Abstract

The invention belongs to the technical field of new energy electric vehicles, and particularly discloses an energy management method and system for a new energy electric vehicle storage battery composite power supply, and the method comprises the following steps: carrying out the research of the overall structure of a new energy electric vehicle storage battery composite power supply system; dividing the module into a plurality of sub-modules for design; super capacitor parameters are selected and optimized according to the actual situation of the electric vehicle, a new energy electric vehicle storage battery composite power system structure is built, and software and hardware design of a control system is carried out; and establishing a mathematical model of the composite power supply system, designing an energy management method of the composite power supply system, performing optimization, and determining a final energy management method of the composite power supply system. The scheme improves the energy utilization rate of the hybrid power supply. The storage battery can be protected, the driving range of the electric vehicle can be increased, and early-stage preparation work is made for the hybrid power supply new energy electric vehicle to go to the market.

Description

technical field [0001] The invention belongs to the technical field of new energy electric vehicles, and in particular relates to an energy management method and system for a battery composite power supply of new energy electric vehicles. Background technique [0002] Ultracapacitor (Ultracapacitor) is a new type of energy storage element developed recently between batteries and electrostatic capacitors. It is a physical secondary power supply with super storage capacity and strong pulsating power. It has a much higher energy density than an electrostatic capacitor and a much higher power density than a battery. Its capacity can reach tens of thousands of farads. It can be charged to any voltage value at a very fast speed within the rated voltage range. It can release all the stored electric energy, and there is no problem of damage caused by rapid charging and discharging of the battery. It is very suitable for short-term high-power applications. Utilizing its advantages o...
