This is the paper written based on the articles discussed in this blog.
This is the final post for Stef and my blog. This blog starts a little shaky, but eventually we found a thread for the story we want to tell. First of all I created a global setting surrounding electric vehicles and batteries. Afterwards we stated that the energy carrier is the key to electric transportation. We’ve done some research and reported remarkable news on this topic.
Later on I’ll post the paper based on the information visible on this blog. Please feel free to keep reacting to any of the posts.
After reading this article , i had an idea.
People do not tend to buy an electric car because the range is to small. They would like to have a range similar to their current car ( about 800 km) despite the fact that the distance they travel every day is well in de range of electric car. Most people say that when they go on holiday it would be very hard to do that in an electric car. For this problem I had an idea:
Make a market where you can hire/lease a car for going on a holiday.
For just hiring a car , it is already possible but a lot of people do not see this as an option.
But you need to go to their place to pick up the car.
I was thinking about swapping cars for a periode of time. For example: you hire a car for 10 days. They bring that car to your place , they take your with them and store it safely. After 10 days the come back with your car and swap cars. Both to a inspection of the car so that the state of the car is the same as before.This does not need to be with an company that owns cars but could also be done with common people.
Are you more interested in buying a electric car if there was a car available for long distances ?
This technical describes every aspect of the electric vehicle. It is very interesting if you want to know what the future for electric vehicle holds.
Here is a short list of all the obstacles we need to overcome:
Infrastructure (loading points or battery swap points)
Vehicle range ( related to price of battery)
In this post, I wish to speak about grid adaptation. Our grid is not ready for mass use of EVs. In the graph below, you can notice the loading of 20 million EV for a period of 5 hours beginning at 6 P.M. This simultaneous loading of the batteries induces an enormous peak in power demand. This peak can be problem if it occurs during regular peak hours.
If the EVs could begin charging at 11 P.M. the EVs would charge during night hours and the higher demand of electrical would not give substantial problems.This arises another problem. People probably won’t wait till 11 P.M. to charge their cars, but will do this around 5P.M. when they arrive from work. Right beside the normal peak that the electrical grid needs to provide.
Another problem for the grid are fast chargers. They have a high power demand and the local grid needs to cope with this.
Who will pay for these infrastructure costs? The government?
Than everybody has to pay for it and it will be the same everywhere, but very likely it will not be at the cheapest price.
Maybe the private sector can pay for it?
Than only the customers will pay, but the solution provided by the private sector will be focused on short-term profit and leave room for manufacturers to have their own loading stations.
Mit researcher have developed a new battery. A rechargeable, membrane-less hydrogen bromine laminar flow battery. This battery looks very promising. It has 3 times more power than other membrane less batteries and a higher power density than must lithium ion batteries.
But the biggest breakthrough is the cost of it. Because they use Broom , a metal that is abundance on earth ( 243,000 tons produced each year in the United States alone). it drops the cost significant. Also because the don’t use a membrane is drops the cost even more. A membrane is a costly part .
They solve 2 problems that batteries have, cost and performance. If they can mass produce it the total cost will be around 100 $/kWh , a goal that the us department set that batteries will be economically interesting.
hopefully this battery will come soon to the market
there is a paradox around charging points: there are no charging points because there are no electric vehicles. there are no electric cars because there are no charging points.
if you think about it than their is a lot of truth in this sentence. Without help from the government the electric car could no compete with the combustion engine because of the infrastructure that is already exists for the combustion engine. ( just think about how many petrol stations there are)
Now this will change because the EU has set a goal for Belgium to build 21.000 charging points by 2020. But not only for Belgium but every country of the EU has his own goal.
This is good strategy because it unified for the EU, if you would go on an holiday with your car than you could charge your car also abroad.
blog based upon article : http://www.technologyreview.com/featuredstory/422133/will-electric-vehicles-finally-succeed/
In this article they talk about what is now available , what the future will bring and what the battery need to improve to become competitive for a combustion engine. The biggest problem with batteries now is the cost to manufacture it.
Today is cost around 600 to 850 dollars per kilowatt/hour to make it. But the us department of energy calculated that if the battery would cost between 168 and 280 dollars per kiloWatt/hour , the electric car will be competitive with the combustion engine. Economics of scale can bring that cost down but not enough. We need an innovation that cuts the cost drastically. Plug in hybrides could be the next step in to driving more electrically. If the plug in hybride car has an 20 mile range pure electrically it could be used for 25 % of miles driving in U.S. If that car would have a range of 40 miles , 32% could been driving electrically . What gives that we safe 1/3 of our fuel consumption. But it comes today with a cost. The battery cost 3x times more for the 40 miles range car than for the 20 miles rang car.
On the other hand , an electric car that has a range of 100 miles it could by used for 90% of our household vehicles trips. (http://www.afdc.energy.gov/vehicles/electric_basics_ev.html)
Should we first have gentle transition and first have hybride cars?
Then people could learn what it is to drive electrically or make a big leap and go fully electrical which will have the biggest impact on pollution by cars.
