Defined in kWh, step_size multiplier: 1 Wh

FLAT

Flat fee without unit for step_size

PARKING_TIME

Time not charging: defined in hours, step_size multiplier: 1 second

"ENERGY"

PriceComponent

type
required
string <enum> (TariffDimensionType)
Enum Description
ENERGY

Defined in kWh, step_size multiplier: 1 Wh

FLAT

Flat fee without unit for step_size

PARKING_TIME

Time not charging: defined in hours, step_size multiplier: 1 second

TIME

Time charging: defined in hours, step_size multiplier: 1 second. Can also be used in combination with a RESERVATION restriction to describe the price of the reservation time.

The dimension that is being priced.

price
required
number

Price per unit for this dimension. This is including or excluding taxes according to the tax_included field of the Tariff that this PriceComponent is contained in.

vat
number

Applicable VAT percentage for this tariff dimension. If omitted, no VAT is applicable.

step_size
required
integer

Minimum amount to be billed. That is, the dimension will be billed in this step_size blocks. Consumed amounts are rounded up to the smallest multiple of step_size that is greater than the consumed amount. For example: if type is TIME and step_size has a value of 300, then time will be billed in blocks of 5 minutes. If 6 minutes were consumed, 10 minutes (2 blocks of step_size) will be billed.

The step_size field is no longer present in OCPI 3.0. In OCPI 3.0, Parties are advised to measure quantities as precise as required by calibration law and use the full precision of such measurements in cost computation. Users of OCPI 2.2.1 looking to be ready for a transition to OCPI 3.0 or to maximize interoperability with OCPI 3.0 are advised to effectively avoid using step_size by setting step_size to 1 always.

Maximum power in kW, for example 20. When the EV is charging with less than the defined amount of power, this TariffElement becomes/is active. If the charging power is or becomes higher, this TariffElement is not or no longer valid and becomes inactive. This describes NOT the maximum power over the entire Charging Session. This restriction can make a TariffElement become active when the charging power is below this value, but the TariffElement MUST no longer be active when the charging power raises above the defined value.
