EPC Catalogs for Chinese Car Brands: Chery, Geely, BYD, GWM

The main Chinese EPC systems

The headline brands and the sub-brands their catalogs cover:

• Chery EPC: Chery, plus Exeed, Omoda, Jaecoo and Jetour
• Geely EPC: the Geely range, with links to its wider group
• GWM EPC: Great Wall, Haval, ORA, Tank and Wey
• BYD: the fast-growing EV maker, now sold in dozens of markets
• SAIC EPC: MG and related models

Why these catalogs feel different

Model cycles move quickly, sub-brands multiply, and the same platform can appear under several names across markets. That makes VIN-level identification more important here than almost anywhere, because matching by badge alone is unreliable when one car wears different names in different countries.

Why coverage is a competitive edge

As these brands' parc grows, the workshops that can already identify their parts accurately win the service work. Many independents still turn these cars away or guess. Online access removes the barrier of sourcing each maker's catalog separately, so you can quote a Chery or a BYD as confidently as a Golf.

Find the group before you look for the badge

This is the mistake that wastes the most time. European and Japanese habits say one badge means one catalog, and the Chinese groups do not work that way.

Omoda, Jaecoo and Exeed are Chery Group brands running on Chery numbering. Haval, Tank, Ora and Wey belong to Great Wall and share GWM data. Geely spans several marques on group data again. A workshop searching for an "Omoda catalog" as if it were an independent manufacturer finds nothing and concludes the data does not exist, while the part sits waiting under the group.

The numbering is easier than it looks

Many Chinese numbers follow the national assembly-group convention, where the leading digits identify the system rather than the model. 3501 is the brake group, 1109 is air intake, 3801 belongs to instrumentation. A Great Wall number such as 3501100-K00 announces itself as a brake component before you know anything else about the car.

Chery puts the platform first instead, so T11-3501080 reads as platform then group. BYD prefixes with the brand. Once you can read those leading digits, a supplier quote either matches the part you asked for or it visibly does not, which is the same fast check a VAG number gives you through its middle block.

The EV angle

Several Chinese leaders are EV-first, BYD above all. That shifts the critical assemblies to the high-voltage system: battery modules, power electronics and thermal loops. A proper EPC documents those groups, which generic aftermarket lookups rarely do.

BYD is worth singling out because it manufactures its own cells and much of its own electronics rather than assembling bought-in modules. The aftermarket alternatives that exist for a fifteen-year-old diesel simply have not appeared here yet, so the group catalog is usually the only route to a high-voltage part rather than the preferred one.
