Structual Drawing of Smart Battery Pack
 
   We are able to supply such SMBus battery pack for many years,it's a battery system includes intelligence to allow the battery system to control various aspects of the charging and discharging of the battery, as well as to constantly monitor the battery voltage,temperature,current charge/discharge rate, and remaining capacity of the battery. Now more and more portable electronic equipments are looking for the SMBus battery pack.
 
   SMBus(Smart Battery System Block Diagrams)---For each battery,three connections must be made----Power (the battery's positive and negative terminals), the SMBus(Clock and Data) and the Safety Signal(resistance). Additionally, the system host must be able to query any battery in the system.
Battery Model£ºHYLB-850
Li-ion Rechargeable Battery Pack
Volt & Capacity£º11.1V 4400mAh
Pack Configuration£º3S2P,18650 2200mAh
A.PCM
This electronic protection device is used to protect the battery over-charging,over-discharging and short-circuit¡£
B.Poly Switch Device£¨PTC£©
This device can protect the li-ion battery from high voltage current when short-circuit happens.
C.Thermal Fuse
It protects the battery by self-shorting the fuse when the battery temperature rises over 90C to prevent overheating and potential hazard in the events of over-charging, over-discharging or short-circuit that causes the battery's temperature to rise irregularly¡£
D.Temperature Sensor£¨NTC£©
We use it to protect the over-heat danger.
E.Battery Pack Cell :18650 Li-ion cell
F.MOSFET (Protection IC)
This MOSFET can detect and protect the li-ion battery from the damage caused by overly high voltage and overly low voltage, it plays a key work on the switch on-off in the electronic circuit to keep the volt stable.
G.Power Management IC (BQ2085£©
This Power Management IC monitors the operation status of the battery.It accurately calculates and indicates the battery's capacity with each charging,re-charging or using of the battery.
