Lithium-ion battery manufacturer interpret 18650 lithium ion battery charging method. 18650 lithium-ion battery charging method is more strange to many friends, or many people do not understand the correct lithium-ion battery charging method. It is whose approach is, there may be different lithium ion battery charging methods for different types of lithium-ion batteries.
In this paper, the lithium-ion battery manufacturer will introduce 18650 lithium-ion battery charging method. Lithium-ion battery manufacturer Interpret 18650 Lithium Ion Battery Charge Method 18650 A number of numbers in the lithium ion battery, representing the outer surface size: 18 refers to the battery diameter of 18.0mm, 650 refers to the battery height 65.
0mm. Common 18650 batteries are divided into lithium ion batteries, lithium iron phosphate and nickel-hydrogen batteries. The voltage and capacity specification is a nickel-hydrogen battery voltage of 1.
2V. The common capacity is 2500mAh. The lithium ion battery voltage is 3.
6V is a common capacity of 1500mAh-3100mAh. 18650 lithium-ion battery charging can be broken down into 18650 battery charging method, 18650 lithium-ion battery charging conditions and 18650 lithium ion battery charging precautions, etc. 18650 lithium-ion battery charging time = battery capacity ¡Â Charging current ¡Á 1.
5 (coefficient) General 18650 lithium ion battery charge 10 hours substantially full power, due to the charger of lithium-ion battery manufacturers generally have constant voltage after constant current charging So don't have to consider over 10 hours. 1. Standard charging current 0.
2c, that is, one-fifth of the nominal capacity, according to the capacity of the 18650 lithium-ion battery on the market, generally 350mAh or 400mAh, and the limit temperature at the time of charging, try to prevent it Charging below 0 ¡ã C, otherwise, the lithium-ion battery life will be severe; The normal state, the method of preventing overcharge; 4, when the electricity is too low, the 18650 lithium ion battery can be charged without having to wait until the battery is placed in the termination voltage, so as not to occur. In theory, 18650 lithium-ion batteries can recharge one thousand times, this is its life, so we use the laptop battery usually choose 18650 lithium-ion battery as a battery. 18650 lithium ion battery charging control is divided into two phases, the first stage is constant current charging, when the battery voltage is below 4.
2V, charger will charge a constant current. The second stage is a constant voltage charging phase. When the battery voltage reaches 4.
2V, due to the lithium ion battery characteristics, if the voltage is high, it will be damaged, the charger will be fixed at 4.2V, and the charging current will gradually decrease. When the current decreases to a certain value (usually 1/10 set current), cut off the charging circuit, the charge is completed, and the charging is completed.
With regard to the charger of the 18650 lithium-ion battery, it is necessary to control the accuracy, because if the accuracy is not good enough, the battery will easily appear abnormalities, the worst, the battery scrap. Summary: The content introduced above includes the 18650 lithium-ion battery charging method, because the standards required in this area are high, so everyone is best suggested, prevent unnecessary losse.
