What is the purpose of the lithium-ion battery protection board?

The charging time is generally more than one hour, and it is impossible for people to stay by the charger and wait for the battery to be fully charged. It takes a long time for a function to automatically power off and no longer charge after the battery is fully charged. This is one of the uses of lithium-ion battery protection boards. 2. Over-discharge protection battery power is generally not recommended to be used to the end, because this will easily lead to battery over-discharge and damage the battery. At this time, the over-discharge protection function on the lithium-ion battery protection board is required to shut down the battery at a minimum value of voltage to prevent battery damage. 3. It is impossible for the short-circuit protection battery to be 100% perfect. There will always be a small part of the battery with an internal short circuit. At this time, the lithium-ion battery protection board will close the protection board within a few milliseconds. The battery is protected by the power page. 4. Over-current protection When the battery is in the discharge period, that is, in use, the protection board has a maximum current limit function. As long as the discharge current exceeds this current, the lithium-ion battery protection board will automatically shut down and cut off the power supply. , There is no corresponding excessive current, which protects the battery from damage.
