1. A battery thermal management system, comprising: a battery, a battery thermal exchange structure, a pump, at least one first valve and three thermal adjustment components, wherein
the battery thermal exchange structure comprises a thermal exchange channel passing through the battery, and has a first port and a second port;
a first coolant circulation loop is formed via connecting a first port of the pump to the first port of the battery thermal exchange structure and connecting a second port of the pump to the second port of the battery thermal exchange structure, and a second coolant circulation loop is formed via connecting the first port of the pump to the first port of the battery thermal exchange structure and sequentially connecting the second port of the pump to the three thermal adjustment components and the second port of the battery thermal exchange structure, wherein the three thermal adjustment components comprise a heating component, a cooling component, and a radiating component which are connected in series;
the at least one first valve is set at one of two joint locations between the first coolant circulation loop and the second coolant circulation loop and is configured to switch between the first coolant circulation loop and the second coolant circulation loop to direct coolant flowing into either the first coolant circulation loop or the second coolant circulation loop.
