TI Fuel Tank Boosterpack with a 5000mAh Lithium Battery

Harry

I am using the element14 Fuel Tank Boosterpack code example provided to be used with the Tiva 123 Launchpad. The fuel tank boosterpack comes with a 1200mAh battery which is not enough got my application. I wish to monitor the mAh levels of a 5000mAh battery using the Fuel Tank Boosterpack.  Therefore I connected the 5000mAh battery instead of the default 1200mAh battery and experimented with the UART console provided via the Tiva MCU. It seems to me that the Fuel Gauge IC  BQ27510-G3 has not recognised the new 5000mAh battery. I would so much appreciate if someone can help me understand this issue. 

Does the fuel gauge IC  BQ27510-G3 need reprogramming to be used with a 5000mAh battery? If yes, what are the other TI tools I should order. 

Your responses are highly appreciated.

    Hi Amalinda,

    Are you able to access the data flash parameters of the gauge? In order to make the gauge function, you will need to configure several parameters of the gauge to suit your battery type. 

    -You need to program the correct chemical id on the chip to match your chemistry

    -you need to set your design capacity, terminate voltage, taper current and a list of other parameters as stipulated in the Technical reference manual of the device.

    I haven't used the booster pack before so you will need to figure out how to access the data flash of the gauge using it.

    thanks
