What are the SMBus and the SBS?
The Smart Battery System defines the parameters that are stored by an SBS-compliant
battery. These parameters include full battery status and fuel gauging information. The
System Management Bus is the language by which these parameters are communicated
between the battery, the charger and the host device.
How does the charger know what charge to deliver?
The CH5000 charger is capable of sensing and delivering an appropriate charge.
Upon inserting the battery into the charger, the battery communicates to the charger
over the SMBus telling the charger what type of cell chemistry it is and what type of
charge regime it needs. The CH5000 then configures its output to provide the charge
regime requested by the battery. If no SMBus communications are issued from the
battery, the charger interrogates the thermistor/resistor I.D. pin on the battery terminal
and delivers an appropriate charge.
FUEL GAUGE AND RECALIBRATION:
Fuel Gauge Operation
You may receive one of two different batteries with your LED headlight system. The
main difference between these two battery packs is the location and the function of the
battery gauge.
On one battery type (shown below), the LCD fuel gauge employs a 'five' segment LCD.
Each segment represents approximately 20% of the batteries remaining capacity. Each
segment of a fully charged battery represents approximately 30 minutes of run time. For
this battery, the LCD Fuel Gauge is located at the same end of the battery as the pull tab
and requires no actions to view it.
On the other battery type (example shown below), the LED fuel gauge employs a 'four' segment
LED. Each segment represents approximately 25% of the batteries remaining capacity. Each
segment of a fully charged battery represents approximately 37.5 minutes of run time. For this
battery, the LED fuel gauge is located on the front of the battery and the user is required to
