National Day holiday
Self-driving travel is becoming more and more popular
New energy self-driving travel reaches its peak
From 0:00 on October 1 to 24:00 on October 3, through statistical analysis of 62,700 highway charging facilities (guns) included in the national charging facility monitoring service platform, the total number of new energy vehicle charging times on national highways in the three days before the National Day holiday this year 2.9686 million times, an average of 989,500 times a day, an increase of 48.41% over the same period during the National Day holiday last year; the charging capacity reached 71.6193 million kilowatt hours, an average of 23.8731 million kilowatt hours per day, an increase of 49.39% over the same period during the National Day holiday last year.
Long queues for charging new energy vehicles have appeared in many high-speed service areas across the country. Some high-speed service areas have introduced new regulations that require charging to 80% and forcing them to leave.
So, will it have any impact if the new energy vehicle battery is only charged to 80%?
State Grid experts give answers

Charge 80%
Will not affect new energy vehicle batteries
Qin Jian, director of the charging service center of State Grid Smart Internet of Vehicles Technology Co., Ltd., said that at present, electric vehicles basically use lithium batteries, and lithium battery charging is divided into two stages.
0 to 80% is an efficient fast charging stage, with fast charging speed and stable power. After the battery reaches 80%, it will enter the trickle slow charging mode.
The charging time for the remaining 20% of the battery is basically the same as the charging time for the first 80%, which consumes a lot of pile resources.
During peak charging hours, "eight-point full" replenishment makes the battery safe and saves time; during off-peak hours, car owners can still fully charge the battery normally. Plan routes in advance, charge at staggered peak times, and don’t wait until the battery is too low before looking for a service area.
How to effectively avoid waiting in line at charging stations and improve travel efficiency?

According to the forecast of the Ministry of Transport, the overall charging demand on highways is characterized by "dispersion on the outbound journey and concentration on the return journey".
Starting from 10 o'clock every day, the number of vehicles at the charging station in the expressway service area begins to increase significantly. After 21 o'clock, the traffic flow gradually decreases, and the charging demand decreases accordingly.
October 5th and 6th are the core periods for return journeys, and there will be a significant increase in highway charging vehicles. The peak charging hours are from 11:00 to 21:00 on October 5 and from 10:00 to 22:00 on October 6.
The Ministry of Transport also conducted research and analysis in advance based on the data of the Internet of Vehicles platform over the years, and established a list of particularly busy charging service areas before the Mid-Autumn Festival and National Day holidays. In these service areas, mobile charging equipment, high-power fast charging equipment, etc. were added to alleviate charging needs.
High-speed service areas that are particularly busy with charging across the country include:
Laeting service area and Tanghai service area in Hebei section of Qinbin Expressway;
Pengcheng Service Area, Jiangsu Section of Lianhuo Expressway;
Yundan parking area in Fujian section of Shenhai Expressway;
Xiucun Service Area, Fujian Section of Shaxia Expressway;
Luohe Service Area, Henan Section of Beijing-Hong Kong-Macao Expressway;
Wangwushan Service Area, Henan Section of Hebao Expressway;
Qiaotou River Service Area, Hunan Section of Changzhi Expressway;
Xin'an Service Area, Sichuan Section of Beijing-Kunming Expressway;
Chengcheng service area of Shaanxi section of Beijing-Kunming Expressway.
Car owners can also check the idle status of charging piles in real time through the ‘e Road Smooth’ applet.
The charging problem has been solved, but safety cannot be ignored. Choose a charging pile that meets national standards. Car owners should pay attention to the status of the vehicle when charging and standardize operations to avoid the risk of high battery temperature.
6 taboos for charging new energy vehicles
Avoid risks and extend battery life
1. Do not charge immediately after high temperature exposure.
After being exposed to the sun for a long time, the temperature of the power box rises, causing the battery temperature to rise and charging immediately, which will accelerate the aging and damage of the wiring in the car.
2. Do not charge during thunderstorms.
When it rains and thunders, be sure not to charge the battery to avoid lightning strikes and cause burning accidents.
3. It is not recommended to use the air conditioner in the car while charging.
Turning on the air conditioner while charging will increase the internal charge load of the battery, accelerate the battery decay of the power battery pack, and reduce the battery life.
4. Do not stay in the car while charging.
During the charging process, there are dangerous factors such as high voltage and high current. Although the probability of accidents is very low, precautions should be taken just in case.
5. Arrange charging and discharging reasonably.
Overcharging, over-discharging and under-charging will shorten the life of the battery to a certain extent. Proper charging and discharging will help 'activate' the battery and extend its service life.
6. Use regular charging equipment
Prioritize the use of original factory or charging piles and charging cables that meet national standards, and avoid using inferior or modified charging equipment. Choose regular operators for public charging piles to ensure that the equipment is well maintained.
reminder
The charging cable is thick and heavy. If the cable is tangled and messy, there is a risk of tripping or rebounding and injuring someone. Be sure to be alert when pulling out the gun.
