device-chemistry

string

 
This describes the chemical technology of the battery. The "lithium-ion" value is a blanket type for all lithium-ion batteries. If the specific chemistry is unknown, this value can be used instead of the precise "lithium-ion-X" options.

This property is required.

Legal values: 'nickel-cadmium', 'nickel-metal-hydride', 'lithium-ion', 'lithium-ion-polymer', 'lithium-ion-iron-phosphate', 'lithium-ion-manganese-oxide'

ocv-capacity-table-0

array

 
An array providing the open circuit voltage (OCV) , which is used to look
up battery capacity according to current OCV value. The OCV unit is
microvolts.

Unlike the linux equivalent this array is required to be 11 elements
long, representing the voltages for 0-100% charge in 10% steps.

This property is required.

re-charge-voltage-microvolt

int

 
limit to automatically start charging again

precharge-current-microamp

int

 
current for pre-charge phase

charge-term-current-microamp

int

battery-voltage

phandle

 
Device to read battery voltage from.

Device must implement the sensor API and provide the
`SENSOR_CHAN_VOLTAGE` channel.

This property is required.

battery-current

phandle

 
Device to read battery current from.

Device must implement the sensor API and provide the
`SENSOR_CHAN_CURRENT` channel.
