The invention discloses an efficient energy-saving internal heating vacuum baking intelligent system which comprises a preheating box group, a thermostat group, a cooling box group, a transitional box group, a plurality of brake valves, a transmission system and a control system, wherein the preheating box group comprises a plurality of preheating boxes sequentially connected in sequence; the thermostat group comprises a plurality of thermostats sequentially connected in sequence; the cooling box groups comprises a plurality of cooling boxes sequentially connected in sequence; the transitional box group comprises a first transitional box, a second transitional box, a third transitional box and a fourth transitional box; and the brake valves are arranged at two ends of the first transitional box, the second transitional box, the third transitional box and the fourth transitional box. Through the manner, the efficient energy-saving internal heating vacuum baking intelligent system adopts an internal heating system; independent intelligent temperature control is carried out on four internal surfaces; a lithium battery is uniformly heated to precisely control temperature so as to prevent the phenomena that a product is low in quality and is even scrapped due to the temperature problems including temperature overshoot and temperature instability; the entire baking system is full vacuum, less in heat consumption, high in heat efficiency and more efficient and energy-saving.
