The invention discloses a methanol range extending power system for a 40kW vehicle, and relates to the technical field of new energy vehicles. The range extender system comprises an engine, a generator and a GCU, when the range extender is started, a power battery supplies power to the GCU and drives the generator to start the engine, after the engine is started, the range extender is switched into a power generation mode and supplies power to a driving system or charges the power battery, and the driving system comprises a speed reducer, a driving motor and an MCU. The driving system receives energy of the range extender or the power battery to drive the vehicle to advance or retreat, and meanwhile electricity is generated and charged into the power battery when the vehicle is braked. Key core technologies such as corrosion and abrasion, low-temperature starting, spraying and combustion, thermal efficiency and the like of the methanol engine are emphatically improved; the invention relates to a lightweight, high-efficiency, high-specific-power, low-noise, energy-saving and environment-friendly permanent magnet synchronous motor key core technology. And the electric control system is a key core technology with strong compatibility, strong overload capacity and high reliability.
