库仑计数燃料测量系统的精度评价

摘要：库仑计数燃油压力表的许多用户认为，在％的误差精度。这将是方便，但一个百分比数字的有效性取决于许多变数，许多外直接控制燃油表。软件补偿因素的贡献来衡量的准确性，但根据应用程序。重要的是递过来补偿算法的数据是准确的。没有足够准确的输入数据，计量精度差，必然导致的。从这个角度来看，它有助于了解在燃油计量硬件本身的误差来源。

APPLICATION NOTE 485
Evaluating Accuracy of Coulomb-Counting Fuel-Gauging Systems

Abstract: Many users of coulomb-counting fuel gauges think of accuracy in terms of percent error. This would
be convenient, but the usefulness of a single percentage figure depends on numerous variables, many outside
the immediate control of the fuel gauge. Software compensation factors contribute to gauge accuracy, but
vary according to the application. It is important that the data fed to compensation algorithms be accurate.
Without sufficiently accurate input data, poor gauging accuracy will surely result. From this standpoint, it's
helpful
