Frequently Asked Questions

How accurate is SouthChip fuel gauge technology?

SouthChip fuel gauges provide high accuracy battery monitoring: (1) Voltage accuracy - ±5mV typical for precise voltage measurement. (2) Current accuracy - ±1% after calibration with proper sense resistor. (3) SOC accuracy - 3-5% typical under steady-state conditions. (4) Impedance tracking - Compensates for battery aging and temperature, maintaining accuracy over battery lifetime. (5) Temperature compensation - Automatic adjustment for temperature effects on battery characteristics. (6) Calibration - Factory calibrated with runtime auto-calibration. The impedance tracking technology is more accurate than simple voltage-based fuel gauging, especially under load conditions and as the battery ages. For most consumer electronics applications, this accuracy provides excellent user experience with reliable battery level indication.

What parameters can SouthChip fuel gauges report?

SouthChip fuel gauges report comprehensive battery parameters: (1) State-of-Charge (SOC) - Remaining battery capacity as percentage (0-100%). (2) State-of-Health (SOH) - Battery health status indicating capacity fade. (3) Remaining capacity - Absolute remaining capacity in mAh or mWh. (4) Full charge capacity - Current maximum capacity accounting for aging. (5) Time-to-empty - Estimated time until battery depleted at current discharge rate. (6) Time-to-full - Estimated time to full charge at current charge rate. (7) Cycle count - Number of charge/discharge cycles accumulated. (8) Battery voltage - Measured terminal voltage. (9) Battery current - Charge/discharge current. (10) Battery temperature - From internal or external temperature sensor. These parameters enable sophisticated battery management, accurate runtime prediction, and proactive maintenance alerts.
