The invention provides an electric vehicle low-temperature driving range test regulation development method. The method comprises the following steps: data acquisition and processing; determining a test temperature; determining a test condition TTC; determining a test method; calculating a test result weighting factor; and according to the typical working condition of the test working condition TTC, the test temperature, the test method and the test result weighting, a typical vehicle use scene low-temperature test procedure is formed. The method has the beneficial effects that the low-temperature test regulation conforming to the electric vehicle use scene is established through the method, the scene applicability is expanded, the test result deviation is small, and meanwhile, the low-temperature driving mileage degradation amplitude of vehicle types with various purposes is quantified. The method is of great significance in relieving mileage anxiety of consumers, reducing research and development test cost of enterprises and providing favorable means for government department supervision.
