Industrial battery field reference

Full field reference for batteryCategory: "INDUSTRIAL_BATTERY" responses from GET /api/dpp/{slug}. Industrial batteries cover stationary energy storage, forklift batteries, data centre UPS systems, and grid-scale applications with rated energy content exceeding 2 kWh.

For fields shared across all categories, see DPP overview. This page documents what is specific to, or different for, industrial batteries.

Key differences from EV batteries

Industrial batteries share a similar field shape to EV batteries with two differences relevant to integrations:

1. Capacity scale — nominalCapacityKwh values for industrial batteries commonly run into hundreds or thousands of kWh. Do not assume kWh values below 10. Validate display formatting accordingly.

2. Recycled content thresholds differ — industrial battery thresholds apply from 2030 (not 2031 like EV batteries), and the lead threshold (85%) is significant because some industrial batteries use lead-acid chemistry.

Handling carbon footprint and efficiency

Both carbonFootprint and performance.roundTripEfficiencyPercent are guaranteed non-null for industrial batteries:

const dpp = await fetchDpp('my-industrial-battery-slug');

if (dpp.batteryCategory !== 'INDUSTRIAL_BATTERY') {
  throw new Error('Expected INDUSTRIAL_BATTERY');
}

// Both always present for INDUSTRIAL_BATTERY
const cf = dpp.carbonFootprint!;
const efficiency = dpp.performance.roundTripEfficiencyPercent;

console.log(`Carbon footprint: ${cf.totalKgCO2ePerKwh} kgCO₂e/kWh`);
console.log(`Round-trip efficiency: ${efficiency}%`);
console.log(`Capacity: ${dpp.performance.nominalCapacityKwh} kWh`);

// Display recycled lead prominently for lead-acid chemistry batteries
if (dpp.recycledContent.leadPercent > 0) {
  console.log(`Recycled lead: ${dpp.recycledContent.leadPercent}%`);
}

Annex XIII

Industrial batteries are specifically governed by Annex XIII of EU Battery Regulation 2023/1542, which defines the complete set of data fields that must be accessible via the battery passport. The Traceable data model is built to satisfy Annex XIII requirements.

See Annex XIII in the Compliance section for the full field-to-regulation mapping.
