Overview
The Core Real-Time Calculations 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 Real-Time Data. 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 Real-Time Calculations enables unified fleet monitoring, reduces configuration overhead, and supports consistent reporting and alarm management across heterogeneous battery containers technologies.
The Core Real-Time Calculations template defines 27 calculations for Battery Containers. These calculations derive operational state, charge/discharge status, communication health, rack availability tracking, and data quality indicators from raw container data.
Template Definition
The Core Real-Time Calculations 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
