18650 lithium-ion battery protection plate function, 18650 battery charging method. An important purpose of the 18650 lithium-ion battery protection board is to protect the battery and extend the battery life. The 18650 lithium-ion battery protective plate preparation process has been very mature, except for performance has greatly improved, its security is also very perfect.
According to the scientific 18650 battery charging method, economic benefits are reflected in the application. 18650 lithium-ion battery protective plate function battery overcharge protection: charge 18650 lithium ion battery, when the battery voltage charges the over-charge detection voltage (4.28 ± 0.
025V), protect circuit action, cut off the charging pathway, and realize overcharge protection. Battery Overlay Protection: When the load is discharged, when the battery voltage drops to the over-discharge voltage (2.3 ± 0.
08V), the circuit action, turn off the discharge path, and achieves overwork protection. Short-circuit protection function: When the output is short, the protection circuit will cut off the passage after the delay 320US, realize short circuit protection, and the circuit can automatically restore the output. Overcurrent protection function: When the output current exceeds the maximum current value of the set, the protection circuit will operate after the delay 10 ms, cut off the path, achieve overcurrent protection, after disconnecting the external load, the circuit can automatically restore the output.
18650 Lithium Ion Battery Protection Board Most of the steel shell package, the battery is not high, due to the no protection function, in the case of overcharge (excessive charging), the internal pressure increases, when exceeding the tolerance, Will explode. The short circuit, too high, or the battery is extruded or even piercing, etc. may cause the battery explosion.
In addition, some 18650 batteries are now self-contained, with overcharge and short-circuit protection, with high security performance. 18650 Battery charging method ● Do not fully charge the electricity for a long time, the so-called trickle charging About lithium-ion battery is to challenge the quality and accuracy of the charging protection circuit, often make the battery voltage exceed the standard voltage 0.1 volts, 4.
1 rose to 4.2 volts, then the life of the battery will be reduced. shorten.
However, the lithium-ion battery is easily activated, and the battery can be activated as long as it passes through 3-5 normal charge and discharge cycles, and normal capacity is restored. ● Control the limit temperature at the time of charging, try to prevent charging below 0 ° C, otherwise, it will seriously affect the battery life. ● The 18650 battery can be charged when the electricity is too low, without having to wait until the battery is placed in the termination voltage to avoid the occurrence of the pan.
The above is the 18650 lithium-ion battery protective plate function, 18650 battery charging method. The 18650 lithium-ion battery should depth discharge (i.e.
, exhausted) in the premise of no protective plate (ie, using the end), which helps the battery in the negative electrode to form a layer of protective film, and can charge and discharge at any time after 3-5 times. Can't be less than 3.0V, not higher than 4.
2V. Use it with a protective board.
