The company said in a statement posted on its Weibo social media account that the joint investigation team had conducted an investigation and analysis of the battery, software, manufacturing data and vehicle history.
The investigation found no system defect, and the initial findings show the incident was caused by a single battery module located at the front of the vehicle, Tesla said.
Japanese battery manufacturer Panasonic (6752.T) supplies Tesla with battery cells, but not modules, which are a group of cells joined together.
