learn.whatIsHeading
Calculates time to fully charge a battery based on charger current and battery capacity. Helps optimize charging strategy.
공식
Basic time = capacity ÷ charger current
단계별 가이드
- 1Battery capacity in mAh
- 2Charger current in mA
- 3Basic time = capacity ÷ charger current
- 4Account for taper charging (slows at 80-90% full)
- 5Typical 20-50% penalty for taper
풀어진 예시
입력
2000mAh, 500mA charger
결과
4 hours
피해야 할 일반적인 실수
- ✕Assuming linear charge time (actual curve is non-linear)
- ✕Not accounting for charger efficiency (80-90% typical)
자주 묻는 질문
Should I use fast charging?
Fast charging reduces battery lifespan by 10-20%; use only when needed; standard charging preserves battery.
What's optimal charging speed?
C/10 (capacity ÷ 10) is safest; C/2 acceptable; >1C causes heat and reduced lifespan.
