As the Chinese New Year is approaching, I believe many people will drive back to their hometowns to celebrate the New Year, but for pure electric car owners, this is really a headache. I only accept it for long distances, but I go hard in urban areas. This is about pure electric cars, especially in winter. Battery life anxiety will be further amplified. Although our high-speed charging network coverage is already very high, reduced battery life and tight charging spaces are inevitable challenges during driving. However, as long as we plan well, we can run long distances home on pure electric power. Chinese New Year is really not a false proposition!
1. How to plan before departure?
First of all, as a pure electric car owner, you naturally have to know the endurance of your car in winter. Many media and institutions have already conducted winter endurance tests, which basically cover many current mainstream pure electric models. We can answer the questions according to

Although our high-speed charging network coverage is already very high, reduced battery life and tight charging spaces are inevitable challenges during driving. However, as long as we plan well, we can run long distances home on pure electric power. Chinese New Year is really not a false proposition!
1. How to plan before departure?
First of all, as a pure electric car owner, you naturally have to know the endurance of your car in winter. Many media and institutions have already conducted winter endurance tests, which basically cover many current mainstream pure electric models. We can answer the questions according to our own Check the approximate temperature on the road at home to see the battery life of your car model in this temperature range. Generally speaking, if you are in a cold northern zone, the battery life is usually about 50% off. If you are in the southern area where it is not so cold, the battery life is usually 50% off. About 20% off.
After you have an idea of your car’s winter battery life, it’s time to plan your route. How many places can you charge along the way? When and where should I go to recharge? If you had to search and organize all this by yourself, it would indeed be a big workload. However, there are already many map softwares that support automatic planning, and some third-party maps have corresponding new energy modes.
Take the route that the author and his family drove from Dalian to Harbin a while ago as an example. After inputting the starting and ending points, and then filling in the pure electric cruising range of your car and the remaining cruising range at the time of departure, the software will automatically help you plan the route. The number and information of charging stations, as well as the timing of recharging, are all clearly planned for you. It can be said that it saves you a lot of trouble in planning. If you need to adjust, you only need to manually add passing points.
2. What can I do to save more power?
Since we all know that pure electric cars have battery life anxiety when running long distances, then how to save power as much as possible is a homework. First of all, before departure, we need to fully charge the battery. Then when preparing the car and need to turn on the air conditioner and preheat the battery in advance, we can appropriately shorten the remote control operation time and lower the air conditioner temperature. It is also recommended to use the heating and steering wheel heating functions for heating in the car. to assist with heating, or wear more clothes to reduce reliance on air conditioning for heating.
At the same time, we must remember to check the tire pressure in advance. The tire pressure of the car will affect the contact area between the tire and the ground. When the tire pressure is insufficient, the contact area increases, and the vehicle needs to overcome greater rolling resistance when driving, thereby increasing the electric power. consumption, which will be further amplified when driving at high speeds.
Therefore, we can increase the tire pressure appropriately, which can reduce the contact area between the tire and the ground and reduce rolling resistance. In winter, due to the principle of cold expansion and contraction, it can be appropriately increased compared to the normal state.For tire pressures of 0.1-0.2bar, it is recommended to use a tire pressure value of 2.5-2.7bar to maintain relatively optimal driving energy consumption.
Generally speaking, our energy consumption is mainly affected by temperature and speed. We cannot change the ambient temperature, but we can artificially control the speed of the vehicle. It is recommended not to run against the speed limit throughout the process, and control the average speed atAround 100-110.
Moreover, many pure electric vehicles currently have high-speed driving assistance and intelligent driving experience. If your car supports such functions, you can turn them on for a period of time when the road conditions are good, which will not only greatly reduce the risk of It can also control the vehicle speed more accurately when driving due to fatigue, maintain the vehicle speed in a relatively stable and economical range, and automatically adjust the speed according to the traffic flow, making better use of kinetic energy recovery and reducing the increase in energy consumption caused by speed fluctuations.
3. What should you pay attention to while driving?
What we have to do while driving is to adapt to circumstances. Although we have already had map software to help us make charging plans before, as the saying goes:"The plan cannot keep up with the changes!", such as the charging locations in the service area are full, traffic accidents, traffic jams, etc., then at this time, we need to make adjustments to our charging plan.
It is generally recommended to drive one on the wayMore than 200 to 300 kilometers, or when the battery drops to 20%-30%, you can add waypoints on the navigation and go to the nearest rechargeable service area to recharge. If the charging slot is full and you need to queue for a long time, we can also Get off the highway and find a nearby charging station to charge. Generally, the charging spots will be more abundant than in the service area, and the charging speed is often faster.
At the same time, when charging, we try to charge and discharge shallowly, charging from the remaining power to When the battery reaches a little more than 80%, you can pull out the gun and leave. This ensures that there is enough power to continue driving, and the charging time is also short, which is also good for the health of the battery. After a good rest, we can set off.
Of course, if you encounter an unexpected situation, you can plan in advance appropriately. When the power drops to When the battery reaches about 30%-40%, you can plan the next charging location. At the same time, if you encounter an unexpected situation and break down, don’t worry too much. Remember to call for roadside assistance. During the Spring Festival, many brands will provide free roadside assistance and Car delivery service to other places to ensure everyone’s car travel.
Summarize:
The above author has summarized some things that need to be paid attention to when traveling long distances by pure electric train back home. In fact, for people who use electric trains for a long time, although there will be some anxiety about battery life, as long as they make good plans and run long distances, there is no big problem, and it is also It can save a lot of money. I believe that many people will start their journey back home in a few days. I wish all car owners can travel safely and go home to have a happy and happy New Year.
