    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.
