Dfuel_gauge.rst6 The fuel gauge subsystem exposes an API to uniformly access battery fuel gauge devices. Currently,
20 Fuel gauges typically support multiple properties, such as temperature readings of the battery-pack
21 or present-time current/voltage.
29 Battery Cutoff
32 Many fuel gauges embedded within battery packs expose a register address that when written to with a
33 specific payload will do a battery cutoff. This battery cutoff is often referred to as ship, shelf,
34 or sleep mode due to its utility in reducing battery drain while devices are stored or shipped.
36 The fuel gauge API exposes battery cutoff with the :c:func:`fuel_gauge_battery_cutoff` function.
