摘要
目前移动电源电量检测方案大多是通过对充放电电压、电流等参数进行采样来获得当前电量,然而电量检测又容易受到一些因素影响,比如温度、老化、负载问题。为避免由于这些因素导致移动电源出现较大的电量显示偏差,采用一种采样型移动电源电量计,通过监测比例电源容量来校准移动电源基准量,从而提高移动电源电量显示精确度。
At present,most of the power detection schemes of mobile power obtain the current power by sampling the charging and discharging voltage,current and other parameters.However,the power detection is vulnerable to some factors,such as temperature,aging,load problems.In order to avoid the large power displaying deviation caused by these factors,a sampling mobile power meter is used to calibrate the reference value of mobile power supply by monitoring the capacity of proportional power supply,so as to improve the accuracy of power displaying of mobile power supply.
