost every household has its own washing machine)

After a test phase in the flying structure, a functional prototype was personally produced as a demonstration model / sample.

Through the construction of the prototype, the copyright arises from my intellectual property, which is created informally on the basis of the real act of the creation of the work.

Intended with this application are the industrial property rights.

Naming / Finding in own production and the related sales completed / possibly to be announced as a proposal when licensing.

All components are state of the art.

They were combined in this product in a logical and inventive way by myself.

The hand crank generator in itself, was extended by my innovative charge possibility during transport by pulling or pushing through a design change of the rotor to external drive possibilities. The battery as power storage has been replaced by modern capacitors.

The switch from generator to a motor, using the main switch and the help of a BLDC control, opens up completely new possibilities for future technological developments, according to personal assessment, is the forward-looking.

Enclosed are 2 drawings with side view of the transportable box, with the main features of the drive device, as well as a circuit diagram, the electrical components.
