The impact of tire pressure on cruising range is often overlooked by people. Take the common two-wheeled transportation tool bicycle as an example. When the bicycle tires are deflated, it is even more difficult to move forward. The reason is simple: if the tire pressure is too low, the contact area between the tire and the road will increase, and the friction will also increase, and it will take more external force to continue moving forward.
The same is true for
new energy vehicles. When the tire pressure is insufficient, the motor will spend more power to overcome greater resistance, so power consumption will increase.
The theory is somewhat hollow, for example. In order to further verify the impact of tire pressure on the cruising range, E Electric Park selected a
changan electric cars for real-time monitoring within two days.
Even in the hot summer, the air conditioner is turned on all the way, and there is still a lot of power left under the condition of high tire pressure. Under the same route and mileage, the test results differ by as much as 34km, which shows the importance of tire pressure to
Changan Electric Cars.
So, is it really feasible to increase the tire pressure blindly to gain cruising range? Not so. For car owners, as long as they often pay attention to the tire pressure, it is enough to maintain it within the standard range. Everything has two sides, too high tire pressure will cause the risk of tire blowout, and too low tire pressure will increase tire wear.
It accounts for 6% to 12% of the total energy consumption of Changan
electric cars. So, in addition to these uncontrollable internal factors, does human driving habits affect the cruising range? The answer is yes.
1. When the car is not hot, it will accelerate rapidly when it is started. Hot car, how hot is the Changan Electric Cars? When seeing this word, many car owners must have the same doubts as me. The hot car of Changan Electric Cars refers to that the Changan Electric Cars should drive slowly and at a constant speed within a few minutes of starting. The reason is that in order to ensure that the battery can operate normally, the coolant needs a gradual warming process. A heated battery will run faster than a cold battery. On the contrary, if the car is not warmed up, the cold battery will consume a lot of electricity after violent driving, and the battery life will be reduced by about 10%-15%.
2. Frequent braking and starting. The reason is simple, similar to traditional car models. In congested road conditions, gasoline vehicles frequently brake and start, and the fuel consumption is also very large. The same is true for Changan Electric Cars. Repeating this action will cause the motor current to rise frequently, which is several times that of normal operation, so it will consume a lot of electricity.
3. Speeding party, accelerate and brake quickly. You must know that most Changan Electric Cars are used for transportation, not sports cars. Car owners who have the habit of speeding must pay attention. When accelerating and braking suddenly, the motor always outputs high power and generates relatively large heat. In addition to consuming more power, it will also affect the service life of the motor. Stepping on the switch hard to accelerate or stepping on the brakes will cause the instantaneous current to be too large, which means that the power consumption is large.
4. Too much load. This is easier to understand. Still the same as traditional cars, the weight and load strength of
Electric Vehicles will also affect the mileage of electric vehicles. The greater the movement resistance, the faster the power consumption.
5. Use windows instead of air conditioners. In order to save cruising range, many new energy car owners have tried this method. This approach does not cause too much loss in daily driving, but if you drive at high speed with the windows open, it will disturb the air flow and form greater wind resistance, which will directly increase the driving resistance of the vehicle, affecting safety, and also It will make Changan Electric Cars consume more power.
