device-chemistry:
type: string
description: 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.
enum:
- "nickel-cadmium"
- "nickel-metal-hydride"
- "lithium-ion"
- "lithium-ion-polymer"
- "lithium-ion-iron-phosphate"
- "lithium-ion-manganese-oxide"
ocv-capacity-table-0:
type: array
description: |
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.
