battery Cross-platform, normalized battery information library. Gives access to a system independent, typed battery state, capacity, charge and voltage values recalculated as necessary to be returned in mW, mWh or V units. Currently supported systems: Linux 2.6.3 803B 9+ OS X 10.10+ Windows XP+ FreeBSD DragonFlyBSD NetBSD OpenBSD Solaris Installation $ go get -u github.com/distatus/battery Code Example package main import ( "fmt" "github.com/distatus/battery" ) func main() { batteries, err := battery.GetAll() if err != nil { fmt.Println("Could not get battery info!") return } for i, battery := range batteries { fmt.Printf("Bat%d: ", i) fmt.Printf("state: %s, ", battery.State.String()) fmt.Printf("current capacity: %f mWh, ", battery.Current) fmt.Printf("last full capacity: %f mWh, ", battery.Full) fmt.Printf("design capacity: %f mWh, ", battery.Design) fmt.Printf("charge rate: %f mW, ", battery.ChargeRate) fmt.Printf("voltage: %f V, ", battery.Voltage) fmt.Printf("design voltage: %f V\n", battery.DesignVoltage) } } CLI There is also a little utility which - more or less - mimicks the GNU/Linux acpi -b command. Installation $ go install github.com/distatus/battery/cmd/battery@latest Usage $ battery BAT0: Full, 95.61% [Voltage: 12.15V (design: 12.15V)]
