Abstract

The invention discloses a power battery pack equalization system. The power battery pack equalization system comprises: an equalizer for acquiring a first parameter of a power battery pack; an information acquisition device for acquiring a second parameter of the power battery pack; and a control computer which is connected with the equalizer through a first communication bus and is connected with the information acquisition device through a second communication bus for receiving the first parameter and the second parameter, generating an equalization control command according to a preset equalization strategy and controlling the equalizer through the equalization control command to execute equalization processing on the power battery pack. Through the power battery pack equalization system, the problem of quite low bypass equalization efficiency of a power battery pack in the prior art is solved.

Description

technical field [0001] The invention relates to the field of power battery control, in particular to a power battery equalization system. Background technique [0002] With the development of electric vehicles using clean energy in the field of urban public transportation, countries around the world have launched research and development and application of electric vehicles and their charging facilities. In order to meet the actual needs of electric vehicle energy storage, power batteries often need to be used in series or in parallel. However, in the production process, the initial performance of the power battery will be inconsistent due to the uneven process, ingredients and impurity content, such as the capacity, internal resistance, charging efficiency and self-discharge characteristics of the power battery. Therefore, during the use of the power battery pack, the inconsistency among the power batteries gradually leads to the deterioration of the characteristics of som...
