What is EVcoder? EVcoder is a parts identification platform for electric vehicles. It maps any VIN, OEM part number, or vehicle model — including Chinese EV brands such as BYD, Wuling, AITO, Zeekr and XPeng — to the exact parts that fit, with 2.4 million spare parts indexed across 82 brands, exploded parts diagrams, and data updated daily. Independent repair workshops, parts distributors and EV importers use it to identify, cross-reference and source EV parts. In industry terms it is an EPC (electronic parts catalog) specialized for EVs.
Three ways in

Start from whatever you have in hand

Whether it's a VIN on the windshield, a number on the part label, or just the car in your bay — get to the exact part and its diagram.

Parts by VIN Number

Paste or scan a 17-digit VIN to get brand, model, trim, battery, motor and market spec — then jump straight to the parts list and diagrams for that exact configuration.

Look up parts by VIN →

Part Number Lookup

Enter an OEM part number to see what it fits, which numbers it supersedes, and cross-reference compatible alternatives across brands and model years.

Look up a part number →

Parts Catalog & Diagrams

Browse brand → model → trim → system → part, with exploded parts diagrams. High-voltage components — battery packs, BMS, drive motors, OBCs, charging ports — fully covered.

Coverage

Every major Chinese EV brand — covered at trim level

Overseas buyers search Chinese EVs by export name and Chinese name alike. EVcoder indexes both, so "BYD Atto 3" and "Yuan PLUS" lead to the same parts data.

Why EVcoder

Built where the general parts catalogs stop

  • High-voltage depth. Battery packs, BMS units, drive motors, on-board chargers, DC/DC converters and charging ports — the components ICE-era catalogs were never designed to cover.
  • Trim-level accuracy. 9,682 model-and-trim configurations, so "which battery fits this car" has one answer, not five.
  • Exploded parts diagrams. See how each assembly comes apart before you order a single bolt.
  • Dual naming. Export names (Atto 3) and Chinese domestic names (Yuan PLUS) resolve to the same parts data.
  • Updated daily. New models, new trims, new OEM part numbers as factories release them.
  • Free to identify. No paywall on the lookup itself — built for volume, not gatekeeping.

Who uses EVcoder?

  • Independent workshops servicing Chinese EVs without dealer tools
  • Auto spare parts dealers & exporters quoting Chinese EV parts across borders
  • Fleet & leasing operators standardizing parts data across mixed EV fleets
  • Importers & resellers verifying fitment before purchase

FAQ

Common questions

How do I find the right part for my car?
Three ways: search by VIN for an exact trim match, look up the OEM part number printed on the part, or browse the parts catalog by brand, model and system. EVcoder supports all three, free.
Does EVcoder cover Chinese EV brands?
Yes — Chinese EV brands including BYD, Wuling, AITO, Zeekr, XPeng, NIO and Li Auto, down to trim and model-year level, with both export names (Atto 3) and Chinese names (Yuan PLUS) indexed.
Are parts diagrams included?
Yes. The catalog includes exploded parts diagrams by system — battery, drive unit, charging, thermal, brakes, body and interior — so you can see how components assemble before ordering.
Can I identify a part with only the car, no part number?
Yes. Enter the VIN or pick brand → model → trim, then browse by system to find the part and its OEM number.
