Abstract

The invention provides an energy recovery control method and system for an electric automobile. The method comprises the steps that the consumed power of an electric accessory of the electric automobile is collected, and the total consumed power of the electric accessory and a preset minimum power consumption threshold value of the electric accessory are judged; and when the total consumed power of the electric accessories is larger than a preset minimum power consumption threshold value, an energy recovery weighting control function of the electric automobile is started, and energy recovery of the electric automobile is controlled according to the weighted energy recovery power. And when the total consumed power of the electric accessories is smaller than or equal to the preset minimum power consumption threshold value, the energy recovery weighting control function of the electric automobile is closed. Therefore, when the electric accessory of the electric automobile is started and the consumed power of the electric accessory reaches the minimum power consumption threshold value, a user can start the energy recovery weighting control function to improve the energy recovery efficiency of the electric automobile and improve the driving range of the electric automobile.

Description

technical field [0001] The invention relates to the technical field of energy recovery, in particular to an energy recovery control method and system for an electric vehicle. Background technique [0002] At present, in order to reduce the more serious harm of fuel vehicles to the ambient air quality, electric vehicles have emerged as the times require. In order to make electric vehicles have a longer driving range during driving, the energy recovery system of electric vehicles plays an indispensable role. [0003] The energy recovery of electric vehicles means that when the electric vehicle is coasting or braking, the motor converts a part of the kinetic energy of the electric vehicle into electric energy, which provides energy for the electric accessories of the electric vehicle or stores it in the power battery to improve the electric energy. The process of the car's driving mileage. The driving range refers to the distance traveled by an electric vehicle when the power...
