Overview
The Core CNT Daily KPIs is a Certified Product Point Template for Battery Containers that defines required normalized real-time performance calculations that scale, or transform several of the points in the Core Monitoring KPIs. These points are required for the Bazefield installation to function properly across all core applications.
These calculations specifically translate OEM-specific signals into consistent indicators of operational state, availability, communication status, and event conditions. By abstracting vendor-specific complexities, the Core CNT Daily KPIs enables unified fleet monitoring, reduces configuration overhead, and supports consistent reporting and alarm management across heterogeneous battery containers technologies.
The Core CNT Daily KPIs template defines 7 daily aggregation calculations for Battery Containers. These KPIs roll up hourly metrics into daily summaries for data quality, energy throughput, equivalent full cycles, and round-trip efficiency.
Template Definition
The Core CNT Daily KPIs is defined below. Calculations are one of the following types:
Scale Equations — Algebraic or logical manipulations of input data done on the Bazefield edge buffer
Online Expressions — Algebraic or logical manipulations of input data done on the central Bazefield data engines (typically on a storage node). Similar to scale equations in purpose, but done in the centralized architecture.
Interval Expressions — Algebraic, logical, or advanced manipulations of input data done within a pre-defined aggregation interval (e.g. 5 minutes, 10 minutes, 1 hour, etc). These are typically done centrally on a storage node.
Details on the Point Names, Descriptions, and Types are below.
Required for Bazefield Core Dashboard functionality
Optional for common additional data streams/sources
Calculation Definition Table
Name | Description | Type | Interval | Units | |
|---|---|---|---|---|---|
DCDataCoverageDaily | Daily average of hourly DC Power data coverage for the container | Calculation (Interval Exp.) | Daily | % | |
DailyEnergyCharged | Daily total energy charged to the container | Calculation (Interval Exp.) | Daily | kWh | |
DailyEnergyDischarged | Daily total energy discharged from the container | Calculation (Interval Exp.) | Daily | kWh | |
EquivalentFullCycles | Daily equivalent full cycles. Total energy throughput (charged + discharged) divided by 2 and normalized by rated energy capacity. Requires energyCapacity attribute. | Calculation (Interval Exp.) | Daily | — | |
OverallDataQualityDaily | Daily overall data quality score as equal-weighted average of DC Power and State of Charge data coverage | Calculation (Interval Exp.) | Daily | % | |
RoundTripEfficiency | Daily SOC-normalized round-trip efficiency of the PCS (IEEE 2686-2023). Adjusts for net SOC change using TotalStoredEnergy so partial cycles do not distort efficiency. | Calculation (Interval Exp.) | Daily | % | |
SOCDataCoverageDaily | Daily average of hourly State of Charge data coverage for the container | Calculation (Interval Exp.) | Daily | % |
