Which is the most annoying of battery life and charging?
With the arrival of winter, temperatures have started to drop rapidly. In Jilin and Changchun in the northeast, the temperature has even reached zero. As the temperature plummeted, the friends who opened the pure electric car in the north began to “distracted” for the decline of the cruising range.
Their anxiety has its causes. Some studies have shown that when the temperature drops from 25 ° C to -20 ° C, the amount of electricity that can be released by the car’s power battery will be reduced by 30%, and the charging time will increase accordingly. In fact, however, the current high-end electric vehicles will design a thermal management temperature control system to maintain the operating temperature of the battery, which can inhibit the endurance of the winter, but this will consume some power.
As a friend of the Northeast circle of a friend, his Tesla Model X was about 0 °C when he was on the road in Harbin in the afternoon. He traveled a distance and found that the power consumption increased from 22 degrees to 27 degrees. This situation should be a part of the energy to heat the battery.
However, some industry analysts pointed out that as the new models continue to advance in technology, even in the winter environment, the cruising range is not the biggest problem for the owners. Some market analysis emphasizes that charging is the biggest worry for car owners compared to the pain point of battery life.
This statement is valid?
Car owner’s pain: life? Charging?
To this end, understand the notes and summarize and analyze the current voices with different opinions. Let’s take a look at the data and opinions behind the difficulty of charging and the difficulty of life.
Although the new energy vehicles will have some decline in cruising range in the winter, from the research data of the professional auto media platform “after the car”, it can be found that the current life of some mid-to-high-end new models is not very large. As shown in the following figure: Most mainstream models have a range of more than 200 kilometers in winter.
Among them, the winter cruising range of BYD Song EV500 and Beiqi EU5 is 228~283km respectively. If it is not used for taxi or long distance running, the owner does not need to worry about cruising mileage. So another topic that focuses on the car owners is not affected by the seasons. This is the annoyance of charging.
Charging pain points, is it a real problem for new energy owners?
Let’s take a look at the idea that “lifetime is not a problem”. Relevant analysts believe that the performance of new energy vehicles’ endurance has been more than a year. On the whole, the new models of major brands have been constantly refreshing their records in terms of battery life. After understanding the performance indicators of the new energy vehicles from the first batch to the 23rd batch of the “new energy vehicle model catalogue exempting the vehicle purchase tax”, the paper obtained the endurance of each batch of new energy vehicles. The average of the indicators.
In the figure below, it can be seen that the current mileage of new energy vehicles is increasing linearly. According to the release time of each batch, the cruising ability of new energy vehicles is from the Ministry of Industry and Information Technology and the State Administration of Taxation. The Catalogue of New Energy Vehicles Exempted from Vehicle Purchase Tax, released on August 27, 2014, and the Catalogue of New Energy Vehicles Exempted from Vehicle Purchase Tax, released in the 23rd batch on March 11, 2019, The average mileage of new energy vehicles announced has changed significantly: after four years, new energy vehicles have been running from a lower 150 kilometers, reaching a maximum of 364 kilometers of battery life, an increase of more than 200 kilometers.
Of course, more scientific data is the result of the test method.
Because when driving a new energy vehicle, the driver will turn on the air conditioner and brake. Therefore, the test driving method will be tested by the working condition method (common NEDC condition), but the actual road conditions may be More complicated, many new energy vehicles that promote the driving range of NEDC under the conditions of three or four hundred kilometers may not be able to run that far.
Based on the “Full Full List of China 2019 New Energy Vehicles”, released from the “After the Car” and “Shenzhen”, we can see the analysis of the measured results of the relevant models. From the top ten status of the list, you can find that in addition to the high performance of Tesla Model3, Tesla ModelX, BYD Don EV, Weilai Automobile ES6, GAC New Energy GE3 530, etc. Both are close to or exceed 300 kilometers, of which the suburban working conditions are about 400 kilometers. Therefore, the mileage of new energy vehicles has made great progress.
Where is the actual pain point for urban residents driving?
At present, large and medium-sized cities have problems of long commuting distance and long commuting time. The commuting time not only occupies the time of commuting and living, but also reduces life satisfaction and happiness. Therefore, the city commuting efficiency is right. The core requirements of new energy vehicles are the value of realizing new energy vehicles.
As can be seen from the “Drip Trip 2018 Urban Traffic Travel Report”, Drip Travel analyzes 100 cities with more travel and population, which defines the travel radius and travel radius of these cities. The definition is based on the city center, and more than 90% of the starting or ending points of travel are distributed within the circle with this radius. The top five cities are shown in the table below.
Obviously, Beijing has the largest travel radius, so this article takes the first place in Beijing as an example for more detailed analysis. According to the latest model data released by the Ministry of Industry and Information Technology, the current average mileage of new energy vehicles is 360 kilometers, far greater than 31.7 kilometers, which can meet the traffic demand of Chinese cities. Therefore, this is also pointed out by relevant analysts. In terms of mileage improvement, new energy vehicles are no longer as urgent as when they were only about 100 kilometers in the early days. In particular, the new models launched in the past year and more have already been able to meet the commuting needs of residents in major cities in China.
Understand the notes and summarize the data of “Drip Trip: Q2 Urban Transport Travel Report of 2018”. The correlation between long-distance commuting and regular distance is analyzed. The results are as follows:
The data shows that Beijing’s commuter distance is only 3% when it is more than 60 kilometers away. Therefore, the mid-to-high-end models such as Tesla and Weilai are abandoned, and the conventional models of BYD and BAIC are already available.Meet the normal commute needs of 97% of people on weekdays.
Someone will say what will happen on the highway? In fact, according to Article 62 of the “Regulations on the Implementation of the Road Traffic Safety Law”, driving a motor vehicle continuously for more than 4 hours should be stopped and rested for at least 20 minutes. Therefore, in the high-speed working environment, the four-hour mileage of the new energy vehicle on the highway is difficult to exceed 480 kilometers, because the high speed limit is 120 kilometers.
So under normal circumstances, a new energy vehicle can reach a speed of less than 480 kilometers on the expressway, which can meet the travel needs of most urban residents, because most of the new energy vehicles at this stage are close to this. A level.
In fact, the expressways in first-tier cities such as Beijing and Shanghai are also often traffic jams, especially high-speed travel is mainly concentrated on holidays. According to the data of “Gao De map: Q1 China’s major cities traffic analysis report in 2019”, high-speed traffic jams have occurred, because new energy vehicles are different from fuel vehicles. Under parking conditions, almost no electricity is required, so users The mileage that runs within 4 hours will be shorter, and the fear of driving mileage will be greatly reduced.
The question then comes, why are more and more car owners starting to worry about charging?
The charging pile is difficult to find, and the charging time is serious
Why is it that the most annoying thing for the owner is charging?
First look at the reality of the charging piles with the most scooping in the forum. In order to solve the problem of difficulty in charging new energy vehicles, local governments and car companies have paid a lot of actions and efforts. Relevant industry authorities and leading electric power companies not only promote the construction of charging piles throughout the country, but also constantly research new charging technologies.
However, relying on charging piles to charge new energy vehicles is mainly suitable for owners who usually go to work or travel, but not for owners who need long-distance transportation or taxis.
A Shenzhen taxi driver with 15 years of experience tells me that the new energy taxi has no noise, the ride experience is comfortable, and 100 fuel bills can be saved every day, but the most headache is charging too. inconvenient. “This charging time is too long, affecting our normal work, and we have to try our best to charge during the rest time. Because the charging pile is now charged.It’s a long time. If I usually use the fast charge function, it will take about 30 minutes. The driver said that in the winter, the charging process in many northern cities is also unbearable, and in the long run, fast charging will also cause great loss to the battery.
In addition, even the car owners who usually go to work or live, when they continue to charge, can not be charged as easily as refueling. In particular, many residential properties have begun to strictly manage the problem of random charging of community owners. In addition, charging piles have to be lined up, or occupied by fuel vehicles, causing some owners to temporarily squeeze buses or taxis in time.
At the same time, some new energy vehicle users are also reflecting that both public charging piles in the community and self-use charging piles may be hindered, because many old community power facilities are still unable to meet the charging needs. .
In order to improve the endurance, many new energy vehicles now carry more and more batteries, which means that new energy vehicle batteries need to “absorb” more electricity. Assuming that the charging technology is not improved in time, the time it takes to charge will become more.
In summary, the pain points of new energy vehicles will change in the near future. They may become more sensitive to charging challenges because of the gradual resolution of their cruising range. No matter the lack of charging piles at this stage and the long charging time, more and more car owners will get bored. This kind of problem may put more demands on the future “replacement” market for charging cars. At this stage, more car owners are most concerned about the problem, perhaps who is to solve, how to solve the “charging difficulty”?
Today, many car owners are gradually turning into “owners of new energy vehicles”. In the process of using new energy vehicles, do you agree that charging anxiety is far greater than life-long anxiety?
