The invention discloses an electric vehicle thermal management system and a control method thereof and an electric vehicle. The electric vehicle thermal management system comprises a motor cooling circuit, a battery management loop and an air conditioning loop. The battery management loop comprises a PTC heating loop and a battery pack loop; the PTC heating loop is connected with the air conditioner loop; the PTC heating loop and the battery pack loop are connected through a second two-way four-position reversing valve; the battery pack loop and the motor cooling loop are connected through a first two-way four-position reversing valve; and the battery pack loop and the air conditioner loop are connected through a plate heat exchanger. The electric vehicle thermal management system is simple in structure, battery pack cooling liquid can be cooled through a heat radiator by controlling the reversing valve, so that the safety of a battery is guaranteed.
