Abstract

The invention relates to the technical field of energy conversion, in particular to a power energy management system and a management method thereof. The power energy management system connected to acharging device externally is composed of a long-acting energy storage device, a dynamic buffer energy storage device and an energy center management and control module. The charging device is connected with the dynamic buffer energy storage device and the energy center management and control module electrically. The invention aims at providing a power energy management system and a management method thereof. With the system provided by the invention, problems of slow charging, energy regeneration and energy recovery of the electrical vehicle can be solved.

Description

technical field [0001] The invention relates to the technical field of energy management and conversion, in particular to a power energy management system and a management method thereof. Background technique [0002] At present, there are two important bottlenecks in the application of pure electric vehicles: first, the battery life is small; second, the charging time is long. These two problems restrict the promotion of the pure electric vehicle market. The charging speed depends on the size of the charging current, but as a lithium battery as the main energy storage device, high-current charging can only be carried out within a certain charging range. Once this range is exceeded, charging with a high current will cause the lithium battery to overheat, or even explode. Therefore, the general lithium battery charging mode is to perform high-current fast charging when pre-charging is completed, and then switch to low-current slow charging when a certain state of charge is r...
