Data and assistant tools

The comparison tables and checkers use the records below. The JSON includes the source records and the derived fields needed by the checkers. The generated field is the build date; every record carries its own checked dates, and a build date is not a verification date.

The four onboard charger evidence cards are a separate companion collection published on the page, outside the 16-model JSON charger collection. Their pairing statements and vehicle evidence must be read with their scope and sources; they are not automatic compatibility answers.

• Batteries: 19 records. Capacity as an array of rated points, cycle life at a stated depth of discharge, charge limits, NCC listing with list version date.
• Appliances: 28 records. Published consumption figures, sizing basis, interlocks and blocking notices.
• Mains chargers: 16 records. Profiles per chemistry, lithium profile present or absent, selection method.
• DC-DC chargers: 6 records. Output, input window, trigger, smart-alternator and lithium statements, link to the maker’s cable and fuse table.
• Split charge relays: 6 records.
• Base vehicles: 16 records. What the vehicle maker publishes about alternator charging behaviour, or the absence line.
• Rules: 30 records. The claims ledger: every number a checker applies, with evidence grade, source, clause and jurisdiction, including rules recorded as not implemented.
• Merchants: programme status for every retailer linked.
• Checker dataset: the single file the browser checkers fetch.

Across the product collections there are 172 recorded absences, each with the document that was checked and the date.

Field meanings

From 21 September 2026, the charger and checker-dataset envelopes use schema_version: "2.0": output_a can be null when ratings are unresolved. Consumers must check output_status and output_note, and follow output_evidence_card for both document scopes. Null is not zero and must not be used in a current comparison. Other dataset envelopes retain version 1.0.

sources[]

One entry per field group. evidence is the grade (standard, manufacturer, scheme, convention, secondary, unverified). quote is verbatim. checked is the date the document was read. hosted_by: distributor flags a maker’s document read on a distributor server.

sources[].absent

True when the document was checked and does not state the field. Rendered as “No published [figure] found (checked [date])”. Never a negative claim.

gaps[]

The field groups the maker does not publish. Each has a matching absent source entry.

capacity_ratings[]

Every rate the maker publishes. rate: unstated means the maker gives a number with no rate; do not assume C20.

cycle_life[]

Only recorded with dod_pct and eol_criterion. A cycle count without both is not a fact.

dod_guidance

The maker’s own depth-of-discharge guidance. published: false renders the absence line.

ncc.list_version_date

Which NCC list a figure came from. The March 2024 list dropped the capacity and cycle columns. rate_basis_published is always false: the scheme does not state the discharge rate.

sizing.basis

How the checker uses an appliance figure: published average, Ah/h at a stated ambient, Ah per 24 h, published range, rated upper bound, reader-entered, or inverter.

sizing.interlock / blocking_notice

Text the checker must show; an interlock excludes a figure from the total, a blocking notice is shown before any number.

lithium_profile

published, absent (renders the absence line) or published_but_unspecified.

rules: implemented

False for rules the checker does not apply (unverified, secondary, or kept as reference evidence); not_implemented_reason says why.

retailers[].affiliate

False until a programme has approved the live site. Tags never appear in the data.

Browser tools (WebMCP)

Where the browser supports it, four read-only tools are registered on the checker pages: size_leisure_battery, charging_method, list_products (paged envelope with schema_version: "2.0", total, returned, offset, limit, has_more, next_offset, records, disclaimer) and glossary_lookup. Battery inputs are validated by the same rules as the visible form; invalid active fields return errors. Active 230 V loads require inverter_on_hours_per_day, from 0 to 24 and at least the longest active AC-load duration. Results retain relevant inputs and assumptions so the calculation can be checked. There is no cable-sizing or whole-system current-capability tool.
