Media: There are many reasons that affect the continuous flight of electric vehicles, which are divided into two categories. The first category is the same as fuel vehicles, such as heavy vehicle, wind resistance, straight tires, etc.; the second category is the biting cold wind of electric vehicles, and the snow in the community has not melted. Special impact reasons, such as power batteries, motors, electric controls, external environmental reasons, etc. As for the battery itself, there are three important reasons why Sugar baby is important: battery capacity, battery data, and battery system energy density.
Recently, the car and founder Li Xiangpao’s electric car’s continuous mileage promotion has been chaotic. “When many car brands promote electric cars, they still use constant speed to promote their own continuous mileage, and Sugar daddy even directly pasted such false continuous mileage numbers on the butt of the car.” Later, many media jointly advocated that in subsequent reports, they no longer used constant speed range provided by manufacturers. A fierce electric car has continued to fly. Sugar baby.
Electric motor vehicle flights are undoubtedly the most concerned issue for consumers, but the actual range of continuous flights is inconsistent with the manufacturer’s promotion of constant speed flights and NEDC’s comprehensive industrial conditions, and it has also become a year-on-year trouble for consumers. When a certain motor vehicle owner talked about the continuous mileage, he said helplessly, “My car manufacturer claims to be a 360km flight, and he was trapped here after a comprehensive flight. The continuous flight is 305km, and it is actually air conditioning in the summer. It only takes 100km to continue flights.” Consumers couldn’t help but ask, how far can my car Escort manila run?
Consumers’ concern about mileage has always been accompanied by the development of pure electric vehicles, and the power battery has been pushed to the forefront again. However, this “pilot” of the continuous range of electric vehicles is difficult to carry by relying on the battery alone.
Follow the continuous flight of electric vehicles, and the battery is not the “first”
There are good reasons that affect the continuous flight of electric vehicles.There are many types of different types. The first type is the same as fuel vehicles, such as weight, wind resistance, wheel tire straightening, etc.; the second type is the unique influence of electric vehicles, such as battery, motor, electric control, external environmental reasons. As for the battery itself, the reasons that affect the sustained flight are of great importance. Sugar baby must have three points: battery capacity, battery data, and battery system energy density.
On ordinary speaking, the larger the battery capacity, the more energy it can provide, the longer the continuous mileage will be. Sugar babyThis is like the level of the fuel tank of a fuel car that will affect the continuous flight. However, it is worth noting that the better the capacity of the battery pack is, the bigger the capacity of the battery pack, the more core the required number of cores, which means the heavier the quality of the whole car. The overweight girl puts the cat on the service table and wipes it on the side and asks: “With a beltManila escort will have an obscure impact on the continued aviation.
Because of this, light Sugar Baby has always been one of the main goals of electric vehicles. In addition to light quantization of the body and other components, battery packs also require a lighter portion. Therefore, selecting ternary data with higher energy density has gradually become the mainstream.
The batteries commonly used in passenger cars today include phosphate steel batteries and ternary steel batteries, and the two batteries have their own advantages and disadvantages. In actual applications, Sugar Sugar In baby, the phosphate steel battery is high temperature resistant, safe and stable, has a low price, and has good circulation function. The ternary steel battery has a high energy density. Under the similar battery capacity/particle size, the overall preparation of the car with the ternary steel battery is lighter and the continuous mileage is longer..
However, using a three-way battery with a high single energy density, it is unexpectedly possible to obtain a higher range, which also touches the system energy density of the battery pack. As long as the battery pack structure is fairly arranged and each core emits the appropriate energy, the range will be more guaranteed.
In addition to the battery, the protagonist: Song WeiSugar baby, Chen Jubai┃Supporting role: Xue Hua┃Others: These reasons will also directly affect the continuous flight of electric vehicles
A pure electric vehicle driving on the road, requiring a three-system joint mission of motor, battery and electric control.
Electrical motorSugar baby is more than Escort manila, like the “heart” of an electric car, is a driving unit, as a driving unit, Sugar daddyThe whole car function has a strong correlation with the motor, including speeding up time, picking up the location and status at the highest speed, etc. All parameters are determined by the motor. As the overall control of the entire platform, the electric control system determines the speed adjustment, torque control of the motor, and at the same time, it will also control the battery discharge rate and the effect of the high and low pressure of the whole vehicle. It not only controls energy consumption but also takes into account functions, but also meets high dynamics. While escort‘s car frequency is responsive, it also needs to protect the safety of the battery and the motor.
It can be seen from this that the battery, motor and electric control are integrated, and one of them can be missed when they are close together. Can the motor and electric control have the best performance, and will directly affect the sustained range of pure electric vehicles. Therefore, the continuous flight problems of electric vehicles cannot be simple due to the power battery, so we should also pay attention to the main performance of the electric control and motors in this.Foot color.
In addition, some internal reasons such as wind resistance, vehicle weight, speed, driving conditions, weather conditions, driving methods, etc. will also affect the continuous flight of electric vehicles. Therefore, the continuous mileage is affected by multiple reasons and a comprehensive evaluation is still required.
Reduce mileage and new technologies continue to promote industrial development
In recent years, power battery technology has developed rapidly, with the average energy density of passenger car battery systems in 2015 at 97 watts/kg, and from Escort2017 to 111 watts/kg. According to the China Network Statistics, the energy density of pure electric passenger car systems in the first batch of notices in 2018 was 59% of the car models below 140 watts per kilogram. When the proportion of the last batch of notices at the end of the year had dropped to, they rushed into her social media and asked her ideal companion. No 20%. The energy density of the system has also continuously promoted the way of dealing with new power vehicles, but has never been discussed. The growth has had a very positive impact on the development of the electric vehicle industry.
In addition to the energy density fluctuation, the development of various battery products such as hydrogen fuel batteries and solid batteries has also injected new vitality into the electric vehicle industry. The application of multi-special battery products and the reform of battery technology are constantly promoting the development of electric vehicle industry. Trust will come soon, and the issue of sustained range of electric vehicles will gradually fade away, just like we won’t care too much about the continuous range of fuel vehicles tomorrow.
