Battery is an important accessory for electric vehicles and one of the three electric systems of electric vehicles. As batteries are expensive, accounting for about 30% of the price of electric vehicles, many people are very concerned about the service life of batteries.lithium ion battery VS lead acid battery Owners who use electric vehicles for a long time will obviously feel that lead-acid batteries are becoming less and less durable. Why is this so? How to improve the service life of electric vehicles? Today I will tell you three practical methods.
Why is the lead-acid battery less and less durable?
Owners who often use electric vehicles feel that the current lead-acid batteries are less and less durable. In the past, the batteries could be used for five to six years, and in the past years, the batteries could be used for three to four years, but from 2019, the batteries can only be used for about two years and need to be replaced. Why is this happening? There are three main reasons.
1, lead-acid batteries to cadmium
Previously, the development of the battery produced by the enterprise in order to be able to increase the life of students using the network, cadmium was added to the battery.lithium battery vs lead acid Although we so that one can carry out the protection of lead plates, enhance its corrosion resistance, increase as well as the use of the battery system life, but cadmium element to the environmental problems caused serious pollution. Therefore, from December 31, 2013, it is prohibited to add cadmium in batteries. This makes the Chinese battery from the original 5 ~ 6 years of service life shortened to 3 ~ 4 years.
2, lead-acid battery weight reduction
In 2019, a new national standard for electric vehicles was introduced, requiring vehicles to weigh no more than 55 kilograms. In order not to make electric cars exceed the standard, electric car manufacturers have asked to reduce the weight of the battery. A battery that originally weighed about 7 kilograms is now reduced to 5.5 kilograms or even only 5 kilograms. This reduces the lead content in the battery and seriously shortens the service life of the battery, which is currently only about two years.
3, electric cars consume more electricity
In addition to batteries, electric vehicles now consume more power. First of all, the battery motor power is larger, faster, ride power consumption will increase. At the same time, electric cars have also added many intelligent features, and even the headlights have begun to shift to the level of the car, making the power consumption of the car greatly increased.
The increase in power consumption of electric vehicles will lead to shorter charging time and more frequent charging, thus affecting the service life of electric vehicle batteries.
It is very practical to tell you three ways to extend the life of your battery.
As a result of analyzing the three main reasons through the above, the use of the battery network life can be significantly shortened. So how do we proceed to extend the service life of electric vehicle battery? Today will tell you three practical ways to make your battery use two more years.
1, choose high-quality batteries
Although all lead-acid batteries, but currently divided into high, medium and low three. When replacing electric car batteries, try not to choose low-grade batteries, because low-grade batteries have lower purity of lead plates, and even use recycled lead, so that the battery life is shorter.
If you are on a budget, try to go for mid-range or even high-end batteries, such as graphene batteries. This kind of battery is slightly more expensive when purchased, but the service life is significantly increased, the output power is more adequate, and the power performance is stronger.
2, the correct charging method
As the saying goes, "bad battery charging, bad use", the correct charging method can effectively extend the service life of the battery. Electric car charging, should pay attention to choose a dry, ventilated, suitable temperature environment.
Pay attention to the length of charging, electric car charger adjust the green light after the general float charging 30 minutes or so, timely unplugging.
Just use the electric car don't because immediately for charging, the same just after charging don't own immediately can use the electric car. To wait more than 30 minutes, so that the battery operating temperature continues to decline before charging or riding an electric car.
Try not to use fast chargers on the street, and not to use high-voltage chargers to charge the electric car.
As long as you choose the right charging method, you can effectively extend the service life of the battery of the electric car.
3, to have good riding habits
Riding an electric bicycle also requires good riding habits, which can also extend battery life. For example, when riding an electric car do not accelerate, do not always turn the switch to the maximum. If the battery continues to discharge high current will affect the range and also affect the battery life.
Also, don't overload it. If it is overloaded, because it needs to discharge a large current to start, it will also affect battery life. When riding an electric bike, try to keep a constant speed, which not only increases the range, but also extends the battery life.
Summarize:
The reason why the current lead-acid battery companies are not durable, not because manufacturers cut corners, but students due to China's battery technology after the "cadmium weight" of the
