LITHIUM ION BATTERY FREQUENTLY ASK QUESTIONES

- Sep 16, 2018-

LITHIUM ION BATTERY HAS MANY DIFFERENCE WITH NI-CD/NI-MH BATTERIES DURING CHARGING AND DISCHARGING PROCESS, SO LET'S HAVE A LOOK AT SOME FREQUENTLY ASK QUESTION ABOUT NOMINATIOIN AS LIST BELOW:


FAQ:

What is pulse charging? What is the effect on battery performance?

Pulse charging generally adopts the method of charging and discharging, that is, charging for 5 seconds and then discharging for 1 second. In this way, most oxygen generated during charging process will be reduced to electrolyte under the discharge pulse. It not only limits the gasification amount of internal electrolyte, but also gradually recovers or approaches the original capacity of old batteries that have been seriously polarized after 5-10 cycles of charging and discharging by this charging method.


What is trickle charging?

Trickle charging is used to compensate for the loss of capacity caused by the self-discharging of the battery when it is fully charged. Pulse current charging is generally used to achieve the above purpose.


What is charging efficiency?

Charging efficiency is a measure of the degree of chemical energy that the battery consumes in the process of charging and the amount of energy saved by the battery. It is mainly affected by the battery technology and the working environment temperature of the battery. Generally, the higher the ambient temperature, the lower the charging efficiency.



What is discharge efficiency?

Discharge efficiency refers to the ratio of the actual electric quantity to the rated capacity of the voltage from the discharge to the terminal point under certain discharge conditions, which is mainly affected by factors such as discharge ratio, ambient temperature and internal resistance. In general, the higher discharge ratio is, the lower the discharge efficiency is. The lower the temperature, the lower the discharge efficiency.


What is the output power of the battery?

The output power of a battery is the ability to output energy per unit of time. It is calculated according to discharge current I and discharge voltage, P=U*I, unit is watt.


The lower the internal resistance of the battery, the higher the output power. The internal resistance of the battery should be less than the internal resistance of the electric appliance. Otherwise, the power consumed by the battery itself should be greater than the power consumed by the electric appliance.
