Hi,
We have a custom board using Bq35100pwr. We are using a Tadiran 19000mAh battery. We are able to communicate with the module and get voltage and temperature from it. We are having issues get the current and accumulator mode readings. Following are the steps
1. GE asserts high
2. Checks if battery capacity is set to 19000mAh if not set it to 19000mAh.
3. Set Battery Alert to 0x00.
4 Set Operation Config A to 0x00.
5. Enable Gauge for 30 seconds
6. Disable gauge
7. Wait for G_Done to be high.
8. Read voltage, temperature, current, and Accumulated capacity
In the last step, we are able to get correcting readings for voltage and temperature. But for current, the reading is coming out to be -75mA, whereas the device is consuming 15mA (measured using the current meter), and accumulated capacity, is reported approx 17732 which is also incorrect.
What are we missing?
