For a long time, China's new energy vehicle power supply scheme "charging mode" and "change electric model". Before 2015, the main is divided into "charge" and "electricity". The former joint byd to southern power grid, the latter to the national grid joint zhongtai car.
In January 2015, the state grid launched a new energy vehicles "the beijing-shanghai line" activities, by baic EV200 composed of pure electric vehicles such as the team from Shanghai, finally, the capital airport recharging well packaged, full use of charging piles with energy supplement only. And media of the personage inside course of study thinks, this marks a national power grid from "in electric mode" officially turned to the "charging mode," also means "charging mode" and has since become the electric car electric power supply scheme of "hero".
But recently, "in the electric model" began to have a tendency to "look up". In October 2016, Beijing ten in power plant put into use. This batch of in power plant by baic, the new energy and new energy to sinopec Shanghai electric, etc. Baic also said that the 2022 Olympic winter games in Beijing - zhangjiakou as node, Beijing new energy to replace the way in pure electric taxi in 50000.
Then, actually filled in electricity which model is more suitable for the present situation of the development of China's new energy vehicles, two modes of behind in addition to technical route are inconsistent, if there are other factors?
Technology has both advantages and disadvantages
Technically, in fact, new energy vehicles "charging mode" and "change electric model" each have advantages and disadvantages.
"In the electric model" simply car is completely separate, with electricity power battery as a gas canisters in circulation in the public domain.
Supporters say, "in electric mode" for new energy cars consumers, convenient "in electric mode". According to the current average battery technology in our country, "charging mode" slow filling condition need eight hours to full of battery, state of quick charge also need nearly half an hour.
"In the electric model", in contrast, technically 3-10 minutes to complete the battery replacement. At the same time, the charge and discharge control of centralized, specialization, which is beneficial to prolong the service life of the battery, the owner doesn't have to worry about battery life and quality.
In addition, the "model" in electricity still can use a late-night mass concentration peak valley power charging, saving energy resources and reduce the charge cost.
The malpractice "and" in current mode, the same is obvious. Industry experts believe:
One is "in electric mode" requires a lot of battery reserves, industry scale is huge, the industrial chain coordination is more difficult, is not conducive to electric cars.
2 it is "in the electric model" need a unified technical standard, including integrated battery manufacturing technology, the standardized construction, energy supply network construction, national smart grid construction, urban planning, vehicle access standards, and a series of problems. But these problems cannot be solved at this stage.
Three is "in electric mode" will increase the instability of the battery connected to the vehicle structure risk, electrode spark plug wear easily play, cause security issues, and frequently carry battery can cause damage to the frame.
Mode of essence is "interests"
Filling in two modes in advantages and disadvantages of each technology but actually the industry on the pros and cons of the argument is not a "technical", but the division of business "interests".
Different from fuel car engine technology, in electric vehicles, batteries and battery management system (BMS) is of the core competitiveness of depot, the two parts occupy a considerable part of electric vehicle manufacturing costs, in some even more than half the total cost of the electric vehicle. The expensive profits brought by the battery become the focus of all parties to pursue.
"Electricity" give priority to the development of the pattern, its essence is the link of power battery business, market-oriented operation. Earlier, state grid in its advocacy of "in electric mode" is "battery operator" role, at the same time is also the biggest power battery purchaser.
According to the national grid planning, "in electric mode" is "make money selling cars don't have to charge the battery, car battery don't have to pay", consumers can save money to replace the battery charging station in the national grid.
So, using the "change electric model", not only the profit by the national power grid and changing battery service, the requirements of automobile manufacturers to cooperate with each other to develop corresponding models. New energy car companies are not willing to them in the new energy vehicles, also don't want to let the state grid above the downstream integration in the form of monopoly, control of electric energy supply, natural generally don't want to do "in electric mode".
New energy car companies adhere to the "charging mode" of the reason is clear: can the independent control of the core technologies such as batteries, to grasp the initiative in the development of new energy vehicles, as well as profits from control of battery technology.
Expert: filling in electricity should choose according to the scene
Although "in electric model" was once under the direction of the state grid to low, but according to China's current power battery technology, "in electric mode" has the advantage of still exist. If you can grab "in electric mode" to solve the pain points, good balance between car companies and operators of profit distribution, electric model "in" now as a supplement, charging mode is very have market prospect.
A lot of the personage inside course of study thinks, "in electric mode" is suitable for taxis, buses and have the team groups such as the user of units, and "charging mode" is suitable for private cars and other retail.
In the field of taxis and buses, operating time is directly related to the value created, although the cost is higher than charging stations in power plants, but under the precondition of high load operation of the taxi, in power stations to taxi quickly replenish energy by charging station can't match.
863 national energy saving and new energy automotive great project management consulting team Wang Binggang once said: "in the use of electric mode in certain environment, such as the electric field of taxi, have run more efficient price advantage. Compared with the current mainstream of charging mode, in electric model has covers an area of smaller, more efficient, cost reductions, etc, can run in the form of a small and exquisite, basically be to see the choice of enterprise and market."
