QUENENG editor will take you to know what the battery capacity is?
The rated capacity of the battery refers to the design and manufacture of batteries, or to ensure that the battery, under certain discharge conditions, should discharge the minimum amount of power.
There are rated capacity and actual capacity of batteries.
The rated capacity of the battery refers to the design and manufacture of batteries, or to ensure that the battery in certain discharge conditions, the minimum amount of power should be discharged. IEC standards provide for nickel-cadmium and nickel-metal hydride batteries in the environment of 20 ℃ ± 5 ℃, to 0.1C charge for 16 hours and then discharged to 0.2C 1.0V when the amount of power discharged as the battery's rated capacity, expressed in C5.
For lithium-ion batteries, it is stipulated that the rated capacity is the amount of electricity discharged when the battery is charged for 3 hours at room temperature under the charging conditions of constant current (1C)-constant voltage (4.2V) control and discharged to 2.75V at 0.2C, while the actual capacity of the battery refers to the amount of electricity discharged by the battery under certain discharging conditions, which is mainly affected by the discharge multiplication rate and the temperature (therefore, the capacity should be specified as the rated capacity). Strictly speaking, the battery capacity should specify the charging and discharging conditions.
The unit of battery capacity is Ah, mAh (1 Ah = 1000 mAh).

Battery and Analysis
What are the control methods to prevent battery overcharging?
1) Peak voltage control: Determine the end of charging by detecting the peak voltage of the battery;
2) dT/dt control: determine the end point of charging by detecting the battery peak temperature change rate;
3) △T control: When the battery is fully charged, the difference between the temperature and the ambient temperature will reach the maximum;
4) -△V control: When the battery is fully charged and reaches a peak voltage, the voltage will drop by a certain value;
5) Timing control: Control the charging end point by setting a certain charging time. Generally, set the time required to charge 130% of the nominal capacity;
