Chinese electric vehicle manufacturer Zeekr has partnered with US chipmaker onsemi to secure a decade-long supply of silicon carbide power semiconductors, which enable greater powertrain efficiency and longer driving ranges than devices made with traditional silicon wafers. However, the supply volumes and financial scope of the agreement were not disclosed in a statement released on Wednesday. Rival Li Auto reaffirmed its plans to incorporate SiC semiconductors into its next-generation powertrain systems for future models on April 18, stating that its pure battery EV will be capable of traveling 400 kilometers (249 miles) after just 10 minutes of charging. Geely’s premium EV arm aims to deliver 140,000 Zeekr vehicles this year. [onsemi release]
