Battery-electric passenger car manufacture

1. Scope and Applicability

This candidate PCR covers manufacture of new complete configured battery-electric passenger cars. It is narrower than CPC49113: exclude combustion-engine, hybrid and range-extender vehicles, public-transport vehicles, snow vehicles, golf cars, goods vehicles, spare parts and customer transport services. Identify model, VIN/options, body, installed traction-battery chemistry and constituent gate, drive layout, charging/control, wheels, seats, glazing, safety equipment and retained fluids. Include actual factory charging, dynamometer or short acceptance driving, leak tests, adjustments and rework with their attributable exchanges. Exclude customer driving, charging infrastructure delivery, maintenance, assumed service life and end of life. In measurement tables, unit means one complete accepted battery-electric passenger car; it is not a component, passenger-kilometre or payload unit.

2. Product Category Identity

Field	Value
canonical_pcr_id	pcr.metal-products-machinery-and-equipment.transport-equipment.passenger-car
classification_refs	CPC 3.0 49113; narrower context, no accepted mapping asserted
covered_products	New complete configured battery-electric passenger cars
excluded_products	Combustion, hybrid/range-extender, public-transport, snow, golf and goods vehicles; spares and transport services
representative_product	One accepted complete clean empty battery-electric passenger car of declared configuration
production_route	Receive stock and finished modules; actual body blanking/stamping, joining, aqueous preparation and liquid coating when inside gate; complete battery/drive/control/interior/chassis integration; factory charging, inspection and acceptance
market_state	New accepted complete vehicle at factory gate, no driver/passengers/payload; retained fluid and charge states declared; shipment protection separate

3. Reference Flow

Field	Value
What	Provide the declared complete battery-electric passenger car
How much	1 kg of the same complete accepted configured unit using measured net mass M
How well	Meet actual configuration-specific drawings and factory acceptance criteria; record battery/drive identity, insulation and electrical safety, charge function, steering/braking, installed restraint/control checks, glazing/closures and fluid/refrigerant leak checks as actually required, with calibrated instruments, test duration and results. Neither catalogue capacity nor historical plant announcements establish a generic test limit or manufacturing intensity.
How long or cycle	One manufacturing delivery; no assumed driving lifetime or transport-service cycle
reference_flow_link	finished_machine

Field	Value
Reference amount	1
Reference product flow	Complete configured battery-electric passenger car
Reference flow property	Mass 93a60a56-a3c8-11da-a746-0800200b9a66
Reference unit group	Units of mass 93a60a57-a4c8-11da-a746-0800200c9a66
Reference unit	kg
Required qualifiers	model and VIN/batch; options; installed traction-battery chemistry, capacity, serial and constituent gate; drive/charger/converter and control configuration; seats/wheels/glazing/safety equipment; installed and declared delivered accessories; empty clean state without driver/passengers/payload; retained coolant/brake fluid/refrigerant and charge state; measured M; site/reporting period; supplier and outsource gates; covered stages; acceptance criteria, charging meter and test duration

Weigh the same complete accepted clean empty unit on calibrated scales, including the installed battery, declared retained fluids and delivered accessories but excluding people, payload, transport protection and handling fixtures. M is this measured physical mass, not a catalogue value, legal curb-mass convention including a driver, or maximum gross vehicle mass. Kilogram normalization does not establish equivalent range, capacity, passenger transport performance or impacts across different configurations. The reference UUID remains unresolved because retrieved vehicle records have incompatible classification, route or reference property.

4. Measurement and Unit Rules

rule_id	Applies to	Required property	Required unit	Rule
reference_mass	reference product	Mass 93a60a56-a3c8-11da-a746-0800200b9a66	kg	M = accepted net mass of one complete unit of the same configuration in kg; collect using cp_mass.
vehicle_delivery_state	delivery configuration	Mass 93a60a56-a3c8-11da-a746-0800200b9a66	kg	Bind cp_mass to the same VIN/options, installed battery and retained-fluid/charge state. No driver, passengers, payload or handling tare enters M. Document removed transport protection separately; do not infer M from a legal curb-mass convention or catalogue weight.
energy_units	electricity rows	Net calorific value 93a60a56-a3c8-11da-a746-0800200c9a66	MJ	Preserve the meter unit; convert kWh to MJ using exactly 1 kWh = 3.6 MJ. Do not interpret the electricity property name as a combustion inventory.
volume_units	groundwater rows	Volume 93a60a56-a3c8-22da-a746-0800200c9a66	m3	Retain measured volume and its conditions; do not invent gas density, water density or calorific value to switch to mass or energy.

Process records are separate contributors to one final accepted output, not seven separately traded reference products. Retain traceable internal-part transfer and bill-of-material records; internal transfers cancel within this foreground and do not receive duplicated upstream burdens. The cards below are explicit route-conditioned exchanges. Add each actual additional part, chemical, fuel, packaging piece, wastewater stream or measured elementary substance as its own identified row; absence of a card is not a cut-off permission. For outsourced finishing, replace site chemistry and energy with the exact purchased service or finished-part record and disclose its coverage.

7. Allocation and Co-product Handling

rule_id	applies_to	rule	source_ids
direct_attribution	shared_operations	Use job tickets and submetering before allocation. Where a common meter remains, require a measured causal driver such as unit-hours for the identified operation, with all participating jobs and idle load disclosed; divide the attributable quantity by accepted units of the same configuration before mass normalization.	ghg-product-allocation-2011
coproduct_decision	saleable_outputs	Do not assume scrap is a co-product. Disclose destination and legal/product status. If multiple saleable co-products actually occur, seek subdivision; justify a physical relation or, when unavailable, documented economic/other allocation with sensitivity. No universal mass share or avoided-steel credit is prescribed.	ghg-product-allocation-2011
rework_scrap	manufacturing_losses	Retain rework and rejected-unit burdens attributable to the accepted reporting batch. Record recovered internal material once and exported wastes separately.

Calculation Rules

rule_id	Applies to	Formula or rule	Inputs	Output	source_ids
normalize_mass	all inventory rows	q_ref = q_item / M; q_item = exchange amount per one accepted finished unit; q_ref = exchange amount per 1 kg reference flow.	q_item; M; cp_mass	q_ref

The finished_machine output is fixed at 1 kg and is not divided again. Apply the conversion to each other applicable row using the same configuration and batch; quantity numerator units remain unchanged. Mixed configurations must be separated, not averaged by count with a catalogue mass.

Data Quality Requirements

requirement_id	Applies to	Requirement	Evidence
configuration_trace	all rows	Trace every input to installed BOM, route and accepted unit; supplier finished parts do not also receive raw-stock burdens. Disclose remaining components as missing coverage until separate atomic records are added.	drawings, BOM, supplier receipts
basis_quality	cp_mass	M must be positive measured net mass, with the same delivered configuration, fluid state and acceptance gate as all collected exchanges.	calibration and weighing records
coverage_quality	all processes	Document full batch temporal coverage, meter overlap, rejects, rework, stock changes, outsourced stages and unmeasured emissions. A missing record is unknown, not zero or not_applicable.	ledger, coverage matrix and measurement uncertainty
chemistry_quality	wet_surface; paint	Verify recipe, concentration and SDS for each supplied formulated chemical; characterize each outgoing waste stream and identify treatment separately from environmental emissions.	recipe, SDS, analyses and transfer tickets

9. Validation Rules

rule_id	applies_to	rule	source_ids
validate_reference	reference	Reject missing qualifiers, driver/payload-loaded, legal curb-mass convention or shipping-gross mass substitution, non-positive M or mismatch between configuration, cp_mass and finished_machine. Require 1 kg output and explicit normalize_mass on every non-reference applicable row.
validate_atomic	inventory	Require one physical exchange per row, verified public identity when supplied, correct property/unit, localized display and medium. Unresolved UUIDs do not authorize proxy substitution or mixed rows.
validate_balance	coverage	Reconcile installed mass, stock, waste, retained fluids and purchased parts using the actual BOM; independently reconcile installed pack/drive/charger constituent gates, retained fluids and VIN/options with the weighed vehicle. Reconcile charging losses and initial/final charge state without inventing a capacity credit; reconcile paint stocks, recovered solvent, sludge and actual speciated releases. Reconcile utilities by stage; internal transfers cancel. Explain differences against recorded measurement uncertainty, without a fabricated numerical tolerance.
validate_completeness	dataset	Check every conditional stage against route evidence. Require missing chemicals, parts, test media and actual emissions to be split and collected before claiming a complete inventory; prohibit cradle-to-gate or service comparisons while upstream or functional coverage is incomplete.
validate_allocation	shared_operations	Require complete driver records and justification for allocation and scrap treatment; document sensitivity where another defensible allocation may change results.	ghg-product-allocation-2011
