Abstract

The invention provides a vehicle-mounted composite power supply control system and method for an electric vehicle. The system includes a three-dimensional map information processing and positioning system, a dynamic path planning system, a path-based vehicle energy demand unit, and a composite power distribution system. The invention solves the technical problem of low energy utilization efficiency of the existing vehicle-mounted composite power supply system. The system can make full use of real-time traffic data and three-dimensional map information, adopt dynamic path planning technology and HESS power distribution multi-objective optimization method, fully consider the influence of path elevation information on HESS power distribution, and improve the energy utilization efficiency of vehicle-mounted HESS.

Description

technical field [0001] The invention belongs to the field of control of a vehicle-mounted composite power supply of an electric vehicle, and more particularly relates to a control system and method for a vehicle-mounted composite power supply of an electric vehicle. Background technique [0002] The advantages of supercapacitors and batteries in the hybrid power supply system (HESS) can complement each other, which can meet the dual needs of power source power and energy in the process of starting, accelerating and climbing. The supercapacitor in this system can maximize the recovery of regenerative braking energy, significantly improving the efficiency and performance of HESS. For example: the applicant Jiangsu University applied for a composite power supply control system and its switching method under different working conditions on September 22, 2016. In this application, the energy management system communicates with the vehicle controller and the first The sampling de...
