Smart Battery Pack
 
   Hengyu's advanced SMART battery packs communicate status to the portable device via an integrated circuit in the battery pack. This information might include: type, model number, manufacturer, characteristics, discharge rate, predicted remaining capacity, almost-discharged alarm, temperature and voltage. Hengyu has partnered with Texas Instruments to provide the most advanced fuel gauging with Impedance Track™ technology. Impedance Track™ calculates changes in impedance caused by battery age, temperature and cycle patterns to predict remaining run-time within 99% accuracy throughout the entire life of the battery. It maximizes system run-time by enabling use of the full chemical capacity available in the battery pack. Communication is delivered to the portable device via a communication bus (such as SMBus, I2C, or HDQ), and delivered to the user with LEDs .
 
   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.
