The invention relates to a battery thermal management device of a hybrid power vehicle model, which comprises a battery cooling liquid loop, a closed refrigerating loop connected with an air conditioner refrigerant loop, and a closed heating loop connected with an engine cooling liquid loop and a WPTC (White Positive Temperature Coefficient) heating loop, the combined battery cooler is connected with the battery cooling liquid loop, the closed refrigerating loop and the closed heating loop; an air conditioner refrigerant output from the air conditioner refrigerant loop to the closed refrigeration loop exchanges heat with battery cooling liquid output from the battery cooling liquid loop in the combined battery cooler so as to realize battery cooling; and the engine cooling liquid or the heating working medium output into the closed heating loop from the engine cooling liquid loop or the WPTC heating loop exchanges heat with the battery cooling liquid in the combined battery cooler so as to realize battery heating. Air conditioner refrigeration can be achieved, waste heat of an engine can be utilized, WPTC heating can be used, and heat management of a battery is also considered.
