| In the coming months, we will remove charging tariffs from CWO. Instead, CWO will request the price from EV Hub for sessions which will be calculated by EV's own price engine. |
Tariff definition for consumption-based charging
For consumption-based charging, the price should be calculated by consumed energy and not by time. Since the tariff engine cannot handle decimals, we need to work with a unit that is small enough to avoid decimals.
The consumption is charged by kWh, but the tariff engine should calculate by Wh, thus a factor 1000 smaller.
| Note: We might get rounding problems if the original tariff is specified with more than 3 decimals. This is by design today. |
