The core of gasoline vehicles is the engine, and the core of new energy vehicles is the battery, which represents the first power of the vehicle, and the electric drive the car to run forward. In the new energy era, pure electric vehicles have become the top priority of development, and the first department has been continuously stimulated from all aspects, so there is the current penetration rate.
However, there are still many people who are skeptical of electric vehicles, after all, there are still fundamental problems with electric cars. For example, the battery safety is poor, the battery life is weak, and the battery life is short. For consumers, they prefer to choose a car that is worry-free. Some netizens feedback: If the battery life can reach more than 8 years, new energy can be accepted.
Lithium battery theoretical life
The battery in the vehicle, due to the frequency of use, will lead to the length of the service cycle, but the theoretical number of cycles of the battery is certain. In the lithium battery that exists on the market, in the process of charging and discharging, the electrolyte changes, and it becomes inactive and deteriorated, so the activity of lithium ions inside the battery is poor, which is the reason for the reduction of battery life.
There are corresponding regulations for battery cycles, such as full charge and complete discharge once, which belongs to a cycle, and the current lithium battery cycle life is between 800 and 1500 times, but some people still feel that this cycle cycle is not long enough.
"Inpai Battery" was born
As a core component in a car, it must last long enough. The battery problem has also become the direction of continuous research by various manufacturers, so in the field of batteries, BYD began to study very early, and only then did it have today's blade batteries. Recently, GAC's R&D department has made a big breakthrough in batteries, which has increased the life cycle of batteries.
It is officially announced that the most advanced battery can get 4,000 cycles, and the cumulative mileage life can reach 1.5 million kilometers. And GAC also gave it a nice name called "Inpai Battery", which theoretically increases the number of battery cycles, which means that the service life of the tram is extended. I don't know if this theoretical value can be reached, but at least it has increased compared to before.
The battery will still decay
Made in China has begun to get on the right track, breakthroughs have begun to be made in various technical aspects, and batteries have become the goal of car companies. GAC battery will be released on the 12th of this month, and many car enthusiasts are very concerned about the power battery.
At present, the best battery cycle on the market is 3,000 times, which can achieve a life of 1.2 million kilometers, which is also a theoretical value.
However, the battery will still be accompanied by attenuation, as long as the service life is long, the attenuation exceeds 20%, and the endurance will be significantly reduced. Therefore, some car owners will still focus on long battery life when choosing new energy vehicles.
Not equal to actual lifespan
GAC's new battery has a strong enough cycle capacity of charging and discharging, and at the same time, the mileage has reached 1.5 million kilometers, and theoretically speaking, the life of an electric car is even longer than that of a gasoline car.
But please remember that this refers to the theoretical lifespan, theoretically there is no problem with the tram driving for 10 years, in fact, the battery will decay, and even CATL and BYD can't equate the actual and theoretical. At present, although pure electric vehicles have achieved lower economy in terms of travel, battery maintenance and replacement in the later stage are a large expense.
At present, the theoretical data given by the manufacturer can only be used as a reference, not seriously.
Increased battery density
Many people are curious about the material of "Inpai battery", it is understood that it uses lithium iron phosphate, and from the characteristics of the material, the number of charge and discharge is greater than that of ternary lithium.
However, the density of the battery is relatively low, in order to have a better life, larger manufacturers are working the battery density, GAC has increased the density of the Inpai battery to 1465kWh kg, which can meet the needs of low-end cars.
In addition, the safety of this power battery is strong enough, and it has reached the level of military level, and it is said that even if it encounters **, the battery pack will not **. Whether it is really that safe is unknown.
In the future, power batteries will be more diversified, the types of cars will increase, and the types of batteries will also increase. But the life and life cycle of the battery, no one dares to pack a ticket, because it takes time to verify, but as long as the car dealers have progress, this is a big step in development, I believe that one day, there will be a solution for the life of the power battery!
