Why is your electric car battery always short-lived?

The same brand of electric vehicle battery, some people have been riding for three or four years, still in use, and some people are scrapped after less than a year of riding. This situation is not uncommon, on the contrary, it is very common. So why does this happen? Why are some people's electric car batteries so short-lived?

1. Working principle
In general, electric vehicle batteries use lead-acid batteries, and the battery charging and discharging process is an electrochemical reaction process. When charging, lead sulfate will form the necessary lead oxide, and when discharging, it will be reduced to its original state. In this way, the charging and discharging process can be completed repeatedly. Lead sulfate is actually a very easy to crystallize substance. If this substance is not used for a long time, it will form small crystals, which will affect the quality of the battery. This is also the reason why some long-standing electric vehicle batteries have reduced capacity.

The process of charging and discharging is to make this transformation complete, so as to avoid the appearance of crystals, or reduce the number of crystals, and naturally the capacity of the electric vehicle battery will be guaranteed. However, many people ignore this point in the process of use, which will eventually lead to damage to the battery and reduce the service life.

2. Improper operation
Don't think that you have no improper operation. In fact, 90% of consumers have wrong operations when using electric vehicle batteries. For example, some people do not like to charge in time, but prefer fast charging. I usually do not charge electric vehicles. When it is almost gone, I will use the charger to charge it for a while, and then I will not charge it when it is enough. This approach will undoubtedly shorten the life of the electric vehicle battery by a large part.

In addition to this, there are also exposure to the sun, charging at high temperatures, and using mismatched chargers, etc., which are very harmful to electric vehicle batteries.

3. Many times of braking
Braking is the most common behavior, but the damage to the battery of an electric vehicle caused by frequent sudden braking is unpredictable for a layman. When many people ride electric vehicles, the speed is very fast. When encountering obstacles, they brake urgently, which increases the burden on the battery and reduces the service life of the electric vehicle battery.

No matter how good the electric vehicle battery is, it can't stand human damage. Although the electric vehicle batteries produced by many manufacturers have a long service life, if you don't know how to maintain them all the time, it is difficult to say the length of the service life.
