28 'hits: lithium-ion battery discharge what need to pay attention to at the beginning of the charging voltage should be tested for rechargeable batteries.
If the voltage is lower than 3 v, should be in charge.
1/10 of the charging current to set current, generally in 0.
About 5 c.
After rising voltage to 3 v, in the process of charging standard.
Standard charging process is: to set for constant current charging current, when the battery voltage up to 4.
20 v, a constant voltage charging, charging voltage at 4.
20v。
The charging current gradually decreases, and when current to set up 1/10 of the charging current, charging is over.
Lithium battery charging current general set at zero.
Between 2 c and 1 c.
The faster the current, the greater the charge, the battery heat.
In addition, too much current is not enough to recharge the battery, because inside the battery electrochemistry reaction takes time.
Like a beer, too fast will produce bubbles, lead to dissatisfaction.
Terms: generally called C, charge and discharge current is with battery capacity corresponding values.
Battery capacity generally use Ah, mAh, such as M8 battery capacity is 1200 mAh, the corresponding C is 1200 ma.
0.
2 c is equal to 240 ma.
Lithium battery discharge, for the battery, the normal use lithium battery discharge is discharge process only need to pay attention to the following: 1.
Discharge current shoulds not be too large, otherwise it will cause the battery heat and cause permanent damage.
Never excessive discharge!
Lithium battery is the most afraid of discharge, once the discharge voltage is lower than 2.
7 v, is likely to lead to dead batteries.
As can be seen from the discharge curve, the larger the discharge current, discharge capacity is smaller, the faster the voltage drop.
So, under normal circumstances, the battery work load, load drop will appear the phenomenon of voltage rise, referred to as the 'back' phenomenon.
