The invention provides an elevator energy-saving emergency rescue device and a control method. The elevator energy-saving emergency rescue device comprises a traction machine, an elevator frequency converter, a bidirectional DC-DC converter, an energy storage device, a DC-AC inverter, an elevator controller and a power failure emergency controller. The high-voltage side of the bidirectional DC-DC converter is connected with a direct-current bus of the elevator frequency converter, and the low-voltage side of the bidirectional DC-DC converter is connected to the energy storage device; the direct current side of the DC-AC inverter is connected to the energy storage device, and the alternating current side of the DC-AC inverter is connected with the alternating current input end of the elevator frequency converter; the power failure emergency controller is connected to the DC-AC inverter, when power failure of a power grid is detected, the DC-AC inverter inverts direct current in the energy storage device into alternating current, the alternating current obtained through inversion is transmitted to the alternating current input end of the elevator frequency converter and the elevator controller, and the elevator frequency converter outputs the alternating current to the elevator controller. And the elevator runs to the flat layer, and the car door is opened.
