How long is the life of the battery pack? Discuss the life of the battery pack, first look at what is the battery. At present, mainstream domestic pure electric vehicles, generally used, ferrithium, three-dimensional lithium and lithium titanate three batteries. Among the three batteries, the lithium titanate has the longest life, up to 8 years or more; iron lithium times, generally 5 years; three yuan lithium is the lowest, generally only three years.

However, household electric vehicles (especially cheaper) are generally used in three-dimensional lithium-ion batteries, because its energy density is high, long-range, more in line with the following subsidies, so many manufacturers have adopted This battery. However, when you purchase, what you have to consider is, it is more convenient, but the corresponding durability is worse. And the battery of the electric car is different from the engine, which is not all used as a gear mechanical, but battery chemicals.

So maintenance is quite inconvenient, and now there is still no engine maintenance technology. Therefore, in general, the maintenance is very high, and the recurrence rate is extremely high. Generally does not recommend repair.

If you want to change, then cost is also very high. A set of three-yuan lithium-ion battery, minimized for a set of 150,000, and decided according to models and battery quality). And a set of iron lithium-ion batteries, at least more than 60,000.

Replacement costs are also intended to be included in the car. Is there a way to extend the battery life? Of course, there is, the electric car battery is like a fuel vehicle engine. As long as it protects well, it can also extend its service life: 1.

Regular inspection: whether it is fuel or new energy car, the regular inspection of the car is Indispensable link. It can help find some hidden dangers during use in use, and correctly correct. In addition, if during use, the mileage of the vehicle suddenly decreases, it is likely that there is a problem with at least one battery in the battery pack, and should be sent to the repair shop in time.

2, charging time should not be too long: new energy cars should avoid overcharge, excessive discharge and insufficient charging, these will shorten battery life. The correct use method should determine the charging time and frequency according to the actual vehicle situation. If the power meter indicator is on, it should be charged as soon as possible, otherwise it will cause overemployment of the battery.

And the charging time should not be too long, otherwise it will form excessive charging to heat the battery. If the charging process battery temperature exceeds 65 ¡ã C, the charging should be stopped immediately to avoid danger. 3, gentle start: New energy car is in starting, if the acceleration is stepped on, causing a large current discharge, high current discharge can easily detect lead crystals, thereby damaging the physical properties of the battery pole, affecting the service life.

So, even if the acceleration of electric cars is very happy, don't often step on the electric door. 4, long parking is also charged: Many owners sometimes don't have a car for a long time, it will be too lazy to charge, wait for the next time to use it. In fact, this is extremely bad! Because the battery is stored in the absence of electricity, it is prone to sulfate, and the lead crystals of sulfate is attached to the plate, which is extremely harmful.

So, even if you park your car for a long time, you should also put the electricity. 5, prevent exposure and overclocking: this is also a major drawback of new energy cars: can't survive in an overheating or overwhelming environment. New overheating will increase the internal pressure of the battery to lose water, causing battery activity, accelerate the aging aging;.

Many north owners have said that their electric cars do not dare to open air conditioners in winter, that is, worry about endurance.
