Week 5 [23.11-29.11] Electric cars make sense

 

Electric cars make sense

 

What's interesting now in the automotive industry? Of course, the first thing you think about are autonomous cars. Recently, talking about autonomous cars has become as fashionable as “data science” in the IT industry. This time I don't want to focus on them for one simple reason. We don’t have a road infrastructure where we could set the autopilot. First of all, it's dangerous and if I’m not mistaken it’s still prohibited by Polish law.

 


Let's focus on technology closer to us – electric cars! You will be surprised how many of them are on our streets. I bet you've seen this cute car from the photo above on Warsaw's roads!

 

It's time for some statistics.


Number of electric cars in the world in individual years:



What a huge increase in the number of electric cars in recent years! 
At the end of July, over 13,000 electric cars were registered in Poland. This is a good result considering that such cars are present mainly in larger cities. I'll tell you why in a moment. 
Summarizing the above it’s a technology that has settled for good and is the future of automotive and transport.


Historical curiosity 

 
The first electric car in the United States was developed in 1890-91 by William Morrison of Des Moines, Iowa. The vehicle was a six-passenger wagon capable of reaching a speed of 23 kilometers per hour. 


 

Specifications for the 1890 Morrison Electric included 24 storage battery cells mounted under the front seat. The Morrison designed and produced the batteries. Finally, the motor developed about 4 horsepower… which is as much as our mowers today. 

 

Let's go over what is most interesting in electric cars - performance!

 


 

This video shows the extreme possibilities of both internal combustion engines and electric drive. Seemingly, this has nothing to do with an electric car such as the BMW i3 that we can rent in Warsaw. However, one feature of electric motors is very clearly presented here, in which they predominate over combustion ones. Maximum torque is available immediately! Put simply, the car accelerates instantly after pressing the gas pedal with great force, giving a feeling of being pressed into the seat. Classic cars with an internal combustion engine have a moment of hesitation before we feel them accelerate. I can assure you that the BMW i3 from the famous rental company can also surprise you with its fast acceleration.

 

Another undoubted benefit – silence

 

Imagine driving a car hearing only the noise of tires and air, with the silent whistle of the electric drive in the background instead of the loud drone of the diesel. Isn't it beautiful? If you don’t like silence and want to feel like in a petrol car, you can turn on the simulation of the sound of petrol engine in the car speakers. I don’t recommend this because it sounds artificial.

It’s clearly noticeable that at low speeds the volume level inside the car is much lower in an electric car. The differences blur at higher speeds, but I would like to mention one detail. The internal combustion engine has a pronounced peak at 63 Hz which means low bass registers. It’s this frequency that makes us uncomfortable with prolonged listening. The electric car wins!


How to refuel it?

 

  • At home - you can just plug it straight into your domestic mains electricity supply. The problem is this is slow. It will take many hours to fully charge an empty battery. A faster option is to get a home fast-charging point installed. The government will pay up to 75% of the cost of installation so it pays off.
  • Public charging points - firstly, they are paid, although still cheaper than fuel. A serious problem is that there are very few of these chargers and we can find them mainly in large cities. We have only 1,282 public chargers in Poland, which means that we must plan our trip wisely.


Is it really eco-friendly?

 

An electric vehicle causes less environmental damage over its entire life cycle than petrol car. It’s mainly due to the fact that they emit much less greenhouse gases. In the case of electric vehicles, the production and disposal of cells have the greatest environmental impact. Overall, cars can be considered environmentally friendly and the cell utilization process is constantly being improved.


Currently, the fastest mass-produced electric car



PORSCHE TAYCAN TURBO S
750 horsepower
2.5-seconds to 100km/h

 

 

Questions:

  1.  Do you think William Morrison would be proud of today's electric vehicles? Or maybe the development of electric cars could go the other way?
  2. Have you ever driven an electric car? What is your impressions?
  3. Do you prefer the sound of internal combustion engines or electric silence? Why?

1. Do you think William Morrison would be proud of today's electric vehicles? Or maybe the development of electric cars could go the other way?
If you show him the comparison in speed in my opinion he should be amazed by them. No idea if their development could be change in previous year, but they should develop better ways of manufacturing such engine. When we eliminate the tons of CO2 that are emitted in this process then electric cars really will be better and more green then let say a car with LPG.

2. Have you ever driven an electric car? What is your impressions?
I can't tell as I never had a chance to even be in one of them. ONly in electric buses.

3. Do you prefer the sound of internal combustion engines or electric silence? Why?
I prefer electric silence but I know it is dangerous. For animals and blind people for example. They may not hear tires fast enough to react let's say when passing the road.

I think that today's car development is going in the right direction. Even if we are not talking about electric cars, machines are built in such a way that they do not pollute the environment. Of course, cars lose their performance, but you have to survive it...
Electric cars are an interesting thing. An important thing for development is the availability of charging stations for such cars. So as the world moves in this direction, there will be more and more electric vehicles on the streets.

2. Have you ever driven an electric car? What is your impressions?

Yes, I had the opportunity to drive an electric car. This is a nice option for the city. Acceleration allows you to move more dynamically.

3. Do you prefer the sound of internal combustion engines or electric silence? Why?

I prefer the sound of internal combustion cars, especially when it is a large engine. I also know that electric cars have loudspeakers installed to imitate an internal combustion car, but I consider it a fake.

1. I think electric cars are a groundbreaking invention. In many countries around the world they fulfill their tasks and assumptions. However, electric cars in countries like Poland do not make any sense. To produce the electricity needed to run a car, factories need to emit more CO2 and other chemicals into the atmosphere than the average gasoline car. If we were to use almost 100% renewable sources like Iceland, this idea would not miss the goal. I think hydrogen cars are a real opportunity for our planet.

2. I have driven a BMW i3. Linear acceleration and no gear ratio is a really interesting experience. But I wouldn't say this car is quiet. The screech this car produces is annoying to me. I didn't feel good driving this car. Hope Tesla would do better :)

3. As I mentioned, I have not experienced electric silence so far. Only electrical annoyance. I think I prefer gasoline and diesel cars. Especially diesel. I really like the sound of these motors and the torque. Of course, I mean units with a reasonable engine capacity - max. 3 liters. Larger units are expensive to maintain and more harmful to the environment.
1.Do you think William Morrison would be proud of today's electric vehicles? Or maybe the development of electric cars could go the other way?

Electric cars are constantly evolving, getting better, but never equal to internal combustion cars. Why do I think so? Because when you run out of electricity, you need a minimum of 1 hour to charge. Even this beautiful Porsche Taycan has a very limited range, so it is only suitable for showing off around the city. In general, I think that electric cars only work in developed countries, possibly in cities - in other places they do not make any sense. In my opinion, car makers spent a lot of money developing electric cars, now they have to get back that amount. However, electric cars are not the future in my opinion. I believe that synthetic fuel engines are the future. The exhaust from these engines is water. It is not a new technology, because already during the Second World War, all German tanks were powered by synthetic fuels obtained from coal. The news comes to light that Audi has developed such an engine.

2.Have you ever driven an electric car? What is your impressions?

Yes, I had the opportunity to drive an electric car. I liked the generally available torque - the car was dynamic. However, as it turned out, the battery drained quickly and I had to change to a car with a combustion engine. In Poland, electric cars do not make sense. They are not ecological at all - electricity in Poland is produced from coal, they are not cheap - the costs of purchasing electric cars are much higher than those of internal combustion cars, electric cars are not durable - batteries have a lifetime, my question is what to do with used batteries later?

3.Do you prefer the sound of internal combustion engines or electric silence? Why?

I am a fan of motorization and mechanics, so I prefer internal combustion engines. Nothing can replace the sound of a V8, V10 engine and 12 cylinder engines. I don't like when electric cars have programs that imitate the sound of other engines - it's such an internal lie in the style "I want to be a strong and loud internal combustion engine".

Olga Przytula said…
I think at the time he would imagine that electric vehicles would be a predominant mean of transportation by now.

As I live in the city center of Warsaw I don’t have the urge to buy a car to use on everyday basis (especially during the COVID times, where there is nothing interesting to do on your free time). However, every time the weekend comes me and my boyfriend rent an Innogy car - BMW i3 – some kind of electric car anyway. They are quite cheap to use and I guess they can be quite pleasant to drive. Unfortunately I cannot comment on the quality of driving myself, as we rent this cars mostly to train my boyfriend (he’s earned his driving license less than a year ago and we want to pull up his skills)

Now, that we have had a chance to try out the comfort of silence while driving the electric car, I must admit it’s something that feels to me like some kind of luxury :D Don’t get me wrong – I do love driving, I have nothing against riding fast. There is just something so soothing in the way these cars work. It’s like they are not even on while you are driving. Maybe except of the starting part, that make this funny yet delicate kind of noise. I find it quite amusing.
@Karol Michalak

Thank you for opinion. You absolutely have to drive an electric car as a driver because it's an amazing experience.
I agree with you that silence can be dangerous. Accidents often occur in parking lots because passersby cannot hear the electric car.
@Piotr Marchewka

Thank you for your comment Piotr. Tell me honestly, would you be irritated by the sound of an internal combustion engine in an electric car coming from the speakers? This is a very hot topic these days. As far as I know, the vast majority of people dislike the imitation of the sound of an internal combustion engine because it sounds very artificial.
Besides, congratulations on driving an electric car!
@Maciej Antonik

Thanks Maciej! I understand your point of view and somewhat agree. In Poland, these cars make sense, provided that we live in a large city and only want to move around it. Especially if we have solar farm on the roof of the house and we can charge the car with solar energy. Even in Poland it is a great idea but requires careful thought.

The BMW i3 is a small city car in which silencing the interior was not a priority for the manufacturer. In addition, I presented in the presentation that at higher speeds, the difference in volume between an electric car and a combustion engine is not so large. What separates them the most is that in an electric car you hear a whistle and in a combustion car a bass hum. These low frequencies in a petrol car will be more tiring on longer journeys.
@Olga Przytula

Hi Olga. Thanks for the opinion and I will say right away that I agree with it. I hope your boyfriend has a lot of fun driving this car too. Just make sure that he doesn't accidentally press the gas pedal too hard because this car can surprise you ;) The BMW i3 is a small, agile, comfortable car that works perfectly in urban conditions and, as you can see, also suitable for learning to drive a car.
I don't really see any other development path for electric cars at this point. I think Morrison would be definitely proud that the idea itself is not dead and is a direction that professionals consider the future of personal travel.

Yep, I was driving in an electric car and even had a chance to drive it as a driver, not passenger. It was the Renault Zoe, an extremely ugly car. For the first minutes, I had the impression that the engine was not running and the car was rolling downhill. Zoe is a small and tight model, and in addition, the version I was driving was very poorly equipped. I'm not a fan of cars, but I love to drive. I really appreciate the experience, but I would definitely not want specifically this car as my only option. The biggest problem for me with electric cars is range. This is the main aspect that needs improvement.

Like I said, I am not a motoring enthusiast and I don't see anything interesting about the sound of the engine. On the contrary, I think cars should get quieter, both for the sake of citizens and for drivers or passengers. What matters to me is the driving comfort and the possibilities offered by the machine, not attracting the attention of passers-by.

1. Do you think William Morrison would be proud of today's electric vehicles? Or maybe the development of electric cars could go the other way?
I can't tell if he would be proud. Maybe he hoped for something else. But I'm sure he should be satisfied with the current result of electric cars.
2. Have you ever driven an electric car? What is your impressions?
I have never driven an electric car before. I'd love to try it as i heard that experience is really valuable. It's important to try something before you actually have a strong opinion about it.
3. Do you prefer the sound of internal combustion engines or electric silence? Why?
I feel like the sound of a real internal combustion engine is just brilliant. It makes me feel like i have more power over machine. Also I might be wrong but I think it's easier to control the beast as you can feel it and hear it more.
1. Do you think William Morrison would be proud of today's electric vehicles? Or maybe the development of electric cars could go the other way?
I think he could be proud of this. As you mentioned he created first vehicle which was capable of reaching a speed of 23 kilometers per hour. Currently vehicles can reach a lot of bigger values and it is keep improving all the time.

2. Have you ever driven an electric car? What is your impressions?
I didn't but it should be interesting experience. In nowadays this cars can also automaticaly drive from place to place without driver but it is not safest sollution yet.

3. Do you prefer the sound of internal combustion engines or electric silence? Why?
I think it depends. Sometimes it would be nice to have completly silence in car but more often i think sound of internal combustion engine is better for me. I like to hear car and the way how it is working.
1. I think William Morrison would be embarrassed by today's vehicles that so little has changed in 120 years. Let's face it, it's a very slow process and a very slow development that has really grown stronger in the only last 10 years.

2. Yes, I was driving an electric car and my feelings are very positive. Using torque is not comparable with internal combustion engines. However, one thing bothers me - silence, which may be the cause of numerous accidents on the road. Already during my first ride, I noticed that pedestrians do not look around at all on the pedestrian crossings if they cannot hear the vehicles around them, which is why they enters under the cars wheels.

3. Personally, I prefer the sound of an internal combustion engines. It seems to me that when the engine is running louder we feel more pleasure from driving.
@Karol Sołtysiak

Thanks for sharing your opinion. In conclusion, you have a very practical approach to motoring. You don't see anything exciting in the cars, apart from the machine that is supposed to take us from point A to point B. I understand your approach as much as possible and it is for people with such requirements as yours that the automotive industry is shaped by presenting new electric or hybrid car models. There is a chance that in a few dozen years there will be silence in the cities!
@Przemysław Witek

You have to take an electric car as a driver! I think you will change your mind about the sound of the combustion engine and convince yourself of electricians. Well, unless we compare the electric drive to V8 engines, the possibility of enjoying this gurgling is something more interesting than the noise of electricity. The difference is that the large combustion engine will tire on longer journeys and the electric motor is unobtrusive.
@Paweł Bluszcz s20080

It is a pity that the potential of the electric drive was discovered so late. The technology has been known for years but forgotten.
Did you often honk because pedestrians didn't hear you? ;)
Viktor Ryś said…
1.
Yes, I think he would be quite proud, his first trials with using batteries to power forms of persoanl transportation were quite primitive nevertheless it made some ground for future research in this field.

2.
Unfortunately I haven't. I've watched however some reviews on youtube of electric cars and they seem quite amazing.


3.
I think it's a subjective matter, but I like to hear the engine working so I would pick the first option.
Jan Bryński said…
1. Do you think William Morrison would be proud of today's electric vehicles? Or maybe the development of electric cars could go the other way?

Well, definetly. I think that today's electric cars are very advanced and a huge leap toward healthier environment. Frankly, I cannot imagine another direction in which development of electric vehicles could go.

2. Have you ever driven an electric car? What is your impressions?

No, I have not but I'm looking forward to do that. I think the quickest way to achieve that is to register for the Innogy Go. These little cars are cool and I find them adorable.

3. Do you prefer the sound of internal combustion engines or electric silence? Why?

I love the way classical, petrol engine sounds, especially those with high cylinder capacity. Since, I have never driven or been inside an electrical car I cannot say if I like their "silence" or not. However I think I would find it pleasing since these vehicles are possibly better suited for listening music inside than classic cars.
Interesting presentation. Answering your questions:

1. I think so. William Morrison would be proud of today's electric vehicles. He would be glad that his idea has developed and is more and more useful and environmentally friendly.

2. No, I have never driven an electric car, but I had the opportunity to drive a Tesla around Warsaw as a taxi. It really impressed me - the car is incredibly quiet and has very high acceleration.

3. Good question. I think both are interesting. It's very nice to hear a V8 or V12 combustion engine, but on the other hand I also like silence and, most importantly, ecological environment.
Do you think William Morrison would be proud of today's electric vehicles? Personally, I think he would be quite impressed with its development. However, I guess he would be disappointed with its popularity today. The market for cars powered with alternative sources is dominated mostly by hybrids. The reason for this is the small number of chargers outside of big cities, which limits the use of purely electric cars to only driving within them. Hybrids give the advantage of the range extender, which often are diesel engines, with which you don't have to worry so much about the capacity of the batteries. However, they still contribute to air pollution. The main disadvantage of hybrids and electric cars is the price, development and production of batteries and propulsion system for it is more expansive than the production of cars with internal combustion engines. However, the utility costs and maintenance for an electric car is much lower, than constantly paying for gas.

I work in the industry of electric engines and batteries, and so I have driven hybrid and electric cars many times. The company in which I work produces batteries for electric buses and in the past, it even created one of the first polish-made electric car. Personally, I prefer plug-in hybrids, as I often travel long distances and its easy to charge at home. I would like to switch to a fully electric car, but unfortunately, on my usual route, there are not many chargers.

I prefer electric cars and buses, as they don't contribute to noise in cities and air pollution. However, if they don't create even an artificial sound, they can be potentially dangerous. Pedestrians are used to hearing a bus or car when it drives by, but the electric ones don't make much noise.
Do you think William Morrison would be proud of today's electric vehicles? Or maybe the development of electric cars could go the other way?

Yes, I think that he could be proud of today's electric vehicles. In my opinion, the electric cars industries are growing and evolving in the right direction

Have you ever driven an electric car? What is your impressions?

Unfortunately, I don't have an opportunity to drive an electric car yet, I hope that I will have an opportunity to change it in near future.
Do you prefer the sound of internal combustion engines or electric silence? Why?

I think that I prefer the sound of internal combustion engines :)

1. I think so. Current electric car industry is growing rapidly. Downside is that there are not many chargers in public places, and range of electric cars is not large enough. However, within a dozen or so years, in my opinion, there will be more electric cars than combustion cars
2. I have never driven an electric car, but I have driven it. I believe that they are better than combustion cars because they are quiet, and they do not harm environment as much as internal combustion cars. When driving such a car, acceleration is much faster than in a typical car because of engine
3. I prefer sound of electric cars, it is friendlier to ear in my opinion. Sometimes when walking down street and being tired, sound of a loud engine from a car can be irritating, with an electric car you don't have it

Week 12 (12.01-18.01.15) Are you an early bird or a night owl ?

Owls are nocturnal creatures. They’re wide awake at night and they sleep during the day. If this sounds like bliss to you, then, like about 20 percent of the population who find themselves most active at around 9 pm, you may fall into the same category as our feathered friend. Night owls often have difficulty waking up in the morning, and like to be up late at night.  Studies of animal behaviour indicate that being a night owl may actually be built into some people’s genes. This would explain why those late-to-bed, late-to-rise people find it so difficult to change their behaviour. The trouble for night owls is that they just have to be at places such as work and school far too early. This is when the alarm clock becomes the night owl’s most important survival tool. Experts say that one way for a night owl to beat their dependence on their alarm clocks is to sleep with the curtains open. The Theory is that if they do so, the morning sunlight will awaken them gently and natura...

Week 11 [03-09.06.2019] The problem with ecological cars emission in UK

The problem with ecological cars emission in UK Since the adoption of the European Emission Allowance Directive in the European Parliament, all car makers have tried to submit. Since 1992, the Euro I standard has been in force, which limited the emission of carbon monoxide to the atmosphere. The Euro VI standard currently applies, which limits the series of exhaust gases. These include: hydrocarbons, nitrogen and carbon oxides, and dust.   The most significant change was brought by the Euro IV standard. For the first time it introduced the limitation of nitrogen oxides, which are responsible for the harmful compounds of smog.   What is smog?   Smog consists of sulfur oxides, nitrogen and carbon. In addition, solid substances such as suspended dust (PM). Dust suspend in atmospheric aerosols may be in liquid and solid form. These can be particles of sea salt, clouds from the Sahara and artificial compounds made by people. These compounds...

James Veitch is a British comedian. In today’s Ted Talk James with characteristic for himself a sense of humor shows how he deals with spam emails and why responding to junk messages may be sometimes dangerous. Questions: What do you think about James’s  way of dealing with spam? Why are junk messages legal, even though it sometimes may be a fraud? Dou you have a problem with spam? How do you deal with with it?
