Over charging and charging of lithium batteries.best trolling motor battery

　　Overcomplactify

　　All lithium -ion batteries, including polymer lithium -ion batteries, lithium -iron batteries, etc., are very afraid of over -charging.

　　If the charging time is too long, the possibility of explosion will increase.

　　The chemical properties of the lithium are very lively and easy to burn. When the battery is filled and discharged, the internal heating of the battery continues to heat up. The pressure reaches a certain degree. If there are scars in the shell, it will rupture, causing leakage, fire, and even explosion.

　　Therefore, everyone should pay great attention to safety when using lithium ion batteries.

　　Charge

　　Charging is an important step for battery reuse. The charging process of lithium -ion batteries is divided into two stages: the constant current fast charging phase and the reduction of the constant voltage current. At the constant current fast charging stage, the battery voltage gradually increases to the standard voltage of the battery, and then transferred to the constant voltage phase under the control chip, the voltage no longer increases to ensure that it will not be overcharge. To the set value, and finally the charging is completed. Electricity statistics chips can sample the battery power by recording the discharge curve. After the lithium -ion battery is used multiple times, the discharge curve will change. Although there is no memory effect in the lithium -ion battery, improper charging and discharge will seriously affect the battery performance.
