The invention aims to provide a BEV (battery electric vehicle) thermal management system and a cooling liquid filling method thereof. The BEV thermal management system comprises an electric drive part thermal management sub-system and a passenger bin and battery thermal management sub-system. The electric drive part thermal management sub-system comprises a first overflow kettle, a first water pump, a radiator and an electric drive heat exchanging part, wherein one end of the radiator is connected with the first port of the electric drive heat exchanging part, the other end of the radiator is respectively connected with the first overflow kettle and the first port of the first water pump, and the second port of the electric drive heat exchanging part is respectively connected with the first overflow kettle and the second port of the first water pump. The BEV thermal management system and the cooling liquid filling method thereof have the advantages that effective thermal management of auto parts and accurate cooling liquid filling are achieved; the BEV thermal management system provides a good thermal management function for the electric drive part, a passenger bin and a battery, comfortableness of the passenger bin is guaranteed, and the electric drive part and the battery are enabled to be in an appropriate temperature range.
