Plug in charging  – the newest service of parking  Park and Fly

Now parking Park and Fly has some news for you. The parking offers the service electric cars charging with Plug in contacts, which is a really practical option for electric automobile owners. For the moment the parking offers just a regular Plug in contacts charging  but really soon it will offer more modern charge stations too.

Plug in hybrid automobiles are the latest fashion trend in the development of automobile technologies. They are known as plug-in hybrid electric vehicles or in (PHEV). Petrol or diesel engines of some plug-in car models are used not for propelling the vehicle but for recharging the batteries instead. These cars are called Extended-Range Electric Vehicles or EREV in short. Their batteries charge from the electrical network.

What is Plug in charging?

 Plug in charging contacts have become an important part of our modern way of life and it’s a real necessity for hybrid automobiles owners. These contacts are used for charging hybrid electric cars. For most of us the technology of hybrid cars plug-in charging may seem as something  completely new but in fact it has existed for more time think than we think.  It’s a curious fact that the plug-in hybrid is already 120-years old. This amazing engineering achievement has definitely changed the life of many car owners and has made it more easy and practical so far.

These of you who don’t know about Plug-in contact charging and what are these plug-in hybrid automobiles then you will find interesting info about them in this article.


What are hybrid electric automobiles?


Hybrid electric vehicles are not only cars but also there are hybrid motorbikes, trains, trucks, microbuses, and even armor vehicles.

These vehicles have an internal combustion engine that plays a main role and also an electrical motor whose function is just additional. The automobile is propelled by electricity during a moment of low speed or moment when more power is no longer necessary. The petrol engine starts working only when we need more acceleration and horse power. In this moment the electrical motor ‘s battery is charged by this amount of energy which is designed for stopping the vehicle. Hybrid electric cars’ advantage is that they are really economic because their electric movement enhances the increase in the engine’s power. One of the fastest sport hybrid automobiles are  Porsche 918 Spyder . This sport model car accelerates from 0 to 100 km per hour for around 2.5 sec. Besides, it can last 28 km solely on electrical power. The sport hybrid model car McLaren P1 achieves electrical mileage of 10 km after one recharge.


What are the similarities and differences between plug-in hybrid automobiles and conventional hybrid cars?


Both conventional hybrids and plug-in hybrids have an electric motor and an internal combustion engine. But unlike standard hybrid cars plug-in hybrids have bigger batteries that are charged by a special charge station from the electrical network. Their maximum mileage after one charge is 80 km per hour.

Hybrid electrical automobiles just like the standard hybrid models have a battery that charges from the electrical network or charge stations. But only hybrid electric cars have an internal combustion engine. This engine plays the role of an electrical generator when the battery charge dies.


 What are the advantages of plug-in hybrid automobiles?

Depending on the certain model hybrid electric cars have two times less fuel expense in comparison to automobiles with an internal combustion engine that has the same fuel capacity and size.

Plug in hybrid automobiles has combined all of the advantages of hybrid electrical cars plus the main features of conventional automobiles.


 During city driving conditions plug-in automobiles use mainly electricity and when the battery charge goes down the engine takes over the function of propelling until we find a charging station. The engine can also act as a generator that recharges the batteries during driving.

When we have a plug-in a hybrid automobile that drives on biofuel, biodiesel or ethanol, for example, we can fully avoid the use of petrol fuel.


How plugin automobiles were born?

Как са се появили plug-in автомобилите

The history of plug-in automobiles birth is really interesting. The first plug-in automobile appeared in  1898г. thanks to the self-taught engineer Ferdinand Porsche. And because of his genius, the name Volkswagen was created. In the town of Maffersdorf, today’s Czech Republic, he started working for the famous master Ludwig Lohner who was in the business of carriage production. Ferdinand Porsche had a single task – to create an automobile. Consequently the engineer makes the first vehicle that is propelled by electricity. This discovery was a surprise for the general public then.

But the first automobile the engineer created didn’t turn out to be very convenient for driving. This was because the automobile had huge in size and weight lead-acid accumulators that were adding an additional 1.8 tonnes to the vehicle’s total weight of 4 tonnes. For this reason, Porsche gives up on this project and started creating  Lohner-Porsche Mixte Hybrid. This automobile model had an engine by Daimler. It is connected through a generator that charges the electrical motors.

Each of the automobile’s tires was fitted out with such a generator. This electric car achieved a speed of 56 km per hour which was a remarkable achievement for this time period. The automobile sets a couple of speed records in Austria and in 1901 it wins a rally competition in Exelberg. By this time 300 units from this model were manufactured which was impressive.

 But the lack of quality batteries production and the aggressive company policy of petrol companies urged the production of hybrid electric automobiles to stop for almost a century.


But thanks to the American professor Andrew Frank the concept for hybrid cars was turned back to life in 1969. He published an article for hybrid cars for Popular Science magazine. Later after the end of 2000 several pilot projects for plug in hybrid cars were started by automobile companies.  

The Chinese company BYD started for the first time hybrid automobile mass production. Currently, over 50 plug-in hybrid model cars is offered. From them, more than 820 000 hybrid automobile units are sold.


What is the difference between plug hybrid cars and standard hybrid cars?

 Plug in hybrids are similar to standard hybrid automobiles because they are also divided into 3 kinds: series hybrids, parallel and power-split. In the last decade standard hybrid car models like Toyota Prius for example.


Series hybrid automobiles

The motion of these hybrid automobiles is achieved by an electrical motor. Their generator which has the role of electricity production is charged by an internal combustion engine.



They can be driven by two types of aggregator – one electrical and one with an internal combustion engine.



They work in both ways, similarly to the series hybrids and the parallel hybrids.

In conclusion, both types of cars: electrical and plug-in hybrid automobiles decrease our fuel budget and contribute greatly for keeping nature clean.
