Abstract

The invention discloses an energy management method for a battery electric vehicle and belongs to the field of energy consumption control. The energy management method for the battery electric vehiclecomprises the following steps: 1, utilizing endurance mileage as a response variable, and determining parameters by utilizing DOE (Design of Experiment) to obtain the significant analysis results offactors; 2, carrying out energy consumption tests according to the significant analysis results of the factors, and determining corresponding energy management methods; 3, based on different road conditions and driving habits, utilizing the steps 1 and 2 to obtain energy management methods under corresponding conditions; and 4, in the use process of the vehicle, according to the acquired input parameters, invoking the corresponding energy management method to carry out energy management and realize maximum endurance mileage. The method solves the problems of heavy manual calibration workload,complicated post maintenance and high cost under the existing conditions.

Description

technical field [0001] The invention belongs to the field of energy consumption control, in particular to an energy management method for pure electric vehicles. Background technique [0002] At present, the energy management strategy of pure electric commercial vehicles is often unable to adapt to road conditions, drivers' driving habits and other influencing factors, and cannot self-learn to adapt to the working conditions of each customer during mass production. At the current stage, different energy management strategies are generally adopted for different working conditions. According to factors such as ambient temperature, accelerator opening and braking frequency, different energy feedback intensities and shift points are adopted to control the energy consumption of the vehicle and extend the life of the vehicle. driving mileage. However, the condition of each vehicle is different, and engineers need to go to the site to calibrate the relevant parameters of the vehic...
