The reason why lithium batteries (charging) need to be protected by it is determined by its own characteristics. Since the material of the lithium battery itself determines that it cannot be charged, over -the -LE, overcurrent, short -circuit, and ultra -high temperature charging and discharge, lithium battery lithium battery components always follow a delicate protective board and a current insurance device. The protection function of lithium batteries is usually completed by the protection circuit board and PTC. The protective board is composed of electronic circuits. In the environment of -40 ° C to+85 ° C, accurately monitor the voltage of the battery and the current of the charging loop. Control the flow of the current circuit; PTC prevent bad damage to the battery under high temperature environment.
Protective boards usually include control IC, MOS switches, resistors, capacitors and auxiliary devices NTC, ID memory, etc. Among them, control IC, control the MOS switching of MOS switches in all normal circumstances, and communicate the lithium battery cell battery cells with external circuits. When the battery cell voltage or circuit current exceeds the specified value, it immediately controls the MOS switching of the MOS switching. Broken, protect the safety of the cell. NTC is the abbreviation of Negative TemperatureCoefficient, which means negative temperature coefficient. When the ambient temperature rises, its resistance value is reduced. Use electric equipment or charging equipment to respond in time, control internal interruptions to stop charging and discharge. ID memory is often a single -line interface memory. ID is an abbreviation of Identification, that is, the meaning of identity recognition, storage battery types, production date and other information. It can be limited to the traceability and application of the product.
