Top 3 C Programming Approaches

Let''s examine practical methods developers use:

1. Voltage-Based Estimation

Pros: Simple implementation Cons: ±5% accuracy range

 float read_voltage() { return analogRead(BATT_PIN) * REF_VOLTAGE / 1024.0; } 

2. Coulomb Counting

Used in 78% of industrial battery management systems (BMS):

• Tracks current flow over time
• Requires temperature compensation

3. Impedance Spectroscopy

Emerging method showing 2.3% better accuracy than traditional methods in recent studies.
