What is the reason for the reduction in the life of the electric vehicle lithium-ion battery pack? The endless mileage is a very important indicator to determine the performance of electric vehicles. With the new time of electric vehicles, the battery life of the electric vehicle lithium-ion battery pack will be getting lower and lower, bringing great inconvenience to travel. Regardless of the battery, the car will cause the battery to decrease in a period of time, which is the congenital defect in the use of lithium-ion battery packs.
What is the reason for the reduction in the battery pack of the electric vehicle lithium-ion battery group? Improper use. This must be replaced by inferior batteries or form a good riding habit and charging method. Some lithium-ion batteries manufacturers use refurbished batteries or unqualified product batteries.
It is still not used for more time, it is easy to cause safety accidents. Some users have not formed a good charging habit until they are used, and then charge the charger, which seriously shortens the use of the lithium-ion battery pack of electric vehicles. 2.
Causes of chargers The charger has a very important use of electric vehicle lithium-ion battery packs, and unqualified chargers are full of market. Some merchants use unqualified products to customers for their economic interests. The charger is also used in service life, especially under high temperature environments, which is prone to accidents.
Either the charging current is too small, or the charging voltage is not enough, or these two reasons. The lithium-ion battery pack cannot be full, the capacity is not enough to electric car. 3.
The reason for the electric car itself is sometimes rain, wet electric car, or the weather is more humid, resulting in short circuit short circuits. This seriously consumes the capacity of the electric vehicle lithium-ion battery pack. Especially pay attention to the brakes of electric vehicles.
Sometimes the electric car's brakes have not returned, so that more power is consumed when riding. There is also the power drop of electric vehicles' motors. 4.
Resistance problem The capacity of the lithium-ion battery pack does not change, and changes are resistant, compared to the resistance of summer winter, to achieve the same power, only increase the output, so in capacity In the case of constant, the battery looks quickly. 5. Battery energy density and material are currently important to two material batteries of lithium iron phosphate ion batteries and ternary lithium ion battery packs, battery energy density determines battery charge.
The energy density of the three-dimensional lithium-ion battery pack is good, but it is easy to explode under strong collision. As the development, the performance of the three-dimensional lithium-ion battery is rapid, and the life will be expected. It turns out that no matter whether it is charging the electric vehicle lithium-ion battery pack using the original charger or to the smart charging pile in the community, with the new increase of electric vehicles, battery life will decrease, and The most effective new battery life is the electric vehicle lithium-ion battery pack for electric vehicle.
The above is the analysis of the factors affecting the lithium-ion battery pack of electric vehicles. It is very important for electric vehicles. The battery life is an important criterion for evaluating quality of electric vehicles.
In theory, the lithium-ion battery has a battery life than the battery.
