Do you have to use a Li-ion battery management chip to charge a Li-ion battery?
With a voltage regulator and so on can also manage the process of charging lithium batteries, do not necessarily have to use lithium battery management chip, for alternative circuits can be their own 555 and so on with the chip with a hole in the board or the copper-clad board to build the circuit.
For lithium battery battery management chip for battery charging and discharging of various properties such as, constant voltage mode, constant current mode, etc., these charging methods are good for the battery, the most important point is relatively safe.
Lithium battery management chip for the extension of battery life has a significant role. Because with the charging and discharging chip, the voltage, current have reached a controllable state, can effectively control the charging state of the various stages of charging.

Lithium battery charge management chip introduction
In recent years, lithium iron phosphate batteries have been widely used, such as high-power power tools, drills, lawnmowers, medical equipment, light electric vehicles and so on. Because the P-O bond in lithium iron phosphate crystals is solid, it is difficult to decompose, and will not collapse and heat up or form strong oxidizing substances like lithium cobalt oxide at high temperatures or when overcharged, so it has good safety.
Because lithium iron phosphate batteries are lithium ion batteries that use lithium iron phosphate as the cathode material, the cycle life of a standard charge reaches more than 2,000 times, and the theoretical life expectancy will reach 7 to 8 years. The widespread use of lithium batteries, some products on the battery capacity of the demand continues to rise, it is necessary to series connection of multiple lithium batteries, which leads to the total voltage of the battery increases, and thus gave birth to the lithium battery charge management chip SNC201.
Electronics of such a chip can effectively manage the charging of each lithium battery, it will be based on the lithium battery's characteristics of the automatic pre-charging, constant-current charging, constant-voltage charging.
We all know that when there is no charge management chip directly to the lithium battery connected to the power supply charging, lithium batteries in the case of low power, suddenly enter the high current, will lead to damage to the lithium battery, because the current is large, the heat is also fast, the battery's life will become shorter, lithium batteries in addition to the fear of low power, but also afraid of overheating.
