如何在Mac上获取电池信息？

Question

具体来说，我指的是电池健康状况，充电水平，电压。它看起来并不像现有的那样容易。有谁知道是否有一个简单的方法，如果没有，如何实现它？

Answer 1

我创建了一个名为SystemInfoKit的开源且易于使用的框架，以获取所有系统信息，CPU，内存和网络使用情况以及温度。

以下是获取所有电池信息所需的所有代码：

// At top of file
#import <SystemInfoKit/SystemInfoKit.h>

JSKSystemMonitor *systemMonitor = [JSKSystemMonitor systemMonitor];

JSKMBatteryUsageInfo batteryUsageInfo = systemMonitor.batteryUsageInfo;

NSLog(@"Battery Installed: %hhd", batteryUsageInfo.present);
NSLog(@"Battery Fully Charged: %hhd", batteryUsageInfo.full);
NSLog(@"Battery Connected To Charger: %hhd", batteryUsageInfo.acConnected);
NSLog(@"Battery Charging: %hhd", batteryUsageInfo.charging);

NSLog(@"Battery Voltage: %f V", batteryUsageInfo.voltage);
NSLog(@"Battery Amperage: %f A", batteryUsageInfo.amperage);

NSLog(@"Battery Design Capacity: %f mAh", batteryUsageInfo.designCapacity);
NSLog(@"Battery Maximum Capacity: %f mAh", batteryUsageInfo.maximumCapacity);
NSLog(@"Battery Current Capacity: %f mAh", batteryUsageInfo.currentCapacity);

NSLog(@"Battery Design Cycle Count: %lu Cycles", batteryUsageInfo.designCycleCount);
NSLog(@"Battery Cycle Count: %lu Cycles", batteryUsageInfo.cycleCount);
NSLog(@"Battery Age: %lu Days", batteryUsageInfo.ageInDays);

IOKit中的IOPowerSources功能可用于获取有关电池状态的信息。
