The invention discloses a battery thermal management system based on combination of a flat plate type pulsating heat pipe and a liquid cooling system and a temperature control method, and relates to the technical field of electric vehicle battery thermal management systems. Through cooperation of the flat plate type pulsating heat pipe and the liquid cooling system, the temperature equalization performance of the flat plate type pulsating heat pipe is brought into full play, the starting time of the cooling liquid pump is delayed, and the maximum temperature difference of the whole battery module is reduced. The flat plate type pulsating heat pipe and the liquid cooling channel plate are vertically arranged in a staggered mode, the temperature difference between the theoretical evaporationend and the theoretical condensation end of the pulsating heat pipe is more obvious, and the starting performance of the pulsating heat pipe is enhanced. Compared with traditional liquid cooling systems, the energy consumption of the liquid cooling system can be reduced, the temperature difference between an inlet and an outlet of the liquid cooling system is close, the overall heat exchange coefficient of the liquid cooling system is increased, a faster cooling effect can be achieved on a battery module, and the service life of a battery is prolonged.
