Refuelling vs charging, in the new era, should you choose fuel vehicles or pure electric vehicles?

Release time：2020-08-28   Number of visits：591

Since the promotion of pure electric vehicle, the topic of choosing internal combustion engine or pure electric vehicle has always existed, and the debate between the two sides has been continuous.

From the current mainstream point of view, basically focus on two points. Consumers who insist on using fuel vehicles think that the range and charging of pure electric vehicles are hard to hurt. Although the range of pure electric vehicles is longer and longer, and the charging piles are all over the country, there is still no convenience of traditional fuel vehicles. Consumers who like pure electric vehicles think that pure electric vehicles have incomparable advantages in terms of acceleration, comfort and use cost, and the use experience is completely different from that of traditional fuel vehicles.

In addition, in terms of charging, the state is vigorously promoting the private charging pile and power exchange mode. The convenience of electric vehicles will be better and better in the future. At the same time, the cost and tax allowance of a few cents per kilometer of pure electric vehicles are very delicious.

However, when it comes to the use cost of pure electric vehicles, in our view, this is actually a false proposition. It is undeniable that in daily use, the use cost (including maintenance cost) of pure electric vehicle per kilometer is far lower than that of traditional fuel vehicle. However, the battery pack replacement cost of pure electric vehicles is high, and the value preservation rate is far lower than that of traditional fuel vehicles. The insurance cost of pure electric vehicles is higher than that of traditional fuel vehicles. In terms of comprehensive cost, pure electric vehicles are still higher than fuel vehicles.

Not only that, at present, in addition to BYD Tang Jun EV and other high-end pure electric vehicles, most of the medium and low-end pure electric vehicles are in the high-end. Pure electric car money can be bought in the fuel car positioning higher models, in the level and product experience is also higher. For example, Roewe R er6 with a price of more than 160000, small pure electric SUVs from 159800, Honda VE-1, etc. the price of fuel vehicles can be purchased from medium-sized vehicles or small SUVs. It can be said that the price of pure electric vehicles is not equal to the same level of fuel vehicles.

So at the end of the day, do you prefer an internal combustion engine or a pure electric car? Our point of view is that if you or your family only have one car and there are no restrictions on purchase and travel in the city where you live, we prefer to choose fuel vehicles because they are more balanced and mature product force is more suitable for rigid demand. If you already have an additional fuel vehicle, you can choose to purchase a pure electric vehicle as a daily transportation tool. The mainstream household compact class is enough.

Distinction of connector, connector and terminal
1、 First of all, distinguish the concept of "connector", "terminal" and "connector"
① Connector, or connector. Also called connector. It is a kind of component that electronic engineering technicians often contact. Also known as connectors, plugs and sockets. Generally refers to electrical connector. It is a device connecting two active devices to transmit current or signal.
② Connector is a kind of positioning joint connecting electronic circuit, which is composed of two parts, namely plug-in and connector. In general, they can be completely separated. The similarities between switch and connector lie in the change of contact state of their contact pairs to realize the purpose of conversion of the connected circuit. The essential difference is that the plug-in connector only has two states of insertion and removal, and the switch can be in two states It can realize the circuit conversion on the ontology, but the connector can't realize the transformation on the ontology. The contact pairs of the connector have a fixed corresponding relationship. Therefore, the connector can also be called a connector.
③ Terminal, English name terminal. Is used to achieve electrical connection of a kind of accessories products, industry is divided into the category of connectors. The terminal is used to facilitate the connection of wires. It is actually a piece of metal enclosed in insulating plastic, with holes at both ends, which can be inserted into the wire. Terminals can be divided into wuk terminal, European terminal series, plug-in terminal series, etc.
2、 Distinguish "connector", "terminal" and "connector" from the scope of ownership
① "Connector = connector" is the first category, and the terminal is only one of the "connectors"
What's the difference between a connector and a connector?
Connector is the connection of line to line; connector is the connection between line and board and box. In real life, people often refer to the same thing vaguely.
② The terminal is part of the connector. Connector is a general term. In fact, the common connector we usually see includes two parts: the housing and the terminal. Housing is mostly plastic and plays a protective role, while terminal is a metal, which plays a general role.

Several modes of electric vehicle charging gun

Electric vehicle is our favorite means of transportation, for us, the car is our convenient channel. Do you know more about electric vehicles? For you guys, we should be familiar with electric vehicles! After all, the development of electric vehicles is getting better and better. Today, I will tell you about several modes of electric vehicle charging gun.

1、 Use the pulegu household portable charging gun and directly insert it into the 220 V 16A household electric socket. After the automatic safety detection of the charging gun, it can be directly inserted into the electric vehicle for charging, without the need for additional installation of charging pile.

2、 Use pulegu household AC charging pile, directly connected to the 220 V household electricity, and then through the card payment, card charging, direct charging and other ways, you do not need to go to the State Grid to apply for electricity meters.

3、 Go directly to the public DC charging point outside for charging. This charging method can charge 80% within 30 minutes, and can basically be fully charged within 1 hour. However, you need to use the map software to find the public charging point for charging.

Energy saving and environmental protection of electric vehicles has become an inevitable trend in the automotive industry. However, while car companies in various countries are devoting themselves to the development of electric vehicle technology, the charging standard of electric vehicles is also an important factor affecting its popularization. With the increasing support of electric vehicles in various countries, the construction of charging stations is also more and more. Automobile enterprises in various countries have gradually realized that "standard" is the key factor affecting the development prospect of electric vehicles. The small editor of kestar is here to sort out the five major charging connector standards of electric vehicle charging pile in the current market.

The charging pile and the construction method of charging gun for new energy electric vehicle

In the existing technology, the power connection between the charging pile and the electric vehicle is realized through the charging gun. Generally, the gun head of the charging gun is designed with a handle for holding and pinching. Therefore, the gun head of the whole charging gun is large in volume and heavy in weight. The charging gun is inserted into the fixed slot of the charging pile head and is supported by the gun head of the charging gun, so the burden of the gun head of the charging gun is relatively large.

In addition, if the fixed part of the charging gun head is firmly inserted into the gun head fixing groove, it is easy to cause the gun head to fall to the ground, and the charging gun head has poor sealing performance and poor water resistance after being inserted into the gun head fixing groove.

In addition, if someone steps on or pulls the connecting wire at the interface between the charging gun and the connecting wire, the end of the connection will be cracked. This is the most vulnerable place to be damaged, regardless of any charging line.

Charging network problems may drag down the electric car boom in Europe

If you're on a long journey, 150 miles on the road, and start looking for a charging station, you want the nearest charging station to belong to the charging network that you have registered, otherwise you will continue to complete the regular registration process. There are many different power suppliers in Europe, so unless you drive a Tesla with a huge charging network, the chances of finding the right charging station are like buying a lottery ticket, and you need to carefully verify each charging point.

The owners of these charging stations acknowledge that there is a problem and claim that they are doing everything possible to solve the problem, but obviously there is still a lot to do. It's not clear why these charging stations don't have charging piles that only need to swipe credit cards.

AA, the British car rescue group, said the British government had sought to persuade charging station operators to rationalize their systems.

"We need universal, simple and contactless charging networks to make it easier for electric car owners to operate," said Edmund King, President of AA. Early adopters of electric vehicles were not too worried about different charging mechanisms, which is changing as electric vehicles become mainstream. "

King said the British government has hinted that it wants charging companies to provide "roaming solutions" across the entire charging network, so that ev users can use different charging point networks through a single payment method instead of using different smartphone applications.

Professor Stefan bratzel, head of the German car management centre (CAM), said the same problems existed throughout Europe.

Bratzel said there are many charging station service providers in Europe, they need to communicate with each other and make common agreements, and they need some kind of alarm system to show the unusable charging points; in order to avoid unfair charges, and to ensure price transparency, Germany and other European countries must improve on these aspects.

Bratzel said he believes this is the most important challenge facing the popularization of electric vehicles, and as the sales of electric vehicles increase, the problem will become more and more obvious, and if not properly solved, it may have adverse effects on electric vehicle travel. He thinks it will take two to three years to solve the problem completely.

David Bailey, a professor of Business Economics at Birmingham Business School, who also owns an electric car, says that if owners plan to travel long distances, they need to plan ahead to make sure they can recharge properly on the way.

Bailey said the British government should have insisted on universal charging devices, but he was not sure when that would happen. Now there are about eight to 10 different charging networks in the UK. He has a mobile phone with a variety of charging applications and a wallet with various cards, which is very inconvenient for new electric car drivers.

Is this another reason not to buy electric cars?

According to Matt Schmidt, an analyst working in Berlin, in the first half of 2020, the Western European battery powered vehicle market grew by 34.3% in the first half of 2020 compared with the same period in 2019, and the number of vehicles increased to 215711, with a market share of 4.7%. Schmidt predicts that sales of electric vehicles will reach 556000 this year, slightly higher than 1 million in 2021, 1.25 million in 2024 and 1.6 million in 2025.
