Relay Product Catalog

Company Profile BYD Component Product Factory (CPF) belongs to Huizhou BYD Battery Co., Ltd.. Since 2005, company has been committed to the research and development of high- voltage relay products. The products expanded to film capacitors and fuses in 2007. In 2010, the products began to be used in batches of new energy vehicles. It is the earliest domestic similar products to be used in large quantities. At the same time, the products are used in large quantities in charging piles, energy storage and other new energy industries and industrial high-voltage equipment field. In 2017, BYD increases the intensity of external promotion of auto parts products. Relays, capacitors, fuses, ceramic covers and other automotive components gradually expanded the market share. After the customers’ mass application and long-term inspection in the market, our products have been highly recognized by mainstream OEMs and tier 1 suppliers. We are determined to become a respectable supplier of core components for new energy vehicles with world influence!
