EnergyResourceStorage
Typed energy resource schema for storage DERs: battery energy storage systems (BESS), EV chargers, and vehicle-to-grid (V2G) capable chargers.
EnergyResourceStorage is one of the seven composable kinds that make up EnergyResource in the ElectricityCredential. It is the only kind that carries storageCapacityKwh.
Canonical IRI: https://schema.nfh.global/EnergyResourceStorage/v1.0
CIM alignment: cim:BatteryUnit (BESS/BATTERY), cim:ElectricVehicleChargingStation (EVCHARGER/EVV2G) — IEC 61970-302

Versions
| Version | Status | Notes |
|---|---|---|
| v1.0 | Current | Initial typed kind for storage DERs, extracted from ElectricityCredential/v1.2. storageCapacityKwh replaces energyCapacityKwh from EnergyResource v1.1. Adds stateOfHealthPct, maxChargeRateKw, maxDischargeRateKw. BATTERY deprecated in favour of BESS. |

Type discriminators
type value | CIM class | Notes |
|---|---|---|
BESS | cim:BatteryUnit | Preferred; replaces deprecated BATTERY |
BATTERY | cim:BatteryUnit | Deprecated — use BESS |
EV_CHARGER | cim:ElectricVehicleChargingStation | Unidirectional charger |
EV_V2G | cim:ElectricVehicleChargingStation | Bidirectional, vehicle-to-grid capable |

v1.1 → v1.2 migration note
energyCapacityKwh (on the common attributes in EnergyResource v1.1) was renamed to storageCapacityKwh and restricted exclusively to this kind.
