You have to know: lithium-ion battery pack use precautions and maintenance methods. Since the lithium-ion battery, since its excellent performance, the unparalleled advantages have been rapidly developed, and is widely used in various scenarios and quickly occupies many fields. But most people use and maintain lithium-ion battery packs are not very clear.

In order to better, use lithium-ion batteries more securely, this paper details the correct protection methods and precautions of lithium-ion battery packs. 1. Lithium-ion battery charging precautions: lithium-ion battery is strictly prohibited from charging from the discharge terminal, and must be charged from the charging socket using a special charger.

When the charging indicator on the charger stops scrolling, remove the charging plug in time to avoid the battery over charge. 2, discharge precautions: lithium-ion battery pack has overcurrent protection function, when the usage current of the electric device exceeds the maximum output current of this product, the overcurrent protection circuit action does not work properly. 3, daily use precautions: The output of the discharge terminal is not controlled by the switch control on the panel, only the battery voltage is lower than 9.

0V, the discharge terminal is turned off. The switch on the panel controls the display and USB socket output. When the switch is turned on and the battery voltage is ≤9.

1V, the display will flash in a second-off frequency flashing, you should charge it in time, when the battery voltage is ≤9.0V The screen is off and the USB socket is turned off, the purpose is to protect the lithium-ion battery is not over-discharge. Although there is an output short circuit protection function, short circuits should not be frequent in daily use +, - power output.

4. Recycling precautions: The normal circulation of the lithium-ion battery is approximately 500-800 times, and the lithium-ion battery to life-end is to recover and process according to local law. 5, lithium-ion battery usage environment and maintenance method: ☀ temperature should be suitable, lithium ion battery charge temperature is 0 ° C ~ 45 ° C, lithium ion battery discharge temperature is -20 ° C ~ 60 ° C; ☀ should be cleaned, dry, ventilated In the environment, it should be prevented from contacting with corrosive substances, away from fire sources and heat sources; ☀ Lithium ion battery pack does not have memory effect, but it can be followed, but it is important to note that the lithium ion battery cannot be over-discharge, and excessive discharge can cause very Large capacity loss; ☀ Do not put the battery with the metal object to avoid metal objects to touch the positive and negative poles of the battery, cause short circuit, damage the battery, and prevent frequent excessive charging, excessive charging will increase the temperature inside the battery High, harmful to lithium ion batteries and chargers.

Therefore, as long as it is fully charged, you will make your lithium ion battery become a small bomb. Summary: The battery is a convenient product, its life is certain (the number of charge and discharge is usually 300-500 times), so the correct way to use is the secret of battery "prolonging life". 6, battery maintenance of the correct use of lithium ion battery packs: charging: lithium electric safety operating voltage ranges from 2.

8 to 4.2V, lower than or higher than the lithium ion in the battery in this voltage range is very unstable, and even cause an accident. In order to ensure that the battery is in a safe range, it is a special charger.

Lithium-ion batteries need to be charged and discharge cycles every three months to restore their original performance. Lithium-ion batteries need to be checked whether the load is satisfied, and the battery can be shortened or life without reaching the load requirements or large currents (more than 1C). Prevent often use in high temperature or low temperature environments.

Preferably, at room temperature, the temperature will have a great impact on the characteristics of lithium ion battery. 7, the advantages of lithium iron phosphate ion battery pack: ✔✔ Long life, lithium iron phosphate ion battery, more than 2,000 cycle life, standard charging (5 hours), can reach 2000 times. ✔ High temperature performance, lithium iron phosphate electric heating peak can reach 350 ° C to 500 ° C.

Wide work temperature range (-20c - + 75c), high temperature resistant characteristic phosphate hydraulic peak is 350 ° C to 500 ° C. ✔ Safe and reliable, the P-O bond in the lithium phosphate crystal is stunned, it is difficult to decompose, even if it does not cause heat or forming a strong oxidizing material as the same structure as the lithium cobalt or overcharge, therefore has good safety. ✔ No memory effect, the rechargeable battery is often in the case of not finishing, the battery is in any state, can be accompanied by charging, no need to put it first.

✔ Small size, light weight, large capacity, and equivalent capacity of lithium phosphate ion battery is 2/3 of the lead-acid battery volume, weight is 1/3 of the lead acid battery. ✔ Green environmentally, in line with European RoHS, for absolute green environmental batteries. ✔ 冲 The electricity energy is good, the lithium-ion battery pack charging power conversion efficiency can be greater than 97%, at the same temperature, the discharge current of different magnifications is used, and the discharge output characteristics are very stable.

✔ Quick charging: High current 2C fast charge and discharge, can charge the battery in a special charger to charge 40 minutes, start the current up to 2C. In short, develop a good habit, be kind to your lithium-ion battery, regularly maintain it, properly, so that the life of the lithium ion battery pack will be greatly extended. .
