Battery protection scheme is a kind of high and new technology and complex system, it involves all kinds of protection function, can according to need to design hardware and software control and communication function: 

- charging voltage protection; 

- charging pressure lifting; 

- discharge voltage protection; 

Remove - discharge voltage; 

- overcurrent protection; 

- short circuit protection; 

- balance charge management; 

- the battery temperature detection; 

- the remaining capacity detection; 

- defect battery analysis and warning system; 

- charging temperature compensation system; 

- communication interface: PowerLAN, SMBus and so on. 

According to the practical application and the cost consideration, we can use some foreign well-known battery management solutions, such as Seiko, Ricoh, TI, and Analog, and so on.
