Private Type 电池状态信息
外接电源状态 As Byte '没插=0 插了=1 无法取得信息=255
电池状态 As Byte '电量大于66%=1 电小于33%=2 小于5%=4 充电中=8 没有电池=128 无法取得信息=255
'以上说明似乎不对,以下是自己测试的:
'电量大于66%=1
'电量小于33%=???
'电量小于5%=???
'充电中=9
'没有电池=128
电池剩余电量 As Byte '0~100,若未知则为255
保留 As Byte '必须为0
秒为单位的电池剩余电量 As Integer '若未知则为-1
秒为单位的电池充满电的电量 As Integer '若未知则为-1
