Abstract

The invention provides a lithium battery and super capacitor dual-energy power distribution control system and method. The lithium battery and super capacitor dual-energy power distribution control system comprises a motor needed power collection module, an energy management center, a battery pack and the super capacitor. The motor needed power collection module is connected with the signal input end of an energy management center. The signal output end of the energy management center is connected with the battery pack and the super capacitor. The lithium battery and super capacitor dual-energy power distribution control system and method have the advantages that the structure is simple, using is convenient, the depth of discharge of the battery pack is reduced by means of the rapid charging characteristic of the super capacitor, the number of service times of the battery pack is improved, the service life is prolonged, the driving mileage is increased by 50%, and energy is saved by 30% or over in the starting and stopping processes.

Description

technical field [0001] The invention relates to the technical field of electric vehicle power systems, in particular to a dual-energy power distribution control system and method of a lithium battery and a supercapacitor. Background technique [0002] Compared with traditional fuel vehicles, electric vehicles have the advantages of low pollution, high efficiency, can use a variety of renewable energy sources, low noise, and are more conducive to vehicle control and intelligence. The potential and advantages of electric vehicles make them on the way a path of rapid development. As a key component of electric vehicles, the development and optimization of on-board power supplies has been a research hotspot in recent years. But in the process of optimization, the performance of the system will restrict each other, and the improvement of one will reduce the performance of the other. The technical problem of the inability to balance the specific energy and specific power of the ...
