What does the comprehensive range of electric vehicles mean?

1. Range means the long mileage of gasoline in the fuel tank at economic speed. The range refers to the total mileage that can be continuously driven under the largest fuel reserve of vehicles, ships and other driving vehicles.

2. It refers to the total mileage run when the car's fuel tank is full or the battery is fully charged and can't continue to move at all. In China, the Ministry of Industry and Information Technology adopts the NEDC (NewEuropean DrivingCycle) test standard when testing the comprehensive range of pure electric vehicles.

3. The comprehensive range generally refers to the total mileage traveled when the car's fuel tank is fully charged or the battery is fully charged and can no longer be driven. If this prompt appears on the gasoline car, it means that the excess fuel of the vehicle can only be supplied to the owner for 500km.

New energy vehicle endurance

According to the official introduction of Chang'an Automobile, the range of Yidong new energy vehicles It is 405km, which is the normal level of new energy vehicles. As of November 2019, most of the new energy vehicles on the market have a range of about 400km, which can be applied to most road conditions.

How many kilometers an electric car can run mainly depends on the size of the battery capacity, battery life and energy type of the model. Pure electric vehicles: about 121-715 kilometers, plug-in hybrid vehicles: about 41-1000 kilometers, increase Program car: the range is about 800-1200 kilometers.

NEDC range: 575 kilometers. As Tesla's second car, the most impressive thing about the Model X is its gull wing door and the 9-second 100-kilometer acceleration level close to that of a supercar.

How to understand the range of a car?

Refers to the total number of mileage run when the car's fuel tank is full or the battery is fully charged and can't continue to move at all.In China, the Ministry of Industry and Information Technology adopts the NEDC (NewEuropean DrivingCycle) test standard when testing the comprehensive range of pure electric vehicles.

Generally, it refers to the total mileage run when the car's fuel tank is full or the battery is fully charged, and it is completely impossible to move. For new energy vehicles, the maximum range supported by the battery means that the car relies only on the power in the battery to support the maximum mileage of the car in pure electric mode.

The range of a car refers to the maximum mileage of gasoline in the fuel tank at an economic speed. More information about the mileage is as follows: The mileage can also be called endurance, which refers to the total mileage that cars, ships and other driving tools can drive continuously under the largest fuel reserve.

The range refers to the total mileage that can be driven continuously under the largest fuel reserve and other driving tools such as cars, that is to say, the range of an electric vehicle is the electric vehicle power battery in a fully charged state, and the mileage taken from the beginning to the end of the test specified in the standard. As for the continuation of new energy vehicles It depends on how many kilometers to sail.

The range refers to the total mileage that can be continuously driven by vehicles, ships and other vehicles under the largest fuel reserve. That is to say, the range of an electric vehicle is the mileage taken by the electric vehicle power battery at the beginning of the full state to the end of the standard test.

How to make electric vehicles last longer?

1, the power of an electric vehicle is fixed. We can improve the actual endurance by changing the driving mode, such as avoiding frequent acceleration and deceleration; trying to maintain a uniform speed at a speed of 60~80 kilometers per hour, especially do not run the highest speed of the electric vehicle, which is the most power-consuming; the lowest speed It is also not advisable to drive.

2. The endurance of pure electric vehicles is one of the most concerned issues for consumers when choosing pure electric vehicles at present. At present, pure electric vehicles generally adopt ternary lithium batteries, lithium iron phosphate batteries and other technologies. These batteries have the advantages of high energy density, long life and high safety, but there are also problems of small capacity and short range.

3. Therefore, in addition to the high-profile national six cars, electric vehicles have also become the focus recently.However, the range of electric vehicles has been criticized. Although major car manufacturers try their best to promote how high the range of their models is, it is really surprising that the range tends to shrink from the feedback of car enthusiasts. The reason is very simple.

4. The first move is to "miracles", which directly expands the battery capacity and increases the range. The easiest way to improve the range is to plug in a large-capacity battery. It can be larger in volume or with higher energy density. The second is the choice of electric motor.

5. How to improve the endurance of electric vehicles, starting from the battery or driving habits? [Endurance] has always been the pain point of electric vehicles, and how to improve the endurance has become the most discussed topic for users.

The electric vehicle with the longest range in the world

CarBuzz has given the six models with the longest actual range. Let's take a look at what they are. Mercedes-Benz EQS is at the bottom of the six models. This luxury brand flagship electric sedan, which starts at 8.1 million yuan, has two versions of 450+ rear-wheel drive and 580 4MATIC four-wheel drive, with an official range of 849km and 720km respectively.

Top BYD Qin Pro EV. NEDC range: 520 kilometers. The range difference between the BYD Qin Pro EV standard version and the high-power high-endurance version is 100 kilometers, and the latter has a range of 520 kilometers.

Electric vehicles with the longest annual range: Lucid Air Dream Edition R, Mercedes EQS 450+AMG Series, Fisk Ocean "Extreme", Tesla Model S, Ford Mustang Mach-E.

The electric vehicle with the longest range - Tesla Model S Maximum range: 579Km Although Faraday's future FF91 advertises a range of up to 700 kilometers, it has not been mass-produced in a day, and there is no real measurement data, so we still reserve a wait-and-see attitude.

The long-range version of Tesla Model 3 Model 3 has a range of 573km. For a period of time, it has been one of the electric vehicles with the longest range on the market, and Model 3 is a cost-effective choice. It is reported that the new generation of Model 3 is coming soon, and the range may increase.

SAIC Chase maxusmifa9 is equipped with a ternary lithium battery of 70.2kwh in Ningde era, which can be charged to 80% of the power in 35 minutes. The range of nedc comprehensive working conditions is 401km, which is the longest endurance 9-seater electric vehicle.

Why is the range of electric vehicles so short?

Insufficient tire pressure: In fuel vehicles, when the tire pressure is insufficient, fuel consumption will increase, and the same is true for new energy vehicles. Insufficient tire pressure requires more electricity to overcome driving resistance, which increases the power consumption of cars and reduces the range of new energy vehicles.

Under the premise of such a heavy load, the battery capacity is not enough, and of course the forward distance of the car body is even more limited.Therefore, if you want to improve the range of electric vehicles, the performance and self-weight of electric vehicle batteries are the first to bear the brnt. Battery system program: The charging and discharging adjustment and management of electric vehicle batteries are basically regulated by the system program.

Therefore, if you want to improve the range of electric vehicles, the performance and dead weight of electric vehicle batteries are the first to bear the brnt.

Battery aging: If the battery of the vehicle is used for too long, the life of the battery will be reduced, thus affecting the range of the vehicle. Insufficient charging: If the charging facilities of the vehicle are not fully utilized, such as excessive charging time or charging too many times, it will also affect the range of the vehicle.

As far as the motor is concerned, the single motor has small power, slow speed, and long range, and dual motor has large power, fast speed, and short range, which has become a problem that many people are entangled in.The braking energy feedback system means that electric vehicles convert the energy during braking into electrical energy and store it in the battery to reduce energy loss.
