In recent years, with the rapid growth of electric vehicle ownership and the improvement of the endurance of pure electric vehicles (BEVs), it has become more and more common to drive electric vehicles back to their hometowns and travel. However, the peak travel of holidays, the imbalance between supply and demand of charging piles in the service area is still widespread, the picture of car owners competing for charging piles is still fresh in people's minds, the scene of charging such as long queues of electric vehicles is not uncommon, and the problem of "charging difficulties" of electric vehicles on holiday highways is becoming increasingly prominent. How to economically and reasonably solve the contradiction between the low utilization rate of high-speed charging facilities and the explosive growth of holiday charging has become a social problem that needs to be solved urgently.
During this year's Qingming Festival holiday, the charging vehicles in the highway service area were full, and the queue had been lined up outside the service area
Emergency charging chamber as an emergency means to alleviate charging anxiety

During this year's Spring Festival, the first movable emergency charging cabin in China appeared in the Dongping service area of The Jinan-Guangzhou Expressway in Tai'an, Shandong. The emergency charging chamber is about the size of a standard container, the single cabin is equipped with 360kW charging cabinet and 6 charging interfaces, and the maximum output power of a single gun is 180kW, which can be 50% more efficient than high-speed ordinary chargers. On the basis of the charging pile service already built in the service area, it can also meet the charging needs of 6 electric vehicles at the same time.
"Emergency charging chamber" to solve the main emergency vehicle charging needs, its application scenarios in addition to high-speed service areas, but also in popular attractions, large-scale activities and other occasions to use. During non-holiday periods, the charging chamber can also be moved to locations such as high-heat charging stations in urban areas, and can also be used as temporary piles to meet the charging needs of important customers.
G60 Shanghai-Kunming Expressway Quzhou service area emergency charging cabin
State Grid Shandong Electric Power plans to deploy 1 "emergency charging chamber" in each of the 10 high-speed service areas in Jinan, Qingdao, Zibo, Weifang, Jining and other places, and open for operation before the "May Day" holiday this year. It is reported that at present, many domestic high-speed service areas such as the G60 Shanghai-Kunming Expressway Quzhou Service Area and the Beijing-Hong Kong-Macao Expressway Leiyang Service Area have been put into emergency charging cabins to facilitate long-distance travel on holidays.
These emergency charging cabins are operated by State Grid electric vehicles, and car owners can scan codes for charging and settlement through the "e charging" mini program. It should be reminded that these emergency charging piles can not be displayed on the "e charging" mini program, and the BEV owners who need to be charged are best to take a look at it when passing through the above service area, and there may be an empty charging gun waiting for you.
Infrastructure construction is still far from catching up with the growth rate of BEV, and the best way is not to drive BEV out of the door. So, if you have to travel long-distance holidays with BEV, what other ways can you alleviate charging anxiety? The following Xiaobian combined with his own practical experience with netizens, summarized a few points that can effectively alleviate the anxiety of long-distance charging on holidays.
Avoid high-speed charging spikes
According to big data statistics, in fact, the charging peak of the high-speed service area is regular. The State Grid Electric Vehicle Service Company and AutoNavi Map have compiled a national high-speed charging peak forecast for everyone, so that everyone can reasonably arrange travel time to avoid charging peaks.
Charge at high speed

Due to the limited resources in the highway service area, it is impossible to meet the simultaneous charging of a large number of electric vehicles, but when the charging pile in the service area is tight, the owner can also make full use of the charging pile near the entrance and exit of the highway to briefly leave the highway and replenish the energy.
Taking the Beijing-Hong Kong-Macao Expressway Leiyang Service Area (Hong Kong and Macao direction) as an example, there are 7 public charging stations within 10 kilometers nearby, and the farthest New Energy Charging Station of Leiyang Yuemao Wuli Brand is only 11 kilometers, where there are 7 piles and 14 fast charging guns, which can basically be charged with it.
Try to choose a charging pile that can be used exclusively
The general fast charging pile is equipped with two charging guns, similar to the number 1A, 1B, these two guns are shared with the power of the No. 1 fast charging pile, for example, a 120kW fast charging pile two guns charged at the same time, then a single only 60kW maximum power, but only one gun can be charged when you can enjoy this 120kW exclusively. Therefore, if you have a choice, try to choose a charging pile that can be used exclusively to charge, so that the efficiency of charging will be much faster and save a lot of time.
BeV speed should not exceed 100km/h
In general, the slower the speed of electric vehicles, the more power-efficient they are. Taking Tesla, which has better system efficiency, as an example, the actual measured Model X has a speed of 60km/h cruising, and the actual driving mileage is about 90% of the nominal mileage; while cruising at 100km/h, the actual driving mileage is about 80% of the nominal. Once the speed exceeds 100km/h, the battery pack needs to increase the current in order to ensure power and overcome air resistance, and the power consumption will become higher and higher with the speed. Therefore, when a pure electric vehicle is driving on a high speed, it is best to drive around 100km/h, which can achieve a relatively stable cruising range without affecting the driving of other vehicles.
Try to use Weilai "one-click power-up"
NIO has opened the charging car power-up service, and other electric vehicles that are not NIO brands can add another charging option, and can also enjoy the convenient power-up service of NIO Power.
Open the "Weilai Power Up" Mini Program, select "One-click Power On" and click "Call Power Up" to place an order. After logging in, fill in the relevant service information such as the location of the vehicle, check "Specify charging service car" and select Submit. After confirming that the information is correct, click Pay (380 yuan), you can book a charging service car at a designated location such as the nearby high-speed service area for power-up service.
The maximum power of Weilai's tram system is 90kW, which can reach about 60kW when charging, and a single charge can charge the electric vehicle to more than 90%. Although the price of "one-button power-up" is higher, if you encounter a charging station that waits too long and you are in a hurry to charge, you can still use it as an emergency means.
Finally, although there are many ways to alleviate the anxiety of BEV long-distance charging, our position is that BEV is not suitable for running high-speed long distances on holidays. If you travel long distances on holidays and choose fuel vehicles or plug-in hybrid models, then these anxieties will no longer exist.
