为了减少海洋污染,充分利用绿色能源,研究了太阳能电池板的特性。设计了利用单片机控制的太阳能充放电控制器,对部分电路进行仿真测试。通过太阳能电池板的输出特性,找到了适合太阳能电池板的最佳输出电压及电流。利用上限及下限值设置,在单片机中通过程序控制电路是否充电。将船舶直流电源改为利用太阳能,绿色环保。I...
ADC的校准 1)根据原理图,对于ADC的校准主要利用了ADC0和ADC3这两个模数转换通道(分别对应电池VBAT和Charge端,其余两个通道的值校准后直接用ADC0的校准参数,不单独做校准。 2)校准的过程:先控制电源供电电压分别为3.4V和4.2V,则可以得到两个对应的ADC值,根据这两组...
