Why is there a difference in cruising range between new energy vehicles with the same battery capaci

As new energy vehicles become more and more popular, many automobile enthusiasts have a certain understanding of them. Of course, some friends will face such questions when purchasing new energy vehicles: why are there differences in cruising ranges even if they are two models with the same capacity battery? For example, the ES8 just launched by NIO is equipped with the same 100 kWh ternary lithium battery as the Tesla Model X, but its cruising range is 5 kilometers longer than that of Tesla. So, besides battery capacity, what other factors will affect a car's range?

The first thing to mention is the energy density of the battery. Battery energy density is the energy contained in a unit volume. Although the batteries of the Tesla model?, the cruising range also varies accordinglyin this. Therefore, when we choose new energy vehicles, energy density can be used as an important criterion to measure battery performance.

Second, in addition to energy density, the operating efficiency of the generator will also affect the cruising range. Currently, there are two main types of common motors: permanent magnet synchronous motors and asynchronous motors. The main difference between these two types of motors lies in the structure of their rotors. Generally, permanent magnet synchronous motors have a magnetic core in the middle when powered, the magnetic core can generate a certain magnetic field to promote the movement of the rotor. . This can actually increase energy consumption. An asynchronous motor does not have a magnetic field when it is turned on, so it consumes a lot of energy and the range of the car is reduced.r affected to some extent. Tesla, on the other hand, likes AC asynchronous motors, which can guarantee higher speeds and higher torque and improve power performance.

Finally, in addition to the above two factors, the contents and materials of batteries will also affect energy storage. Most electric vehicles in the automobile industry currently use lithium batteries, but there are differences in their content, such as lithium. iron phosphate batteries, lithium cobalt oxide batteries, ternary lithium batteries, etc. are all lithium batteries.

To summarize, when the battery capacity is the same, many factors still affect the cruising range. In addition to energy density, the content and materials of the motor and battery will also affect cruising. range. For those who wish to purchase aelectric car, they still need to find out more and make a reasonable choice based on their real needs.

Which brands are best in producing lithium micro-battery automobile technologies?

What are the classifications of electric vehicle batteries?

They are divided into two categories: batteries and fuel cells.

Battery cells are suitable for pure electric vehicles, including lead-acid batteries, nickel-copper batteries, nickel-metal hydride batteries, sodium-sulfur batteries, carp secondary batteries, air batteries.Batteries, electricitypure traditional mainly uses carp batteries

The most commonly used on the market are:

Potassium iron phosphate batteries: such as Hongguang MINIEV, BYD, Xiaopeng Sanyuan ; Carp Battery: Nezha, Wei Lai, Tesla;

A fuel cell is a chemical device that directly converts the chemical energy of fuel into electrical energy. It is also called an electrochemical generator and is mainly used for hydroelectricity. thermal power, atomic power.

What are the advantages and disadvantages of lithium batteries?

Advantages of ferrophosphate batteries

1. Good safety performance, P-0 bond in ferrophosphate crystal. is stable and difficult to decompose, even at high temperatures or overload, the structure will not collapse and generate heat or form strong oxidizing substances like acid, itIt therefore presents good security. 2. Long life, the life of the phosphor battery can reach more than 2000 times, and the theoretical life can reach 7-8 years

3. It has good resistance to high temperatures and a peak. temperature resistance can reach 350"C-500"C. 4. Large capacity, can be charged and used regardless of the state it is in. 5. Environmentally friendly, ferrophosphate batteries are considered to contain no heavy metals or rare metals, are non-toxic, non-polluting, comply with European ROHIS regulations and are absolutely environmentally friendly battery certificates of the environment.

Disadvantages:

Poor performance at low temperatures; low grip density of positive material; poor conductivity, slow diffusion of ions and low actual specific capacity when charged and discharged at timess high.

Advantages and disadvantages of ternary lithium batteries

Advantages:

1. The charging speed is fast, and the battery voltage reaches 3.7V, which can supply enough. electric support for the car.

2. Low temperature resistance, even at temperatures as low as minus 20 degrees, it can ensure good operating performance of the battery

3. The battery has high energy density and small overall size. volume and weight.

Disadvantages:

1. Battery life is relatively short, may not reach 2000 times

2. The heat resistance is low and the battery self-ignition is high. .

3. The raw material cost of batteries is high
