Lithium battery discharge what little knowledge need to master?

Source: 2020 - 03 - 28 14:14 hits: lithium-ion battery discharge need to grasp what little knowledge? 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 the voltage to 3 v, the charging process into the specification. The charging process is as follows: constant current charging current through setting, when the lithium battery voltage up to 4. 20 v, to constant voltage charging, charging voltage adhere to 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. The electrochemical response of batteries at this time due to the internal demand, charging current is too large, lack of capacity. Like a beer, too fast will cause bubbles and dissatisfaction. 1. Discharge current shoulds not be too large, otherwise it will cause fever, lithium-ion batteries cause permanent damage. 2, can't discharge, the most afraid of lithium-ion batteries discharge, once the discharge voltage is lower than 2. 7 v, can lead to dead batteries; 3, ban depth charge and discharge frequently: lithium battery almost no memory, a lot of people in the use of digital products lithium trams perhaps lithium electricity, like to use the rest of the electricity ( Maintenance maintenance) And then, in the eyes of many people, this is also a method to activate the battery; 4. On a charge and discharge, the charger of electric current and electric current load shall be within the prescribed scope: easy to cause the battery short circuit current load is too high, which damage the lithium ion, the safety of circuit; 5. Lithium battery is sensitive to temperature. If long time used in below freezing point, it may have a big impact and harm to the battery life-span. Overheating and for a long time in the environment, will greatly reduce the service life of the battery, serious is caused by internal pressure explosion, even if they failed to explode, waste batteries will be flexible in the heat.
