The 18650 battery charging time is the same, that is, the battery charging time is equal to the ratio of the nominal capacity and the charging current, but the internal impedance is generated during the charging of the lithium battery, so 18650 battery charging Time should be considered to overcome the factors of this impedance. According to the size of the impedance, a coefficient is designed as a comparison value of charging time charging time. After long-term experiments, this coefficient acquisition method is simply a specific gravity of charging current accounting for a nominal capacity.

Thus, the above 18650 battery charging time evolves to: 18650 battery charging time = Nominal capacity ¡Â The charging current ¡Á coefficient is charged according to national standards, charging battery is not higher than 0.2c (C is a nominal capacity), according to this standard The above coefficient is set to at least 1.2, due to the high capacity of the 18650 lithium battery, plus the characteristics of different lithium battery charger manufacturers, generally set the coefficients in the calculation of 18650 battery charging time to 1.

5, charger basically It is designed according to this principle. For example, the 18650 battery is generally 1800 ~ 2600mAh, according to the above formula, the charger selection and 18650 battery charging time (discharge within 0.2c) is generally as follows: 1800mAh generally uses 350mA charger, approximately 7.
