energy-full 與charge_full 之間的單位有什麼區別？

我有 2 種不同的最大電池能量結果：

upower -i $(upower -e | grep -i bar) | grep energy

energy:              18.061 Wh
energy-empty:        0 Wh
energy-full:         33.4021 Wh
energy-full-design:  50.7296 Wh
energy-rate: 7.30384 W

因此，upower據我所知，最大能量可能是 ~33.5 瓦*小時。但從cat /sys/class/power_supply/BAT0/{charge_full,charge_full_design}

/sys/class/power_supply/BAT0/charge_full:
2186000
/sys/class/power_supply/BAT0/charge_full_design:
3320000

我得到數字2186000，它是什麼單位？焦耳？但這與上面的不一樣33.5*60*60 == 120600J。那為什麼不一樣。什麼是energy-rate（7 瓦）？現在是電池性能嗎？

根據核心文件，這些值以 µAh（微安時）為單位：
