不准确的电压测量本身的剩余电池容量的估算

资料介绍
摘要:实现电池电量计,可以在各种不同的方式,包括使用电压测量或库仑计数。虽然电压测量的使用已成为流行的选择方法,它不会产生最准确的结果。本应用笔记研究锂离子电池和镍氢电池的燃料计量电压的方法。数据提供演示的高度出台实施燃油压力表的方法,当电池受到现实世界的条件,不同的温度和放电速率电压测量时的误差。

APPLICATION NOTE 121
Inaccuracies of Estimating Remaining Cell Capacity with Voltage
Measurements Alone


Abstract: Implementing a battery fuel gauge can be done in a variety of ways including using voltage
measurements or coulomb counting. Although the use of voltage measurement has been a popular method of
choice, it does not produce the most accurate results available. This application note studies the voltage-based
method of fuel gauging for both Li-Ion and NiMH battery cells. Data is provided that demonstrates the high
degree of error introduced when implementing voltage m
