With the temperature falling everywhere, the "mileage anxiety" of some new energy vehicle owners has become more serious. The mileage is shrinking, the battery is not charged enough, and the warm air is not dare to open... These old and difficult problems still plague many car owners. Some new energy car owners even get up at four o'clock in the morning to grab the charging pile.
How difficult is it to charge new energy vehicles in winter?
Charging is all about grabbing
At eleven o'clock in the evening,
Lao Zhang, a new energy vehicle owner in Niulan Town, Shunyi, Beijing
I went to this charging station near my home to find a parking space.
He told reporters,
Since parking here is free,
Plus 11 o'clock in the night to 7 o'clock in the morning is the trough period of electricity prices,
Each kWh of electricity is about 6 cents cheaper than at the peak of the wave,
Make here 10 charging piles
Become a target for nearby car owners.
"In the winter, the charging time is long, many people live near here, do not go, sometimes there is no place I will leave, the next morning again."
11 a.m.,
Located in the underground parking lot of an office building in Liangmaqiao, Beijing,
The 10 charging piles are also at full capacity.
Mr. Li is one of the earliest new energy vehicle owners in Beijing.
He is also a part-time ride-hailing driver.
Due to the longer age of the car,
Originally a car that was charged once a day
In winter becomes at least twice a day,
At present, it is difficult to queue up major public charging piles in Beijing
It also made him feel helpless.
It is understood that the current energy supply methods of new energy vehicles are mainly divided into charging and power exchange. With fast-charging piles, it takes about one to two hours for a car to fill, and it only takes a few minutes to change the power, so has the power exchange improved? The reporter came to a substation located in the Red Scarf Bridge of Beijing's East Fourth Ring Road, and at three o'clock in the afternoon, the waiting vehicles here lined up in a long line.
With the increase in the frequency of power exchanges in winter,
The batteries of some substations in Beijing have also been in short supply.
Many car owners can only charge the battery at the replacement power station.
Not enough charging facilities
According to the China Association of Automobile Manufacturers,
In the first three quarters,
The number of new energy vehicles in China reached 6.78 million,
The cumulative number of charging infrastructure in the country is 2.385 million units.
1-11 months,
Sales of new energy vehicles were 2.99 million units,
The increase in charging infrastructure nationwide was 704,000 units.
The growth rate of charging facilities
Far from catching up with the growth rate of new energy vehicles.
According to the data, as of September 2021, the ratio of vehicle piles in China is about 3:1, but the average utilization rate of the entire public charging pile is less than 10%, which is mainly due to the uneven distribution of charging piles.
Experts said that in the early stage, the location of some charging piles and the layout of the construction station were not very reasonable. There are also some problems such as the adaptability of the car and the pile, so it affects the owner's use experience.
How to break the game?
The reporter's investigation learned that the activity of the power battery in the low temperature environment decreased, the net discharge rate of the battery decreased, and the battery capacity was affected, so it was necessary to increase the frequency of charging. So, under the premise that the bottleneck of battery technology cannot be broken through in the short term, is there any other way to solve the charging problem?
Experts said that to solve the problem of public charging piles for new energy vehicles, the key is to strengthen the convenience of charging. Technically, it accelerates the application of high-power charging technology, reduces the charging waiting time, unifies the interface, and improves adaptability. In terms of site selection, reduce the time for car owners to find charging piles, refer to the gas station model around the world, no matter where the owner is, you can find an available charging pile within 5 kilometers, which can improve the average utilization rate of charging piles. In addition, the government and enterprises work together to build and share co-management, in order to truly make new energy vehicles run. Tell me if your car is a new energy vehicle?
