Manufacturers say that its electric car can run 600km, in fact, it can only give you 400km, sometimes it may not be enough.
This sentence may be very heartfelt, but it is definitely true. According to the current technical reserves and the analysis of the industrial development situation, the "forced" reduction of electric vehicle endurance is beyond everyone's control.
At present, the only way to approve the endurance standard for electric vehicles is the CLTC standard, which is the endurance test under ideal working conditions. For enterprises, publicizing the maximum mileage under ideal circumstances is conducive to encouraging consumers to buy a car, but from the perspective of consumers, the ideal maximum mileage is for reference only.
The consensus of the industry is that the battery life of electric vehicles should be discounted, just a few discounts.
What's the best discount? We concluded that the 30% discount is the cruising range that can be left for the user, and the remaining 30% of the cruising range, part of which has to cope with various driving conditions, and the other part can not be used at all.
Let's start with the first part, which deals with the mileage of driving conditions.
Rational analysis, CLTC driving mileage on the one hand will not run too fast, on the other hand will not be fully loaded travel, but in the case of daily use, it is inevitable to encounter the situation of running the expressway, but also encounter the situation of full load, while the rapid acceleration, sharp braking this simple and rough driving mode will also have.
Then to deal with these driving conditions, you need to use more mileage.
The other part is the mileage that can not be used, this part is better understood, no one will drive the mileage of the electric vehicle to the last kilometer, conservative analysis of the remaining endurance of less than 80km when you have to find a charging pile, the cost of the electric vehicle is too large, the need for trailer rescue, and the fuel vehicle is completely different, so to ensure that the remaining power is sufficient, is the premise of rational use of the car.
Translate into data and let's analyze it.
If there is an electric vehicle with a calibrated endurance of 600km, then according to the 20% off endurance analysis, in fact, the running empty power may only be able to run 480km, which is a comprehensive data, fast driving, full load driving, etc., and this is in the ideal situation.
480km endurance performance, after running 400km there are 80km left, then you have to find a charging pile.
So the safe use of the situation is that a manufacturer tells you that this electric car can run 600km, you remember that it can actually run 400km, in order not to find trouble for yourself, to put the risk estimate to the maximum, never think about running the battery empty, do not try how high the cost of the trailer.
Remember, electric vehicles call cars when they have electricity, and toss people when they don't have electricity.
If the electric vehicle is placed in an icy and snowy environment, the mileage will decline more seriously, the battery's intolerance to low temperatures and the heating needs of the cockpit will increase the pressure on the battery pack, and it will have to cope with the normal use of components at low temperatures, and also to cope with the heating, music, lights and so on in the car.
The battery pack is so large, the way of replenishment is not flexible at present, so it is necessary to amplify the endurance pressure of the electric vehicle to fundamentally improve the use of the feeling.
To make a suggestion, the characteristics of electric vehicles are destined to be more suitable for cities with milder weather, such as Cities such as Guangzhou and Shenzhen, in fact, electric vehicles are more tolerant, and they also have their own reasons.
