Financial & Logistic Battery Solution

In recent years, due to rapid development of lithium battery, remaining battery capacity on portable products has been evaluated by voltage measurements, however, their relationship varies according to discharge rate, temperature and battery’s aging degree. In this way, error rate can reach 50%. Because of growing market demand for longer use time, more precise solutions are required during design. Using smart battery fuel gauge IC to measure battery’s charge or discharge capacity is ableto precisely evaluate battery level.

PCM: a protection circuit designed mainly for rechargeable smart battery pack. Because of chemical characteristics of lithium battery, protection functions like smart battery level calculate, over charge, over discharge, short circuit, over current, etc, should be provided to avoid fire and explosion.

Protection IC: constantly monitors cells’ over charge, over discharge, short circuit, and over current to ensure cell’s safe, stable and efficient work.

Over current protection (PTC): mainly target for secondary protection function. PTC can recover fuse and has dual functions of over current protection and auto recovery. PTC can avoid battery from over heat discharge and occurrence of unsafe high current.

MOSFET: play the role of switch during circuit protection to guarantee load voltage can neither rise nor drop.
