Time of Use
Assumptions
- TOU definitions are created corresponding to the required 'bins/buckets'
- A single Rate Period is created covering the whole year to which the TOU definitions are assigned
- A Billing Profile is created using that Rate Period definition
- Devices are put in the Billing Profile
- Devices can only be in one active billing group at a point in time i.e. billing surface
- The TOU definitions in the Billing Profile are submitted via device config to the charger whenever the Billing Profile is saved
- The TOU payload will include the timestamp of the last published Billing Profile version i.e. last time it was saved
- TOU definitions will be minified but maintain the TOU order used in the Billing Profile
- Final Accumlated KWH and Peak KW values from the previous 24hrs for each TOU bin will be reported back from each charger
- Reports may repeat the same values at intervals throughout the following 24hrs to ensure a successful data submission
- Accumulated energy will increase over time and not be reset by the charger
Energy usage deltas for each charger will be calculated by ZEFNET based on a given date/time range
- Peak KW will be reset to 0 on the charger at midnight every day
- The reporting parameter used to identify each bin will be 801, 802, 803 or 804, where 801=bin1, 802=bin2 etc
- Energy and KW will be concatenated with a '#' symbol to create a single log entry containing both values for later parsing
- A record will be created in the device-log table in AWS for each parameter supplied
