What s going on with the increase in mileage on high speeds?

In this case, it is more fuel-efficient to run the car at high speeds, so the driving computer calculates that your current fuel level can run longer distances, so it shows that the mileage increases.

This may be a meter display error, it should be reduced.

After driving for a period of time, this mutual cooperation gradually enters the best situation, the running friction resistance will be reduced, the consumption of gasoline and diesel will also be reduced, and the mileage will be increased. Pay attention to fuel consumption: cruising range = oil tank remaining fuel U002F fuel consumption, the key factor that is very harmful is fuel consumption, the selection value of fuel consumption is not the same, the cruising range obtained is much worse, because the working conditions of the car are different, the fuel consumption of the car is actually changed with the driver's requirements; Comprehensive fuel consumption:

At the factory, you can set a comprehensive fuel consumption, such as measured according to the NEDC working condition as the default value, and after the buyer obtains the vehicle, the fuel consumption can be set in various ways, such as instantaneous and steady-state fuel consumption, the cruising range calculated by using instantaneous fuel consumption will oscillate rapidly, and the cruising range may run longer and longer, and the use of steady-state fuel consumption, the average value of long-term fuel consumption is selected.

The basic principle of the calculation method of mileage is actually quite simple, cruising range = fuel consumption left in the oil tank. The key factor here is very harmful is fuel consumption, the selection value of fuel consumption is not the same, and the cruising range obtained is much worse, because the working conditions of the car are different, and the fuel consumption of the car is actually changed with the driver's requirements, so in fact, the cruising range of the car is prohibited.

However, for the specific engineering project, the dashboard indicates the cruising range, which can give the driver a reference, and has a greater practical significance for specific reference, and the calculated instantaneous fuel consumption can be used as a reference for the driver to make a good choice between rationality and safe driving, and the driver is reminded not to be too rude to speed up and reduce the speed.

At the time of delivery, you can set a comprehensive fuel consumption, such as measured according to the NEDC working conditions, as the default value, and after the buyer obtains the vehicle, the fuel consumption can be set in various ways, such as instantaneous and steady-state fuel consumption, the cruising range calculated by using instantaneous fuel consumption will oscillate rapidly, and the cruising range may run longer and longer, and the use of steady-state fuel consumption, the average fuel consumption value for a long time, the cruising range change will be slowed down, and the specific value can not be reflected.

In this case, it is because your driving needs to get better and better, so the fuel consumption will be reduced and the range will be longer.

This situation means that you have passed the break-in period, after which the engine parts are perfectly fitted and the fuel consumption will drop a little.

Maybe it's because the car needs to be driven often. If you just put it at home, it will only get worse and worse in the car

The cruising range of new energy vehicles running at high speed will decline rapidly, basically falling to 60% of the ideal cruising range, which means that the standard cruising range of this car is usually about 500 kilometersUsually it should run at high speed with a range of more than 400 450 kilometers, and there may be 300 kilometers of endurance left. <>

The main body of new energy vehicles is now electric vehicles, and there is no doubt that electric vehicles rely on what drives the motor, but what is the fatal problem of the motor itself? It is its own rotation speed that directly affects the power consumption. The higher the rotation, the more power is needed, because if it wants to run at a higher speed, the motor must have a higher speed, and this increase in speed comes at the cost of consuming more energy.

The proportion of the increase in the cost of this speed increase is not proportional to the proportion of the speed increase, it is the kind of steep rise. <>

Because the new energy vehicle itself is not designed to run high-speed, because in the case of running high-speed, it may be two or three hundred kilometers a trip, and the total mileage of this car is only 500 kilometers, which is still ideal, and it can be 85% off on urban roads, basically there is no endurance anxiety, one trip is twenty or thirty kilometers, this is no problem, but high-speed is not good. In the process of running at high speed, the car should reach 120 kilometers per hour, and the motor speed of the car should reach at least 6500, or even more than 7000, and this power consumption is increasing rapidly. <>

Basically, new energy vehicles are not used to run high-speed, occasionally once or twice does not matter, the car itself has a cruising range of about 600 kilometers, at least 350 kilometers for a 6% discount, there is no problem with this, the highway service area also has the service of charging, so new energy vehicles are generally not used to run high-speed, but there is no problem if there is really a demand for this. People who run long distances and high speeds are basically fuel vehicles, which are convenient to replenish energy, and then the power is more stable, and there is no anxiety about battery life.

Because the driving speed on the highway is very fast, the consumption of power is also very fast, and the battery reserve of new energy vehicles is relatively small, so the situation of new energy will decline sharply.

Because of the power consumption, high-speed driving consumes more power than usual, which leads to a decrease in cruising range.

To understand why electric vehicles have a shorter range as soon as they get on high speeds, we first need to understand that electric vehicles maintain a high-speed operating mode. Generally speaking, BEVs are single-stage geared motors, like gearboxes with only one "gear". In order to maintain high speeds, BEVs must maintain high RPM.

In this operating state, the battery system operates in a "high discharge" mode, in which much more power is consumed than usual.

In addition, some car owners believe that electric vehicles have high torque, quick response, good acceleration, and various overtaking, cruising at maximum speed. At this point, the vehicle's motor has been running under high loads, there is no deceleration and braking, kinetic energy** is completely useless, and there is no excess energy to drive the generator to charge the battery。The battery only has an output, no input, so the cruising range is shorter than the nominal range.

Therefore, despite the advantages of electric vehicles in terms of acceleration performance, all owners of electric vehicles are advised to avoid driving behaviors as much as possible in order to continue driving.

However, if you're using a car in an urban environment, you can easily handle even one "gear".and maintain a normal cruising range because you don't need to stay at high speed for a long time. Because it saves power at this speed.

In addition to speed, the range of a pure electric vehicle will also have a significant impact on the range in the environment in which it will be used. For example, in winter, if the temperature is very low, the energy released by the battery will be reduced by about 30%, which means that the cruising range will be reduced by more than 30% accordingly. If it's in the summer, the constant high temperature environment will also shorten the life of the battery.

First, the speed exceeds 90 kilometers per hour, the wind resistance increases significantly, and the power consumption increases significantly.

Second, most of the motor tuning is adapted to low-speed, high-speed efficiency is low. Some electric vehicles have already begun to be equipped with two or three gears.

Because pure electric vehicles are faster on the highway, they consume more electricity and have a lower range.

Because a pure electric vehicle cannot withstand long-term high-speed consumption, it consumes a lot of power.

Because at high speeds, its wear is still relatively large, and it will naturally consume more electricity.

This is because the speed of our driving has gone up, so the power needs to be increased, too.

Hello, many parts with most of the operation in a tighter state, the resistance is inevitably slightly larger, after a period of driving, these with the gradual completion of the best state to eliminate lead resistance, the running resistance will be reduced, fuel consumption will also decrease, the driving mileage will also increase. Take it.

Galloping at high speed, the continuous fuel pedal power consumption is very fast, and it is normal for the mileage to drop sharply, if the sleepy service area rests and suspends the power mileage, it will recover some, which is a process of battery relieving recharge, and the cruising range of the general new chain slag energy vehicle logo is a constant mileage!

The wind resistance is large, and the higher the speed, the greater the wind resistance.

Lack of energy. The reasons for the high leakage energy consumption (fuel consumption or electricity consumption) of high-speed driving have been clearly explained in high school physics. Energy consumption corresponds to the amount of work done, the amount of work is equal to the product of distance and traction, when the vehicle is driving at high speed, the internal friction and ground friction force are negligible, and the traction force is about equal to the air resistance, and the air resistance is proportional to the square of the vehicle speed.

In other words, the energy consumption of a speed of 200 is 4 times that of a speed of 100 for the same distance.

The faster the car! The greater the wind resistance, the higher the power consumption!

The wind resistance is too great, and the energy is consumed too quickly.

It's the same with petrol cars, when you exceed 120, the fuel consumption will also increase dramatically.

After driving for a period of time, these parts gradually enter the best state, the running resistance will decrease, the fuel consumption will also decrease, and the driving mileage will increase accordingly. The top five models with energy consumption of about 10 kWh 100 km (i.e. 10 km kWh) are all small cars with a driving range of 200 300 km. The bottom ten models have an energy consumption of about 20kWh 100km (that is, 5km kWh), and most of them are large passenger cars with a driving range of 450 570km.

The battery energy is about 20 30 kWh for small cars and 70 100 kWh for large cars. Of course, installing more batteries increases the driving range, one is to push up the price of the car, usually battery equipment accounts for 40% of the car price. In fact, the price of battery energy increases by about 20,000 yuan for every 10kWh of additional battery energy).

The other is to increase the weight of electric vehicles, and the increase in vehicle weight will inevitably lead to a decrease in driving range, which is actually an increase in the ineffective consumption of electric energy. The extreme case is to go from 10 km per kilowatt-hour to 5 km per kilowatt-hour. Additional Information:

Note: The principle of the calculation formula of cruising range is actually quite simple, cruising range = remaining fuel consumption in the fuel tank. The factor that has a greater impact is fuel consumption, the value of fuel consumption is different, and the cruising range obtained is much worse, due to the different working conditions of the vehicle, the fuel consumption of the vehicle is actually changing with the driver's demand, so in fact, the cruising range of the vehicle is not accurate.

However, for the actual engineering, the instrument shows the cruising range, which can give the driver a reference, and has great practical reference significance, and the calculated instantaneous fuel consumption can be used as a reference for the driver to choose between economy and drivability, reminding the driver not to accelerate and decelerate too roughly. When leaving the factory, you can set a comprehensive fuel consumption, such as measured according to the NEDC working condition, as the initial value, and after the owner gets the car, the setting of fuel consumption can be used in a variety of ways, such as instantaneous and steady-state fuel consumption, the cruising range calculated by instantaneous fuel consumption will jump quickly, and the cruising range may run longer and longer, and the use of steady-state fuel consumption, using a longer time of average fuel consumption value, the cruising range change will be slower, and can not reflect the actual value.
