How to properly maintain the lithium battery in the later stage to ensure the service life of the lithium battery of the electric vehicle?

Electric vehicles are currently a common means of transportation that people use when traveling. As the country's environmental protection standards are getting higher and higher, the new national standard electric vehicles are equipped with lithium batteries as the power source. Compared with other batteries, lithium batteries have unique advantage. Lithium batteries have the characteristics of light weight, strong power consumption, and long cycle life. But at the same time, compared with other batteries, the use of lithium batteries and later maintenance are very different. At this time, if we use lithium batteries incorrectly or do not pay attention to later maintenance, it is likely to shorten the service life of lithium batteries. How to properly maintain the lithium battery in the later stage to ensure the service life of the lithium battery of electric vehicles? Several misunderstandings about the battery in the process of using electric vehicles. Misunderstanding 1: Use up the battery before recharging. In the process of using electric vehicles, occasionally The remaining power of the electric vehicle is not estimated, and the excessive driving makes it impossible to drive at all. At this time, whether it is a lead-acid battery or a lithium battery, the damage is very serious. In this case, the lead-acid battery may suffer more damage. Over lithium batteries, because lithium batteries have a protection circuit to protect the battery from over-discharge, but lead-acid batteries do not have a protection circuit, so even in an empty state, lead-acid batteries can still provide weak power, so Give us an illusion that we can continue to use it, which leads to aggravation of over-discharge. The lithium battery has a protection circuit. When the protection circuit is triggered, the battery will directly cut off the output of the power supply. However, frequent deep discharge will aggravate the phenomenon of battery imbalance and directly affect the service life of the battery. This habit should be avoided as much as possible. If you don’t have to, you must reserve 10% of the power for the lithium battery and start charging the battery. Misunderstanding 2: Frequently use fast charging. Generally fast charging is done by increasing the charging current. Achieved, but the current technology, whether it is a lead-acid battery or a lithium battery, does not have the ability to charge with high current. Excessive current will cause chemical and unreasonable reactions inside the battery, accelerating the aging of lithium batteries, and lead-acid batteries The phenomenon of bulging may appear directly. Misunderstanding 3: Do not use chargers as required, or hybrid battery chargers, and electric vehicles have compatible battery chargers. You must use a suitable charger to charge the battery. The charger not only needs to be matched with the lithium battery, but the current of the charger also needs to be matched with the nuclear battery. It is best to make the charger dedicated to the car. Proper use of lithium batteries for electric vehicles ●Charge in time In the daily commuting state, charge in time to keep the lithium batteries with saturated power to provide power to the motor, and avoid excessive discharge during use. If there is a long-term plan, such as when it is not used for more than 3 months, the power of the lithium battery can be maintained at 30%-50%, and it is not necessary to store the battery fully. ●The timing of charging Lithium batteries have no memory effect. Under normal circumstances, they can be charged at any time. In normal use, when the battery power is below 30%, the lithium battery should be charged. ●Charging environment, temperature and humidity To ensure safety, lithium batteries for electric vehicles should be charged in a dry, ventilated, and cool environment. Do not charge the battery in the sun or in a humid environment. ●Clean up in time to eliminate hidden dangers. When you don’t use an electric car in your daily life, in addition to cleaning the electric car, you also need to remove the dust and dirt on the electric bottle cap in time, keep it dry and clean, and prevent the battery from self-discharge. And improper contact causes safety hazards. Summary: The above are several issues that need to be paid attention to in the use of lithium batteries for electric vehicles. Only by mastering these skills can the life of lithium batteries for electric vehicles be longer!
