Electric car market grows the whole world trend

The whole world is dynamoelectric car (EV) 14 million when sales volume predicts to the end of 2023 from 3 million of 2020, increase rate is as high as 367% . [All 1] areas have the contribution with differ size to this one amplitude, china ranks front row, the European Union keeps changeless, american share also rises somewhat. 18% what the sales volume of electric 2023 car can take total sales volume, if illuminate this trend development to go down, to 2030 everyday but managing 5 million pails of oil. Graph 1 revealed the flowing index curve that changed car sales volume with the incoming telegram 2016.

The main factor that promotes this one growth includes:

. Batteries engineering capability promotes continuously, to 2030 aux will be able to satisfies the batteries requirement of electric car quite, achieve this fractionize market ” clean 0 discharge ” target

. Recipe of new-style batteries chemistry alleviated material supplies pressure, solved traditional technique to be in the problem of add boat course of development, risk and performance side

. Charge infrastructure continues to raise the requirement with satisfying customer

. The growth of the support of policy and investment, revealed the collaboration of local government and private enterprise in electric car domain

Produce the promotion of speed as the car, the cost of consumer is reduced further, electrification proceed. In addition, of cost reduce still can increase sales volume, the demand that brings for the place of automation market fund of high capitalization also will be quickened. This one trend will reduce the cost of consumer considerably, make electric car makes the product that ordinary people can afford.

Of course also crosscurrent thinks to charge the problem still is met a few customer change block up to electric car, because charge,time grows the change that can bring add boat angst and way of life too.

1.Of current and electric car charge means

Electric car charges foundation

Current most electric car is get energy to undertake charging from existing power source, a lot of among them power source are cannot reborn (be like fossil fuel, coal) . To maintain carbon is counteracted or carbon loses value status, answer the influence that climate change brings, change of the climate between U.N. government is special committee (IPCC) in its ” Sixth Assessment Report ” [intense proposal is used in 2] but second birth the sources of energy.

If charge,infrastructure is used but second birth the sources of energy (pledge like solar energy, wind energy, biology can, water and electricity) , the usability of this kind of the sources of energy and dependability are natural put in a few limitation. But electric car still is the important way that traffic domain realizes carbon to decrease a platoon. Accordingly, industry must be opposite below a few problems give out the answer:

. How does solar energy generate electricity to answer nocturnal occasional cloudy day?

. How is wind report answered blow not the case with the rule or not quite strong wind-force?

. Will but whether can the process of electric energy of translate into of second birth the sources of energy eliminate carbon completely to discharge?

Want to answer these serious questions, with respect to the pattern that must analyse current electrified wire netting to get electric power, and charge for electric car requires condition.

2.Global power source

Be in different area, the power source of trunk electrified wire netting is put in very big difference. Even if is in same a geographical area, the power source of photograph adjacent area also may have distinction. Watch 1 listed the whole world generates electricity circumstance, offerred 2020 to these two years of 2022 change trends between. [3]

Express 1: The whole world generates electricity circumstance, 2020 – 2022

(graph source: Author, data comes from Our World In Data)

Can see from inside the watch:

. Coal still takes dominant place in source of global hair electric energy, but growth rate is putting delay (although what its occupy scale to rise somewhat)

. Natural gas ranks 2, continued 2020 from the trend that keeps balance to drop

. But place of second birth the sources of energy holds proportion not quite, but showed clear growth trend, wind energy and solar energy continue to show exponential level growth with same rate

. Water and electricity tends finally already it seems that smooth

. Raw material also can be a kind of burgeoning the sources of energy, show linear growth

The data that provides from Our World In Data can see, the whole world makes an appointment with the electric power of 39% to come from low carbon the sources of energy, include nuclear energy, raw material to be able to be mixed among them other but second birth the sources of energy. Water and electricity, wind energy and solar energy but 30% what second birth the sources of energy takes global electricenergy production, and the electricenergy production of wind energy and solar energy still is continueing to increase considerably.

Predict 2022 to between 2050, the growth of global power demand will exceed 75% , accordingly, to but the place of change since people’s expectations of second birth the sources of energy returns, also be phasic place needs. [4] and the development of the addition of population and electrification also is aided turned this one tide. Nevertheless, power demand increases to still have a crucial factor is to come from the pressure that changes at climate. Show level, the electric power of global close 2/3 still comes from at fossil fuel, and the dependence that we must reduce pair of fossil fuel, change direction more friendly to climate but second birth the sources of energy.

The electrification current that increases quickly at present can create enormous pressure to electrified wire netting, because charge,the bear of electrified wire netting of fastigium can become bigger, but the memory of second birth the sources of energy also can face bigger challenge. Should alleviate demand increase sharply is right charge the influence of infrastructure, technical innovation is potion effective prescription, and the car is one of these innovation to technology of electrified wire netting, its changeover previously between electrified wire netting and electric car charge direction.

3.What is a car to technology of electrified wire netting?

The car is right electrified wire netting (V2G) the technology can realize the two-way energy between electrified wire netting and car to transmit, will carry easily thereby store can device arrives dispersedly each district, no longer power station of bureau be confined to. The electric power that this technology can carry every electric car on the road passes on electrified wire netting neatly when need in, the electric power that lets be obtained through charging from the net also can be used rise; V2G feasible, because comparative,be quantitative consumer used the one fraction of batteries capacity only; This kind of method can raise batteries utilization rate, let same package produce more beneficial result.

The electric car family expenses of the user charges picket is the infrastructure to electrified wire netting or domestic power supply. Responsible aux will be able to measures the circuit that carries battery from electrified wire netting, can use likewise batteries medium redundant energy loses wire back network, allow an user with market price or negotiate the price to gain income. Using electric demand and usability of the sources of energy to decide energy is get from inside electrified wire netting, still pass on electrified wire netting. This kind of structure offerred a kind to press the way that wants power supply, can save redundant n at the same time rise for be being used in the future.

The production that V2G optimized electric power, use and transmit. Car batteries will with long-range store can solution couplet net, the electric power that enhances pair of electrified wire netting in the fastigium that use phone is carried, charge in the car when (nocturnal occasional uses electric trough period) optimize power supply.

Additional, v2G still can offer concerned car advocate the data that the sources of energy uses a convention, encourage them to come through optimizing them behavior more actively government energy resources is used, reduce a travel cost; In the meantime, car advocate still can sell electrified wire netting electric power, thereby open up a kind of new income source. Those who drop electric car is total have cost, raise its whole world to use one of primary market driving force of rate just about.

In addition, in the electric power data that generates from V2G, we still can be informed car when to be used, when to generate electricity, this also conduces to public utility branch coming to those who optimize this to generate electricity according to trend of effective demand and consumer behavior, reduce the cost of power supply unit and consumer thereby.

V2G still can provide benefit of a society, that is it can let be done not have originally store can the place of establishment is used somewhere else long-range store can establishment. Rise the circumstance using phone of car and correlation of electrified wire netting, what bring a few have revolutionary advantage, depend on can be between car and electrified wire netting store according to needing to undertake to electric power, adjust and supply.

Green is dynamoelectric the car charges use solar battery board, let photon arouse an electron, generation electric current flows to car and fill cell. Generate electricity to the solar energy of intermittence, should make electric power is supplied so that press,keep smooth need to use, a kind of natural way is its and batteries store can be united in wedlock. After batteries fills report, can use these the sources of energy anyplace according to needing to be in, no matter be,still be on board in the home. V2G was solved but the memory difficult problem of second birth the sources of energy, this is to rise but utilization rate of second birth energy one of main challenges of place remnant.

Influence but the other difficulty of utilization rate of second birth energy and obstacle

What one of advantages of electric power depend on it is efficient. Batteries general chemical energy is direct translate into electric energy, avoided to be able to reduce thermal efficiency the fuel combustion of about 30% . V2G is the solution with a kind of clear advantage, can alleviate already but the instability of second birth the sources of energy, can ease pressure of electrified wire netting when power demand increase sharply again. But, want to make electric car walks into an innumberable families, it still must be overcome a few otherer challenge.

Another of V2G introduces the advantage that fix eyes on was to create a kind new but second birth the sources of energy: From the energy that V2G gets. It increased to let energy is flowed into and pour out of the ability of electrified wire netting, make energy more like a kind of money, can transfer between the sources of energy and application.

Current, the car charges with dc picket welcomed development opportunity, the converter that needs to have proper volume comes to alternating current changeover undertake energy is transmitted for dc. Although had had changeover efficiency to be as high as the communication of 95% now – dc converter, but the efficiency that this kind of a lot of products still can achieve 80%-90% only. Accordingly, industry is necessary to come according to the batteries capacity of electric car converter of custom-built power source, and improve changeover efficiency hard, increase power output directly thereby.

Epilogue

But the electric car of drive of second birth energy comes true to passing V2G but the target of second birth electrified wire netting is crucial. This kind of method uses green solar energy to be the batteries of electric car to charge, those who support electric car and electrified wire netting is two-way charge, can carry electric power the place of need.

V2G offers a kind agile store can option, solved but a of second birth the sources of energy main obstacle, alleviated at the same time the instability that wind energy and solar energy generate electricity. V2G technology supplies electric power contact together with consumer demand, provided means of a kind of instant power supply, make an user active participate in come in, it is one kind just is mixed to power supply for consumer the method of efficient, economy.
