7.7. Setting BCIBAT# parameters

7.7.1. Procedure to set the battery ID

1. Choose the bat_ID resistor (ohms) = RID from a table that maps battery capacity
range to a resistance.
2. Calculate the expected ADC reading. ADC4 = RID*.01*1023/1750.
3. Calculate <id_low> = (1023/1837.5) x (0.99 x RID) x 0.008 - 2; 0 if none
4. Calculate <id_high> = (1023/1662.5) x (1.01 x RID) x 0.012 +2; 1023 if none
5. Enter AT$BCIBAT#: <>,<>,<>,<>,<>,<>,<id_low>,<id_high>.
6. Enter AT$RESET: Reset the device, so changed parameters will take effect.
7. Read AT$BAT <>,<bat_id>.
8. Verify bat_id = # of the BCIBAT# corresponding to the range: <id_low>-<id_high>.

7.8. Setting BCITMP# parameters

7.8.1. Scope

Setting the BCITMP# parameters needs to be done by the customer, for each battery with a
thermistor installed. If no thermistor is installed in a battery, set all nine adc parameters to 0.
This is a one-time system level design, no factory-level production test or calibration is required.
