Footstep Power Generation Using Piezoelectric Sensor
Avhad Harshal Dnyandev , , SE-DIV B,(Electrical)
1. INTRODUCTION
Day by day, the population of the country is increasing
and the requirement for power is also increasing. At the same time, the wastage
of energy also increased in many
ways. So reforming this energy back to usable form is the major solution. As technology is developed and the use of
gadgets, electronic devices also increased. Power generation using conservative methods
becoming deficient. There is a necessity arises
for a different power generation method. At the same time,
energy is wasted due to
human locomotion and many ways. To overcome this problem, energy wastage can be
converted to usable form using the piezoelectric sensor. This sensor
converts the pressure
on it to a voltage.
So by using this energy-saving method
that is the footstep power generation system we are generating power.
This project is used to generate
voltage using footstep force. The proposed system works as a medium to
generate power using force.
2. NEED OF SYSTEM
5.
WORKING
The main components of the system include piezoelectric sensors, voltage
boosters, voltage regulators, a PIC microcontroller, a battery, LCD, LDR, and a socket for mobile charging.
i.
The Utilization of Waste Energy foot Power With human motion is very important and highly populated countries.
ii.
India and China where the roads railway stations,
temples, etc., are all over-crowded and millions of people move around the clock.
3. WHAT IS
A PIEZOELECTRIC SENSOR?
A piezoelectric sensor is a device that uses
the piezoelectric effect to measure changes in pressure,
acceleration, temperature, strain,
or force by converting
them to an electrical charge
When a force is applied to a piezoelectric
material, an electric charge is generated across the faces of the
crystal. This can be
measured as a voltage proportional to
the pressure (see diagram to the
right). A given static force results in a corresponding charge across the sensor.
Flex motions, touch, vibrations, and shock measurements all use piezoelectric sensors. They are
used in sectors such as healthcare, aerospace, consumer electronics, and nuclear
instrumentation
4. CIRCUIT DIAGRAM OF PIEZOELECTRIC SENSOR
Fig 1. 1. Circuit Diagram of Piezoelectric Sensor
In the system, two voltage
boosters are used to boost the voltage to get the desired output. The output from the piezoelectric sensor
is in the range of 3 V to 4 V. It has to be boosted to a range of 9 V to 12V with the help of voltage
boosters.
A constant output voltage
irrespective of fluctuations will be maintained by a voltage regulator. This
regulated voltage is stored in the battery and is fed to the microcontroller.
The LCD which is interfaced with the
microcontroller in turn displays the amount of charge stored by the battery.
In this system, the power
generated has been used for two applications such as lighting a street light and charging a mobile
phone. An LDR is used to indicate the street light application
For a PIC microcontroller, 5 V is required for its working. The mobile charging socket also requires 5 V for its operation. A pull-down resistor is used in the socket to pull down the voltage to 5 V.
6. CONCLUSION
In this project, we are generating electrical power as a non-conventional method by simply walking or running in the foot-step. The non-conventional energy system is very essential at this time to our nation. Non-conventional energy using foot-step is converting mechanical energy into electrical energy. By using this energy conservation theorem and Piezo sensor we are proposing a new method for power generation. Proposal for the utilization of waste energy of foot power with human locomotion is very much relevant and important for highly populated countries like India and China where the roads, railway stations, bus stands, temples, etc.
What is EV Charging and how does it work?
Shahu Anokh Rahan, Electrical Engineering (SE-A)
rahaneshahu@gmail.com
I know. You probably want to say, "Just plug it in!" However, it gets a bit more complicated when you dive (a bit deeper) into the answer. Hopefully, this short article can serve as a quick tutorial for those interested, in fact, forward this along to anyone interested in learning the basics of EV charging. Just like a cell phone, EVs need to be charged in order to have enough power to continue to run. EV charging is the process of using EV charging equipment to deliver electricity to the car’s battery. An EV charging station taps into the electrical grid to charge an EV. The technical term for EV charging stations is electric vehicle supply equipment (EVSE).
1. HOW DO YOU CHARGE AN ELECTRIC CAR?
Charging your electric car is even more convenient than refueling a traditional ICE car (except for time, but we’ll get to that later). Your primary option would be to have an electric car charger at your residence which would allow you to charge the car overnight. This means that you wake up every morning with an almost full battery. Of course, not everyone has that option. For those who live in multi-unit dwellings (apartments, condos, etc.) it can be more difficult but charging there is definitely doable. And there are new initiatives making it easier than ever before. Also, when you're away from home, there's a multitude of public electric car charging stations currently being built to further expand worldwide charging infrastructure. Tesla's Supercharger network is a great example of what the future holds for the industry. Your daily route shouldn't, and won't have to change in order to charge your electric car.
2
WHERE DO YOU CHARGE AN ELECTRIC CAR?
While currently there
are not as many electric car charging station companies as there are petroleum
companies (at least not in the United States), more and more are popping up to
provide energy for electric cars as time goes on. Just to name a few
(non-Tesla) networks that are already around and expanding rapidly: EVgo, ChargePoint, Greenlots, IONITY, e.on, and Electrify America.
To make navigating all of the different electric car charging stations easier, we recommend that you look into PlugShare which lists every company’s charging stations in one convenient map. If you have a Tesla, it's even easier. Tesla's navigation will also point the driver to the company's Superchargers and Destination Chargers along any given route. What are the different levels of electric vehicle charging?

3 HOW FAST DOES AN ELECTRIC CAR CHARGE?
Two primary factors determine how fast electric vehicle charges; the amount of energy the charging station can dispense, and the amount of energy your particular EV can accept. As for the supply, there are three "levels" of EV charging.
3.1 LEVEL 1
To start off, we have a Level 1 charger, which is essentially just plugging in your car into your standard household wall outlet. Level 1 charging presents the slowest charging speed as it only provides around 1 kW of power (meaning if you wanted to fill up a 50 kWh battery, it would take you at least 50 hours). Although, this can still be helpful if you own a plug-in hybrid with a very small battery you don't drive your EV very far daily.
3.2 LEVEL 2
Next up, we have Level 2 chargers which are commonly found in parking lots, at businesses, and in private homes. This is the type of charger you would likely install in your garage if you plan on charging your electric car at home. These level 2 chargers provide anywhere from 3-20 kW of power. Meaning that if your charger is anywhere on the higher end of the range, your electric car can be charged to 100% overnight. Most homes in the US have the electric capacity to install a level 2 charger without significantly costly electric service upgrades.
3.3 DC FAST CHARGE (AKA LEVEL 3)
Then, we have DC fast chargers (sometimes referred to as Level 3). These are the chargers that you most likely find on the side of highways and highly-populated electric car areas. These provide anywhere from 20 kW up to 350 kW of power on some of the newest stations being built, such as the Electrify America and IONITY networks. Tesla's new V3 Superchargers can deliver up to 250 kW and are just beginning to proliferate. When charging at these new ultra-high-speed charging stations, you could charge from 0-80% in about 20 minutes.
But hold up, we say possibly because not every car is capable of charging
at these maximum speeds. A BMW i3 or Nissan LEAF, for instance, can only accept
a maximum of 50 kW, meaning that you cannot reap the benefits of ultra-fast 350
kW charging. So before you buy an EV, make sure you know the maximum charging
rate so you're not surprised about that important factor after you get the car
home. In fact, there's no car currently on the market that can take
advantage of that 350 kW maximum charging speed. Currently, the only vehicles
that can charge over 100 kW are the Jaguar iPace, Audi e-tron, the Porsche Taycan, and the Tesla Models S/X/3/Y. However, the Model Y and Model 3 hold the record for the fastest Tesla
charging rate of 250 kW — you'll just need to find one of Tesla's new Supercharger V3 stations that can deliver
such power.
The Porsche Taycan actually can accept the highest charging rate of any EV currently available, at 270 kW. Porsche has even promised to up that charge rate to as high as 350 kW at some point in the future. As you can see, charging speeds have progressed drastically over the past decade and it might only be a matter of time before charging your electric car will be faster than refueling a gas-powered one.
4 WHERE DO YOU CHARGE A TESLA?
Charging a Tesla is not too different from any other electric car.
However, while most North American and European electric cars use a CCS Combo
plug, and Japanese electric cars (except Honda) use a CHAdeMO plug, Tesla uses
a proprietary plug for their cars.
As such, only Tesla owners can use the company's massive
Supercharger Network. Meanwhile, Tesla owners can also use an adapter if they prefer
(note: newer Tesla's have built-in hardware already) to use a charger with the
CHAdeMO plug. In Europe, Tesla also offers an adapter for the European version
of the CCS plug called CCS2. However, in North America, we use CCS1 plug and
Tesla hasn't yet developed an adapter to allow US Tesla owners to utilize
public CCS stations.
Keep in mind, Tesla's Supercharger Network is the most extensive in the country (and the world). However, there's been a bit of a shift (for increased versatility) in the Tesla charging hardware over the years. After the release of the Model 3 on European shores, Tesla opted to equip the Model 3 with a CCS2 plug, also. Tesla is also retrofitting European Superchargers to also have a CCS2 plug in order to provide more optionality.
5. HOW
FAST DOES A TESLA CHARGE?
The
DC fast charge arms race is definitely happening, and that's good news for EV
consumers. Tesla has been enjoying a long lead in regards to charge rate with a
rate of 120 kW for its Model S and Model X which allowed an 80% charge in about 30 to 40
minutes. There was a short period where the Audi e-tron took the crown with a charge rate of 150 kW.
Then Porsche came along with the Taycan's 270 kW rate. It was not long
thereafter, however, before Tesla introduced Supercharger V3 which allows
for 250 kW charging on Model 3/Y and 200 kW charging on Raven powertrain Model
S/
There are three main types of electric vehicle charging:
Level 1, Level 2, and Level 3, mostly known as DC fast charging or rapid
charging.
Level 1 charging can be done through a standard 120-volt wall
plug, which can be found throughout U.S. homes and garages. Level 1 charging is
extremely slow and is typically reserved for home charging during overnight
hours. It can more than 24 hours to fully charge an EV battery through Level 1
charging.
Level 2 chargers use 240-volts and are usually found in homes
and public charging stations. A Level 2 charger is much faster than a Level 1
charger – up to 15 times faster! Level 2 EV charging stations need a dedicated
208-/240-volt outlet, which is the type of outlet used for an electric clothes
dryer. Most homes don’t have an extra outlet of this kind in the garage or
driveway and need a dedicated circuit installed by an electrician. DC
fast chargers or rapid chargers use 480+ volts and are the fastest way to
charge an electric car.
Level 1 and Level 2 chargers deliver alternating current
(AC) to an electric vehicle, which is converted to direct current (DC) by the
EV battery. An EV battery can only accept DC power. On the other hand, a DC
rapid charging station delivers DC directly to the electric vehicle and the
electrical current does not need to be converted. Level 1 and Level 2 chargers
recharge EVs much slower due to the AC/DC conversion process.
There are three types of Level 3 charging or DC fast
charging: Combined Charging System (CCS), CHAdeMO (“CHArge de MOve”), and Tesla
Supercharger. CCS allows AC/DC charging through the same port, cars with
CHAdeMO have a separate port for AC charging.
Not all EVs can charge through a DC fast charger. DC fast
chargers are only used in commercial applications and cannot be installed in
homes for several reasons – homes don’t have the electrical capacity for a DC
rapid charger, EV drivers don’t need that quick of a charge for overnight home
charging, and a DC fast charging installation is much more expensive than a
Level 2 due to the electrical infrastructure improvements necessary. On the
other hand, when it comes to commercial applications a DC fast charging station
may be the ideal EV charging solution for a business. For example, DC rapid
chargers are perfect for fleet charging and for highway public charging
stations.
