Electric Vehicles – Some Formulas For Charging Batteries

Electric Vehicles – Some Formulas For Charging Batteries

There is really progress going on in the field of electric engines. Electric engines are already four times better than internal combustion engines. The technology to bring pure plug-in electric vehicles to the road does already exist. The only restrain is the presence of efficient battery solutions; batteries allowing recharging to be done at an affordable cost. The upcoming years, will see a drastic change in the composition of cars on the road. Most automobile companies are already developing special electric car models.

An advantage of electric engines is that they make use of the energy generated from braking. This heat is usually wasted. This means that these vehicles are perfect for urban distances where lots of braking is done.

In addition, there are fewer mechanical components – this reduces the operation cost of the vehicles. The cost of driving electric vehicles has for the first time in history decreased to a highly competitive cost. Electric vehicles are even more cost-effective than typical diesel and gasoline vehicles. This motivates the development of the electrification of the transportation sector.

Of course, transforming the road system will take time and requires creativity. Irrespective of the amount of effort required to realise the introduction of greener cars has a phenomenal profit potential.

Plans have already been proposed in Australia, Portugal, Israel, Ireland, Denmark, France and New Zealand. In other areas such as in Japan, Germany and in states of US like California and Hawaii, pilot programs have already been introduced. Spain is planning to progress with pilot programs in 2012. The U.S, Obama’s administration is steadily promoting plug in hybrid and electric cars to the market – news is expected soon -.

To charge electric vehicles, there are two feasible solutions – a single large electric plug-in engine or several smaller engines placed to each wheel. The use of one engine in the electric vehicles will make the cars more powerful and alike to contemporary cars. However, they have a downfall, related to its inefficient reaction to friction.

The electric vehicles could have engines in the tires. This would reduce the loss of energy (friction) in respect to the single engine solution. Unfortunately, several small engines would only be appropriate for small cars as larger vehicles need more power and thus a larger engine.

The problem of electric cars might come in the motivation to transform and redefine the way these cars are re-filled. Instead of recharging cars for hours, the batteries could simply be changed. It would practically take the same degree of time to change a battery to that of re-fuelling.

The focus is to provide low battery costs. One solution is to provide batteries at a monthly fee or even the car itself for a periodic fee. This would make the car industry alike to that of the phone market. Vehicles could be purchased cheaply in this way. Battery charging, maintenance, replacement infrastructure and support would be provided for a monthly fee.

On average in Europe approximately 12,000 Euros are spent to buy a car and 30,000 Litres of fuel are needed over a year. This brings the cost to roughly 30,000 to 35,000 Euros per year. Research suggests that fuel is three times as expensive as the car itself. On the other hand, an electric car battery would merely cost 7,000 Euros. The electricity cost of charging the battery would amount to 2,000 during the operation life of the battery. In other words, it is only 30 percent of the cost of fuel consumed by typical cars.

In addition, the cost of electricity from renewable sources of energy and battery tend to fall year on year. This mean that the cost of electric cars will experience a diminishing cost in all it senses – the vehicle, electricity and batteries –

For an electric car to drive 100 kms, it will need roughly 10 to 20 kilowatt hour. This is tantamount to 2 Euros. A gasoline or diesel car would make this distance at the cost of 8 Euros. This makes electric vehicles extremely competitive. The only drawback is the high fixed cost of the battery. In order, to deal with these problems formulas used in the cellular phone sector, is currently a competitive option. The battery could be leased similarly to subscription to various phone networks or internet packages. The battery companies will then only change battery at the re-charging stations.

The introduction of electric cars needs a new environment. The solutions lie in either battery replacement stations or charging spots on parking areas (near to cars). Unfortunately, these things aren’t available yet. The transport electrification plans need to be introduced effectively to make sure that the market for electric cars strives.

Strong collaboration between manufacturers and governments are fundamental. Countries like Australia, Iceland, Portugal, Ireland, Denmark, Israel, and in the U.S. San Francisco and Hawaii are taking critical steps. Besides, pilot projects are steadily progressing on countries like UK, France, China, Italy and Germany.
