Data and API

Updated 2026-09-20

ChargeMap joins two datasets: the Supercharger network as tracked by the supercharge.info community, and a hand-verified matrix of which EVs can use it. Both are free to read and build on.

Supercharger sites

3,537 sites in the US and Canada with coordinates, stall counts, rated power, hardware generation (V2, V3, V4), connector counts (NACS, Magic Dock CCS1, legacy Tesla) and the open-to-non-Tesla flag. Source: supercharge.info, refreshed every 12 hours.

GET https://chargemap.buzz/api/sites

Vehicle compatibility

38 brands and 114 models with per-model-year port type (NACS, CCS1, CHAdeMO, none), brand access status and date, and approved adapter with price. Curated from manufacturer press releases; verified 2026-09-19. Sources are listed in the project repository notes.

GET https://chargemap.buzz/api/compat?brand=volkswagen&model=id-buzz&year=2025 returns the answer, the summary counts and, with &sites=1, every site tagged go / adapter / no for that car. Call it with no parameters to list ids.

For AI assistants

llms.txt is the short index; llms-full.txt is the full brand-by-brand knowledge base in Markdown, regenerated with the data.
