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。Maxim>AppNotes>BatteryManagementKeywords:batterycell,capacity,voltagemeasurement,coulombcounting,batteryfuelgauge,fuelgauge,May21,2002voltage-basedfuelgauge,batterycapacitymeasurementAPPLICATIONNOTE121InaccuraciesofEstimatingRemainingCellCapacitywithVoltageMeasurementsAloneAbstract:Implementingabatteryfuelgaugecanbedoneinavarietyofwaysincludingusingvoltagemeasurementsorcoulombcounting.Althoughtheuseofvoltagemeasurementhasbeenapopularmethodofchoice,itdoesnotproducethemostaccurateresultsavailable.Thisapplicationnotestudiesthevoltage-basedmethodoffuelgaugingforbothLi-IonandNiMHbatterycells.Dataisprovidedthatdemonstratesthehighdegreeoferrorintroducedwhenimplementingvoltagem……
