How long is the lithium-ion battery charge? How to calculate lithium battery charging time? Lithium-ion battery charging time, from difficult to the extent, the operation problem is not large, understand the origin of the charging time of lithium ion battery more helpful in theory and practice. In general, the charging time of the lithium-ion battery is related to the battery capacity and charging current, in general, the maximum charge current of the ordinary lithium ion battery is 1C. How long is the lithium-ion battery charge? The first charging time of the specific lithium ion battery can be determined according to the actual battery capacity.

The first charge of the lithium-ion battery is full, not necessarily 12 hours, the current lithium-ion battery and the battery of the old mobile phone are different, about 2 ~ 4 hours can be full. The lithium-ion battery is a complete charge. The first charging time can be grasped in 5-6 hours, allowing the battery to make the battery.

Nowadays, the charging speed of the lithium-ion battery is now not fixed. According to the capacity of the battery itself, the current size of the charger and the like of the conversion efficiency of the charged conversion efficiency are determined; if your battery capacity is large, you The charger is smaller, no maximum input current, the speed of charging will slow down. The battery capacity is MAH (mA, how many martial discharge speeds are discharged, which can be discharged for one hour.

1500mAH battery is discharged at 1500 mAh can be used for an hour, with 500 mA (500mA) discharge speed, 3 hours. Generally, the charging current of the lithium-ion battery is set between 0.2c to 1c, the larger the current, the faster the charging, the greater the battery heat generation.

Moreover, excessive current charging, the capacity is not full, because the electrochemical reaction of the battery is time. It should be noted in the use of a lithium ion battery that the battery is placed in a sleep state, at which time the capacity is below normal, and the usage time is also shortened. However, the lithium-ion battery is easily activated, and the battery can be activated as long as it passes through 3-5 normal charge and discharge cycles, and normal capacity is restored.

How to calculate lithium battery charging time? Theoretically lithium battery charging time is the ratio of battery nominal capacity and current: lithium ion battery charging time (h) = battery capacity (MAH) ÷ charging current (MA). Lithium-ion battery charging time = battery capacity ÷ charging current × 1.6, in this type, according to the size of the battery capacity share according to the charging current, the coefficient of charging the charging time is 1.

5 hours; but in practice, the charging time is longer than the theoretical time, because the energy is expensive during charging. Enhancement of charging voltage can progress to charging power. Summary: The relationship between the charging time and charging current of the lithium-ion battery is the battery capacity divided by the charging current, considering the loss during the charging process, so the calculated charging time is multiplied by 1.

1 or 1.2.
