The invention provides a double-source electric power steering pump and a new energy vehicle. The double-source electric power-assisted steering pump comprises a double-acting steering oil pump (1) and a power-assisted steering motor (2), the power-assisted steering motor (2) is used for providing steering power for the double-acting steering oil pump (1), the power-assisted steering motor (2) is connected with a high-pressure controller and a low-pressure controller (3), the high-pressure controller controls a high-pressure power source to supply power to the power-assisted steering motor (2), and the low-voltage controller (3) controls the low-voltage power supply to supply power to the power-assisted steering motor (2) after the high-voltage battery fails. According to the double-source electric power-assisted steering pump, the problem that a single-source power-assisted steering pump cannot continuously provide assisted power after high-voltage power failure can be solved.
