Do you know how to maintain the lithium-ion battery pack?

1. Lithium-ion battery packs have no memory effect. The best way to use lithium-ion battery packs is to charge as you use them without waiting for full discharge. The charging frequency is not a problem. The depth of the charge-discharge cycle affects the lifespan. The best way to use lithium-ion battery packs is The best maintenance method is light use, shallow charge and shallow discharge. The lower the degree of deep discharge of the lithium-ion battery pack, the longer the use time. If possible, try to prevent frequent full charge and discharge. As far as the user is concerned, your battery is best when it is charged at 10% or 20%. 2. The temperature of the operating environment also has an impact on the battery life. If used for a long time below the freezing point, it may have a great impact and harm on the life of the lithium-ion battery pack. Long-term exposure to an overheated environment will greatly reduce the life of the battery. In severe cases, the internal pressure will increase and cause an explosion. Even if there is no explosion, the battery will quickly be scrapped in high heat. In some cases, unfortunately, the battery exploded and died. , Most of the reasons are due to the high temperature of the working environment. 3. The full battery storage has little effect on itself. It is recommended not to emptied storage. Lithium-ion battery packs will self-discharge. The emptied battery will cause over-discharge if stored for a long time. Please keep it in a cool place during long-term storage In a dry place, it is best to store the battery pack separately and do not plug it into tools or chargers. 4. Master the correct charging method. Connect the charger and the lithium-ion battery pack first, and then connect the charger power plug to the 220V AC power supply. Follow this connection sequence to prevent electric sparks when plugging and unplugging the charging plug. When the power is turned on, the charger displays a red indicator light. 5. Prevent the lithium-ion battery pack from being close to heat sources, open flames, flammable and explosive gases, and liquids, which may cause battery leakage, heat generation, and smoke. 6. During use, if the continued mileage of the electric vehicle suddenly drops more than ten kilometers in a short period of time, it is very likely that there is a problem with a battery in the lithium-ion battery pack. At this time, you should go to the sales center or agent maintenance department for inspection, repair or assembly in time. This can relatively extend the life of the lithium-ion battery pack. 1. Prevent the full discharge of the battery (when used until the black screen is turned off) 2. Frequently charge and discharge the lithium-ion battery, charge when the battery is not exhausted, or use an external power supply, use while charging, or continue to use the external connection after the charge is completed , Will not cause additional loss to the battery. 3. When not in use for a long time, the lithium ion battery should be taken out and placed in a cool and dry place. Do not freeze to prevent water erosion. Prevent it from being used in a high-temperature car. If stored for a long time, charge the battery to 40% before storing. 4. As a notebook user, if you use a fixed power supply most of the time, you can remove the battery and place it in a cool place. 5. Recognize the memory effect The memory effect of a battery refers to the reversible failure of the battery, that is, the ability to recover after the battery fails. The memory effect means that the battery automatically maintains this specific tendency after being subjected to a specific working cycle for a long time. Recommendation 1: It is not necessary to discharge the battery before each charge, and it is harmful, because the service life of the battery is needlessly shortened. Recommendation 2: It is not advisable to use a resistor to connect the positive and negative poles of the battery to discharge. The current cannot be controlled, and it is easy to over-discharge to 0V, and even lead to the polarity reversal of the battery in the series battery pack. 6. The battery needs to activate the battery from the battery factory to the user. This time can sometimes be very long, as short as 1 month, and as long as half a year. At this time, because the battery electrode material will be passivated, the manufacturer recommends the battery for the first use. It is best to perform a full charge and discharge process for 3 to 5 times in order to eliminate the passivation of the electrode material and achieve the maximum capacity.
