Battery protection is nothing more than protection that meets the protection conditions.
Overcharge protection: it is necessary to check the voltage matching of the charger. Generally speaking, the voltage of the charger should be less than or equal to the charging limit voltage. Each type of battery has relevant regulations.
Discharge protection: when the client use to put protection should not be happened, after the discharge protection is, in general the protection of the 2.5 V voltage of the battery, the use of used electrical appliances minimum voltage should be 3.0 V or more, cannot be used each time the battery discharge voltage protection is the right of use the battery.
Charge overcurrent protection: Generally speaking, the charger's current is greater than the battery's charge overcurrent protection value and the protection occurs, which belongs to the matching problem between the two.
Discharge overcurrent protection: generally speaking, the battery protection is caused by the larger starting current of the electrical equipment. This is necessary to take into account the redundancy of the battery overcurrent at the beginning of the design, and it needs to be provided to the battery design manufacturer in order to avoid the occurrence of overcurrent protection. If the type is the ratio of the battery need to provide the ratio of continuous discharge current, the electric current and there is a difference between the maximum discharge current of batteries, battery discharge current largest means can be discharge in the electrical flow, rather than continue to discharge, for continuous discharge are a large amount of hot problems to solve, design to have larger redundancy design.
Short circuit protection: if there is a short circuit protection, it is necessary to find out the reason, to avoid repeated short circuit protection sent, the short circuit protection of accident, need to remove the short circuit protection before normal assembly and use; If the battery is short circuit protection in the process of equipment and equipment, the battery needs to be removed, and after removing the short circuit protection, it can be assembled again. The general method to remove the short circuit is to charge.
