What factors are associated with EV range?

The range of an electric vehicle is affected by many factors, including "driving habits, vehicle weight, traffic congestion, passenger capacity, weather conditions, battery characteristics, service life", etc. To accurately analyze the cruising range, it is necessary to use big data to analyze the historical data of factors affecting energy consumption, and use deep learning algorithms to analyze the cruising range of the vehicle unit SoC, so as to achieve real-time cruising range evaluation.

<> the last two years, electric vehicles.

As a new energy product, it is deeply loved by people, so what are the factors that affect the electric mileage?

1 battery capacity.

For the same electric vehicle, the battery, as the power source of the electric vehicle, is the fundamental factor affecting the mileage, the larger the battery capacity, the more the battery life, on the contrary, the battery capacity is small, and the mileage is relatively small. Of course, models with large battery capacity** are also relatively high.

2. Temperature influence. For electric vehicles, the working of the battery is greatly affected by temperature, and in the spring and autumn seasons when the temperature is right, the battery is in a better working state, and the cruising range is better than usual. The higher temperature in summer, on the one hand, the battery cooling system needs to play a higher role, and on the other hand, the power consumption will increase after turning on the air conditioner, which leads to the poor battery life performance in summer compared to spring and autumn.

3. Electromechanical systems. For electric vehicles, the electromechanical system realizes the link function of battery, motor, car body and various modules on board, and an excellent electromechanical system can realize the conversion of electric energy into kinetic energy as efficiently as possible, and support the operation of various modules on board, such as: body stability system.

Lighting systems, radar, and much more. It can be said that an excellent electromechanical system can ensure that each combination module can play the best overall effect, realize the efficient use of electric energy, and make the cruising range performance more excellent. This is also the gap between many new energy vehicle brands, the same battery used, the configuration is similar, but the mileage is very different, the reason is largely due to the electromechanical system.

4. Driving habits. Driving habits may affect the cruising range in two ways, on the one hand, driving habits, such as hard acceleration, sudden braking, always-on reading lights and other driving habits will cause a waste of power. On the other hand, it is the habit of driving, and when choosing a route, it is more likely to choose high speed, and when driving at high speed, high speed tends to consume more power.

And try to maintain a constant speed of driving, reduce the power consumption of unnecessary operations, can make the cruising range performance better.

5 charging times. For the battery of electric vehicles, there is a service life, and with the increase in the number of charges, the performance of the battery itself will also be affected, which will be mentioned in many sales when Lao Sen buys a car, do not charge it frequently and repeatedly. This is also why many car companies will have restrictions on the three guarantees of online electric vehicles.

There are too many factors that affect the range of pure electric vehicles, such as the driver's driving skills, the driving speed of the vehicle, the temperature, the road surface, tires and other objective factors, which may affect the results.

Here is a knowledge point: the mileage data (that is, NEDC mileage data) announced by the Ministry of Industry and Information Technology (official) is on the high side.

In reality, the actual mileage of the continuation of the crude and simple voyage must be less than the data released by the Ministry of Industry and Information Technology.

This is because the official test results are measured under the best conditions of the car, such as the best temperature, all electrical appliances on the car are turned off, the vehicle has the least load, etc.

The factors that affect it are the heavy use of electrical equipment, as well as the load of the vehicle, and there are many other factors that affect the mileage, such as the driver's driving technology, tires, vehicle fluid mountain velocity, temperature, and road surface.

The first point that affects the whole factor is the new driving force of the whole car, and the second point is the mileage of the electric range, the most important factor is that it is the electric bend is attacking a function, and there are some problems with the delay.

Pure electric vehicles are noisyThe cruising range is the distance that the electric car runs continuously after a full charge when the battery is fully charged until the electric car stops when the battery is fully charged. Since the battery of an electric vehicle will degrade its performance due to increased use, the range will slowly decrease over time.

How many kilometers a pure electric vehicle can lastAs for how many kilometers the pure liter dismantling god electric vehicle lasts, it depends on the battery parameters of the vehicle, the general lead-acid battery.

The cruising range is about 60 km. The mileage span of lithium battery vehicles ranges from 60-300 kilometers. In addition, factors such as turning on the air conditioner, body weight, and battery wear will also shorten the vehicle's range.

<><First of all, prepare for driving.

Obviously, the weight of the body increases, the power consumption also increases, the coefficient of friction increases, and the power consumption also increases. The car consumes more electricity when fully loaded than when it is unloaded, so reasonable control of the total weight of the body can ensure the long mileage of the car.

Many car users put all kinds of tools and accessories, even a whole box of mineral water, as well as some living and work supplies, outing, camping supplies with a very low frequency of use Zheng Yutong put on the car, every day the car carries so many things to travel, will inevitably increase power consumption. It is recommended that you only put the necessary tools and spare tires on the car, and do not bring other things.

And maintaining normal tire pressure is also crucial. Too high tire pressure will threaten driving safety, and too low tire pressure will increase the friction between the tire and the ground, increase power consumption, and affect the range of the car.

Then there is the temperature, the impact on the tire pressure is also greater, usually pay more attention to the tire pressure changes of the car tires, especially when the weather cools down, to timely refill the car tires.

Secondly, external influences.

Good driving habits are important, as frequent sharp acceleration and deceleration will shorten the car's range. It is recommended to drive at medium and high speeds, and when the weather is hot, close the windows and turn on the air conditioner, which will create a quieter and more comfortable driving environment for yourself.

Third, driving mode.

In economy mode, when the power pedal of the car is pressed, the power response will be slower, in exchange for higher economy, that is, the cruising range.

In Sport mode, the car's dynamic response and acceleration are more aggressive, and the loss is also economy, that is, range.

It is recommended that you choose to drive in normal mode for daily use, so that you can find a balance between economy and power, and the driving experience is also very comfortable.

Fourth, energy-saving mode.

The eco mode is all about increasing the car's range.

The energy-saving mode is suitable for use in congested road sections, and the one-pedal mode can be turned on with one key, and the car will shout to slow down and increase the mileage.

Fifth, it affects power consumption, that is, the configuration of cruising range.

Those technologies and comfort configurations, such as cold air conditioning, hot air conditioning, seat heating and ventilation, as well as position memory, air purification, automatic headlights, audio, etc., will consume power when turned on, which will affect the car's range to varying degrees.

It is recommended that you use these accessories reasonably according to your needs, and try to charge them slowly as much as possible. Before and after winter use, plug in the charging gun to charge and preheat the battery, which will improve the range of the car.

The range of an electric vehicle is related to many factors, such as ambient temperature, tire pressure, wind direction, whether the null switch is on or off, air resistance on the empty body, battery capacity, etc. Pure electric cars don't have engines, so many systems run on electricity.

For example, the air-conditioning system of a pure electric vehicle runs entirely on electricity.

If you turn on the empty key while driving, it will definitely lead to a decrease in range.

BEVs have a lower range than usual in winter because of the electrolyte in the battery.

Relatively low temperatures in winter can lead to poor conductivity of the electrolyte, which can affect the range.

If the tire pressure is too low, the contact area between the tire and the ground will become larger, so the resistance of the key when the car is driving will also increase, which will also lead to a reduction in mileage.

Wind resistance is the same as wind direction. If you drive against the wind, the drag will increase, which will also lead to a decrease in the range.

If the drag coefficient of the body is relatively high, the air resistance when driving is relatively large, which will also reduce the cruising range.

Pure electric vehicles are the trend of the future development of the company. The advantage of this type of car is that it does not need to consume fuel and does not need to emit exhaust gases, which is conducive to protecting the environment.

And there is almost no noise when the motor is running, so the interior of a pure electric car is quieter.

There are many factors that affect the range of an electric vehicle, including the external environment, driving status, and vehicle load. Generally speaking, the cruising range of a new energy vehicle is about 400 kilometers, and some high-performance pure electric vehicles can reach a cruising range of about 600 kilometers. These ranges are not standard, and the exact range depends on the driving conditions of the vehicle itself.

External climatic conditions also have a big impact on the range of an electric vehicle. In cold climates, the charging or discharging efficiency of the batteries used in electric vehicles will be greatly reduced, which will lead to a significant reduction in the range of electric vehicles. Electric vehicles are also equipped with a heater system, but the heater system on an EV is very different from the heater system on a gasoline vehicle.

In winter, when the heater is turned on, the electric energy consumed by the electric car will be accelerated. Therefore, low temperature is the main influencing factor for rushing electric vehicles. In general, electric vehicles have requirements for the load of the car.

If the electric car is always overloaded, it will definitely affect the range of the car, and if Yan Qin judges the weight, it will also shorten the service life of the car battery.

There are too many factors that affect the mileage of pure electric vehicles, such as the driver's driving skills, speed, temperature, road surface, tires and other objective factors, which may affect the results.

There is a knowledge point here: the cruising range data (i.e., NEDC cruising range data) announced by the Ministry of Industry and Information Technology (official) is on the high side. In reality, the actual cruising range is definitely less than the number of sales documents announced by the Ministry of Industry and Information Technology.

Because the official test results are measured under the best conditions in the car, such as the optimal temperature, all electrical appliances in the car are turned off, and the load in the car is minimal.

But when driving in real life, it is certainly impossible for the car to reach the test state.

NEDC is the European endurance test standard, and the full name is "NewEuropeanDrivingCycle". The durability test of electric vehicles in China adopts the NEDC test standard.

At present, China is vigorously promoting new energy vehicles, mainly because of the large number of cars in China, the pollution of automobile exhaust to the environment is very serious, and the consumption of resources (oil) is also very serious. The promotion of new energy vehicles can solve this problem very well.

In fact, this trend is not only in China, but in the whole world.
