Electric Vehicle Parts Catalog & Diagrams

Brand → model → trim → system → part. 2.4 million spare parts with exploded diagrams, structured the way a workshop actually works. (Known in the trade as an EPC — electronic parts catalog.)

How is the EVcoder parts catalog organized? Every vehicle is a configuration: brand, model, trim and model year. Each configuration is broken into systems — battery & BMS, drive unit, charging, thermal, brakes, suspension, body, interior and electronics — and each system into parts with OEM part numbers, exploded diagrams, fitment notes and compatible alternatives. The result: 2.4M+ spare parts across 82 brands, with Chinese EV brands covered at trim level and updated daily.
