Lithium iron phosphate battery. Ternary polymer lithium battery. During the charging process, part of the lithium lithium iron phosphate is detached, transferred to the negative electrode through the electrolyte, and embedded in the negative electrode carbon material. At the same time, electrons are released from the positive electrode, and the external circuit reaches the negative electrode, maintaining the balance of the chemical reaction.

During the discharge process, lithium ions come out from the negative electrode and reach the positive electrode through the electrolyte, while the negative electrode releases electrons and reaches the positive electrode from the external circuit to provide energy to the outside world.

Precautions for new energy vehicles.

Before stopping, ensure that the SOC status of the battery system is 50%, and at the same time, the meter should be turned on every 3 months, and check whether the lowest single string voltage displayed on the instrument is lower than the SOC state after long-term storage, which may be inaccurate, based on the single string voltage), if it is lower than 50% of the SOC state of the battery system, to avoid irreversible losses.

In the normal operation of the car, in order to prevent excessive frost on the evaporator and affect the operation of the air conditioning system, the air supply speed and temperature control of the air conditioner should not be placed in the lowest position for a long time. However, when the speed is less than 25km/h, the wind speed switch should be set to the low speed gear to avoid insufficient power generation and air conditioning.

1. Lithium cobalt oxide battery.

Lithium cobalt oxide battery is a relatively common battery in electronic products, which is often used in laptop batteries and used as battery cells.

Advantages: The production technology is mature, the energy ratio is high, and the energy ratio is about twice that of lithium iron phosphate batteries. Disadvantages: At high temperatures, the stability is slightly worse than that of lithium nickel-cobalt-manganese oxide batteries and lithium iron phosphate batteries. Representative models are: Tesla Model S

2. Lithium iron phosphate battery.

Lithium iron acid battery is a lithium-ion battery that uses lithium iron acid as the cathode material. (The cathode materials of lithium-ion batteries mainly include lithium cobalt oxide, lithium manganese oxide, lithium nickel oxide, ternary materials and lithium iron phosphate, etc.).

Advantage: The stability is the best among the current automotive lithium batteries.

Disadvantages: There is still a big gap in energy density compared with ternary lithium batteries and lithium cobalt oxide batteries. In addition, when the temperature is lower than -5, the charging efficiency decreases.

And when the temperature is too low, it will affect the capacitance of the battery. The models used in lithium iron phosphate batteries are not suitable for driving in the north, especially in extreme cold areas such as the northeast, because the temperature in winter there is too low, which will affect the service life of lithium iron phosphate batteries. The representative models are:

BYD E6, BYD Qin, BYD Tang, etc.

3. NiMH battery.

NiMH batteries, which are synthesized from hydrogen ions and nickel metal.

Advantages: The battery has a large energy reserve, is lighter, has a longer service life, and is non-polluting to the environment. Disadvantages:

The manufacturing cost is too high, and the performance is worse than that of "lithium batteries". Representative models include: Toyota Prius, Ford Escape, Chevrolet Chevroiet Malibu, etc.

Fourth, ternary lithium battery.

Ternary lithium battery refers to a lithium battery whose cathode material is lithium-nickel-cobalt-manganese ternary cathode material.

Advantages: Compared with lithium cobalt oxide batteries, ternary lithium batteries are safer. It is more suitable for the development trend of new energy vehicle batteries in the future, suitable for northern weather, and the battery is more stable at low temperatures.

Disadvantages: The voltage is too low, and the energy density is between lithium iron phosphate batteries and lithium cobalt oxide batteries. The representative models are:

BAIC BJEV EV200, BAIC BJEV EU260, Tesla Model 3, etc.

There are many types of batteries for new energy electric vehicles. There are lead-acid batteries, nickel-metal hydride batteries. Lithium iron phosphate battery. There are also several types of ternary lithium batteries. Some have a low cost, and some have a high charging capacity. The battery is not the same at different price points.

New energy vehicle batteries are mainly divided into the following types: first, lead-acid batteries. Second, nickel-metal hydride batteries. Third, lithium batteries. High-speed vehicles are generally dominated by lithium batteries.

Different brands of car manufacturers choose different battery manufacturers.

At present, lithium batteries for electric vehicles account for a relatively large proportion.

Lithium iron phosphate battery, ternary battery, blade battery.

The types of new energy electric vehicle batteries are roughly classified into lead-acid batteries, nickel-metal hydride batteries, lithium manganese oxide batteries, lithium iron phosphate batteries and ternary lithium batteries.

1. Lead-acid battery.

Lead-acid batteries have low cost, good low temperature performance and high cost performance; Low energy density, short life, large size, poor safety. Due to the low energy density and service life, electric vehicles that are powered by electric vehicles cannot have good speed and high range, and are generally used for low-speed vehicles.

2. NiMH battery.

NiMH batteries have low cost, mature technology, long life and durability; Low energy density, large volume, low voltage, and battery memory effect. Although the performance is better than that of lead-acid batteries, it contains heavy metals and causes pollution to the environment after being discarded.

3. Lithium manganese oxide battery.

Lithium manganese oxide battery has low cost, safety and good low temperature performance of the cathode material, but the material itself is not very stable, easy to decompose and produce gas, so Tong is mostly used for mixing with other materials to reduce the cost of the cell, but its cycle life decay is fast, easy to bulge, poor high temperature performance, relatively short life, mainly used for large and medium-sized batteries, power batteries, its nominal voltage is.

4. Lithium iron phosphate battery.

Lithium-ion iron phosphate batteries have good thermal stability, safety, low cost, long life, low energy density, and low temperature resistance. When the temperature of the battery is 500-600, its internal chemical composition begins to decompose, and puncture, short circuit, high temperature will not burn or **, and the service life is also long. However, the vehicle mileage is average, and when the temperature is lower than -5, the charging efficiency is low, which is not suitable for the needs of charging in the north in winter.

5. Ternary lithium battery.

Ternary lithium-ion batteries can talk about high density, long cycle life, and not afraid of low temperature; Insufficient stability at high temperatures. The energy density can reach the highest, but the high temperature is relatively poor, and the pure electric vehicle with requirements for cruising range is the mainstream direction, and it is suitable for northern weather, and the battery is more stable at low temperature.

The battery life of new energy vehicles is generally about eight years; So you can consider replacing the battery once in about eight years:

1. The battery packs in electric vehicles are currently using the more popular lithium battery packs on the market. The advantages of lithium batteries are more power storage, large discharge, long life, no pollution, etc., but although the life is long, with the passage of time and use, the efficacy will still be weakened;

2. Due to the different quality of the battery and personal driving habits, it cannot be judged according to the standards of the factory, and it is necessary to master a standard for judging the replacement of the battery pack. For example, if you usually charge it for 1 hour and it can be fully charged, but this time it only takes 30 minutes to charge the battery and the battery is full, so you can judge that the capacity of the battery pack has become smaller, and you should check or replace it;

3. Sometimes it is not accurate to judge by charging time, and the most accurate way is to judge by driving mileage. If you can drive 300 kilometers on a full charge, if you can only drive 150 kilometers after being fully charged this time, it is likely that the battery capacity is insufficient and the battery needs to be checked or replaced;

4. At present, the warranty period of lithium battery packs by automobile manufacturers in the market is set at 10 years and 200,000 kilometers. That is to say, as long as there is a problem with the battery pack within 10 years or 200,000 kilometers, the manufacturer can repair it for you in accordance with the warranty provisions;

5. Through this parameter, it can be inferred that the longest life of the lithium battery pack should be greater than or equal to 10 years, of course, for the convenience of using the car, about 10 basically need to be replaced.

Millions of car purchases to supplement macro concessions.

<> "New Energy Vehicle Battery.

What are the classifications of new energy vehicle batteries.

New energy (NE), also known as unconventional energy, usually refers to various forms of energy other than traditional energy, including solar energy, wind energy, marine energy, biomass energy, hydrogen energy and nuclear energy. With the progress of technology and the establishment of the concept of sustainable development, new energy with environmental protection and renewable characteristics is one of the main energy options to meet the needs of green and sustainable development of human society. With the development of new energy technology, new energy battery technology is becoming more and more mature.

At present, the classification of new energy vehicle batteries is mainly classified from two aspects, one is the battery material, and the other is the battery packaging shape. According to the battery material, it can be divided into lead-acid battery, nickel battery and lithium battery. According to the package shape, it can be divided into cylindrical batteries, prismatic batteries and pouch batteries.

Classification by battery material.

Lead-acid battery Lead-acid battery, made of lead and its oxide as the electrode material, sulfuric acid solution as the electrolyte, which is now the power source of the battery car of the big pei roll part, low cost is its biggest advantage. But it has two major drawbacks; First, the specific energy is low, the mass and volume occupied are too large, and the mileage of a single charge is short; The other is that the service life is short and the cost of use is too high. This annihilation.

Classified by battery package shape.

Cylindrical batteryCylindrical batteries are more common in daily life, and Tesla, the benchmark of the electric vehicle industry, is the use of this battery shape, its production process is very mature, and the performance is relatively stable. The reason why Tesla chose this battery shape is mainly because when it is packed, there will be some pores between the battery and the battery, and these pores can provide heat dissipation space for the battery well, effectively avoiding the battery from overheating. However, because this kind of battery uses a metal shell, it is relatively heavy, and the energy density of a single battery is not very high.

Prismatic battery Prismatic battery is also very common, most of the electric spare motorcycles are also used this kind of battery, one of the characteristics of this battery is light weight, high energy density, power supply capacity is very strong. In electric vehicles, in addition to the above advantages, it also has a big advantage that it can be customized according to different cars, and the safety is very good. And the disadvantage of this battery is that the standard is difficult to unify, and the battery model of each car is not the same, which is easy to cause market confusion.

Pouch battery The most common pouch battery is the battery in our mobile phone, because there is only a layer of aluminum-plastic film as the packaging material, so the weight of this battery is the lightest of several batteries, and the energy density is not low, from the mobile phone such a small battery can standby for several days can be seen. However, because of the use of aluminum-plastic film as the encapsulation material, its safety is poor and the protection measures are weak.
