您可以从Win32_Battery课堂上获得所有这些 - http://msdn.microsoft.com/en-us/library/windows/desktop/aa394074(v=vs.85).aspx
class Win32_Battery : CIM_Battery
{
uint16 Availability;
uint32 BatteryRechargeTime;
uint16 BatteryStatus;
string Caption;
uint16 Chemistry;
uint32 ConfigManagerErrorCode;
boolean ConfigManagerUserConfig;
string CreationClassName;
string Description;
uint32 DesignCapacity;
uint64 DesignVoltage;
string DeviceID;
boolean ErrorCleared;
string ErrorDescription;
uint16 EstimatedChargeRemaining;
uint32 EstimatedRunTime;
uint32 ExpectedBatteryLife;
uint32 ExpectedLife;
uint32 FullChargeCapacity;
datetime InstallDate;
uint32 LastErrorCode;
uint32 MaxRechargeTime;
string Name;
string PNPDeviceID;
uint16 PowerManagementCapabilities[];
boolean PowerManagementSupported;
string SmartBatteryVersion;
string Status;
uint16 StatusInfo;
string SystemCreationClassName;
string SystemName;
uint32 TimeOnBattery;
uint32 TimeToFullCharge;
};

电池序列号
Dim results As String = ""
Dim batteryReturn As Management.ManagementObjectCollection
Dim batterySearch As Management.ManagementObjectSearcher
batterySearch = New Management.ManagementObjectSearcher("root\cimv2", "Select * from Win32_Battery")
batteryReturn = batterySearch.Get
For Each baseobject In batteryReturn
results += baseobject("DeviceID")
Next
Messagebox.show(results, "Battery serial:")

就像在 c# 中一样（如果你用谷歌搜索解决方案，不要搜索 vb，搜索 .net 甚至 c#）。见https://stackoverflow.com/a/8946096
（我会使用http://msdn.microsoft.com/en-us/library/system.windows.forms.powerstatus.aspx - 如果只有电源状态是相关的）
