Today (February 18) is the first day of the Year of the Dragon, and many people have been on the front line of work, but some people's return is still "far away".
As a popular tourist destination, Hainan during the Spring Festival once again proved its "attractiveness". coincides with the "longest Spring Festival week in history", and millions of tourists have poured into Hainan for the holiday. On the one hand, the return ticket for Hainan continues to rise, approaching 20,000, and it is difficult to find a ticket; On the other hand, tourists who choose to drive cannot buy tickets to leave the island, and some people have to choose to "stay by car".
Why is it difficult for new energy vehicles to leave the island?
Judging from the official ticketing platform Qiongzhou Strait ferry steward, the remaining tickets for fuel vehicles are much more abundant than those for new energy vehicles, and there are many remaining tickets for fuel vehicles and ferry tickets on February 25, while new energy vehicles can only buy tickets for March 4 today, but they have all been sold out.

What makes it so difficult for new energy vehicles to go out of the island?
According to the Hainan Provincial Department of Transportation, since new energy vehicles mainly rely on electric energy to provide kinetic energy, accidents such as spontaneous combustion are easily caused by high temperature exposure or improper charging. Once out of control, it will seriously damage the ship and threaten the lives of the people on board.
In December 2023, the Hainan Provincial Department of Transportation and the Hainan Maritime Safety Administration issued the "Operation Guide for Ro-Ro Transportation of New Energy Vehicles in the Qiongzhou Strait", which stipulates that "after boarding, new energy vehicles should be parked in the loading area of new energy vehicles demarcated on the ship." According to the actual situation of the ship, the number of new energy vehicles carried by the shipping company shall not exceed 10% of the ship's vehicle quota (calculated as a trolley), and the total number shall not exceed 18, and the conversion ratio of electric trucks (buses) and electric passenger cars shall be converted according to 1:3, and the converted quantity shall not exceed the total number of loads. ”
The staff of Xinhaigang and Xiuying Port revealed that how many new energy vehicles can be on each ship depends on the size of the ship, and there are 5 indicators for ordinary ships.
In response to the peak of passenger flow, the relevant units in Haikou said that they will continue to adjust the frequency of special ships for new energy vehicle transportation, and at the same time add temporary parking lots to alleviate the problem of vehicle congestion at the port. The new port has added a "new energy class", three special classes per day (each class of new energy vehicles within 100).
The Haikou Municipal Bureau of Transportation, Port and Shipping issued a notice saying that as of 11 o'clock on February 18, the total number of cars booked out of the island on that day was about 17,200, and about 7,200 cars had been transported out of the island (including 1,400 vehicles from 9 o'clock to 11 o'clock), and about 10,000 cars were reserved to leave the island throughout the day. The waiting depots in the three ports of Haikou are saturated, with about 5,600 vehicles waiting for the ferry in real time, and it is estimated that it will take more than 7 hours to evacuate.
How big are the safety hazards of new energy vehicles?
The difficulty of Hainan new energy vehicles leaving the island not only reflects the difficulties of Hainan travel, but also makes new energy vehicles fall into a "dilemma" again. Why should new energy vehicles be treated differently?
The country has been vigorously developing new energy vehicles for many years, and in 2023, the cumulative retail sales of new energy vehicles have reached 77360,000 units, a year-on-year increase of 362%。This result is not only the support of national policies, but also the recognition of new energy vehicle products by consumers.
In the initial stage of new energy vehicles, there are indeed many spontaneous combustion incidents, but with the advancement of technology, we should also look at new energy vehicles from a new perspective.
In December last year, the Internet joint rumor refutation platform released the article "2023 New Energy Vehicle Industry Rumor Refutation List", which mentioned that "new energy vehicles are easier than oil vehicles" is a rumor. The probability of accidents in new energy vehicles is not higher than that of fuel vehicles. According to the data of the monitoring and management platform of the National Big Data Alliance for New Energy Vehicles, in 2019, the probability of new energy vehicles is 00049%, and the probability of ** has decreased to 0 so far in 20200026%。According to the data released by the relevant departments of the Ministry of Public Security, the annual fire accident rate of traditional fuel vehicles is about 001%-0.02%。Among the causes of new energy vehicle accidents, the spontaneous combustion of power batteries accounts for 31%. With the maturity of battery manufacturing technology and the improvement of vehicle manufacturing level, the probability of spontaneous combustion of new energy vehicles is also decreasing year by year.
It can be seen that in order to improve the safety of new energy vehicles, many power batteries developed by car companies have undergone strict physical performance, electrochemical performance, charge and discharge performance, and thermal tolerance.
In addition, based on intelligent technology, new energy vehicles are equipped with an advanced battery management system (BMS), which can monitor and control the battery in real time. The BMS will monitor the temperature, voltage, current and other parameters of the battery, and take timely measures when abnormal conditions are found, such as cutting off the power supply, reducing the charging and discharging rate, etc., to avoid problems such as overheating, overcharging or overdischarging the battery. This can greatly reduce the probability of battery accidents and improve the safety performance of new energy vehicles.
It is understandable that the introduction of relevant policies is for the maximum safety of people and goods, but it is also believed that new energy vehicles are constantly optimizing product performance and striving to meet the needs of policies and consumers.
Finally, to borrow the opinion of Cui Dongshu, Secretary-General of the Passenger Association: "New energy vehicles are the only way for China to become stronger. The world's new energy vehicles are a huge driving force to change the world, and this trend is irreversible, non-stagnant, and a huge driving force to change human life. ”
