Method for optimizing driving path according to energy consumption of pure electric vehicle

The invention discloses a method for optimizing a driving path according to energy consumption of a pure electric vehicle. The method comprises the following steps: acquiring driving energy consumed by the vehicle on each road section for overcoming driving resistance according to the running speed, the road section length and the road section gradient of the vehicle on each road section; throughdriving range tests in different environments, obtaining hundred-kilometer energy consumption of an air conditioner, hundred-kilometer energy consumption of a low-pressure accessory and hundred-kilometer recovered energy of an energy recovery system, and calculating vehicle energy consumption according to the total mileage of the recommended path; calculating the total energy consumption by addingthe sum of the running energy consumption to the vehicle energy consumption, comparing the energy output by the battery with the total energy consumption, and reasonably planning the driving path. The driving path is reasonab
