The May Day holiday is coming soon, and in two weeks there will be a new wave of travel peaks! For electric vehicle owners, if you want to travel long distances during the long holiday, it may be a bit of a headache.
During the National Day holiday last year, electric vehicle travel, 4 hours of charging 3 hours or charging 1 hour of queuing for 4 hours such hot searches abound, so that people "talk about electricity fear", so that near the Spring Festival, the article on how to plan the route for the New Year when various electric vehicle owners on the Internet went home for the New Year was also a large piece.
It shows that the long-distance driving of electric vehicle owners is sad, the mileage anxiety, and the charging anxiety are like shadows.
Some people say that after carefully planning the route before traveling, there is no worries. Careful planning of routes includes: understanding the situation of the vehicle's battery, mastering the mileage of their own car; calculating how many times the entire trip needs to be charged; choosing what route to choose according to the distribution plan of the charging pile, and knowing whether the charging pile is available, etc.
To achieve foolproof route planning is also a big head, no wonder some people call electric vehicles "electric dad".
We all know that there are many factors that affect the range of electric vehicles: the temperature of the outdoor air; the style of driving the car; the average driving speed; the type of road is highway, mountain or urban road; the on-board situation; the battery condition; whether the air conditioner or heater needs to be turned on during the driving process; the wear of the tires, and so on.
Although the electric vehicle will display the value of the range, this value is a simulated value tested according to the standard working conditions, and does not include these complex factors, so the difference is very large and the reference significance is not large.
Plan your own route, the real mileage prediction relies on experience points, but experience can not withstand the emergence of unexpected situations.
However, now it is 2022, artificial intelligence is so powerful today, driving a car is still afraid of the tail, careful calculation, no reason.
In addition to the development of battery technology to improve the endurance of electric vehicles, and then eliminate mileage anxiety, scientists are also developing a system, the use of artificial intelligence to end the various anxieties of electric vehicle travel, the above careful calculation to artificial intelligence to deal with, the owner only needs to follow the system prompts to drive safely.
First of all, R & D personnel have to collect a large amount of data, the more complex the data, the more accurate the results, and then the data is analyzed and learned by artificial intelligence, through training models, so that artificial intelligence has accurate prediction ability.
When scientists used data sets to train artificial intelligence, although the results were more accurate, they could not be accurate to different models, and recently Mack Trucks, a car company in the United States, released a powerful system they newly developed to help electric vehicle owners accurately plan their travel routes.
The system includes several calculation tools that provide suitable route predictions for different vehicle models, allowing car owners to plan and build their own driving routes based on many variables of a particular route.
First of all, its mileage calculation tool will consider the battery capacity, vehicle application type, ambient temperature, terrain and the number of stops on a specific route and other comprehensive factors to calculate the accurate vehicle mileage, so that the owner can understand the endurance of his vehicle.
Second, the system also takes into account the increased payload, regenerative braking, and the time it takes to stop each stop, updating the data in real time and generating detailed reports that predict the number of starts and stops that can be completed on a particular route.
For the planning of the trip, just enter the location, it can provide multiple routes for the owner to choose according to the predicted mileage and the map distribution of the charging station, and all the data is updated in real time, eliminating the owner's worries.
We have used the navigation system to drive and know that as long as the location is entered, the navigation will give several routes to choose from, each route will show what the predicted time to reach the destination is, if the route is changed or an unexpected situation is encountered, the navigation will update the time of arrival at the destination in real time, and often the prediction of this time is very accurate.
Somewhat similar to the navigation system's prediction of the vehicle's arrival time at the destination, this electric vehicle travel route planning system predicts the mileage, updates the mileage in real time, and accurate prediction can make the owner know what to expect, not to be anxious.
At present, many applications developed on the market to predict the range of electric vehicles are only a rough value, and the prediction system after powerful and complex artificial intelligence calculations is often more accurate, in the future, we will see more and more applications that accurately predict the mileage of electric vehicles, which will be as common as the current navigation system, so that electric vehicles can travel without worries.
