Implementation and Optimization for Battery Management in Terminal Based on Embedded Windows CE

介绍了对嵌入式Wince系统中电池驱动的优化。详细描述了使用UCB1400的10-bitADC对设备电池电压采样值的获取,通过增加电池电压的采样点数、电池电压值的归一化以及完善电池电压百分比算法来校正电池电量,并设置电压阈值进行简单的电源管理。测试结果表明,校正后的电池电量与实际值非常接近,并且在移动设备中运行效果良好。

This paper introducing the battery driver＇s optimization in embedded Wince system. Detailed described to obtain the samples by the 10-bit ADC of UCB1400. correcting the coulomb by increasing the samples,returning the voltages to one and revising the arithmetic about the percent of battery voltage. And set up the voltage boundary to do power management. The results test that the coulomb is very approximate to the actual value after correcting, and running well in the mobile equipments.
